X=-17/8
10x + 10 = 2x - 7
8x = -17
x = -17/8
Answer:
so yes
Step-by-step explanation:
If you can divide two numbers without a remainder, then the first number is divisible by the second.
For example, 12 is divisible by 2.
12÷2=6
But 12 is not divisible by 5. When you divide 12 by 5, you get a remainder.
12÷5=2 R2
Answer:
I think 3.
Step-by-step explanation:
You make a right triangle, an isosceles, and a scalene. You can't make an equilateral, because those sidelengths are not the same size.
Answer:
fg(x) = √143x+121
Step-by-step explanation:
in such function we go right to left
given = f(x) = √11x and g(x) = 13x + 11
fg(x) =
f( 13x + 11 )
√11( 13x + 11 )
√143x+121
therefore found fg(x) = √143x+121
Answer:
x=1
Step-by-step explanation:
77+9x=18x+68
Subtract 9x from each side
77+9x-9x=18x-9x+68
77 = 9x+68
Subtract 68 from each side
77-68 = 9x
9 = 9x
Divide by 9
9/9 =9x/9
1 =x
