Answer:
13. $55.50 - $29.25 = $26.25
$26.25 ÷ 5 = $5.25
C. 29.25 + 5t = 55.5; t = $5.25
11. $500 - $119.75 = $380.25
$380.25 ÷ $2.25 = 169
C. 119.75 + 2.25p < 500; p < 169
16. 8 + 7 + 3 + 42 = 60
42/60 = 0.7
540 × 0.7 = 378
B. About 380 students take the bus to school
17. 25% increase = 125% = 1.25
280 × 1.25 = 350
350 × 9 = 3,150
3,150 - 3,114 = 36
A. He will break the record by 36 yards
19. 25,000 - 17,500 = 7,500
7,500 ÷ 2,500 = 3
C. Greater than 3
22. 17.55 ÷ 5 = 3.51
A. 3.51 feet
23. A negative number divided by a positive number is still negative, so fractions will be equivalent regardless of the negative symbol being with the numerator or denominator.
B. 9/-16
A direct variation has a constant slope, i.e. (y/x)= constant.
Both of the given two points give a slope of (y/x)=14/2=28/4=7, so the equation of the function is
y/x=7, or simply
y=7x
Answer:
I believe there are four terms in this expression.
Answer:
the equation would be y=1/2x-9/2
