Answer:
x=2
Step-by-step explanation:
6x+7x−3x=13+7
10x=20
x=20/10
x=2
Answer:
5 4/9
Step-by-step explanation:
9 * 5 = 45
49 - 45 = 4
Answer:
C.
Steps:
Using points (1,0) and (0,3), you can find the slope.
3 - 0 = 3
1 - 0 = 1
3/1 = 3
To get the solution we are looking for we need to point out what we know.
1. We assume that 55 is 100% because its the output value of the task.
2. We assume that the x is the value we are looking for.
3. If 100% = 55 so we can write it down as 100%=55
4. We know that x% = 44 of the output value so we can write it as x%=44.
5. Now we have two simple equations: 1) 100%=55 2) x%=44 where left sides of both of them have the same units and both right sides have the same units so we can do something like that 100%/x%=55/44.
6. Now we just have to solve the simple equation and we will get the answer.
7. Solution for 44 is what percent of 55 100%/x%=55/44 (100/x)*x=(55/44)*x we multiply both sides of the equation by x 100= 1.25*x we divide both sides of the equation by (1.25) to get x 100/1.25=x 80=x now we have: 44 is 80% of 55!
Quick answer = 44 is 80% of 55
Hope this helps! ;D
