.70 * x = 9.1
.70/.70 * x = 9.1/.70
x = 13
multiply 6 x 6 to get 36 and 7 x 11 to get 77.
6/7 x 6/11 = 36/77
Answer:

Step-by-step explanation:
Slope Formula: 
Simply plug in the 2 coordinates into the slope formula to find slope <em>m</em>:



Answer:
C. 56°
Step-by-step explanation:
An isosceles triangle has two sides that are equal. ∆ABC has two equal sides. Thus, the angles opposite the two sides of an isosceles triangle are also congruent to each other.
<C and <A are congruent to each other.
m<A = 56°, therefore,
m<C = 56°
Answer:
Step-by-step explanation:
From the attachment, we can see that
<EBF = 33°
<EBD = 33°
<FED = 114°
<FBD = 66°
Part 2
The value of y is either of 70 or -80. But then, we all know that speed can not be negative, so the speed was 70 km/h
The return speed is y + 10 = 70 + 10 = 80 km/h
Total time = 350/70 + 350/(70+10)
Total time = 5 + 4.375
Total time = 9.375 hr
