Answer:

x = 18

Step-by-step explanation:

Given

$\frac{3x}{5}$ + 1 = $\frac{4x}{15}$ + 7 ( subtract 1 from both sides )

$\frac{3x}{5}$ = $\frac{4x}{15}$ + 6

Multiply through by 15 to clear the fractions

9x = 4x + 90 ( subtract 4x from both sides )

5x = 90 ( divide both sides by 5 )

x = 18

Answer:

See Explanation

Step-by-step explanation:

Given

$\triangle ABC = \triangle DE F$

Required

Which would not prove the similarity

$\triangle ABC = \triangle DE F$ implies that:

The following angles are congruent

$\angle A = \angle D$

$\angle B =\angle E$

$\angle C =\angle F$

And the following lengths are congruent

$AB = DE$

$BC =EF$

$CA = FD$

The options are not clear; so, it's a bit difficult to select the correct option.

<em>Any of the options that is different from the above list of 6 congruent pairs is the answer to your question.</em>

Answer:

Part A: Profit = 400 + 70 s, Part B : $3900

Step-by-step explanation:

Part A:

We know that the expression is: 0.2 ( 2000 + 350 s ). Using the distributive property :

Profit = 0.2 · 2000 + 0.2 · 350 s = 400 + 70 s

Part B :

The company's yearly profit when: s = 50 ( the total number of students )

P ( 50 ) = 400 + 70 · 50 = 400 + 3500 = $3900
