Answer:
10 + 2y
Step-by-step explanation:
2(5+y)
Distribute
10 + 2y
I believe that the answer would be 2.5
SOLVING WITH THESE VALUES:
x=2
y=3
——————————————————
The answer is 1,729 when x=2 and y=3
Work is in the pictures below :)
<em><u>Picture 1</u></em>: Solved where x=2 and y=3
<em><u>Picture 2</u></em>: Solved without plugging in values for x and y
I think -3; If the final par was -8, you would subtract (-4 + 2), you would get -6. Then you just divide it in half because it said he scored the same in rounds 3 and 4, leaving you with -3.
Answer:
a = 15
34.8 + b = 54.6
Step-by-step explanation:
First one:
5a - 10b = 45 (b = 3)
5a - 10(3) = 45
5a - 30 = 45
5a = 75
a = 15
Second one
b + a + 3a = 54.6
b + 4a = 54.6 ( a = 8.7)
b + 4(8.7) = 54.6
b + 34.8 = 54.6
34.8 + b = 54.6
