Answer:
75
120
Step-by-step explanation:
Let the first mechanic's hourly rate = x
Let the second mechanic's hourly rate = y
x + y = 195
15x + 5y = 1725 Divide this equation by 5
3x + y = 345 Write the first equation below this one. Subtract
<u>x + y = 195</u>
2x = 150 Divide by 2
x = 150/2
x = 75
====================
x + y = 195
75 + y = 195
y = 195 - 75
y = 120
In converting a decimal to a percent you just need to multiply it by 100.
Solution on the problem above:
3.45 x 100 = 345%
Therefore the answer is letter A.
It will be vice versa in converting percent to decimal. You just need to divide it by 100.
For example, we convert the 345% to decimal:
345%/100 = 3.45
When pam saves 2, brother saves 5
so if Pam has 40
40/2 (the number of dollars Pam saves) = 20
20 x 5 = 100 ( the number of dollars her bro saves)
her bro has 100 dollars
hope this helps
basically divide 2 from 40 and then multiply the answer with 5, and you get the number of money her bro saves
hope this helps
Answer:
13-n=4
Subtract both sides by 13
-n=-9
n=9
Step-by-step explanation:
13 less means - and a number means n that you don’t know. is means = sign. And so we get the answer that I gave you. Thank you
