The like terms are the variables which are being multiplied by different coefficients.
In this case, the like terms are:
3a, a
----------
Now, 3a + a = 4a
----------
Therefore:
3a + a + 5
= 4a + 5

Answer:
dollars per hour
Step-by-step explanation:
If m is the slope, the units of m can be found by considering the units of x and y.
y is in dollars
x is in hours
Then from the point of view of units, we have ...
dollars = m × hours
m = dollars/hours
The slope in the equation is the rental charge in dollars per hour.
Answer:
Volume = 80 in³
Step-by-step explanation:
The formula for volume of a pyramid is;
v=(A*h)/3
where
A=Area of triangular base
h=height of pyramid
Finding area of triangular base;
A=1/2*b*h
A=1/2*10*6=30 in²
Finding the volume
v=(A*h)/3
v=(30*8)/3=80 in³
In oder to count the percentage you have to divide the number of instances over the number of possible instances and multiply by 100% (100 % is also 1).
4/50*100%= 2/25*100%=2*4%=8 %.
So the answer is 8 %.
Global warming is an example because the Earth is moving closer to the sun, so the earth is slowly getting hotter.
