5(5 + x) = 11(9 + x)

25 + 5x = 99 + 11x

Subtract 5x from both sides and 99 from both sides to get variables on one side and constants on the other.

25 - 99 = 11x - 5x

-74 = 6x

Divide by 6 on both sides to isolate the variable.

-74/6 = x or -12 and 1/3 = x

A hat is originally priced at $28 is on sale for $15% off. What is the total cost of the hat if the tax is 6.75%?

vampirchik [111]

You do 28, which is the original cost, then you take that 15% off to do that you multiply 28×.15 and you get 4.2 and subtract that from original cost and you get 23.8 then to get the cost after tax you do 23.8×.0675 and you get 1.6 then you add that to 23.8 and get 25.4 dollars

Find the slope of the line given two points:

vesna_86 [32]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(8, 10) and (-7, 14)

The slope is

$m = \frac{14 - 10}{ - 7 - 8} = \frac{4}{ - 15} = - \frac{4}{15} \\$

We have the final answer as

$- \frac{4}{15} \\$

Hope this helps you

I need help a problem 16

MakcuM [25]

Answer: The triangles are not congruent.

Step-by-step explanation:

We are given that the two triangles both contain a congruent angle and a congruent side. Additionally, the two triangles also share a side with each other, which is the center horizontal side (the one bisecting the two congruent angles). This "shared" side tells us that this side is congruent in both triangles, meaning that both triangles have two congruent sides with a non-included congruent angle among them.

However, because the two triangles only have two congruent sides, and the angle shared by each triangle is not included between the two sides, the triangle would be "congruent" by SSA, which is not a triangle congruency theorem or postulate.

Therefore, the two triangles are not congruent.

I hope this helps!

6. An air conditioning repair service call costs $75 per hour plus a flat fee trip charge of $25. If the situation can

Talja [164]

Answer:

THE ANSWER FROM YOUR OPTIONS IS:

(C) The repair charge r depends on the repair time h in hours.

Step-by-step explanation:

Repair-service call - $75 /hour

Flat fee trip-charge - $25

The function representing this situation: r(h) = 75h + 25

(A) Which is the dependent variable?

The dependent variable is the one whose value is to be gotten from the relationship between or among the values of other variables in the function. It usually appears at the left hand side of the equation. In this case, it is r(h).

(B) What do the variables represent?

The variables here - the algebra that can attain various values - are r and h.

r = total repair charges

h = repair time in hours [hence, if h = 1, repair time is 1 hour]

These are the two variables in this function.

r(h) now means repair charges in hours

THE ANSWER FROM YOUR OPTIONS IS:

(C) The repair charge r depends on the repair time h in hours.
