Find the value of x if the perimeter is 30. X+3, x, 2x-1
Step-by-step explanation:
Perimeter represents the sum of all of the sides adding.
The problem is stating that;
[tex]30 = x + x + 3 + 2x - 1[/tex]
Combine like terms;
[tex]30 = 4x + 2[/tex]
Subtract from both sides;
[tex]28 = 4x[/tex]
Divide each side by 4;
[tex]7= x[/tex]
Check;
[tex]30 = 7 + 7 + 3 + 2(7) - 1[/tex]
[tex]30 = 17 + 14 - 1[/tex]
[tex]30 = 31 - 1[/tex]
[tex]30 = 30\checkmark[/tex]

Solve for each equation 3 1/4 = 1/2 + w
Answer:
w = - [tex]\frac{58}{31}[/tex]
Step-by-step explanation:
3 1/4 = 1/2 + w
Cross Multiply
31(2 + w) = 4
Divide both sides by 31
[tex]\frac{31(2 + w)}{31}[/tex] = [tex]\frac{4}{31}[/tex] (simplify) -> 2 + w = [tex]\frac{4}{31}[/tex]
Subtract 2 from both sides
2 + w - 2 + [tex]\frac{4}{31}[/tex] - 2 (simplify) -> - [tex]\frac{58}{31}[/tex]
w = - [tex]\frac{58}{31}[/tex]
In which number does the digit 3 have a value that is ten times greater than the value of the digit 3 in the number 145,317
Answer:
Step-by-step explanation:
The value of the digit "3" in "156.32" is 3/10 (3 tenths). 10 times that value would be 3 (3/10 * 10 = 3). So now we need a number that has the digit "3" in it and the value of that digit is "3".
How about 143.26? The digit "3" is in the ones place and so its value is 3*1 or 3. The rest of the number is just made up, nothing special about any of the other numbers.
The value of digit 3 in 156.32 is 3/10 (3 tenths).
10 times that value would be 3 (3/10 * 10 = 3).
What is the value of digits?The face value of a digit is the magnitude that it possesses naturally. It is independent of the digit's position in the number.
The place value of a digit depends on its position in the number.
So now we need a number that has the digit 3 in it and the value of that digit is 3.
How about 143.26. The digit 3 is in the one place and so its value is 3*1 or 3.
The rest of the number is just made up, nothing special about any of the other numbers.

Find the equation of the line that is parallel to the line y = 2x – 2 and passes through the point (5, -1). Write the equation in point- slope form.
Solution:
We know that:
Equation of parallel line: y = 2x - 2Since the parallel line has a slope of 2, the equation of the original line will also have a slope of 2. Now, let's use point-slope form to find the equation.
y - y₁ = m(x - x₁)y - (-1) = 2(x - 5)y + 1 = 2(x - 5)Thus, the equation of the line in point slope form is y + 1 = 2(x - 5).

(–2) + (–20) step by step
Answer:
-22
Step-by-step explanation:
Step 1: Subtract 20 from -2
(-2) + (-20) is the same thing as -2 - 20When subtracting a negative value from a negative number, you keep the negative sign and just add the two numbers.- 2 - 20 = -22Therefore, the answer is -22.

the values of q decrease as the values of p increase.
this indicates an inverse relationship between the quantities, that is
q = [tex]\frac{k}{p}[/tex] ← k is the constant of variation
to find k use any ordered pair from the table.
using q = 16 when p = 3 , then
16 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )
48 = k
q = [tex]\frac{48}{p}[/tex] ← equation of variation
(4)
the values of q increase as the values of p increase.
this indicates the quantities are in direct variation, that is
q = kp ← k is the constant of variation.
to find k use any ordered pair from the table.
using q = 2 when p = 6 , then
2 = 6k ( divide both sides by 6 )
[tex]\frac{2}{6}[/tex] = k , that is
k = [tex]\frac{1}{3}[/tex]
q = [tex]\frac{1}{3}[/tex] p ← equation of variation

In a direct variation, y=8 when x=2. Write a direct variation equation that shows the relationship between x and y.
Answer:
y=4x
Step-by-step explanation:
Direct Variation means y=kx where k is a Constant
since y=8 when x=2
y=kx --> 8=k*2 then k=4
Then y=4x

One just needs to go to his/her calculator and solve it
Answer:
0.04566210...(8-digit repeat)
Step-by-step explanation:
The quotient of 6 ÷ 131.4 is shown in the attachment. The remainder at the bottom matches the original dividend, so the quotient will be repeating:
[tex]\dfrac{6}{131.4}=0.\overline{04566210}[/tex]
The division process starts by rewriting the problem to integer division:
60/1314
(If you like, you could further reduce this to 10/219 by removing a common factor of 6 from numerator and denominator.)
At each stage, the quotient digit is multiplied by the divisor and the result subtracted from the dividend to get a new dividend. Careful attention to the vertical alignment of digits will help ensure that quotient digits have their proper place value.

Carl or felipa ( I need a explanation aswell ) And I’ll give thanks and brainliest!!!!
Answer:
Carl is incorrect, he didn't write an equivalent expression and he didn't use the distributive property in the equation.
Step-by-step explanation:
When solving equations, we use PEMDAS
P = Parenthesis
E = Exponent
M = Multiply
D = Divide
A = Add
S = Subtract
So lets solve the equation then:
6 - 4 (3 - 6x) + 12x
Use the distributive property to multiply −4 by 3 and -6x
6 - 12 + 24x + 12x
Subtract 12 from 6 to get −6
-6 + 24x + 12x
Combine 24x and 12x to get 36x
-6 + 36x
So, -6 + 36x is the answer
And the reason why Felipa is correct, is because Felip wrote an equivalent expression, she correctly multiplied -4 (3 - 6x) before adding or subtracting and she combined like terms correctly.
The reason why Carl is incorrect, is because he didn't write an equivalent expression and he didn't use the distributive property in the equation.
