Matthew is shopping for shoes and socks. he has $75.00 to spend. the shoes he likes cost $28.00, and the socks cost 4.00. write and inequality for this situation. can matthew buy 2 pairs of shoes and 5 pairs of socks?

Step-by-step explanation:

First, you would want to use the property of multiplication and multiply

28.00 by 2 and that will give you 56.

So it will cost 56 dollars to get 2 pairs of shoes.

Then, you would also want to use the property of multiplication again and multiply 4 by 5 and that will give me 20.

So it will cost Matthew 20 dollars to 5 paris of socks.

Finally, we would use the property of addition and add 20 and 56 and that will give you 76 dollars so 2 pairs of shoes and 5 pairs of socks will cost 76 dollars.

In conclusion, no Matthew can not buy 2 pairs of shoes and 5 pairs of socks.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
