Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above and solve for P
4x+5y=7
y=3x+9
1) 4x+5(3x+9)=7 2) y=3(-2)+9
y= -6 +9
4x+15x+45=7 y=3
19x+45=7
19x= -38
x= -2
x is -2 and y is 3
Answer:
120
Step-by-step explanation:
Slope = rise / run
1/20 = 6 / run
run = 120
So there is 26 shirts in total because 4+8+4+10=26 Then you need to take 26-4=22. You do this because there is 26 total clothing and only 4 of them aren't either a blue piece of clothing or pants that means you have 22 pieces of clothing that are blue or pants. So your odds of picking a blue piece of clothing or pants is 22/26.
Hope this Helps!!
Find percent increase by subtracting the amounts and dividing it by the old amount, then multiply the result by 100 to make it a percent.
Increase= (277-210)/210
67/210
Then it ends up as 0.319047619...
Multiply that by 100 to make it a percent, which is..
31.9047619..
Round it off, and you get..
32%!
