Answer:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100
Step-by-step explanation:
Hi, to answer this question we have to write a system of equations with the information given:
Build time (hours) = 4c + 6a = 120
Test time (hours) = 4c + 4 a = 100
Where c represents the number of child bikes and a represents adult bikes.
So, for 20 child bikes and 6 adult bikes:
4 (20) + 6(6) = 120
4(20) + 4 (6) = 100

Answer:No
Step-by-step explanation:
Because:
60 divided by 12 equals 5
72 divided by 12 equals 6
So they all would not get a piece
Step-by-step explanation:
y = mx + c, where m is the slope of the line and c is the y-intercept.
We have y = 3x - 4 as line L.
Slope of line L = 3
=> Slope of line L2 = -1/3
We have y = -1/3 x + c as our line L2 equation.
When x = 9, y = 5.
=> (5) = -1/3 * (9) + c
=> 5 = c - 3, c = 8
Hence the answer is y = -1/3 x + 8.
The team won 4 gold medals, 4 silver medals and 10 bronze medals.
Step-by-step explanation:
Given,
Total medals won = 18
Ratio of gold, silver and bronze = 2:2:5
Let,
x be the original number.
Therefore,
Gold medals = 2x
Silver medals = 2x
Bronze medals = 5x
According to given statement;
Dividing both sides by 9
Gold medals = 2x = 2(2) = 4
Silver medals = 2x = 2(2) = 4
Bronze medals = 5x = 5(2) = 10
The team won 4 gold medals, 4 silver medals and 10 bronze medals.
