Ryan volunteered 34 hours

Step-by-step explanation:

Let

x ----> the number of Ryan's hours

y ----> the number of Maddie's hours

we know that

x+y=45 -----> equation A

x=3y+1 ----> equation B

substitute equation B in equation A and solve for y

$3y+1+y=45\\4y=45-1\\y=44/4\\y=11\ hours$

Find the value of x

$x=3(11)+1\\x=34\ hours$

therefore

Ryan volunteered 34 hours

The value of a collectible coin can be represented by the equation y = 2 x + 15, where x represents its age in years and y represents its total value in dollars. What is the value of the coin after 19 years? $2 $23 $38 $53

Step-by-step answer

P Answered by PhD

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

A 4300-N force from a car s engines produces an acceleration of 3.3 m/s2. What is the mass of the car? A. 4300 kg B. 1300 kg C. 14,000 kg D. 390 kg

Step-by-step answer

P Answered by PhD

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

=4300/3.3

=1303.03kg

Approximately it is aqual to 1300kg
