Let that number be x.
"I multiply a number by four" Can be represented by 4x.
"Then I add one" means that to 4x, you added 1. So it's 4x + 1
"The answer is 33" So 4x + 1 = 33.
We need to solve for x.
4x + 1 = 33
First, subtract 1 from each side to have the variable on a side and the number on the other:
4x + 1 - 1 = 33 - 2
4x = 32
Divide both sides by 4 to get the variable x alone on a side and its value on the other side:
(4x)/4 = 32/4
x = 8
You can recheck your answer (very important):
4x = 8*4 = 32
4x + 1 = 32 + 1 = 33
The answer has been approved.
Hope this Helps! :)
The answer is 16 cents i believe
Answer:
v = 12 km/h
Step-by-step explanation:
To find how much she should increase the speed first we need to find the distance traveled:
Where:
d: is the distance traveled =?
v: is the velocity = 8 km/h
t: is the time = 15 min (9:00 to 9:15)
Now, we can find the speed:
Therefore, she should increase the speed to 12 km/h to reach the office at 9:10 am.
I hope it helps you!
Answer:
b. 10
Step-by-step explanation:
The triangles are all similar, so you have ...
hypotenuse/short side = x/4 = 25/x
Cross multiplying gives ...
x^2 = 100
x = 10 . . . . . . . take the square root
