The sum of three numbers is 117 . the third number is 3 times the second. the first number is 8 less than the second. what are the numbers?

The numbers are :17, 25 and 75

Step-by-step explanation:

Let the second number of x.

The third number is 3 times the second = 3x

The first number is 8 less than the second = x-8

the sum of three number are = 117

First number = x-8 = 25 - 8 =17

Second number = x = 25

Third number = 3x = 3 × 25 =75

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
