Answer:
y = x(4+z)+6
y-6 = x(4+z)
x=(y-6)/(4+z)
Step-by-step explanation:
35 - 27 = 8
15 - 8 = 7
She just payed off her best friend and has $8 left.
So she needs to earn $7 more to pay off the $15 she owes her mom
Answer:
If you meant [80 + (8*4) ]/2, then [80 + (8*4) ]/2=56
or if you meant 80 + [ 8*4 / 2], then 80 + [ 8*4 / 2] = 96
Step-by-step explanation:
Evalute the expression. 80 + (8x4) divided by 2
so do you mean
the whole expression 80 + (8x4) is over 2 ?
If so then:
evaluate 8x4 = 8 * 4 = 32.
so we have 80 + (8x4) is over 2 = (80 + 32)/2 = 112/2 = 56
If you meant 80 + [ 8*4 / 2]
then 80 + [ 8*4 / 2] = 80 + 8*2 = 80 + 16 = 96
Answer:
60 and 120
Step-by-step explanation:
The LCM of 12 and 15 is 60
The smallest natural number that would be a multiple of 12 and 15 would be 60.
To find the second number, all you do is multiply 60 by 2 and you get 120.
(60 * 2 = 120)
2a + 3b = 6
5a + 2b = 4
We multiply the first equation by 5 and the second by 2 and and subtract the second from the first:
10a + 15b = 30
-10a -4b = -8
11b = 22
b = 2
2a + 3(2) = 6
2a = 0
a = 0
Checking,
5(0) + 2(2) = 4
4 = 4, true
