The larger number is 2x + 7. The smaller number is x.

2x + 7 + × = 43

3x + 7 = 43

3x +7 -7 = 43 -7

3x = 36

3x/3 = 36/3

× = 12

checking...

2 (12) + 7 + 12 = 43

vovangra [49]

Answer: 8200 miles

Step-by-step explanation:

Based on the question, since she wants to go for five round trips, her first round trip is fixed at 3400 and she will have 4 more additional trips. This can them be calculated as:

= 3400 + 1200x

x = additional trips = 4

We then put the value of x into the equation

= 3400 + 1200x

= 3400 + 1200(4)

= 3400 + 4800

= 8200

She'll have 8200 mile after 5 round trips

The product of three consecutive numbers is 21,924. What is the smallest number out these numbers?
Natasha_Volkova [10]

Answer:

27

Step-by-step explanation:

Let the middle number be x.

(x - 1)(x)(x + 1) = 21,924

You can solve that equation, or you can use logic.

The 3 numbers are going to be close to the cubic root of 21,924.

cubic root of 21,924 = 27.988 or approx 28.

Try 27, 28, 29

27 * 28 * 29 = 21,924

Answer: 27
