Answer:

3j + 3m + 21

Step-by-step explanation:

Normally, they would each travel 3 miles, so the total would normally be 3j + 3m. However, for today, Jared ran another 21 miles, so 21 miles is added to the total.

Total distance = 3j + 3m + 21

Answer:

(3j) + (3m + 21)

Step-by-step explanation:

Since every time Jared goes running he runs 3 miles we should multiply j by 3. So we will have: 3j

Since every time Malia goes running she runs 3 miles we should multiply m by 3. So we will have 3m

But this month Jared ran an extra 21 miles so we will have to add that after we have multiplied both j and m by 3.

Since we want the total distance they ran that month, we need to add all of these distances.

This will give us 3j + 3m + 21.

In the answer options 3j is inside a parenthesis as well as 3m + 21. Since inside the parenthesis we only have addition and the order which we add doesn't really make a difference, the parenthesis were unnecessary but they won't affect the answer.

Sarah opens a small bag of chocolate candies and notices that out of 210 candies, 63 are brown. She assumes the color breakdown

mezya [45]

Answer:

1440

Step-by-step explanation:

We can solve this problem by applying the rule of three.

In fact, we know that:

- Over a package of 210 candies,

- The number of brown candies is 63

- Here we want to find what is the number of brown candies when the total number of candies contained in the package is 4800

So we can set up the following rule of three:

$\frac{x}{4800}=\frac{63}{210}$

where

x = number of brown candies when the total number of candies contained in the package is 4800

Solving the expression for x, we find:

$x=\frac{63}{210}\cdot 4800 =1440$

So, Sarah can expect to find 1440 brown candies in a package of 4800 pieces.

Simplify\:\sqrt[3]{27x^{15}}y^{24}

Free_Kalibri [48]

Answer:

$3x^{5}y^{24}$

Step-by-step explanation:

$\sqrt[3]{27x^{15}}y^{24} =$

$= \sqrt[3]{3^3x^{15}}y^{24}$

$= (3^3x^{15})^{\frac{1}{3}}y^{24}$

$= (3^3)^{\frac{1}{3}}(x^{15})^{\frac{1}{3}}y^{24}$

$= 3^{3 \times \frac{1}{3}}x^{15 \times \frac{1}{3}}y^{24}$

$= 3^1x^{5}y^{24}$

$= 3x^{5}y^{24}$

1.)
Starts with 40:10, then cuz you have 80 buns, you need to x2, so it would be 20 cubes

2.)
I don’t know, sorry

3.)
4:2 and 60 in total
so 4+2 is 6 and 60/6 is 10
so it would be 40:20 so 20
