Two percent of Jennie’s skin cells were burned when she escaped from a fire. If 3.7×10^10 of her skin cells were burned then, ho

gulaghasi [49]

$1813\times10^9$ cells were not burnt when Jennie escaped from the fire.

<u>Solution:</u>

Given:

2% of skin cells were burnt i.e, $3.7\times10^{10}$ of skin cells were burnt.

To find:

Number of skin cells that were not burnt

We can write $3.7\times10^{10} \text{ as } 37\times10^{9}$

Therefore, by equating the values we get,

2% of the cell is $37\times10^9$

1% of the cell is $\frac{37\times10^9}{3}=18.5\times10^9$

As, 1% of the cell is $18.5\times10^9$

98% of the cell will be $98\times18.5\times10^9=1813\times10^9$

$\therefore \text{ skin cells that are not burnt is } 1813\times10^9$

The value of x and y which satisfies the equation : <br>9x+-5y=-34<br>

jarptica [38.1K]

Answer:
x=1
y=8.6

Explanation:

first start by assigning a random value to a random variable, let’s say x=1

from there the equation becomes solveable

9x1+-5y=-34
simplify
9-5y=-34
-9 from both sides
-5y=-43
divide both sides by-5
y=8.6

hope this helps :)
