17. Distance to Work Johnny gets to work in 20 minutes
Marrrta [24]

Answer:

2.25 miles

Step-by-step explanation:

When driving a car time taken is 20 minutes. This is equal to 20/60 hours , 1/3 hours / 0.3 hours

When riding a bike , time taken is 45 minutes. This is 45/60 hours , 3/5 hours/ 0.75 hours

The formula for speed is : Speed = Distance covered / time taken

The statement is that the driving speed is greater than biking speed by 4.5 mph

Assuming the distance to work is x miles then;

x/ 0.3 - x/0.75 = 4.5  ------eliminate 0.3 by multiplying each term by 0.3 to get

x- 0.3/0.75 x = 1.35 -------eliminate 0.75 by multiplying each term by 0.75 to get

0.75 x - 0.3 x = 1.0125

0.45 x = 1.0125

x= 1.0125 / 0.45

x = 2.25

#2 & #3 with answer and explanation please??????
pishuonlain [190]
2) If we have 2 points K & M with their coordinates (x₁,y₁) & (x₂,y₂), the the distance of KM is given by the formula:

KM = √[(x₂-x₁)² + (y₂-y1)²] ; K(2,3) & M(5,1) (Given)
KM = √[(5-2)² + (1-3)²] ==>√(9+ 4) ==> KM = √13 (ANSWER D)

3) The coordinates are A(4,7) & B(-3,9). Follow & apply the same methodology as above:

AB =√[(x₂-x₁)² + (y₂-y1)²] ; A(4,7) & B(-3,9) (Given)

AB =√[(-3-4)² + (9-7)²] ==> AB = √[(-7)² + (2)²] ==> √(49+4) =√53 (B)

Distributive Property. Show work below.<br> 1/5(5r+10) - 3(r-2)
inessss [21]

Answer:

The answer is -2r + 8.

Step-by-step explanation:

1) Simplify 1/5(5r + 10) to 5r + 10/ 5.

\frac{5r + 10}{5}  - 3(r - 2)

2) Factor out the common term 5.

\frac{5(r + 2)}{5}  - 3(r - 2)

3) Cancle 5.

r + 2 - 3(r - 2)

4) Expand by distributing terms.

r + 2 - (3r - 6)

5) Remove parentheses.

r + 2 - 3r + 6

6) Collect like terms.

(r - 3r) + (2 + 6)

7) Simplify.

- 2r + 8

<em><u>Thus</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>for</u></em><em><u> </u></em><em><u>this</u></em><em><u> </u></em><em><u>equation</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>-2r</u></em><em><u> </u></em><em><u>+</u></em><em><u> </u></em><em><u>8</u></em>.
