So since they are similar
AC/BC=CD/CE
so
(66-x)/30=(x+4)/5
times both sides by 5
(66-x)/6=x+4
times both sides by 6
66-x=6(x+4)
distribute
66-x=6x+24
add x to both sides
66=7x+24
minus 24 from both sides
42=7x
divide both sides by 7
6=x
x=6 units
Answer:
3(27) = 3(25 + 2) = TURE
Step-by-step explanation:
Left side: Use long multiplication:
| | 3
× | 2 | 7
Multiply 7 by the digit in the top row:
| | 3
× | 2 | 7
| 2 | 1
Multiply 2 by the digit in the top row:
| | 3
× | 2 | 7
| 2 | 1
| 6 | 0
Add:
Answer: 81
Right Hand: Simplify the following:
3 (25 + 2)
Hint: | Evaluate 25 + 2.
25 + 2 = 27:
3×27
Hint: | Multiply 3 and 27 together.
3×27 = 81:
Answer: 81
650 is your answer because you have ti take away the zeros
