Answer:
Step-by-step explanation:
so 7 in is the height so we already have found our height.
to find the base in the inside of the rectangle they have a value of 12.5 ST is 12.5 and TS is 12.5 if u add them up you will get 25
so area for rectangle is
A=wl
so 7x25=175 so our answer is
a=175
60 minutes per hour
so 1260 x 60 = 75,600 beats per hour
75,600 * 24 = 1,814,400 beats in 24 hours
We need to solve for x. Let's try problem b:

Let us first combine line terms. 3x and -x as well as 1 and -7 can be combined. Let's do that:

Since this is true, your answer would be:
All real numbers
------------------------------------------------------------------
Let's solve for problem c:

Let's isolate x, so subtract 1 from both sides:

Since x can't have a coefficient, divide both sides by 3:


So, only the value of 14 would make this equation true.
------------------------------------------------------------------
Let's try problem d:

Let's get our whole numbers on the right side. Add 1 to both sides:

Subtract 4x from the right side on both sides:

Since this is not true, your answer would be:
No solution
