Answer:
C = 20
Step-by-step explanation:
What happens if simultaneous Equations have two of the same variable like below? How would I solve it?
6A + 4B + 5C = 390
6A + 4B + 5.75C = 405
Step 1
We solve for C first
6A + 4B + 5C = 390....Equation 1
6A + 4B + 5.75C = 405... Equation 2
We substract Equation 1 from Equation 2
0.75C = 15
C = 15/0.75
C = 20
6:15 to 7:15 = $12 for the hour
7:15 to 7:45 Is a half hour = $6
So total $12 + $6 = $18
When a problem says that the price was increased by 100% + n%, it means you add on n% percent of the original price. In this problem, the original price was $35. The new price is 115% percent of the original price. So all we need to do is find 15% of the original price and add it onto the original price to find the new price.
$35 * 0.15 = $5.25
$35 + $5.25 = $40.25
The new price of the shoes is $40.25.
Answer:
10
Step-by-step explanation:
1x2x2.5=5
5/0.5=10
H time L for any thing.
But for this you have to split it in to 3 figures!
Look at pic then add them together! 24+24+4=52
I added another one just in case you dont get the first one!
