Answer:
y = -6
Step-by-step explanation:
Step 1: Define
8x - 9y = -50
x = -13
Step 2: Substitute and solve for <em>y</em>
8(-13) - 9y = -50
-104 - 9y = -50
-9y = 54
y = -6
Answer:
Step 1: Factor left side of equation.
(5x−1)(3x−5)=0
Step 2: Set factors equal to 0.
5x−1=0 or 3x−5=0
x=
1
/5
or x=
5
/3
Answer:
7/10 or 70%
Step-by-step explanation:
Add the number of each color of balls together to get the total
5 + 2 + 3 = 10
Add the number of all the balls that aren't black
5 + 2 = 7
Then divide how many balls that aren't black by the total. This gives us the probability the ball you choose is not black
7/10 = 0.7 or 70%
10 inches your hypotenuse is always going to be equal or bigger than the sum of the two sides
Answer:
11
Step-by-step explanation:
Do kcf (keep,change,flip)
First, covert 2 3/4 into an improper fraction
Then after you do that you get 11/4
so you do the equation 11/4 ÷ 1/4
when you do kcf it would be 11/4 × 4/1=
11/4×4/1=44/4 simplify divide both by 4 = 11
