The sum of the number is 103.the second number is 4 times the third.the third number is 5 more then the first .what are the numb
Zigmanuir [339]

Answer:

13, 18, 72

Step-by-step explanation:

let x-5 represent the first number, since the first number is 5 less than the third number. let x represent the third number. let 4x represent the third number, since it's four times greater than the third number.

set up an equation, and make it equal to 103:

x-5+x+4x=103

solve:

6x-5=103

6x=108

x=18

so, the third number is 18.

the first number is equal to x-5, so:

18-5=13

the second number is equal to 4x, so:

4(18)=72

so, the three numbers are 13, 18, and 72.

One supplementary angle is 15 degrees less than twice the other. Find the measure of the two supplementary angles.
Scilla [17]

Answer:

The measure of the two supplementary angles are 65 degrees and 115 degrees.

Step-by-step explanation:

The sum of supplementary angles is equal to 180 degrees. Let x and y are two angles such that,

x+y=180\ ....(1)

According to given condition,

One supplementary angle is 15 degrees less than twice the other, it means,

x=2y-15\ .....(2)

Putting the value of x from above equation in equation (1),

2y-15+y=180\\\\3y-15=180\\\\3y=195\\\\y=\dfrac{195}{3}\\\\y=65^{\circ}

Now put the value of y in equation (1), so,

x+65=180\\\\x=115^{\circ}

So, the measure of the two supplementary angles are 65 degrees and 115 degrees.
