110 - 4x = x + 10
100 = 5x
x = 20
2x - 20 = 3y - 10
Plug in x
2(20) - 20 = 3y - 10
40 - 20 = 3y - 10
20 = 3y - 10
30 = 3y
y = 10
weekly salary is 650$
the number of days in a week is 7.
7 days salary is 650$
one day salary is 650/7
the number of days in semi month is 30/2 = 15 days
so the salary of semi month is 15*650/7 = 1392.85 $
so the salary of semi month is 1392.85 $.
Answer:x=18
Step-by-step explanation:
3(x-5)=x+21
Distribute the 3
3x-15=x+21
Add 15 to each side
3x=x+36
Subtract x from each side
2x=36
Divide each side by 2
x=18
X=375 because everything is multiplied by 15, y=15x, and 375*15=5625.
Y=6300 for the same reasoning: 420*15=6300
<u>so the answer is C</u>
I can’t really see number 7 but for number 10 the answer is 13x - 4y=8
