Answer:

<h2>Subtract 3x from both sides</h2>

Step-by-step explanation:

3x - 5 = 7x + 11

Firs step:

add 5 to both sides: 3x - 5 + 5 = 7x + 11 + 5 → 3x = 7x + 16

or

subtract 7x from both sides: 3x - 7x - 5 = 7x - 7x + 11 → -2x - 5 = 11

or

subtract 3x from both sides: 3x - 3x - 5 = 7x - 3x + 11 → -5 = 4x + 11

or

subtract 11 from both sides: 3x - 5 - 11 = 7x + 11 - 11 → 3x - 16 = 7x

If you want solution.

3x - 5 = 7x + 11       <em> subtract 3x from both sides</em>

3x - 3x - 5 = 7x - 3x + 11

-5 = 4x + 11         <em>subtract 11 from both sides</em>

-5 - 11 = 4x + 11 - 11

-16 = 4x            <em>divide both sides by 4</em>

-16/4 = 4x/4

-4 = x → x = -4

Which is greater 15/27 or 16/24
Artemon [7]

Answer:

16/24

Step-by-step explanation:

let’s use the GCF of both which is 3 for 15/27

15/27 divided by 3 is 5/9

for 16/24 the gcf is 8

16/24 / 8 is 2/3

now we have to multiply 2/3 times 3

2/3 times 3 6/3 which is 2

so 16/24 is greater.

Rasheed bought two kinds of candy bars, chocolate and toffee, that came in packages of 2 bars each. He handed out 2/3 of the cho
Contact [7]

Answer:

9 packages of chocolate bars

Step-by-step explanation:

Let he bought c packages of chocolate bars and t packages of toffee bars,

Since, he bought 1 fewer package of chocolate bars than toffee bars.

⇒ c = t - 1  -----(1)

Also, he handed out out \frac{2}{3} of the chocolate bars and \frac{3}{5} of the toffee bars,

If he handed out the same number of each kind of candy bar.

\implies \frac{2}{3}\times c=\frac{3}{5}\times t

10c = 9t     ( By cross multiplication )

\implies t=\frac{10}{9}c    ( Division property of equality )

From equation (1),

c=\frac{10}{9}c-1

1=\frac{10}{9}c-c

1=\frac{10c-9c}{9}

1=\frac{c}{9}

\implies c = 9

Hence, he bought 9 packages of chocolate bars.
