There are a total of 4 quarters and 16 nickels.
Answer:
see the explanation
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x ----> the time in seconds
y ---> the distance in meters
In this problem we have a proportional relationship between the variables x and y
Find the constant of proportionality k

For x=2, y=25 ---> 
For x=4, y=50 ---> 
For x=6, y=75 ---> 
For x=8, y=100 ---> 
so
The value of k is 
In this problem the value of k or slope represent the speed of the train
The linear equation is equal to
or
45 minutes is equal to 1.5 times 30:
1.5*30=45
so she will also read 22*1.5 pages, which is 22+11=33
so she will read 33 pages
Answer:
Step-by-step explanation:
64
because the small triangle at the top is isoscel and has the base angles BDE and BED = (180 -48)/2 =66
angle BDE is congruent to DAC = 66, because 2 || BE and AC are cut by transversal BA
angle ADC = 180 -50 -66 = 64
Answer:
They have the same x value.
