Sam’s brother is 7 years older than Sam . His mother is 4 less than 3 times Sam’s age . Their combined age is 63 . How old is Sa
iren [92.7K]

Answer:

Sam is 12, sam's brother is 19, and sam's mom is 32.

Step-by-step explanation:

First the equation you need to use is S+7+S+3S-4=63(the variable s represents Sam), you combine the like terms which then equals 5S+3=63, then you use inverse operations. Subtract 3 on both sides, 5S=60, then you divide on both sides which equals S equals 12. Then you just plug in the number, S is Sam which means Sam's 12. Then 12+7 which is 19, Sam's brother. Then 3 times 12 minus 4 is 32. And if you check to make sure, 12+19+32 does equal 63.

wo neighboring homeowners, , 2, simultaneously choose how many hours to spend maintaining a beautiful lawn. The average benefit
Fantom [35]

To calculate the average benefit of hours we must add all the values then divide by the number of values that we have.

<h3>What is the average?</h3>

Average is a term that refers to a value that represents the mean of a group of values. For example, if my friends and I have a race to run from point A to point B and our times are:

  • 69 seconds.
  • 58 seconds.
  • 45 seconds.
  • 120 seconds.
  • 76 seconds.

The average time of my group of friends would be:

69 + 58 + 45 + 120 + 76 = 368

358 ÷ 73.6 seconds

The average of my group of friends would be 73.6 seconds.

According to the above, to identify the average profit per hour of my neighbors who own their lawns, you must use the same formula to obtain the result.

Note: This question is incomplete because the are some information missing. However I can answer it based on my prior general knowledge.

Geometry. Find the angle
lisabon 2012 [21]

Answer:

x = 10°; Angle A = 84°

Step-by-step explanation:

Angle A + Angle B = 180

5x + 34 + 2x + 76 = 180

7x + 110 = 180

7x = 70

x = 10

Angle A: 5(10) + 34 = 50 + 34 = 84°
