Answer:
r = P -t -s
Step-by-step explanation:
This is a one-step linear equation in r. Subtract the terms that don't contain r:
P = r + t + s . . . . . . . . . . given
The terms on the right that don't include r are (t+s). We want to subtract that to get r by itself.
P -(t+s) = r +(t+s) -(t+s) . . . subtract (t+s)
P -t -s = r . . . . . . . . . . . . . . simplify
r = P - t - s
Answer:
each side is 17.2 feet
Step-by-step explanation:
a heptagon has 7 sides. 120.4 divided by 7 is 17.2. tell me if i am wrong. otherwise, hope this helps :)
A = (1/2)(x)(y)
Let x = diagonal 1
Let y = diagonal 2
The product of xy = 144.
This means that x = 12 and y = 12.
So, 12 • 12 = 144
Each diagonal is 12 feet.
Prove:
72 feet = (1/2)(12)(12) feet
72 feet = (1/2)(144) feet
72 feet = 72 feet
Use distributive property.
4(m - 2) = 24
Add 8 on both sides to leave the variable on one side.
4m - 8 = 24
+8 +8
Divide 4 on both sides.
4m = 32
---- ------
4 4
You'll get a solution of 8.
m = 8
Check:
4(8 - 2) = 24
32 - 8 = 24
24 = 24
Answer:
(3)x+(3)
Step-by-step explanation:
- the slope is 3 because rise/run and rise is 3 and run is 1 from point (-2,0) and (0,3)
- the y intercept is 3
- plug it in the formula which is y=mx+b (m is slope and b is y intercept
