Let q represent the number of quarters. Then 20-q is the number of dimes. The money total is

... 25q +10(20-q) = 335

... 15q +200 = 335

... 15q = 135

... q = 135/15 = 9

The person has 9 quarters.

A Walmart truck driver estimates that it will take him 12 hours to drive 1152 km. After 5 hours, he has driven 520 km.

san4es73 [151]

(a) He would drive 96 km in an hour because 1152 divided by 12 is 96

(b) He is technically on schedule because he is driving 104 km per hour, instead of 96, so if he keeps driving at the same rate, he should get there in under 12 hours

In the figure, GK bisects FGH

bija089 [108]

Answer:

$w = 7$

Step-by-step explanation:

Given:

m<FGK = (7w + 3)°

m<FGH = 104°

angle bisector of <FGH = GK

Required:

Value of w

SOLUTION:

Since GK bisects angle FGH, it divides the angle into two equal parts. Therefore, the following equation can be generated to find the value of w:

m<FGH = 2*m<FGK

$104 = 2*(7w + 3)$ (substitution)

Divide both sides by 2

$\frac{104}{2} = \frac{2*(7w + 3)}{2}$

$52 = 7w + 3$

Subtract 3 from each side

$52 - 3 = 7w + 3 - 3$

$49 = 7w$

Divide both sides by 7

$\frac{49}{7} = \frac{7w}{7}$

$7 = w$

$w = 7$
