Answer:
$8
Step-by-step explanation:
Let x represent the amount of money he has to save each week.
We can use this to set up an equation:
[tex]7x=56[/tex]
Now, we have to "isolate the variable". This means we must have a resulting equation of [tex]x=\text{something}[/tex].
In this case, we can use the Division Property of Equality to divide both sides by 7:
[tex]\frac{7x}{7}=\frac{56}{7}\\x=8[/tex]
Therefore he must say $8 each week for 7 weeks so that he can buy the guitar.

What is the greatest common factor (GCF) of 15 and 6x?
Answer:
3
Step-by-step explanation:
Factors of 15: 1, 3, 5, 15
Factors of 6x: 1, 2, 3, 6, x
Therefore, the greatest common factor (the highest factor that they both share) is 3
Factor = f
——————
f15 = 1, 3, 5, 15
f6 = 1, 2, 3, 6, x
So the answer is 1 and 3, but we need to give the answer from the highest number. The highest number is 3.

Answer:
138°
Step-by-step explanation:
X = 180° - 42° [Sum of angles in a triangle]
X = 138°
Answer: 48 degrees.
Step-by-step explanation: The key to finding a missing interior angle is to have all the angles add up to 180. The corner with the square means that the angle is 90 degrees. An angle has been provided, which is 42 degrees. Now, we can add 42 and 90, and you have 132 degrees so far. Now, we need to subtract 132 from 180 and we have 48 degrees. That is your value of x.

A pet store kept their hamsters in cages with 6 per cage. For their Christmas sale they put out 6 cages and end
up selling ait but 9 hamsters. How many hamsters did they sell during their Christmas sale?
Answer:
The answer would be 27
Step-by-step explanation:
If it is 6 per cage that would mean it is 6 times 6 (since they put out 6 cages) which is 36. They sold all but 9. The question is askin how many hamsters did they sell. So you would do 36-9 which is 27

Answer:
(x, y) -> (2.5x, 2.5y)
Step-by-step explanation:
To find which equation is correct, first, let's find a similar point of Figure J and Figure K.
Figure J: (-3, -2). Figure K: (-7.5, -5)As you can see, Figure J was enlarged by a SF of 2.5 because -3 x 2.5 = -7.5, and -2 x 2.5 = -5.
Therefore, the answer is (x, y) -> (2.5x, 2.5y).

A store display will have 6 rows, with 12 containers in each row.
If 39 containers has been set up so far, explain how to find the
number of containers that still need to be set up. Then solve the
problem
Answer:
A total of 72 containers need to be set up. If 39 are already placed then there are 33 left. You multiple the number of rows by the number of containers per row to find your total and subtract what has already been done.
5+(3×n)=5
Which value of n makes the number sentence true?
1
0
−3
−5
Answer:
0 makes the statement true.
explanation:
5+(3×n)=5
5 + 3n = 5
3n = 5 - 5
3n = 0
n = 0
check:
5+(3×0) = 5
5 + 0 = 5
5 = 5
Both sides equal, therefore statement true.

1. since A^2= 36x^2, a=?
2. since b^2= 49, b=?
Answer:
D
Step-by-step explanation:
36x² - 49 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
then
36x² - 49
= (6x)² - 7²
= (6x - 7)(6x + 7)
Thus 6x - 7 is a factor of the expression
We need to simplify the expression 36x² - 49 , but let's recall the identity which is the main key to solve this question i.e
[tex]{\boxed{\bf{a^{2}-b^{2}=(a+b)(a-b)}}}[/tex]So , here we can write the above expression as
[tex]{:\implies \quad \sf (6x)^{2}-(7)^{2}}[/tex]
Now , using the above identity this can be written as :
[tex]{:\implies \quad \sf (6x-7)(6x+7)}[/tex]
So , here both (6x-7) and (6x+7) are factors of 36x²- 49 , but in the options their is only 6x - 7.
Hence , Option D) 6x - 7 is correct
As here , 36x² = (6x)² = a² , so a = 6x and as 49² = 7² = b² , so b = 7

Find the value of aBc
Compound shape
Answer:
∠ ABC = 75°
Step-by-step explanation:
using the sine ratio in right Δ ABD
sin ABD = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AD}{AB}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex] , then
∠ ABD = [tex]sin^{-1}[/tex] ( [tex]\frac{1}{2}[/tex] ) = 30°
Using the sine ratio in right Δ CBD
sin CBD = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{CD}{BC}[/tex] = [tex]\frac{3}{3\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] , then
∠ CBD = [tex]sin^{-1}[/tex] ( [tex]\frac{1}{\sqrt{2} }[/tex] ) = 45°
Then
∠ ABC = ∠ABD + ∠ CBD = 30° + 45° = 75°

In order to subtract these fractions, we should turn the first fraction into an improper fraction.
What is an improper fraction?
An improper fraction is a fraction whose numerator is greater than its denominator.
How to turn a mixed number into an improper fraction?
Multiply the whole number by the denominator.- Multiply 1 times 8
2. Add the numerator.
- Add 7 to the product of 1 and 8 (which, of course, is equal to 8)
8+7=15
Therefore, we have
[tex]\bold{\displaystyle\frac{15}{8} -\frac{3}{8}}[/tex]
Now all we have to do is subtract the numerators!
[tex]\bold{\displaystyle\frac{12}{8}}[/tex]
Surprise! This fraction can be reduced:
[tex]\boxed{\boxed{\bold{\displaystyle\frac{3}{2}}}}[/tex]
Hope everything is clear.

X=?
(step by step)
Answer:
7x-14=2x+11
Step-by-step explanation:
Collect like terms
7x-2x=11+14
5x=25
Divide both sides by the coefficient of x(5).
x=25/5
x=5
Answer:
x=5
Step-by-step explanation:
The first thing we need to do in this equation is to get both of the x variables on the same side.
How do we do this you might ask? Well, need to cancel out the 2x so all we have left is one x variable. We can do this by subtracting 2x from each side.
The important thing to remember when solving equations like these is that whatever you do to one side, you MUST do to the other side.
2x-2x is 0 so that cancels out the 2x on the right side. 7x-2x=5x so we are left with that for our left side.
Now, we have to get rid of the constants (the non-variable numbers)
Let’s cancel out the 14 on the left side so the x is still by itself.
Add 14 to -14 to cancel it out. Do the same to the right side. 14+11=25 so that 25 is what we are left with on the right side.
Our equation becomes 5x=25
Now we have to completely isolate the x with no coefficient. We do this by dividing 5 by each side. But remember the rule, whatever you do to one side, you must do to the other. So we divide 25 by 5 as well.
5x/5 is x and 25 divided by 5 is 5
So our final answer is…
X=5

Find an equation for the perpendicular bisector of the line segment whose endpoints are (6,9) and (2,5).
Answer:
x + y = 11
Step-by-step explanation:
The perpendicular bisector goes through the midpoint of the segment and has a slope that is the opposite reciprocal of the slope of the segment. The midpoint is ...
M = (A+B)/2 = ((6, 9) +(2, 5))/2 = (6+2, 9+5)/2 = (8, 14)/2
M = (4, 7) = (Mx, My)
The slope can be found from the differences of the coordinates of the two points:
(Δx, Δy) = (2 -6, 5 -9) = (-4, -4)
Factoring out -4, this becomes
(Δx, Δy) = (1, 1)
__
These values can be used directly to form the equation of the perpendicular line:
(Δx)(x -Mx) +(Δy)(y -My) = 0
1(x -4) +1(y -7) = 0
x + y = 11 . . . . . . . . . add 11 and simplify
___
Additional comment
Using "standard form" for the equation, we don't actually need the value of the slope. If you were to use point-slope form or slope-intercept form for the equation of the line, then you would need to know the slope of the segment is ...
m = Δy/Δx = 1/1 = 1
and the slope of the perpendicular is ...
m' = -1/m = -1/1 = -1
