Answer:
180/7 or 25 5/7
Step-by-step explanation:
20/3 * 27/7
cross multiply 3 and 27, 20/1 * 9/7 is left. Then, cannot simplify anymore.
So the answer come out.
180/7 or 25 5/7
Answer: Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*x+2*x+1-(2*x-x+21)=0
Step by step solution :
STEP
1
:
Pulling out like terms
1.1 Pull out like factors :
5x - 20 = 5 • (x - 4)
Equation at the end of step
1
:
STEP
2
:
Equations which are never true:
2.1 Solve : 5 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : x-4 = 0
Add 4 to both sides of the equation :
x = 4
One solution was found :
x = 4
C/-7+3.2=2.7
Step 1) Add 7 to both sides because what you do to one side you must do to the other
C/<u>-7</u>+3.2=<u>2.7</u>
<u> +7 +7
</u> C/+3.2=9.7
Step 2) Subtract 3.2 from both side
C/<u>+3.2</u>=<u>9.7
</u> <u> -3.2 -3.2
</u> C/=6.5
Your answer is C=6.5<u>
</u>
Answer:
A, Yes
Step-by-step explanation:
Your first answer is A because Multiply /divide both sides by the same non zero constant . Second, answer is Yes .
Hope this helps;)
