Factor 21c+24.<br> Write your answer as a product with a whole number greater than 1.<br> use ()

Lera25 [3.4K]

Answer:

The required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

Step-by-step explanation:

Given the expression

$21c+24$

Determining the factor

$21c+24$

Rewrite 24 as 3 · 8

Rewrite 21 as 3 · 7

so the expression becomes

$21c+24=3\cdot \:\:7c+3\cdot \:\:8$

Factor out the common term 3

$=3\left(7c+8\right)$

Therefore, the required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

PLZ ANSWER APSP IM IN THE TEST RN!!!

olchik [2.2K]

Answer:

x = 38

y = 25

Step-by-step explanation:

To find x, you do

(2x + 5) = (3x - 33)

Subtract 2x from both sides to isolate x on one side, you get:

5 = (x - 33)

Add 33 to both sides to separate the normal number from the x, you get:

38 = x

From there, you plug x into one of the equations

2(38) + 5

The answer's 81, meaning that angle is 81 degrees. Using supplementary angles, you can find that angle ACD = 99, which you can use to find angle BCE. You'll get this equation:

(4y - 1) = 99

Add one to both sides to get rid of it, you get:

4y = 100

Divide by four, to get the y all alone:

y = 25

I hope this helped!

A box of 42 chocolates contains milk and dark chocolates in the ratio of 3:4. How many chocolates of each type there are?

Elza [17]

<h2>Answer:The number of milk chocolates are 18 and the number of dark chocolates are 24.</h2>

Step-by-step explanation:

Let the number of milk chocolates be $m$ .

Let the number of dark chocolates be $d$ .

Given that the box contains the milk and dark chocolates in the ratio $3:4$ .

So, $\frac{m}{d}=\frac{3}{4}$ ...(i)

Given that the total number of chocolates are $42$ .

So, $m+d=42$ . ...(ii)

Using (i) and (ii),

$m+\frac{4}{3}m=42$

$\frac{7}{3}m=42$

$m=18$

$d=\frac{4}{3}m=\frac{4}{3}\times 18=24$

So,the number of milk chocolates are $18$ and the number of dark chocolates are $24$ .
