Jim thinks of a number (n). He adds 5 to the

Karolina [17]

Answers + Step-by-step explanation :

a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign

b) we can solve our equation to find for n, the number jim thought of

7(n + 5) = 91
I will use the distributive property.

7n + 35 = 91

Subtract 35 on both sides

7n = 56

Now divide 7 on both sides to find n

n = 8

The number Jim was thinking of was 8! this should be correct, hope this helps!

In bioligy class cher is viewing cells with a microscope. cell h measures 8.76x10^-3 microns in diameter and cell v measures 2.1

3241004551 [841]

Answer:

Larger cell 400 times bigger cell than the smaller cell

Step-by-step explanation:

Given:

diameter of the cell h = $8.76\times10^{-3}$

diameter of the cell v = $2.19 \times10^{-5}$

To Find:

How many tines larger is the bigger cell than the smaller cell?

Solution:

The cell h with diameter $8.76\times 10^{-3}$ is larger and the cell v with diameter $2.19 \times 10^{-5}$ is small. To find the number of times it is larger, we can divide the larger cell diameter by smaller cell diameter

=> $\frac{8.76\times 10^{-3}}{2.19 \times 10^{-5}}$

=> $\frac{8.76\times 10^ {-3} \times 10^{5}}{2.19 }$

=> $\frac{8.76\times 10^ {(-3+5)}}{2.19 }$

=> $\frac{8.76\times 10^2}{2.19 }$

=> $\frac{876}{2.19}$

=> 400

Larger cell is the bigger cell than the smaller cell by 400 times
