Answer: x = 6

Step-by-step explanation: To solve for <em>x</em> in this equation, we want to get <em>x</em> by itself on the left side of the equation.

Since <em>x</em> is being multiplied by 3, to get <em>x</em> by itself, we need to divide by 3 on the left side of the equation. Since we divide by 3 on the left side, we must also divide by 3 on the right side. On the left side, notice that the 3's cancel out so we are simply left with <em>x</em>. On the right side, we have 18 divided by 3 which is 6 so we have <em>x = 6</em>.

Finally, remember to check your answer by substituting a 6 back into the original equation. So we have 3(6) = 18 which is a true statement so our answer, <em>x = 6</em>, is correct. <em>Image if provided below</em>.

Answer:

The loose sweets at ?0.89 for 100 g.

Step-by-step explanation:

First, calculate the price per gram. You do this by dividing the price by the grams.

?1.49 / 120 g = 1.49 / 120 = 0.0124 (4 dp)

Because the answer was very long, I have rounded it to 4 decimal places (4 dp).

?0.89 / 100 g = 0.89 / 100 = 0.0089

Next, you must calculate both pre-packed and loose sweets to the same weight. I am calculating them both to 100 g.

0.0124 x 100 = 1.24

0.0089 x 100 = 0.89

Finally, the cheapest product for 100 g will be the better value. In this case, it is the loose sweets.

1. -28 = -3n + 5<br> what is n??<br> 2.5−n3=−4

STatiana [176]

Answer:

1.

n=11

2.

$n = \sqrt[3]{9}$

Step-by-step explanation:

Question 1:

The given equation is:

$- 28 = - 3n + 5$

Subtract 5 from both sides:

$- 28 - 5 = - 3n$

$- 33 = - 3n$

Divide boy sides by:

-3

$n = \frac{ - 33}{ - 3} = 11$

Question 2:

The given expresion is :

$5 - {n}^{3} = - 4$

Subtract 5 from both sides

$- {n}^{3}= - 4 - 5$

This implies that;

$- {n}^{3}= - 9$

${n}^{3}= 9$

$n = \sqrt[3]{9}$
