Answer:
She spent $22 on food, and $48 on clothes.
Step-by-step explanation:
Let's define the variables:
C = amount of money that Deborah spent on clothes
F = amount of money that Deborah spent on food.
We know that she spent in total $70, then we have the equation:
F + C = $70
And we know that she spent $26 more on clothes than on food, then we have the equation:
C = F + $26
This means that we have a system of equations:
F + C = $70
C = F + $26
To solve these type of systems, we usually start by isolating one variable in one of the equations. Here we can see that C is already isolated in the second equation.
Now we can replace it in the first equation.
F + (F + $26) = $70
Now we can solve this for F.
2*F + $26 = $70
2*F = $70 - $26 = $44
F = $44/2 = $22
So she spent $22 on food.
Now we can use the equation:
C = F + $26
To find how much she spent on clothes, where we need to replace F by the value we found.
C = $22 + $26 = $48
She spent $48 on clothes.

A scale drawing of Julie's living room is shown below:
A rectangle is shown. The length of the rectangle is labeled as length equal to 8 cm, and the width is labeled as width equal to 6 cm.
If each 2 cm on the scale drawing equals 4 feet, what are the actual dimensions of the room?
Length = 16 feet, width = 12 feet
Length = 10 feet, width = 8 feet
Length = 32 feet, width = 24 feet
Length = 14 feet, width = 12 feet
Answer:
Length = 16 feet, width = 12 feet
Step-by-step explanation:
The length is 8 cm. So divide this by 2 to find out how many 2 cm are in 8 cm. You get 4. Multiply 4 x 4 (ft) to find out the real length. This means the length is 16 feet.
Do the same steps with the width. The real length is 12 feet.
Hope it helps!

Which answer choice gives three lengths that WILL form a triangle when put
together?
5,7,13
12, 18, 35
107,8,9
4.5.10
Answer:
none of them
Step-by-step explanation:
in order for them to be triangle lengths the two shorter size added together have to be greater than the longest side and in each answer choice if you add the two shorter sides none of them are greater than the longer side if that makes sense
Answer: what you need to find is the one where the two lowest numbers add up to be bigger than the biggest number. For example, if it was 3,7,5 then those could be right because 5+3=8 and 8 is bigger than 7. It is supposed to be that any two added is bigger than the third, but it's mist important that the smaller numbers equal more than the third

Step-by-step explanation:
3x² + 9x + 4x + 12 = 3x² + 13x +12 = (x+3)(3x+4)
if 3x² + 9x + 4x + 12 = 0 x = -3 or x = - 4/3
A shoe distributor sells a particular pair of shoes to a store for $42.80. The store then sells this pair of shoes to a customer at a 35% markup. How much money does the store make from selling one pair of shoes to a customer?
Answer:
$14.98
Step-by-step explanation:
The store bought the pair of shoes for $42.80.
If the store sells the pair of shoes at a 35% markup, then it is selling it at:
([tex]\frac{35}{100}[/tex] × 42.80 ) + 42.80 = 14.98 + 42.80 = $ 57.78
To calculate how much money the store is making from selling this pair of shoes:
57.78 - 42.80 = $14.98
The store would be making $14.98 for selling one pair of shoes to a customer.

The diagonals of rectangle. QRST intersect at P. Given that m<PTS = 34° and QS=10 , find QP.
Answer:
QP = 5
Step-by-step explanation:
since QRST is a rectangle, and QRST intersect at P, then QTS and QRS are right triangles.
because <T is a right angle, line TR passes through the midpoint of line QS, therefore 2(QP) = QS
10/2 = 5
By the property of diagonal in a rectangle are equal and bisect each other measure of QP is 5 units.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
Given, QRST is a rectangle, QS and RT are the diagonals of the rectangle
QRST.
By properties of rectangles, we know a rectangle is a parallelogram in which opposite sides are equal and diagonals bisect each other.
Given, QS is 10 units and QS = 2QP.
10 = 2QP.
QP = 10/2.
QP = 5.

Equation=
x=
Answer:
3x - 1 = 71
3x = 72
x = 24
Step-by-step explanation:
Answer:
Step-by-step explanation:
Simplifying
3x + -1 = 71
Reorder the terms:
-1 + 3x = 71
Solving
-1 + 3x = 71
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + 1 + 3x = 71 + 1
Combine like terms: -1 + 1 = 0
0 + 3x = 71 + 1
3x = 71 + 1
Combine like terms: 71 + 1 = 72
3x = 72
Divide each side by '3'.
x = 24

x = 24

72 millimeters to 3 meters
The ratio is 24:1000 or 0.024.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
72 millimeters to 3 meters
Now, Convert 3 meter to millimeter
3 meter= 3 x 1000
= 3000 mm
Then, ratio is
= 72 / 3000
= 24/1000
= 0.024

Factor out the greatest common
factor: -16x? + 12x?
Answer:
4x is the greatest common factor of those two.
Step-by-step explanation:
(-16x + 12x)
4x (-4 + 3)
4x is the GCF
Why you may ask is 4x the GCF because when you divide 4x from both you're left with -4 + 3...... you can't take out the negative from the 16 because when you check your work negative 4x times 3 gives you negative 12x which isn't the equation you started with. So positive 4x times 3 give you 12x.

What is the measure of angle QZP
Answer:
22 degrees
Step-by-step explanation:
so if we take this here we know for sure that DZP is equal to 90 degrees
so DZP is split by QZD and QZP
so we take the 90 degrees we know for sure and then we take the two angle measurements we know
and we make this equation
9x + 5 + 3x + 1 = 90
and then we simplify this and it leaves us with
12x + 6 = 90
12x = 84
x = 7
so now that we have what x equals we plug that into QZP in order to find the actual measurement of this angle
3x + 1
3 (7) + 1
21 + 1
leaving us with our answer 22 degrees
and if you want to double check this answer just do the same thing we just did with QZD and plug in x into the equation and then add our answer 22 and the other answer you get for QZD and if that adds up to 90 then that is correct!

Easy Cooking is a cooking supply company. Last year, the company sold a total of 5,340 ovens. This year, they sold 7,743 ovens. What is the percent of increase in the annual sales of ovens?
Answer:
45%
Step-by-step explanation:
Given data
Last year, the company sold a total of 5,340 ovens
This year, they sold 7,743 ovens
Percent increase= final-initial/initial*100
substitute
Percent increase= 7,743-5,340/5,340*100
Percent increase= 2403/5,340*100
Percent increase=0.45*100
Percent increase=45%
Hence the increase is 45%
