Estimate 72.91 + 67.526 by first rounding each number to the nearest whole number
Vikentia [17]

Answer:

141

Step-by-step explanation:

First, you would round 72.91 to 73 because the number to the right of 7 is greater than or equal to 5, so you would round up. Same goes for 67.526. round both up to 73 and 68 then add. You would get an answer of 141 :)

Describe the possible values for x and y when ∣x − y ∣ > 0. What does it mean when ∣x − y ∣ = 0? Can ∣x − y ∣ < 0? Explain
Vilka [71]
The possible values for | x-y | > 0 is any number above 0. x must be greater than y. When | x-y | = 0, That means that x and y are equal to each other. | x-y | can not be less than 0, but it can equal 0.

Find the area. HELP PLEASE!!!!!!​
kaheart [24]

Answer:

616

Step-by-step explanation:

The equation to find the area of a trapezoid is:  A = ½ (b^1+b²) h.

b1=43

b2=45

h=14

Plug the variables in and solve.

A=\frac{1}{2} (43+45)14

A=\frac{1}{2} (88)14

A=\frac{1}{2} (1232)

A=616

Which is the correct answer ?????
Damm [24]
<h3>Answer:  True</h3>

Explanation:

Technically you could isolate any variable you wanted, from either equation. However, convention is to pick the variable in which isolating it is easiest, and most efficient.

The key thing to look for is if there's a coefficient of 1. This is found in the second equation for the y term. Think of -4x+y = -13 as -4x+1y = -13. Due to the coefficient of 1, when solving for y we won't involve messy fractions.

If you were to solve for y, then you'd get y = 4x-13, which is then plugged in (aka substituted) into the first equation. That allows you to solve for x. Once you know x, you can determine y.
