LCM \(= 2×2×2×3×3=72\)

**25- Choice B is correct**The coordinate plane has two axes. The vertical line is called the \(y\)-axis and the horizontal is called the \(x\)-axis. The points on the coordinate plane are address using the form \((x,y)\). The point A is one unit on the left side of \(x\)-axis, therefore its \(x\) value is 4 and it is two units up, therefore its \(y\) axis is 2. The coordinate of the point is: (4, 2)

**26- Choice B is correct**\(α\) and \(β\) are supplementary angles. The sum of supplementary angles is 180 degrees.

\(α+β=180^\circ→α=180^\circ-β=180^\circ-125^\circ=55^\circ,\) Then, \(\frac{α}{β}=\frac{55}{125}=\frac{11}{25}\)

**27- Choice C is correct**Opposite number of any number \(x\) is a number that if added to \(x\), the result is 0. Then:

\(7+(-7)=0\) and \(4+(-4)=0\)

**28- Choice D is correct**\(-5<2x+7≤3\)→ (add (\(-7\))all sides) \((-7)+(-5)<2x+7+(-7)≤3+(-7) \) →\(-12<2x≤-4\)→(divide all sides by 2),\(-6<x≤-2\)

In inequality \(-6<x≤-2\), \(x\) is fewer or equal to \(-2\) and more than \(-6\). Only choice D represent the same inequality on the number line.

**29- Choice B is correct**A. Number of books sold in April is: \(690\)

Number of books sold in July is: \(1,150→ \frac{690}{1,150}≠2\)

B. Number of books sold in July is: \(1,150\)

Half the number of books sold in May is: \(\frac{1,150}{2}=575→690>575\) (it’s correct)

C. Number of books sold in June is: \(375\)

Half the number of books sold in April is: \(\frac{690}{3}=230→240<375\)
