Find the solution to the system of equations. You can use the interactive graph below to find the solution. 8x + 4y = 24
-7x + 7y = 28
x=
y=​

Answers

Answer 1

Answer:

X=11y+4       y= -1/11x + 4/11

Step-by-step explanation:

Let's solve for x.

8x+4y+24−7x+7y=28

Step 1: Add -24 to both sides.

x+11y+24+−24=28+−24

x+11y=4

Step 2: Add -11y to both sides.

x+11y+−11y=4+−11y

________________________________  

 answer: x=−11y+4

_______________________________

Let's solve for y.

8x+4y+24−7x+7y=28

Step 1: Add -24 to both sides.

x+11y+24+−24=28+−24

x+11y=4

Step 2: Add -x to both sides.

x+11y+−x=4+−x

11y=−x+4

Step 3: Divide both sides by 11.

11

11y/11 = - x+4/11

y=-1/11x +4/1

____________________

Answer:  y= -1 / 11 x  + 4/11

5/n+3
5n+1/n+3

Answers

Answer:

5(n+1)/((n+1)(n+3))

5/(n+3) is a answer

Step-by-step explanation:

(n+1)/(n+1)=1

The solution is, the simplified product of the expression 5/n+1*n+1/n+3 is 5/(n+3) .

here, we have,

given that,

the expression is  5/n+1*n+1/n+3

now, we have to find the  simplified product.

as, * means the multiplication,

we get,

5/n+1*n+1/n+3

=5*(n+1)/((n+1)*(n+3))

now, we know that,

(n+1)/(n+1)=1

so, we get,

5*(n+1)/((n+1)*(n+3))

=5*1 /(n+3) *1

=5/(n+3) is a answer

An isosceles triangle has a perimeter of 28.12 centimeters. The length of the longest side is 13.08 centimeters. What could be the length of
one of the other sides of the triangle?
A. 3.92 centimeters
B. 7.52 centimeters
C. 11.26 centimeters
D. 15.04 centimeters

Answers

Answer:

7.52 cm

Step-by-step explanation:

If we subtract the longest side from the whole perimeter, we get 28.12 - 13.08 = 15.04.

So the other two sides must be equal, since the triangle is isosceles.

That means 15.04 must be divided evenly betweem two sides.

15.04/2 = 7.52

So the 3 sides are 13.08 cm, 7.52 cm, and 7.52 cm.

You check the answer by adding all 3 sides together and we do indeed get the perimeter, 28.12 cm.

Step-by-step explanation:

Percent error=(Estimated value-Actual value/ Actual value) × 100

Estimated value = amount of cookies Payton thought the mix could make = 36

Actual Value= Amount of cookies made= 28

Percent error= (36- 28)/ 28 x 100

Answer:

p + 10

Step-by-step explanation:

We have an expression

"10 more than the number p"

How will you write the phrase?

The expression "10 more than the number p" shows that whatever amount p is, the total will always be 10 more of value than p. Therefore some type of adding is supposed to be here. Since this unknown value of a number will always be 10 more than p, we can come up to assume that p will be added by 10.
