Answer

7,0

Step-by-step explanation:

Substitute -6y+7 into problem one where the x is

distribute the 2 and subtract the 9 y and you will get

-21y+14=14

subtract 14 from both sides and it will be -21y=0 so y will be 0

substitute the 0 into equation 2 and find x=7

1.) 2(-6y+7)-9y=14
2.) -12y+14-9y= 14
3.) -21y + 14 = 14
4.) -21y = 0
5.) -21y/-21 = 0/-21
y = 0
6.) 2x-9(0) =14
7.) 2x=14
8.) 2x/2 = 14/2
x=7
so, your answer is (7,0)

Solve the literal equation for y.<br><br> 2x+5y = 3y+8
ozzi

Answer:

y = -x +4

Step-by-step explanation:

2x+5y = 3y+8

Subtract 3y from each side

2x+5y-3y = 3y-3y+8

2x+2y = 8

Subtract 2x from each side

2x+2y -2x = -2x+8

2y = -2x+8

Divide by 2

2y/2 = -2x/2 +8/2

y = -x +4

Total cost for cookie and lemonade is 1.80. If lemonade costs 1.00 more than the cookie, how much was the lemonade?
Ray Of Light [21]

Answer:

The lemonade costs 1.4.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x is the cost of a cookie.

y is the cost of a lemonade.

Total cost for cookie and lemonade is 1.80.

This means that x + y = 1.8.

As we want y, we have that x = 1.8 - y

Lemonade costs 1.00 more than the cookie?

This means that:

y = x + 1

So

y = 1.8 - y + 1

2y = 2.8

y = \frac{2.8}{2}

y = 1.4

The lemonade costs 1.4.

What is the missing side length in the triangle?<br><br> plsss someone help!!
UkoKoshka [18]

Answer:

The measure of the missing side length = 45

Step-by-step explanation:

Pythagorean Theorem states: A² + B² = C²

28² + B² = 53²

784 + B² = 2809

B² = 2809 - 784

B² = 2025

B = \sqrt{2025}

B = 45

Therefore the measure of the missing side length = 45

Hope this helps!
