Answer:

x = 3

ST = 24

Step-by-step explanation:

if T is the midpoint then ST = TU

8x = 2x + 18 move like terms to the same side

8x - 2x = 18 subtract like terms

6x = 18 divide both sides by 6

x = 3 to find ST replace x with 3

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is

Dennis_Churaev [7]

Answer:

The test contains 10 three-point questions and 14 five-point questions

Step-by-step explanation:

Given equations are:

$x+y = 24\\and\\3x+5y=100$

From 2nd equation we can deduce that x represents number of 3-point questions and y represents number of 5-point questions.

Using the substitution method:

From x+y = 24

y= 24-x

Putting this valu of y in 3x+5y=100

$3x+5(24-x) = 100\\3x + 120 - 5x = 100\\-2x+120=100\\-2x = 100-120\\-2x = -20\\\frac{-2x}{-2} = \frac{-20}{-2}\\ x = 10\\Putting\ the\ value\ of\ x\ in\ x+y=24\\10+y=24\\y = 24-10\\y = 14$

Hence, the correct answer is:

The test contains 10 three-point questions and 14 five-point questions..
