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 + 1) ( x + 4)
Step-by-step explanation:
Answer: 0
Step-by-step explanation:
To find slope, I found that an easy way is the equation y2 - y1 over (divided by) x2 - x1
so for this, it would be:
which is 0/7
0 divided by 7 is 0, so there is your answer
Answer:
- 56
Step-by-step explanation:
The opposite of a number is its negative value
Then the opposite of 56 is - 56
I THINK the answer is 6000 square feet because each one is 6 square feet and you have 1000 of them so 6 square feet times 1000 squares is 6000 square feet.
