Nata [24]

Answer:

The money Rachael plan to collect for the shelter is <u>$350</u>.

Step-by-step explanation:

Given:

Rachel is collecting donations for the local animal shelter.

So far she has collected $245, which is 70% of what she hopes to collect.

Now, to find the money Rachael plan to collect for the shelter.

Let the total amount Rachael plan to collect be x.

Amount she collected = $245.

Percentage of amount she collected = 70%.

Now, to get the amount Rachael plan to collect we put an equation:

70\%\ of\ x=\$245.

⇒ \frac{70}{100} \times x=245

⇒ 0.70\times x=245

⇒ 0.70x=245

<em>Dividing both sides by 0.70 we get:</em>

⇒ x=\$350.

Therefore, the money Rachael plan to collect for the shelter is $350.

Write an equation and solve: Your math homework has 6 more than three
lorasvet [3.4K]

Answer: 33 math problems.

Step-by-step explanation:

Let x = Number of math problems

y= Number of history problems

According to the question , we have

3y+6=x\ \ \ \ \ (i)\\\\ x+y=42\ \ \ \ (ii)

We can rewrite (i) as x-3y=6    (iii)

Now, subtract (iii) from (ii), we get

y-(-3y)=42-6\\\\\Rightarrow\ y+3y=36\\\\\Rightarrow\ 4y=36\\\\\Rightarrow\  y= \dfrac{36}{4}\\\\\Rightarrow\  y=9

Put this in (i), we get

x=3(9)+6 = 27+6=33

Hence, you have to complete 33 math problems.
