Three students, Matthew, Thompson and Amos shared #15000 in the ratio of 5:2:x respectively. If Matthew's share is 7500, calcula

jasenka [17]

Answer:

The value of x is 3.

Step-by-step explanation:

Matthew earned 7500 of 15000, which is exactly half the total amount, meaning that the fraction corresponding to his earnings is 1/2.

Rate of 5:2:x, with number 5 corresponding to Matthew, mean that his fraction of the earnings, in function of x is given by:

$\frac{5}{5 + 2 + x} = \frac{5}{7 + x}$

Both fractions are equal, so:

$\frac{5}{7 + x} = \frac{1}{2}$

Applying cross multiplication:

$7 + x = 10$

$x = 10 - 7$

$x = 3$

The value of x is 3.

Help please! I know I'm supposed to calculate how many hours she worked then multiply it by 6.75$ but I cannot get any answers t

Marcia started work at 7.32 and finished work at 3.43. In total she worked 8 hours and 11 minutes.

Convert the 11 minutes into decimal form:

11 minutes / 60 minutes in an hour = 0.18 (rounded)

Multiply her hourly rate by her hours worked:

8.18*6.75 = $55.125 (you can round this up or down).

Solve for f. 2+1.25f=10-2.75f

Harrizon [31]

f = 2

Simplify both sides of the equation 1.25f+2=−2.75f+10

Add 2.75 to each side 4f+2=10

Subtract 2 from both sides 4f=8

Divide each side by 4 f=2
