Each truck weighs five tons. 

1st truck: n 
2nd truck: n + 2
3rd truck: n + 4
4th truck: n + 6 

n + n + 2 + n + 4 + n + 6 = 32 
4n + 12 = 32 
      - 12   - 12
--------------------
4n = 20 
----  ------
 4      4

n = 5

Martin is paid an hourly rate of d dollars per hour for the first 40 hours he works per week. He is paid one-and-a-half times hi
Nat2105 [25]

Answer:

40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

Step-by-step explanation:

Given that:

Hourly rate = d

Earning to first 40 hours = 40d

Earning of more than 40 hours = 1.5d

Amount paid per week = $770

Hours worked = 50 hours

first 40 hours + 10 hours = total earned

40d + 10(1.5d) = 770

Hence,

40d + 10(1.5d) = 770 can be used to determine Martin's hourly pay.

The smaller triangle was dilated to form the larger triangle. What is the value of x?
strojnjashka [21]

Answer:

The value of x is 14

Step-by-step explanation:

The value of x is 14 because the smaller triangle was dilated by 3 to get the bigger triangle. I figured this out because

9 ÷ 3 = 3

so this would mean that 5 was dilated by 3 also. So to figure this out, it would be

5 × 3 = 15

1 of that 15 is already there.

So this means that

15-1=14

A=14

I hope this helps you.

Petra jogs 5 miles in 40 minutes. At this rate, how long would it take her to jog 7 miles?
Wittaler [7]
(40 min)/(5 mi) = (time)/(7 mi) . . . . . the rates are the same
(7/5)*(40 min) = time = 56 min

At the same rate, it would take Petra 56 minutes to jog 7 miles.
