Answer:
y = - 12.5
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use the condition x = - 5 when y = 10, then
k = yx = 10 × - 5 = - 50
y = ← equation of variation
When x = 4, then
y = = - 12.5
Simplify the expression: -108c
<u>Answer:</u>
2.06 hours
<u>Step-by-step explanation:</u>
Money saved by Jordan to buy a $80 video game = × =
So Jordon needs 80 - 64 = $16 more to get the video game
He gets $7.75 per hour by working, so assuming the number of hours to be x he needs to work to get $16, we can write it as:
Therefore, Jordan needs to work at least for 2.06 hours to save the rest of the money for the video game.
d = 2(4 + c)
adding 4 and c, which is the sum, and multiplying that by 2 will give us d.
