riadik2000 [5.3K]

Answer:30km/hr

Step-by-step explanation:

Total distance=294km

Speed=s

Distance=d

Time=t

First drive:

t=5

d=s x t

d=s x 5

d=5s

Second drive:

t=4

Speed is 6km/h greater than the first speed

The new speed= s+6

d=4(s+6)

Total distance=294

5s + 4(s + 6)=294

5s + 4s + 24=294

Collect like terms

5s + 4s=294 - 24

9s=270

Divide both sides by 9

9s/9=270/9

s=30

First speed=30km/hr

I NEED HELP WITH THIS AND U GOTTA EXPLAIN HOW U GOT THE ANSWER q2
Fantom [35]

Answer:

27 degrees

Step-by-step explanation:

5t - 13 = 3t + 3

subtract 3t on both sides

2t - 13 = 3

add 13 to both sides

2t = 16

divide by 2 on both sides

t = 8 degrees

Now, plug in 8 to the measure of x

5(8) - 13 = 27
