The highest score on an algebra test was 42 points more than the lowest. When added together, the lowest and highest score was 1

dlinn [17]

Let us assume lowest score is = x.

We are given "The highest score on an algebra test was 42 points more than the lowest."

We took x for lowest score.

So, we need to write an expression for highest score in terms of x.

Therefore, the expression for highest score is = 42 more than x = x+42.

Is is also given that sum of both scores is 154.

We can setup and equation by using above statement.

Lowest score + Highest score = Total scrore.

x + x + 42 = 154.

Adding x and x we get 2x.

Therefore,

2x + 42 =154.

Subtracting 42 from both sides, we get

2x + 42-42 =154-42

2x = 112.

Dividing both sides by 2, we get

2x/2 = 112/2

x = 56.

Highest score = 56+42 = 98.

Therefore, highest score is 98 and lowest score is 56.

The diagonals of a square measure 14cm. Which is the length of a side of the square?

Sedaia [141]

The sides of a square have the same lengths, so the diagonal and two sides form a 45-45-90 right triangle. In a 45-45-90 triangle, the hypotenuse has a length with is $\sqrt{2}$ longer than the legs.

Therefore, the sides of the square would be $\frac{14}{ \sqrt{2} }$ .

Rationalize the fraction be multiplying the numerator and denominator by root 2.

$\frac{14 \sqrt{2} }{2}$

The 14 and 2 will reduce to 7, and the answer is A.
