Set up a system of equations.
d + q = 75
.1d + .25q = 14.25
Multiply the first equation by -.1 so that the "d's" will cancel.
-.1d -.1q = -7.5
.1d +.25q = 14.25
Now add the two equations together
.15q = 6.75
divide both sides by .15
q = 45
There are 45 quarters in the jar
Answer: 5g5
Step-by-step explanation:
Answer:
y=1/2x+6
Step-by-step explanation:
for the equation you start with finding the rate of change (wich is what y changes by as x 9minths) in creases by 1) and then add the Y-intercept, so it would be Y=1/2x+6
Formula:
Y=△y•x+b(y-int)
To find y intercept find what <em>y </em>is when x is 0, or in this case you know it comes out 6 feet tall, so that is what the Y int. is
The answer should be (x-4)^2+(y+2)^2=radical 26
