3/4 +4/5
find the common denominator which is 20
multiply by 5 for 3/4
(3)(5)/(4)(5)=15/20
multiply by 4 for 4/5
(4)(4)/(5)(4)=16/20
15/20+16/20
=31/20
answer:
31/20, 1 11/20 and 1.55
When using estimation, we usually will round up or down depending.
162= rounds down to 160
4.75= rounds to 5
160*5= 800
It travels around 800 miles in 5 hours.
I hope this helps!

<h3>How to solve an equation</h3>
Your information is incomplete. Therefore, an overview will be given. Let's assume that the price of a jawbreaker is 0.45.
Therefore, the cost of 21 jawbreakers will be:
= 21 × 0.45
= 9.45
In this case, the person has 8.32. Therefore, it can be noted that she doesn't have enough money.

Step-by-step explanation:
90-65=25 right angle is 90 degrees minus the 65
A system of equations with infinitely many solutions is a system where the two equations are identical. The lines coincide. Anything that is equal to

will work. You could try multiply the entire equation by some number, or moving terms around, or adding terms to both sides, or any combination of operations that you apply to the entire equation.
You could multiply the whole thing by 4.5 to get

. If you want, you could mix things up and write it in slope-intercept form:

. The point is, anything that is equivalent to the original equation will give infinitely many solutions x and y. You can test this by plugging in values x and y and seeing the answers!
The attached graph shows that four different equations are really the same.
