<h2>Greetings!</h2>

Answer:

x = 67.5

Step-by-step explanation:

Because AB and NP lines are parrallel, we can find out the scale factor by dividing size MA by MN.

This works because you find out what the MA size has to be multiplied to to get to MN, which will also work in reverse to find angle MB from MP.

71.5 - 22 = MA = 49.5

71.5 ÷ 49.5 = \frac{13}{9}

So to get to line MP length, line MB had to be multiplied by \frac{13}{9} to get 97.5

The reverse of this is dividing 97.5 by \frac{13}{9}:

97.5 ÷ \frac{9}{13} = 67.5

So x = 67.5


<h2>Hope this helps!</h2>

We subsituete

9:6=6:4
treat as fraction
9/6=6/4

9/6=3/3 times 3/2
6/4=2/2 times 3/2

3/2=3/2
this is TRUE

Complete question is;

The levels of mercury in two different bodies of water are rising. In one body of water the initial measure of mercury is 0.05 parts per billion (ppb) and is rising at a rate of 0.1 ppb each year. In the second body of water the initial measure is 0.12 ppb and the rate of increase is 0.06 ppb each year.

Which equation can be used to find y, the year in which both bodies of water have the same amount of mercury?

A) 0.05 – 0.1y = 0.12 – 0.06y

B) 0.05y + 0.1 = 0.12y + 0.06

C) 0.05 + 0.1y = 0.12 + 0.06y

D) 0.05y – 0.1 = 0.12y – 0.06

Answer:

Option C: 0.05 + 0.1y = 0.12 + 0.06y

Step-by-step explanation:

In the first body, the initial measure of mercury is 0.05 parts per billion (ppb) while it's rising at a rate of 0.1 ppb each year. We are told to use y for the number of years.

Thus, amount of mercury for y years in this first body is;

A1 = 0.05 + 0.1y

Now, for the second body, we are told that;the initial measure is 0.12 ppb and the rate of increase is 0.06 ppb each year.

Thus, amount of mercury for y years in this second body is;

A2 = 0.12 + 0.06y

Since we want to find the year in which both bodies of water have the same amount of mercury. Thus, it means;

A1 = A2

Thus;

0.05 + 0.1y = 0.12 + 0.06y

60% of 90 is 54 by doing 90*60/100
2/3 of 150 is 100 because 150 divided by 3 times 2 is 100
and dawn sold 46 cookies.

if you add all the cookies sold up, you get 200 cookies.
Dawn having sold 46 cookies out of the 200, if you want to have a percentage, you have to change that 200 which is the total into 100.

So 200/2=100 and 46/2=23 

Dawn sold 23 cookies for every 100 cookies sold so 23%
