Answer:
12
Step-by-step explanation:
if the line is 18 inches long and a 1.5 space apart then u divide them and 18 divided by 1.5 is 12
-13 (q + 4) = 7q + 16
I think to solve it you do this first:
-13q + -52 = 7q + 16
And then I think you do:
-6q + -36
And thats all I can remember sorry ):
Or
That -6q + -36 might be the answer I think (:
Hope I could help (:
Given the equation 2y = 5x - 3:
A way to find out which of the ordered pair options lie on the line is to substitute their coordinates into the equation.
A) (2, 5)
2y = 5x - 3
2(5) = 5(2) - 3
10 = 10 - 3
10 = 7 (False statement). this means that (2, 5) is not a solution to the given equation.
B) (6, 3)
2y = 5x - 3
2(3) = 5(6) - 3
6 = 30 - 3
6 = 27 (False statement). this means that (6, 3) is not a solution to the given equation.
C) (3, -6)
2y = 5x - 3
2(-6) = 5(3) - 3
-12 = 15 - 3
-12 = 12 (False statement). this means that (3, -6) is not a solution to the given equation.
D) (3, 6)
2y = 5x - 3
2(6) = 5(3) -3
12 = 15 - 3
12 = 12 (True statement). This means that (3, 6) IS a solution to the given equation.
E) (2, -5)
2y = 5x - 3
2(-5) = 5(2) - 3
-10 = 10 - 3
-10 = 7 (False statement). this means that (2, -5) is not a solution to the given equation.
Therefore, the correct answer is Option D: (3, 6).
1 + (-5/8) = 3/8
Explanation: If the coffee wasn’t drank it would’ve been at fraction 1 (or 100%)
Since he drank 5/8 of it. The coffee left is now 1-(5/8)
But since the question has asked to give the equation in addition format. Put a plus sign in between the two.
Therefore,
1 + (-5/8)
Solve it,
= 1-(5/8)
= (8-5)/8
= 3/8
Hence the equation is:
1 + (-5/8) = 3/8.
