Answer:

Step-by-step explanation:

If you were to factor the equation out you would get

(x-5x)(15-3)

Simplify it to

x(1-5) -3(-5-1)

Where you would then get

(x-3)(x-5)

Ramil and Carly collected the honey from 4 of his beehives. From the first hive collected 1/3 gallons of honey. The last hives y

BaLLatris [955]

Answer:

We know that:

First hive gave 1/3 gallon.
The other three hives gave 1/4 gallon each.

To find the total gallons of honey, we just have to sum all of it.

$H=\frac{1}{3}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4}\\H=\frac{1}{3}+3\frac{1}{4}\\H=\frac{1}{3}+\frac{3}{4}\\H=\frac{4+9}{12}=\frac{13}{12}$

As a mixed number:

$\frac{13}{12}=1\frac{1}{12}$

Therefore, Carly collected 1 and 1/12 gallons. Or, 1.08 gallons in total.

Question:70% of x is 63. 1.Write an equation that shows the relationship of 70%, x, and 63. 2. Use your equation to find x. Show

a_sh-v [17]

"x" represents an unknown number, we know that 70% of x equals 63.

To calculate the percentage of a number you have to multiply the said number by the percentage, in this case, 70%, and divide the result by 100:

So the 70% of x can be calculated as:

$\frac{70\cdot x}{100}=63$

You can simplify this expression by solving the division

$\begin{gathered} \frac{70}{100}x=63 \\ \frac{7}{10}x=63 \\ 0.7x=63 \end{gathered}$

Then the expression that shows you the relationship is

$0.7x=63$

Using this expression you can determine the value of x, to do so you have to divide both sides of the equal sign by 0.7

$\begin{gathered} \frac{0.7x}{0.7}=\frac{63}{0.7} \\ x=90 \end{gathered}$

The value of x is 90

If x-2m=p make m the subject. answer must be written as fraction.

siniylev [52]

To make m the subject, we must isolate it from everything else. To start, we can subtract x from both sides. This gives us:

-2m = p - x

After this, we divide both sides by -2 to finish isolating m. This would give us:

m = $\frac{p - x}{-2}$

Hope this helps! :)
