Answer:
You have a 0.8 / 80% of NOT picking the blue marbles.
Step-by-step explanation:
5 + 7 + 3 = 15
15 - 3 = 12
12 / 15 = 0.8 = 80%
Formula Multiply the number by -3/4
The number 48 is 3/4 of 64 but it is negative so the result of -48 should be multiplying 64 by negative 3/4
64x-3/4 =-48
after 48 will be a positive number since (-)x(-)=(+)
So it will be alternating positive and negative
Gavin had 20 minutes to do a three-problem quiz.
He spent 9 3/4 minutes on problem 1.
He spent 3 4/5 minutes on problem 2.
How much time did he have left for problem 3?
We need to add the time spent on problem 1 and problem 2 and then subtract the sum from the total time.
Simplify the above fraction
Let us write the answer in mixed number
Finally, convert the fractional part to seconds by multiplying the fractional part by 3
This means that there are 6 minutes and 27 seconds are left for problem 3.

It has a constant slope.
Answer:
A belt costs $15 and a wallet costs $27.
Step-by-step explanation:
Let's mark price of a belt with x and price of the wallet with y. That leaves is with a system of equations:
x + y = $42
7x + 4y = $213
The goal when solving this system is to get rid of one of the variables. We can do that by multiplying first equation with -4:
-4x - 4y = -168
7x + 4y = 213
Now, we simply add these two equations up:
-4x - 4y + 7x + 4y = -168 + 213
3x = 45
x = $15
Now, we plug in x into any of the two starting equations to find y:
x+y=42
15 + y = 42
y = $27
