I DON’T GET THIS ONLY NEED NUMBER 6 PLEASEEE!!!!!

$\huge\text{Hey there!}$

$\huge\text{The word \bf{product}}\huge\text{ means multiply in}\\\huge\text{mathematics.}$

$\huge\text{The number is unknown so we can label}\\\huge\text{it as: x}$

$\huge\text{Your equation will be setup like this: -2.5x = 60}$

$\text{-2.5x = 60}\\\text{First divide both sides by -2.5}\rightarrow\dfrac{-2.5\text{x}}{-2.5} = \dfrac{60}{-2.5}\\\text{Cancel out:}\dfrac{2.5\text{x}}{2.5}\text{ because it equals 1}\\\\\text{Keep:}\dfrac{60}{-2.5}\text{because it helps us find the unknown number}\\\\\\\boxed{\boxed{\text{Answer: x = -24}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$

Williiam lost 25% of his marble,gave 1/6 of the remainder to his.Brother and had 120 marbles left.How many marbles did he have a

bija089 [108]

Answer:

Number of marbles with Williams at the starting = 192

Step-by-step explanation:

Let total number of marbles with Williams = m

He lost marbles = 25% of the total number

= $\frac{25}{100}\times m$

= $\frac{m}{4}$

Remaining marbles with Williams = m - $\frac{m}{4}$

= $\frac{3m}{4}$

He gave marbles to his brother = $\frac{1}{6}$ th of the remaining marbles

= $\frac{1}{6}\times \frac{3m}{4}$

= $\frac{m}{8}$

Remaining marbles after giving marbles to his brother = 120

Therefore, $\frac{3m}{4}-\frac{m}{8}=120$

$\frac{6m}{8}-\frac{m}{8}=120$

$\frac{5m}{8}=120$

m = $\frac{120\times 8}{5}$

m = 192

Number of marbles with Williams at the starting = 192

PLEASE ANSWER!!! You are helping wish some repairs at home. you drop a hammer and it hits the floor at a speed of 12 feet per se

Andru [333]

Answer:

h = 2.25 m

Step-by-step explanation:

<u><em>Given:</em></u>

Speed = v = 12 ft/sec

Acceleration due to gravity = g = 32 ft/sec²

<u><em>Required:</em></u>

Height = h = ?

<u><em>Formula:</em></u>

v = $\sqrt{2gh}$

<u><em>Solution:</em></u>

For h, the formula will be:

=> h = $\frac{v^2}{2g}$

=> h = $\frac{(12)^2}{2(32)}$

=> h = $\frac{144}{64}$

=> h = 2.25 m
