Answer:
x = − 4y + 16
x = − 6y + 24
Step-by-step explanation:
Let's solve for x.
x + 4y = 16
Step 1: Add -4y to both sides.
x + 4y + − 4y = 16 + − 4y
x = − 4y + 16
Answer:
x = − 4y + 16
Let's solve for x.
2x + 12y = 48
Step 1: Add -12y to both sides.
2x + 12y + − 12y = 48 + − 12y/2x= − 12y + 48
Step 2: Divide both sides by 2.
2x/2 = − 12y + 48/2x = − 6y + 24
Answer: x = − 6y + 24

<span>Josh swims 5 more hours per week than David so his hours = 3x + 5
His </span><span>average speed is 4 laps per hour less than David's so it is = x - 4
</span>
Total distance = hours * speed
= (3x + 5)*(x - 4)
= 3x^2 - 7x - 20
Ans is C
Answer:
30
Step-by-step explanation:
let number of questions in the test be x
9 of the first 10 questions are correct
so only x-10 questions remain
3/10 of the (x-10) = 3/10(x-10) questions are correct
scored 50% for the whole test
so only half of x = x/2 questions are correct
combining the above:
9+3/10(x-10) = x/2
9+3/10x-3=x/2
9-3=(1/2-3/10)x
1/5x=6
x=30
