mestny [16]

We have been given that Tess ran $\frac{4}{3}$ kilo-meters each day for 2 days.

Let us find total distance traveled by Tess in 2 days by multiplying $\frac{4}{3}$ by 2 as:

$\text{Distance traveled by Tess in 2 days }=\frac{4}{3}\times 2$

$\text{Distance traveled by Tess in 2 days }=\frac{4\times 2}{3}$

$\text{Distance traveled by Tess in 2 days }=\frac{8}{3}$

We are also told that Cam ran $\frac{2}{3}$ kilo-meters each day for 5 days.

Let us find total distance traveled by Cam in 5 days by multiplying $\frac{2}{3}$ by 5 as:

$\text{Distance traveled by Cam in 5 days }=\frac{2}{3}\times 5$

$\text{Distance traveled by Cam in 5 days }=\frac{2\times 5}{3}$

$\text{Distance traveled by Cam in 5 days }=\frac{10}{3}$

Since $\frac{10}{3}$ km is greater than $\frac{8}{3}$ km, therefore, Cam ran more kilo-meters in total and option B is the correct choice.

Out of the 21 students in mrs Clark’s class by 3/7 of the class are boys

saul85 [17]

Answer:

There are 9 boys and 12 girls in mrs Clark's class

Step-by-step explanation:

We are given that mrs Clark has 21 students, of which 3/7 are boys

In order to find the number of boys, we multiply 21 by 3/7 which results in 9

This means there are 9 boys and then we just simply subtract 9 from 21 in order to find the number of girls 21-9=12

therefore there are 9 boys and 12 girls in mrs Clark's class

Given the equation 2 Square root of x minus 5 = 2, solve for x and identify if it is an extraneous solution.

leonid [27]

<span>2 square root (x - 5) = 2. 2^2 (x -5) = 2^2. 4(x - 5) = 4. 4x - 20 = 4. 4x = 24. x = 6. This solution is not extraneous, because extraneous solutions emerge from solving the problem but are not actually valid solutions for the initial problem. With rounding, this solution is valid for the initial problem.</span>
