Answer:
85
Step-by-step explanation:
The number you Add with goes up by 2 with each equation. Since five is the first number,
5+3=8 (Pattern #2)
8+5=13 (Pattern #3)
13+7=20 (pattern #4)
20+9=29 (pattern #5)
29+11=40 (pattern #6)
40+13= 53 (pattern #7)
53+15=68 (pattern #8)
68+17=85 (pattern #9)
Step-by-step explanation:
So, we will take one of the numbers = x
And the other is 12 more than 3 times it, so = 3x + 12
So they said if we add them, we will get 4
So x + (3x + 12) = 4
4x + 12 = 4
4x = 4 - 12
4x = - 8
x = - 8 ÷4
x = - 2
So one of the numbers x = - 2
The other is 3x + 12
So x = - 2
3x +12 = 3(-2) + 12
= 6
So the 2 numbers = 6 and - 2
Lets check!
6 + (-2) = 4
So it's right!
<span><span>15 times 9.25 = 138.75 inches.
That leaves
144-138.75 = 5.25 inches for spaces.
Between the 15 boards are just 14 spaces, however.
So divide 5.25 by 14 and get
3/8" for each space.</span>

<span>Hi there,
14 boards each 9 1/4 inches wide.
14 x 9 1/4 = 138 3/4 inches
144 inches - 138 3/4 inches
= 5 1/4 inches
Spaces between 14 boards
= 13 spaces.
5 1/4 / 13 = 2/5 of an inch.
Hope this helps. :-)</span></span>
Answer:
Your answer should be (B.) Both calculated the slope as 1 over 3
Step-by-step explanation:
First of all, it has to be A or B. The question does say that they have to calculate it accurately. You can't do that if they are both different. Second, remember rise over run. The rise of the first triangle is 2, and the run is 6. Simplify that to get 1/3. Now, we can stop there because B is the only possible answer.
Hope I helped! =)
