Cost of the article = $27.50
Amount of city sales tax = (27.50 x 6%) = $1.65
Amount of excise tax = (27.50 x 8%) = $2.20
From my knowledge, we pay city sales tax and federal excise tax when we buy something, so the total cost would be $31.35
F(g(x)) where you see an 'x' in f(x) put a g:
f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!
I let the second one for you. Sorry if you disagree!
Answer:
90 of the students are girls.
Step-by-step explanation:
Boys : Girls
B : G
4 : 3
120 : ?
(120 ÷ 4 = 30) so 4 × 30 = 120
(Do this to the other side) 3 × 30 = 90
B : G
120 : 90 [90 girls out of 210 total students]
Hope this helps. :)
Answer:
That's Thomas the Train, but someone edited him with glowing red eyes
Step-by-step explanation:
Simplifying
15a + 7b = 0
Solving
15a + 7b = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-7b' to each side of the equation.
15a + 7b + -7b = 0 + -7b
Combine like terms: 7b + -7b = 0
15a + 0 = 0 + -7b
15a = 0 + -7b
Remove the zero:
15a = -7b
Divide each side by '15'.
a = -0.4666666667b
Simplifying
a = -0.4666666667b
