Answer:
Step-by-step explanation:
3(10 – 4x) + 6 = 12
first you need to use the distributive property
30 – 12x + 6 = 12
then subtract 6 from each side
30 – 12x = 6
then subtract 30 from each side
– 12x = -24
divide both sides by negative 12
x = 2
Answer:
CBA = DEA
Step-by-step explanation:
Theyre the only right angles listed.
Answer:
x = 78 /5
Step-by-step explanation:
5(x+4)=12-40-7x
Subtract the numbers from the left side which will equal -25-7x
Then... Distribute the -5 to x and 4 making the equation on the left
-5x -20
In all your equation should look like this
-5x -20 = -25 -7x
Then add 7x to the right side and add 20 to the left making the equation
-5x + 7x = -28 + 20
The add up the terms on each side...
2x = -8
Then divide the 2 to the left side...
Overall:
x= -4
Answer:
there is not enough information to solve
Step-by-step explanation:
You need two ordered pairs to calculate the average rate of change.
Let's say the value of the function at n = 1 is a, and the value of the function at n = 3 is b, then the average rate of change from n = 1 to n = 3 is
(b - a)/(3 - 1) = (b - a)/2
Answer:
11/125
Step-by-step explanation:
0.088
= 88 x 0.001
= 88 x (1/1000)
= 88/1000 (divide top and bottom by 8)
= 11/125 (simplest form)
