Answer:

x=48

Step-by-step explanation:

What number out of 75 gives you 64%

What number out of 75 gives you 64 out of 100

x                    64

------------ = -----------

75                 100

Using cross product

100x = 64*75

100x =4800

Divide each side by 100

100x/100 = 4800/100

x=48

Write the expression fourteen added to the product of seven and a number
victus00 [196]

Answer:

(7×x)+14

Step-by-step explanation: Because we have 14 added to something, we will need a + to whatever we are adding to. The product of 7 and a number is 7×x because product is the number you get after multiplication. So we get 7×x+14. You dont need parenthesis

Hope this helps!

Adam, Barry, and Charles visited a small farmers market last Saturday. Adam purchased 3 dozen eggs, 1 wheel of cheese, and 5 pou
evablogger [386]

Answer:

A pound of potato costs $3.10

A dozen egg costs $5.5

A wheel of cheese costs $6.25

Step-by-step explanation:

Represent

- a dozen egg with D

- a wheel of cheese with W

- a pound of potato with P

For Adam:

3D + W + 5P = 38.25 ---- (1)

For Barry:

D + 10P = 36.50 ---- (2)

For Charles:

2D + 2P = 17.20 ---- (3)

Make D the subject in (2)

D = 36.50 - 10P

Substitute 36.50 - 10P for D in (3)

2(36.50 - 10P) + 2P = 17.20

73 - 20P + 2P = 17.20

73 - 18P= 17.20

Collect Like Terms

- 18P= 17.20 - 73

- 18P= -55.8

18P= 55.8

Solve for P

P = 55.8/18

P = 3.1

Substitute 3.1 for P in D = 36.50 - 10P

D=36.50 - 10 * 3.1

D=36.50 - 31

D=5.5

Substitute 3.1 for P and 5.5 for D in 3D + W + 5P = 38.25

3(5.5) + W + 5(3.1) = 38.25

16.5 + W + 15.5 = 38.25

Solve for W

W = 38.25 - 16.5 - 15.5

W = 6.25
