Answer:
Factor by grouping. (3r + 5)(r-3)
Step-by-step explanation:
-10 + a = 6a - 7a
Rearrange the left hand side
a - 10 = 6a - 7a
Simplify 6a - 7a
a - 10 = -a
Add a on both sides
2a - 10 = 0
Add 10 on both sides
2a = 10
Divide by 2 on both sides
a = 5
<span>The correct answer is point.
Explanation:
The definition of angle is "a figure formed by two rays that share a common endpoint." There are three "undefined terms" in geometry: point, line and plane. The only of these 3 needed for the definition of angle is point.</span>
The formulas and the equivalent formulas are
W = X - Y X = W +Y
W = X/Z - Y X = Z(W + Y)
W = (X - Y)/Z X = WZ+Y
W = XY X =W/Y
<h3>How to match the formulas?</h3>
To do this, we simply make X the subject of the formula in expressions on the left.
So, we have:
W = X - Y
This gives
X = W + Y
W = X/Z - Y
This gives
X/Z = W + Y
X = Z(W + Y)
W = (X - Y)/Z
This gives
X - Y = WZ
X = WZ + Y
W = XY
This gives
X =W/Y

<u>Complete question</u>
Match each formula on the left with an equivalent formula on the right.
W = X - Y X =W/Y
W = X/Z - Y X = Z(W + Y)
W = (X - Y)/Z X = WZ+Y
W = XY X = W +Y
