Let the 1st number be x; 2nd number be y; 3rd number be z.
x + y + z = 79
x = number we are looking for.
y = x * 5 ==> 5 times the first
z = x + 16 ==> 16 more than the first
Therefor,
x + (x * 5) + (x+16) = 79
1st step, multiply the 2nd number: x * 5 = 5x
x + 5x + x + 16 = 79
Add all like numbers:
7x + 16 = 79
To get x, transfer 16 to the other side and change its sign from positive to negative.
7x = 79 - 16
7x = 63
To get x, divide both sides by 7
7x/7 = 63/7
x = 9
To check. Substitute x by 9.
x + (x * 5) + (x+16) = 79
9 + (9 * 5) + (9 + 16) = 79
9 + 45 + 25 = 79
79 = 79 equal. value of x is correct.
Answer:
−x+−7
Step-by-step explanation:
Let's simplify step-by-step.
4x−6−(5x+1)
Distribute the Negative Sign:
=4x−6+−1(5x+1)
=4x+−6+−1(5x)+(−1)(1)
=4x+−6+−5x+−1
Combine Like Terms:
=4x+−6+−5x+−1
=(4x+−5x)+(−6+−1)
=−x+−7
There are 2 different pillows, 2 different sheets and 3 different comforters.
Multiply all the choices together to find all the combinations:
Total combinations: 2 x 2 x 3 = 12
There are 12 different combinations.
