Answer:
18 inches
Step-by-step explanation:
Rick is building a scale model of the Alamo.
We are given a scale that 3 in. = 15 ft.
The length of the Alamo is 90 feet.
What is the length of the scale model in inches?
So we know that for every 15 feet, 3 inches are actually used in the project and we need a total of 90 feet. To solve, we need to find how many times 15 goes into 90, in which the number it multiplies to will apply to the inches.
15 * ? = 90
90 / 15
6
It takes 15 6 times to get to 90, meaning that we need to multiply 3 inches 6 times to find the actual length of the scale model in inches.
3 * 6
18 inches.
The formula after making t subject of the formula is:
Step-by-step explanation:
Given formula is:
To make t the subject of the formula we have to isolate t
So,
<u>Cross-multiplying</u>
<u>Adding 4t on both sides</u>
<u>Subtracting 3q from both sides</u>
<u>Taking t common on left hand side</u>
<u>Dividing both sides by q+4</u>
The formula after making t subject of the formula is:
It’s the number 3 hope this helps

</span>That is an expression. Make sure you don't put the "=" sign since it would become an EQUATION if you did.
Answer:
11 quarters
Step-by-step explanation:
First, I subtract : 3.45 - .70 = 2.75
Then, divide : 2.75 by 25 ( a quarter ) = .11
Check : 11 x 25 = 2.75 -------------> 2.75 + .70 = 3.45
Hope this helps :)
