Let x be the number Henry is thinking of.
The number is doubled and got an answer of 4.
That means:
2 · x = 4
or
2x = 4
This is the equation when Henry doubled the number and got 4 as an answer.
Solve it by dividing both sides by 2.
2x ÷ 2 = 4 ÷ 2
x = 2
The original number Henry was thinking was 2.
Cheers!
Answer:
-1 /24
Step-by-step explanation:
-7/8 - (-5/6)
Subtracting a negative is like adding
-7/8 + 5/6
Get a common denominator
-7/8 * 6/6 + 5/6 *8/8
-42/48 + 40/46
-2/48
-1/24
THe scale factor = 5/2 = 2.5
So the first statement is false
and the second statement is True
13.) To solve, you make and equation for each problem, then you make them equal each other : 50h+75=65h. You have to have both variables in each side so you subtract 50h from both sides and are left with 75=15h. Then you just solve for h. h=5
