Answer:
The answer to your question is letter A. x = 0, y = 2/3
Step-by-step explanation:
Equation 1 2x + 3y = 2
Equation 2 x + 6y = 4
Solve the system of equations by elimination
- Multiply equation 2 by -2
2x + 3y = 2
-2( x + 6y = 4)
2x + 3y = 2
-2x - 12y = -8
0 - 9y = -6
y = -6/-9
y = 2/3
. Find x
2x + 3(2/3) = 2
2x + 2 = 2
2x = 2 - 2
2x = 0
x = 0/2
x = 0
Answer:
1/3
Step-by-step explanation:
Considering the triangles are similar the side lengths would be proportional too
like AB is similar to DE so 5/15 = 1/3
Answer:
76%
Step-by-step explanation:
Because there were 50 people present at his birthday, 50 will be our denominator. Only 38 people chose to eat it so that will be our numerator. 38 out of 50 people chose to have chocolate cake:
would be the fraction.
50x2 would be 100 and we need 100 to make it a percentage. We will multiply the bottom and the top by 2.
x 2 = 76/100 = 76%
76% of the people at the party picked chocolate cake.
1. 4800-2000=2800
This is the distance that the balloon needs to fall to reach an altitude of 2000 feet.
2. 2800/40=70
Distance/rate=time
The answer is 70 minutes.
