Answer:
13/12
Step-by-step explanation:
hope this helps loves x
<span>A = hours for plan A
B = hours for plan B</span>
<span>Monday: 6A + 5B = 7
Tuesday: 2A + 3B = 3</span>
use elimination by multiplying the 2nd equation by 3.
Doing that we get 3(2A + 3B = 3) = 6A + 9B
= 9
<span>So the two equations are now:
6A + 9B = 9</span>
6A + 5B = 7
Subtract and we have 4B = 2
B = 2/4 = 1/2 of an hour
Now put 1/2 back into either equation to solve for A
<span>6A + 5(1/2) = 7
6A + 5/2 = 7
6A = 14/2 -5/2
6A = 9/2
divide by 6 to get A = 9/12 = ¾ hours</span>
<span>Plan A = 3/4 hour</span>
<span> Plan B = 1/2 hour</span>
37 and 1/2 could mean:
37+ (1/2)
37 times 1/2
37+1/2=37 and 1/2 or 37.5
37 times 1/2=37/2=18 and 1/2=18.5
26.50 × 20%
= 26.50 × 0.2
= 5.30
26.50 + 5.30
= 31.80
since charissa doesnt want to leave coins/pennies on the table, you would round it up.
31.80 would then epual 32.00 due to the tenths being above 5 (an 8)
First, we calculate for the effective interest given the
annual interest and the condition that it is compounded monthly.
<span> Ieff = (1
+ 0.0925/12)^12 – 1 = 0.09652</span>
The equation that would best represent the value of
Grace’s money after x years is equal to,
<span>
An = ($1000)(1.09652)^x</span>
<span>Where x is the number of years</span>
