Fiona bought some socks that cost $4.95 for each pair and some belts that cost $6.55 each. Fiona spent $27.95 in all. Let a represent the number of pairs of socks purchased and b the number of belts purchased

Answers

The question lacks the total number of socks and belts altogether. Thsi value is necessary so that we can create another equation to solve the unknowns.

if assumed that a = b, the answer, a = b = 2.43 will not make sense since you cannot buy 43% of a pair of socks. Completely define the conditions so that the answer can be obtained.

by trial and error, 3 pair of socks and 2 belts would be a sensible answer

The answer is "C" 4.95a + 6.55b = 27.95

Answers

I think 60 - 25 = 35 because, 1/4 is equal to a quarter for example: 3/4 is 75. Think of money! Act like someone gives you 2/4’s of Quarters and how much do they give you? 50 cents.

What is the solution to the following equation? -32-8x=-7x+8(8x-4)

Answers

the answer to your question is x=0

X=0

−32−8x=−7x+8(8x−4)

−8x−32=−7x+8(8x−4)

−8x−32=−7x+64x−32

−8x−32=57−32

−8−32+32=57−32+32

−8=57

C. z = –4, 7
D. z = 8, –4

Answers

Answer: B

Heyy, this is a quadratic equation and I used the null factor law to solve this. So basically, find 2 numbers that multiply together to get 56, e.g. 8x7. But you have to make sure that the 2 numbers you choose add up to 15. Then put it in null factor law form, e.g. (z-8)(z-7)=0. Then just solve for 0. E.g. z-8=0. Which is 8. If you want, you can expand to check if it matches the original equation.. :')
