Christopher scored 7 more than two times the questions Mathew scored on the math test. If Christopher scored 87 on the math test

, what was Mathew's score?
Mathematics
1 answer:
viktelen [127]3 years ago
7 0

Answer:

40

Step-by-step explanation:

To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:

C = 2M + 7

(Variables are representative of the first letter of each name)

Seeing as Christopher scored 87, we can put that into the equation and solve for M.

So, the equation will be:

87 = 2M + 7

Subtract 7 from both sides in order to isolate variable M on the right side.

80 = 2M

Now solve for M, which is 40 (divide both sides by 2).

Write a equation of the line below
yulyashka [42]

Answer:

y = -x + 1

Step-by-step explanation:

The slope-intercept formula is y = mx + b where m is the slope and b is the y-intercept. Since slope is...

m = \frac{rise}{run}

this means that the slope of the line is -1 (the rise is -1, the run is 1, -1/1 = -1). By looking at the graph you can also see that the line goes through 1 on the y-axis, so the y-intercept is 1. By plugging in the appropriate values, the equation of the line is y = -1x + 1 or just y = -x + 1

A person can see the top of a building at an angle of 65°. The person is standing 50 ft away from
zhannawk [14.2K]

9514 1404 393

Answer:

  (b)  112.2 ft

Step-by-step explanation:

The relevant trig relation is ...

  Tan = Opposite/Adjacent

For the given geometry, this becomes ...

  tan(65°) = (height above eye level)/(50 ft)

Then we have ...

  (height above eye level) = (50 ft)tan(65°) = 107.2 ft

Adding the height of eye level will give us the height of the building.

  building height = (eye level height) + (height above eye level)

  building height = (5 ft) + (107.2 ft)

  building height = 112.2 ft

A table and 8 chairs weigh 235.68 lb together. If the table weighs 157.84 lb, what is the weight of one chair in pounds?
Alona [7]

Answer: 9.73 lb each chair

Step-by-step explanation:

You substract the weight of the table alone from the full weight:

235.68 - 157.84=77.84

Then you divide 77.84 by 8 chairs and you obtain the weight of each individual chair

77.84/8= 9.73 the weight of each individual chair
