Answer:
there is no solution
Step-by-step explanation:
Expand.
15x+35+2x=7x+10x-4515x+35+2x=7x+10x−45
2 Simplify 15x+35+2x15x+35+2x to 17x+3517x+35.
17x+35=7x+10x-4517x+35=7x+10x−45
3 Simplify 7x+10x-457x+10x−45 to 17x-4517x−45.
17x+35=17x-4517x+35=17x−45
4 Cancel 17x17x on both sides.
35=-4535=−45
5 Since 35=-4535=−45 is false, there is no solution.

Answer:
682
Step-by-step explanation:
620, percentage decreased by - 10% (percent) of its value = 682
An inscribed angle (BAC) is one half the angle of a central angle (BOC) that intercepts the same arc. Therefore, BAC = 34 degrees.
Answer:
4
Step-by-step explanation:
25% is the same as 1/4.
1 is 1/4 of what number?

You can also answer it with an equation.
Let x = the number you are looking for.
1 is 25% of x can be written as the following equation.
25% of x = 1
0.25x = 1
Multiply both sides by 4.
x = 4
