Answer:
2x = 10
Step-by-step explanation:
7 + 3x = 22
-7 -7
Subtract 7 from both sides (you are trying to get the variable alone, and to do that, you have to get every other number to 0. <em>7 - 7 = 0</em>. BUT, whatever you do, you have to do to both sides.)
3x = 15
/3 /3
Divide both sides by three to get the variable alone.
x = 5
Now, plug in the value of x to the second equation and solve.
2(5) = ? --> 10
If it’s a ratio of 3:2, it’s basically giving you two separate expressions, which are 3x and 2x. Use 8 for the smaller expression: 2x=8 and x=4. Plug in x to larger expression: 3(4)=12. Radius of larger circle is 12.
The answer would be -3.333333
Step 1: (1÷3)= 0.333333
Step 2: 3+0.333333= 3.333333
Step 3: Finally you would bring the negative sign down and the answer would be -3.333333! I hope this helps :)
