50mph, 60 minutes, half both 25 and 30
A-B should be 30 minutes
B-C should probably be 20-25 personally I'd go with 25
so 55?
-5 (2u+10)=2 (u_7) apply distributive property
-10u-50=2u-14 collect like terms
-10u-2u=50-14 when you move the number to the other side sign change
-12u =36 to get rid of 12 divide 12 on both sides
-12u/-12= 36/-12
U= -3
Answer:

Step-by-step explanation:
Given expression,

By distributive property,

Again by distributive property,

Combining like terms,

Which is required product.
Multiply 36 and 0.25
36 x 0.25 = 9
Answer: 9
