Assuming x is the hours each car has driven,
54x+56=52x+70
2x+56=70
2x=14
x=7
7 hours
52(7)+70
364+70
434 units (miles, yards, etc.)
Answer:
x=11.1mi
Step-by-step explanation:
<u>29.6mi </u> <u> x </u>
120 min 45 min
cross multiply and divide
120x = 45*29.6
x = 45*29.6/120
x = 11.1 mi
answer:
x = 4
y = 19
step-by-step explanation:
- we know that this is a parallelogram, so opposite sides are equal
- this is one of the properties of a parallelogram
therefore,
segment AB = segment DC <em>and</em> segment AD = segment BC
- now plug in the expressions according to what we know (& solve)
AB = DC
5x - 13 = 9x - 29
-13 = 4x - 29
16 = 4x
x = 4
AD = BC
3y - 11 = 2y + 8
y - 11 = 8
y = 19
They’re not equivalent because 18 divided by 6 is not the same as the quotient of 8 divided by 4
55
is the answer
because it's supposed to be =x
