Answer:
451.5
Step-by-step explanation:
I'm rusted on the mathematics
1.)
The term (2+8) is the amount of fabric Ali bought. You know this because in the problem, it says that she buys “2 white pieces and 8 blue pieces”
2.)
The terms of the equation are
k and 2f
These are the terms because they are separated by the addition sign
3.) $36
You would first find rate per sand which. To find this, you would do:
9/2
This will give you
4.5. Now, you multiply that by 4. That gives you 36.
4.) The skateboard costs 150
How?
30 is 20% of the price. 20x5=100. So, to find the total amount, you would multiply 30 by 150.
5.) About 50 miles an hour.
You always put distance over time. If you do:
400/8
You get the average rate of 50
6.) 5n
How?
Well, there are five cents in every nickel. So, to find out how many pennies, you would multiply the amount of nickels by 5.
Have a good night :)
I think the answer would be the last one. a cylinder with radius 4 units.
Answer:
Step-by-step explanation:
8x² - 5x + 3x(4 - 2x) =8x² - 5x + 3x*4 - 3x*2x
= 8x² - 5x + 12x - 6x²
Now add the like terms
= 8x² - 6x² - 5x + 12x
= 2x² + 7x
First way: x * 1.05
This computes directly what 105% of x will be.
Second way: x + (x * 0.05)
This takes x (which is 100%) and adds 5% of x to it.
