Answer:
y=7 and x=-8
Step-by-step explanation:
Isolate x in the first equation:
10x=-17-9y
x=(-17-9y)/10
Substitute into the second equation:
7*((-17-9y)/`10)+10y=14
-119/10+37y/10=14
-119+37y=140
37y=259
y=7
Putting this into the first equation, we get that x=-8

-4(y-2)=12 help please
Answer:
-2
Step-by-step explanation:
(y-2)=-(12/4)
y-2= -4
y= -4+2
y = -2
Answer:
y = -1
Step-by-step explanation:
1. -4(y - 2) = 12
2. -4y + 8 = 12
3. -4y + 8 = 12 - 8
4. -4y = 4
5. -4y/-4 = 4/-4
6. y = -1
Check your answer:
-4(y - 2) = 12
-4(-1 - 2) = 12
4 + 8 = 12 True
Ann saved 20.00 daily fir the month of July to purchase a video game costing 900.00 less 25% . How much more money does he still need?

31x20=620
675-620=55
Use the property of parallelograms to solve for the missing variable
Answer:
x = 30, y = 6
Step-by-step explanation:
Here, we want to use the property of parallelograms
mathematically, the lengths of the parallel sides are equal
This mean:
2y + 3 = y + 9
2y - y = 9-3
y = 6
To get x;
Angles that face each other are supplementary; meaning they add up to 180
Thus, we have that
4x + 2x = 180
6x = 180
x = 180/6
x = 30
2x²-24x+64=0 How do you solve my factoring this

You told your friend that you could eat 5/8 of a large pizza. If you only ate 1/2 of what you said you could eat, what fraction of a large pizza did you eat?
Answer:
5/16
Step-by-step explanation:
Given that:
Fraction of claim = 5/8
Amount actually eaten = 1/2 of claim
Amount actually eaten = 1/2 * 5/8 = 5/16
Fraction of large pizza actually eaten is 5 /16
Hence, he ate, 5/16 of large pizza

Two families went to the event. The first family bought two children's tickets and one adult ticket and paid a total of 8.2 euros. The other family bought three children's tickets and two adult tickets and paid a total of 14.1 euros. Can you tell me how much one child costs and how much one adult ticket costs?
Answer:
Step-by-step explanation:
step a system of two equations c = child ticket a = adult ticket
eq 1) 2c + 1a = 8.2 multiply by 2
eq 2) 3c + 2a = 14.1
I will multiply eq 1 times TWO and subtract eq 2 from eq 1a)
eq 1a) 4c + 2a = 16.4
eq 2) 3c + 2a = 14.1
subtract (4c - 3c) + (2a -2a) = 16.4 - 14.1
c + 0 = 2.3 euros for one child ticket
Now find the adult ticket price, plug 2.3 for c into eq 1)
eq 1) 2c + 1a = 8.2
eq 1) 2(2.3) + 1a = 8.2 solve for a
4.6 + a = 8.2 substract 4.6 from both sides
a = 8.2 - 4.6
= 3.6 euros for one adult ticket
double check using eq 2) we know c and a values
eq 2) 3c + 2a = 14.1
eq 2) 3(2.3) + 2(3.6) = 14.1
6.9 + 7.2 = 14.1
14.1 = 14.1
