−12x−5y=40 12x−11y=88 ​ x= y=

Mathematics

Add the two equations and use the elimination method. The x term will "cancel out" to be able to solve for the y term.

STEP 1
−12x−5y=40
12x−11y=88 ​
x terms "cancels out"; add y terms

-16y= 128
divide both sides by -16

y= -8


STEP 2
substitute y value into either original equation

12x−11y=88 ​

12x - 11(-8)= 88

12x + 88= 88
subtract 88 from both sides

12x= 0
divide both sides by 12; 0 divided by any number is 0

x= 0


ANSWER: x= 0; y= -8

Hope this helps! :)

To make banana bread, Colin uses 3/4 of a cup of brown for every 2 cups of flour. How much brown sugar should Colin use to make
Lelechka [254]

\frac{3}{8} cups of brown sugar needed for only 1 cup of flour

<em><u>Solution:</u></em>

To make banana bread, Colin uses \frac{3}{4} of a cup of brown for every 2 cups of flour

To find: Amount of brown sugar should Colin use to make a small batch with only 1 cup of flour

Let "x" be the amount of brown sugar needed for only 1 cup of flour

From given information,

\text{ 2 cups of flour } = \frac{3}{4} \text{ cup of brown sugar }

\text{1 cup of flour } = \text{ x cup of brown sugar }

This forms a proportion and we can solve the sum by cross multiplying

1 \times \frac{3}{4} = 2 \times x\\\\x = \frac{3}{8}

Thus \frac{3}{8} cups of brown sugar needed for only 1 cup of flour

What is the area of this polygon?<br><br><br><br> Enter your answer in the box.<br><br><br> units²
Cloud [144]

To find the area of the given polygon, first we will join P and S .

So we have two figures here, a rectangle GPST, and a triangle , PES .

Area of rectangle is length times width .

For the given rectangle, area is GP times PS .

GP= 2-(-3) = 2+3 =5 \\ PS = 4-(-3) = 4+3=7 \\ Area = 5* 7= 35 square \ units

And for triangle , area is half of the product of height and base.

For the given triangle,

Height = 4-2=2 \\ base=4-(-3)=7 \\ Area=(1/2)2*7 = 7 \ square \ units

Total area of the polygon is the sum of areas of rectangle and triangle , that is

Total \ area = 35+7 = 42 \ square \ units

A couple wants to install a square mirror that has an area of 500 square inches.To the nearest tenth of an inch what length of w
Marizza181 [45]

A couple wanted to install a square mirror that has:

Area of the mirror = 500 square inches.

x = nearest tenth of an inch , length of wood needed

s = sides of square


Area = s2

500 (area) = s2  | √

x = √500

=> √ 5 x 100

=> √ 5 x √100

=> 10 √ 5

=> approximately 22.4


Since we’re looking for the nearest tenth of decimal place value, the answer is approximately 22.4
