Could you help me with these four Algebra questions?

Question

1. Which of the following could represent consecutive even integers?

A) x + 1, x + 2

B) x + 1, x + 3

C) 2x, 2x + 1

2. Dwayne's garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. If the perimeter is 49 ft, how long is each side?

Which equation represents this?

A) 2x = 49

B) 2x + 4 = 49

C) 3x = 49

D) 3x + 4 = 49

3. If four times a certain number increased by 6 is equal to 94, what is the number?

If x represents the number, then which of the following equations could be used to solve the problem?

A) 4x + 6 = 94

B) 4(x + 6) = 94

C) x + 6 = 4(94)

4. The sum of three numbers is 69. If the second number is equal to the first diminished by 8, and the third number is 5 times the first. What are the numbers?

If x represents the first number, then which of the following equations could be used to solve the problem?

A) x = 6x - 8

B) 69 = 6x - 8

C) 69 = 7x - 8

Answer 1

1.B

2. D

3. A

4.C

I agree with the last post except for the last question. the calculation for 4 is as follows

x+(x-8)+5x=69. when you reduce all that you get 7x-8=69

Answer 2

1.B

2. D

3. A

4. B
