Answer:
x=23.5
Step-by-step explanation:
90=25-x/2+18
combine like terms
90=43-x/2
subtract 43 from both sides
47= -×/2
47/2= 23.5
x=23.5
or
90-25= 65
65-18=47
47/2=23.5
Tommy ran 7 miles today for his track meet
The smaller number is 63 I think.
I think this because 150/2 is 75
75-12=63
the small number would be 63
the larger number just in case u need it btw is 87 I think
hope this helps
Answer:
The 1st one is y = 11.
The 2nd one is y = 5.
The 3rd one is v = -5.
The 4th one is y = 9.
Step-by-step explanation:
1) -38 = 7y + 17 - 12y
-38 = -5y + 17
-55 = -5y
11 = y
2) 5y + 6 - 12y = -29
-7y + 6 = -29
-7y = -35
y = 5
3) -12v - 9 + 7v = 26
-5v - 9 = 26
-5v = 35
v = -5
4) -5y + 2(y + 2) = -5
-5y + 4y + 4 = -5
-y + 4 = -5
-y = -9
y = 9
