Step 1: Subtract 100 from both sides of the equation.
Step 2: Simplify.
Step 3: Subtract 25x from both sides of the equation.
Step 4: Simplify.
Step 5: Divide both sides of the equation by the same term.
Step 6: Simplify.
X=10 :)
Answer:
x = 10Step-by-step explanation:
In this question we are given an equation that is 22x + 100 = 25x + 70. And we are asked to find the value of x .
Solution : -
[tex] \longmapsto \:22x + 100 = 25x + 70 [/tex]
Step 1 : Subtracting 100 from both sides :
[tex] \longmapsto \:22x + \cancel{100} - \cancel{100} = 25x + 70 - 100[/tex]
On further calculations we get :
[tex] \longmapsto \: 22x = 25x - 30[/tex]
Step 2 : Subtracting 25x from both sides :
[tex] \longmapsto \:22x - 25x = \cancel{ 25x} - \cancel{25x }- 30[/tex]
On further calculations we get :
[tex] \longmapsto \: \cancel{- }3x = \cancel{ - }30[/tex]
Step 3 : Dividing with 3 on both sides :
[tex] \longmapsto \: \frac{ \cancel{3}x}{ \cancel{3}} = \cancel{\frac{30}{3} }[/tex]
On further calculations we get :
[tex] \longmapsto \: \purple{\boxed{ \frak{x = 10}}}[/tex]
Henceforth , value of x is 10 .Verifying : -
We're verifying our answer by substituting value of x in given equation . So ,
22x + 100 = 25x + 7022 ( 10 ) + 100 = 25 ( 10 ) + 70220 + 100 = 250 + 70320 = 320L.H.S = R.H.S Hence, Verified.Therefore, our value for x is correct .
#Keep LearningIn the diagram JKL ~ MNO, what is the length of side KL?
Will give brainliest PLS ANSWER QUICK
Answer:
7.5
Step-by-step explanation:
Ok so this is how I got it:
Since we know the lengths of sides NO, MN, and JK, but we don't know the length of KL, we can use what we know.
To get from MN to JK, we multiply MN (2) by 1.5 to get 3. So you can go the same thing to get from NO to KL.
Just go ahead and multiply 5 by 1.5
5 × 1.5 = 7.5
Hope this helps!
Answer:
KL = 7.5
Step-by-step explanation:
MN : JK = NO : KL
⇒ 2 : 3 = 5 : KL
[tex]\implies \dfrac23=\dfrac{5}{KL}[/tex]
⇒ 2 · KL = 5 · 3
⇒ 2(KL) = 15
⇒ KL = 15 ÷ 2
⇒ KL = 7.5

Next, the team wants to explore how it can change the steepness of the curved pit.
Identify how the graph of each equation compares with the graph of the parent quadratic equation, y = x2.
Drag the equations to the correct location on the chart. Not all equations will be used.
Given that the parent function, y = x², has a leading coefficient of 1, the
following are the comparisons of the equations with the parent functions;
[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]
How can the correct location of each equation be found?The parent function is y = x²
The leading coefficient of the parent function = 1
The steepness of a quadratic equation is given by the value of the
leading coefficient.
When the leading coefficient is larger than 1, we have;
The function is steeper than y = x²
When the leading coefficient is a fraction larger than 0 but lesser than 1, we have;
The function is less steep than y = x²
Which gives;
[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]
The function y = -x² is inverted has the same steepness as y = x², but will not be used.

Tara has two bags of M&M’s. The first bag contains 6 red, 5 blue, and 4 green M&M’s. The second bag contains 3 red, 2 blue, and 4 green M&M’s. Tara will select one M&M from each bag. What is the probability that Tara will select a blue M&M from each bag?
Answer:
29.6667%
Step-by-step explanation:
In first bag there is 15 M&M's ANd second bag has a total of 9 M&M's so that means there are a total of 24 M&M's.
In the first bag there is 5 blue M&M's and in the second bag there is a total of 2 blue M&M's so there is a total of 7 blue M&M's all together.
so there are 7/24 M&M's ( what were going to do it convert it into percents.
To do this were going to use these steps.
were going to divided the number of blue M&M's by the total of M&M's all together so 7 divided by 24=?And then next we are going to multiply the result by 100 which=?Calculations
7 divided by 24=0.291666.

Answer:
9
Step-by-step explanation:
they are not in the middle so it has to be 9-8 i feel like its 9
hope this helps!
The distance minute hand tracked from 2 to 6 is 5.23 inches.
What is the measure of each integer step in a clock?A clock can be thought of as a circle having 12 steps and we know that circle is 360°,
So, the measure of each integer step of a clock is 30°or π/12 rad.
We know the circumference of a circle is 2πr.
From 2 to 6 the minute hand rotated (4×30°) = 120° = 2π/3 rad.
We know arc length(S) = r×Ф.
∴ The distance minute hand tracked is = (2.5)×(2π)/3 inches.
= 5.23 inches.

A group of friends wants to go to the amusement park. They have $131.75 to spend on parking and admission. Parking is $18, and tickets cost $22.75 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.
Answer:
3 people
$9.5 left over
Step-by-step explanation:
pp = 18 + 22.75
pp = 40.75
total people who can go = 131.75/pp
tp = 131.75/pp
tp = 3 remainder $9.5
(this is if they all arrive in individual cars)
The number of people that can go to the amusement park are 5 .
Concept:First, we need to find the amount left after deducting parking charges. Then the remaining amount can be divided by the price of one ticket to find out how many persons can buy the ticket from the same amount.
How to solve the given problem?The parking charges are $18 and the ticket costs $22.75 per person.So amount left after parking charges = $131.75 -$18 = $113.75To find the number of persons, let x be the no of tickets that can be purchased from the given amount.So the expression can be framed as 22.75x = 113.75.On solving the expression, we get x = 5 nos.Thus, 5 number of persons can go to the amusement park.

Anna ate 5/8 of an orange and gave the other 3/8 to her brother. Which equation can be used to find the difference between the amount Anna ate and the amount she gave her brother?
Answer:
B
Step-by-step explanation:
First of all the equation is subtracttion since they used to word *difference* which indicates subtract. To find the different between how much Anna at and how much she gave her brother we would subtract 5/8 by 3/8.
to solve this equation ( 5/8 - 3/8 ) the denominator of both fractions have yo be the same and that is true for this equation. Then you would subtract the numerators and keep the denominator the same. So the answer is 2/8

a rectangle has a length of 9 inches and an area of 48 inches. it’s width, w, is unknown. explain why the following equation cannot be solved to find the correct width of the rectangle? w+9=48
Answer:
This equation cannot be solved to find the correct width of the rectangle because the formula for the area of a rectangle is area = base times the height. Therefore, you can't just simply subtract 9 from 48 to get the width. Instead, you have to divide 48 by 9 to find the width, since 48 is the area and 9 is the length.

Answer:
3.75 feetStep-by-step explanation:
If 5 cm on the model = 4 feet in real
Then, what does 1 cm on the model = in real?
5/4=1.25
So, 1 cm on the model = 1.25 ft
Now, what does 3cm long in the model = to in real?
1.25x3=3.75

2x - y = 2
Answer:
Point slope form of the equations:
y = -3x + 8
y = 2x - 2
Solution to the system of equations:
(x, y) ==> (2, 4)
Step-by-step explanation:
6x + 2y = 16
2x - y = 2
6x + 2y = 16
2(2x - y = 2) ==> 4x - 2y = 4
6x + 2y = 16
4x - 2y = 4
10x = 20
/10 /10
x = 2
Now, we solve for y:
6x + 2y = 16
6(2) + 2y = 16
12 + 2y = 16
-12 -12
2y = 4
/2 /2
y = 2
(x, y) ==> (2, 2)
Point-slope forms:
6x + 2y = 16
-6x -6x
2y = -6x + 16
/2 /2
y = -3x + 8
2x - y = 2
-2x -2x
-1y = -2x + 2
