It only has two number sentences because 81 divided by anything else wont work only 9 would. Also since 9 times 9 is equal to 81
Answer:
1. g x 5 = b
2. f x 12 = in
3. luis' miles x 12 = fabian's miles
4. input x 1.5 = output
5. monica's weight - 5.6 lbs. = Lisa's weight
6. width x 2.5 = length
Step-by-step explanation:
Slope intercept form is y = mx + b where m is slope and b is y intercept.
The line crosses the y axis at y = 4
The slope is 4/3
So the answer is y = (4x/3) + 4
Answer:
B. 2x – 1 = 13 and x = 7
Step-by-step explanation:
We are given 4 equations and a solution for each. We have to tell which of the given solution satisfies the given equation.
Option A.
2x -1 = 13 and x = 6
Using this value in the equation, we get:
2(6) -1 = 13
12 - 1 = 13
11 = 13, which is not true. Hence this option is not valid
Option B.
2x - 1 = 13 and x = 7
Using the value in the equation, we get:
2(7) - 1 =13
14 - 1 =13
13 = 13, which is true. Hence this option is valid.
Option C.
2x + 1 =13 and x = 7
Using the value in the equation, we get:
2(7) + 1 = 13
15 = 13, which is not true. So this option is not valid
Option D.
2x - 1 = 13 and x = 11
Using this value in the equation, we get:
2(11) - 1 = 13
21 = 13, which is not true. Hence this option is not valid.
