Step 1: multiple the second equation by 2 so that you get -1/4 for the coefficient of y, the same as in equation 1
equation 2 multiply by 2: 1/4 x - 1/4 y=38 ..........name this equation 3
subtract equation 1 from equation 3: (1/4 x -1/2 x)=38-10
-1/4 x = 28
x=-112
plug in x=-112 in any of the equation, you will get y=-264
so the answer is A
Answer:
Part A= 315
Part B= Saturday and Sunday
Step-by-step explanation:
Answer:
7n^2
Step-by-step explanation:
Multiply 8/n by 7n/7n to get 56n/7n^2
28% of 1500 is 420.
so add it to 1500 and you’ll get 1920
