A collection of 77 quarters and dimes is worth $12.50. How many quarters are in the collection? PLS HELP ILL GIVE YOU BRAINLEST
mrs_skeptik [129]

Answer:

32

Step-by-step explanation:

77 quarters and dimes

q + d = 77

subtract q from both sides

d = 77 - q

---------------------------

A collection of  quarters and dimes is worth $12.50 (1250 cents)

25q + 10d = 1250

substitute for d

25q + 10(77 - q) = 1250

distribute

25q + 770 - 10q = 1250

Combine like terms

15q + 770 = 1250

subtract 770 from both sides

15q = 480

divide both sides by 15

q = 32

PLEASE HEP ME QUICK!!!!: Tom travels between the two mile markers shown and then finds his average speed in miles per hour. Sele
slega [8]

Answer:

speed=\frac{195\ miles}{3\ hours}

3\ hours=\frac{195\ miles}{speed}

3\ hours*(speed)=195\ miles

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the distance in miles

y ----> the time in hours

speed=\frac{x}{y}

we have

The distance is equal to subtract 35 miles from 230 miles

x=230-35=195\ miles

The time is equal to subtract 1:30 pm from 4:30 pm

y=4:30\ pm-1:30\ pm=3\ hours

substitute in the formula of speed

speed=\frac{195\ miles}{3\ hours}

<em>Isolate 3 hours</em>

3\ hours=\frac{195\ miles}{speed}

<em>Isolate 195 miles</em>

195\ miles=3\ hours*(speed)
