Andrew [12]

I think what you need to do is make B = -5
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1

Svetllana [295]

Answer:

$3y + 7 + 4y + 3 = 7y + 10$

Step-by-step explanation:

Given

$3y + 7 + 4y + 3 = [\ ]y + [\ ]$

Required

Simplify

We have:

$3y + 7 + 4y + 3$

Collect like terms

$3y + 7 + 4y + 3 = 3y + 4y + 7 + 3$

Evaluate like terms

$3y + 7 + 4y + 3 = 7y + 10$

Ramiro buys 50 packs of candy bars for $40 before a tax of 7.5%. He sells each candy var for 175% of what he paid before tax. ho

Zepler [3.9K]

Answer:

Cost price of each candy = $0.80, Selling price of each candy = $1.40

Step-by-step explanation:

Given:

Ramiro buys 50 packs of candy bars for $40 before a tax of 7.5%.

He sells each candy var for 175% of what he paid before tax.

Question asked:

How much does he buy each candy bar for ?

How much does he sell one for ?

Solution:

<u>By unitary method:</u>

Cost of 50 packs of candy bars = $40

Cost price of 1 pack of candy bars = $\frac{40}{50} =\$0.8$

Cost price of each candy = $0.80

Thus, he buy each candy bar for $0.80

Now:-

As he sells each candy var for 175% of what he paid before tax:-

Selling price of each candy = 0.80 $\times$ 175%

= $0.80\times\frac{175}{100} =\frac{140}{100}=\$1.4$

Thus, he sell one candy for $1.40

Step-by-step explanation:

$c = \sqrt{a ^{2} + b ^{2} } \\ = \sqrt{33 ^{2} + 44 ^{2} } \\ = \sqrt{1089 + 1936 } \\ = \sqrt{3025} \\ c = 55$
