4x - 5y = -15
y = -3x + 22
Plug in your y= equation into the y variable in the other equation
4x - 5 (y) = -15
^^
y = (-3x + 22) = -15
4x - 5 (-3x + 22) = -15
Distribute
4x + 15x - 110 = -15
Combine like terms and add 110 over to -15
19x = 95
Then, divide the whole equation by 19
x = 5
Then, plug in your x into your y= equation
y = -3 (5) + 22
y = -15 + 22
y = 7
<em><u>x = 5</u></em>
<em><u>y = 7</u></em>
<em><u>(5, 7)</u></em>
Answer:
(10,51)
Step-by-step explanation:
Take the average of 3 (x1) and 17(x2). This will be your new x-coordinate.
Then take the average of 21 (y1) and 81 (y2)
(3+17)/2 = 10
(21+81)/2 = 51
Answer:
A
Step-by-step explanation:
A. 3 x 18 = 54

C. 9 x 24 = 144
D. 18 x 33 = 594
Answer:
Multiply the number of plays by the number of yards lost in a play. But to "get it" you need to also know how many yards were lost in a play, which was not stated in the problem.
Step-by-step explanation:
i.e 3*6=18 //////
so 5*3=15 incase
The answer is B because if there are 30 total and 12 are on 1 shelf, then 30-12=18
