X +15 + x + 15 + x + 15 = 3x + 45

divide by 3 from both of them, which eqauls 3(x + 15)

3(x+15)

There are 3 x's which = 3x

there are three 15's which = 15 + 15 + 15 = 45

your answer is 3(x + 15)

hope this helps

Constance wants to purchase an school jacket. She saw the same jacket at a few stores. Store A had the jacket for 15% off the or

Store A will be the better buy.

The price will be $53.70 after sales tax at store A.

Step-by-step explanation:

Price of Jacket at store A = $59.60

Discount = 15%

Discount Amount = $\frac{15}{100}*59.60\\$

Discount Amount = $0.15*59.60=\$8.94$

Price after discount = Original price - Discount amount

Price after discount = 59.60 - 8.94 = $50.66

Price of Jacket at store B = $50.99

The price at store A becomes less than store B after discount, therefore, buying from store A is better.

Sales tax = 6%

Sales tax amount = $\frac{6}{100}*50.66$

Sales tax amount = $0.06*50.66=\$3.0396$

Price after sales tax = Discount price at store A + Sales tax amount

Price after sales tax = 50.66 + 3.0396 = $53.6996

Rounding off to nearest hundredth;

Price after sales tax = $53.70

The price will be $53.70 after sales tax at store A.

Solve the equation. Check your solution.

VladimirAG [237]

-5x/6 + 1=7/18
lowest common multiple=18
-15x+18=7
-15x=7-18
-15x=-11
x=-11/-15=11/15

The solution set is [11/15]

we check it out.
-5(11/15) /6 + 1 =7/18
(-55/15) / 6 +1=7/18
-55/90 + 1=7/18
(-55+90) /90=7/18
35/90=7/18
7/18=7/18

If f(x) = -5x - 1 and g(x) = x - 6 what is (f g) (7)

Cloud [144]

You have

$(f\circ g)(x) = f(g(x)) \implies (f\circ g)(7) = f(g(7))$

So, we have to compute g(7) and feed it as input to f(x). We have

$g(7)=7-6=1 \implies f(g(7))=f(1)=-5-1=-6$

Write an algebraic expression to represent the verbal expression

MakcuM [25]

You set it up like this.

It says "the difference", so you put a minus sign: -
It says that the minuend, or the part being taken away from is a quantity equal to the product of 4 and "some number" (we'll use x), so now you have: (4 * x) -
Next, it says the subtrahend, or part being removed, is the square of "the number", meaning we use the "some number", x, from before, so now you have: (4 * x) - x^2
