Answer:
25
Explanation:
In order to solve this the easiest way you can use equivalent fractions.
Since 4 times 5 equals 20 we can multiply 5 times 5 to get our answer.
25 is the answer. But, if we couldn't have gotten to 20 through the multiplication we could use a proportion. That would look like the initial problem but instead of a "?" we would use a variable. I will use <em>t</em> for total.
So now we have our problem set up. The next step is to cross multiply. 4 by <em>t</em> and 5 by 20.
And now we can solve it like a normal algebra problem.
Either way, we get 25.
Answer:
1. 80
2. 20
3. 1080
Step-by-step explanation:
1. area= 1/2 x base x height
1/2 x 8 x 20= 80
2. first you find the rectangle which is 5x6=30
then the triangle base is 14-6=8
1/2x8x5=20
3. 12x15x6=1080

Step-by-step explanation:
Answer:
14 gallons of a gas more will she need to travel 240 miles.
Step-by-step explanation:
Proportion states that the two fractions or ratios are equal.
Let x represents the more gallons will she need to travel 240 miles.
As per the statement:
12 gallons of gas to travel 144 miles. Six gallons in the tank.
Then;
By definition of proportion:
Multiply 240 to both sides of an equation we have;
Simplify:
Subtract 6 from both sides we get;
Therefore, 14 gallons of a gas more will she need to travel 240 miles.
