Answer:
Step-by-step explanation:
So we have the equation:
First, distribute the 7 into the (x+8) and simplify:
Combine the like terms 7x and 8x by adding them together:
Subtract 56 from both sides to isolate the x:
Divide both sides by 15 to get x:
I don't understand the question, but I did get this:
Hope this helps!!
Answer:
1 13/28
Step-by-step explanation:
3×4/28 + 5×4/28. it 28 because the lcm of 4 and 7 is 28
21/28+20/28=41/28=1 13/28
Answer:
X= 20
Step-by-step explanation:
X+X+X+3-8 = 55 (Place Like terms together)
3x - 5 = 55 (Simplifying Like terms by adding and subtracting)
3x = 55+5 ( Move -5 towards Right hand side of equal as there is 55 which is like term of -5 and if we move any number or value from one side of equal towards other the sign of that value would change)
3x = 60
X= 60/3 ( Move 3 toward others side as there is like term of 3 which is 60 but as on Left hand side of equal sign 3 is multiplying with "X" so when we move any number or value toward other side the operation or sign of that value or number would be change, Multiply change into Divide and vice versa and Add change into subtraction and vice versa)
X= 20
1st angle - x⁰
2nd angle - (x+25)⁰
The angles are supplementary,
so
x+x+25=180
2x=155
x=77.5⁰ -1st angle
77.5+25=102.5⁰ - 2nd angle
