Can someone please check my answers.

1. Solve. –7x + 1 + 8x = x + 1

A) Identity B) No solution C) 1 D) 0

My answer: A) Identity

2.The length of one of the equal legs of an isosceles triangle is 8 cm less than 4 times the length of the base. If the perimeter is 29 cm, find the length of one of the equal legs.

A) 11 cm B) 12 cm C) 5 cm D) 4 cm

My answer: B) 12cm

3. A home purchased for $300,000 depreciated 8% over a 1-year period. What was the value of the home after at the end of the year?

A) $274,000 B) $278,000 C) $272,000 D) $276,000

My answer: D) $276,000

4. Solve. 8x - 1 - x = 7x + 1

A) No solution B) 0 C) 1 D) Identity

My answer: A) No solution

5.Elaine was charged $195 interest for 1 month on a $1000 credit card balance. What was the monthly interest rate?

A) 20.5% B) 20% C) 19% D) 19.5%

My answer: D) 19.5%

Is it just me or does #5 seem like the interest rate should be 0.195 instead of 19.5%?? Because $1000*0.195=195 and that would be a lot more reasonable than 19.5%. I don't know...

I agree with your anwser of 19.5%.

195/1000 = .195

.195 * 100 = 19.5

So it is 19.5% D is the correct answer there.

Yes, based on the information provided, your answers are correct.

For the first question, to solve the equation -7x + 1 + 8x = x + 1, you can simplify it by combining like terms. This gives x = x, which is an identity.

For the second question, you can set up an equation using the given information and solve for the length of one of the equal legs. The equation would be 2x + b = 29, where x is the length of one of the equal legs and b is the length of the base. Then you can substitute x = 4b - 8 into the equation and solve for x. The correct answer is B) 12 cm.

For the third question, you can calculate the depreciation of the home by multiplying the value of the home ($300,000) by the depreciation rate (8%). Then subtract the depreciation amount from the original value to find the value of the home after one year. The correct answer is D) $276,000.

For the fourth question, you can solve the equation 8x - 1 - x = 7x + 1 by combining like terms. This gives 7x - 1 = 7x + 1, which simplifies to -1 = 1, indicating there is no solution. So the correct answer is A) No solution.

For the fifth question, you can calculate the monthly interest rate by dividing the interest ($195) by the balance ($1000). Then multiply by 100 to convert it to a percentage. The correct answer is D) 19.5%.

Overall, your answers are correct. Great job!
