Answer:

x=-4,   y=7

Step-by-step explanation:

-5x-10y=-50...(1)

Multiply both sides by -1:

5x+10y=50

5x=50-10y

x=(50-10y)/5

Substitute <u>x=(50-10y)/5</u> into second given eqaution:

10(50-10y)/5+8y=16

Cancel out common factor 5:

2(50-10y)+8y=16

100-20y+8y=16

-12y=16-100

-12y=-84

y=84/12

y=7

Substitute y=7 into equation (1)

-5x-10(7)=-50

-5x-70=-50

-5x=-50+70

-5x=20

x=-20/5

x=-4

Deffense [45]

Answer:

6

Step-by-step explanation:

Ok, so all we have to do is multiply 8 * 3/4, because each child needs 3/4 of the sandwich, and there are 8 of them. The easiest (My opinion) way to do this is by turning 8 into a fraction. Turning whole numbers into fractions is really simple, just slap a /1 under them to make them a fraction. And so, our fraction is 8/1. Now, all we have to do is multiply the top part of the fraction, and then the bottom part of the fraction. So, 8 * 3 = 24, and 1 * 4 = 4. So, just put 24/4 as an answer. But, wait! We have to simplify it! 24 divided by 4 is 6, so 6 is our final answer.

Miguel wants to wallpaper the back wall of his bedroom. the wall is in the shape of a rectangle. its length is 13 feet and its w
Bingel [31]
First of all lets find the area of the rectangle.
13 ft × 12 ft = 156 square feet.
Now lets find the price which is $8 / square foot. Using proportions we get:
$8/sq ft × 156 sq ft. Simplifying we get
$8 × 156 = $1248.
The wallpaper will cost $1248

Solve:<br> -3/4+p=1/2<br> Thank you so much!
shepuryov [24]

-3 / 4 + p = 1/2

LCD 4 and 2 = 4

Multiply by LCD = 4

p. (4)- 3/4 .( 4 ) = 1/2.(4)

4 p - 3 = 2

Add 3 to both sides:

4 p - 3 + 3 = 2 + 3

4 p = 5

Divide both sides by 4 :

4p / 4 =  5 /4

p = 5/4

Find the value of x when the area of a triangle is 22 in2 and has a base of 3x-1 and height of x.
Virty [35]
The formula for the area of a triangle is (1/2)bh = A
when we plug in the numbers, we get (1/2)(3x-1)x = A
using the distributive property we get (1.5x - .5)x = A
Then its 1.5x^2 - .5x = A
then if we factor out 0.5x we get 0.5x(3x-1) = A
then with the zero product property, 0.5x can equal 0 and x would need to equal 0.
if 3x-1 = 0 , then 3x = 1 then x = 1/3. so our answer would be 1/3 I'm pretty sure because a length cannot be 0
