Answer:
Step-by-step explanation:12x=5x+14, 7x=14,
x=2
Answer:
x=-5
Step-by-step explanation:
4(x-5)+2=x+3 As the first step says, distribute the 4 (multiply all numbers in the parentheses by 4).
4x-20+2=x-3 Combine like terms. For example, the -20 and 2 are like terms because they are both their own numbers and not attached to a variable.
4x-18=x-3 Subtract x from each side. Now, we can get x to only one side.
<u>-x -x</u>
3x-18=-3 Add 18 to both sides.
<u>+18 +18</u>
3x=-15 Divide both sides by 3.
<u>/3 /3</u>
x=-5
I hope this helped you!! Have a great day c:
Answer:
Combine the terms with the same variable
Step-by-step explanation: so 9x-4x+9x-4x
Answer:
5) 9
6) 11 2/3
Step-by-step explanation:
Use the Pythagorean Theorem.
5) a²+5.6²=10.6²
a²+31.36=112.36
a²=81
a=√81
a=9
6) a²+4²=12.3333²
a²+16=152.11111
a²=152.11111-16
a²=136.1111
a=√136.1111=11.6666
