Answer: $19x
Step-by-step explanation:
If she bought 2 racing cars,
= $5x +$5x = $10x (Because one car is 5x)
And if she bought 3 motor cycles,
= $3x + $3x $3x = $9x
Now we get our total amount = $10x + $9x = $19x
Hope I could help! :)
Answer:
A) 16
Step-by-step explanation:
y = kx
16 = k*8
16/8 = k
k = 2
y = 2x
32 = 2x
32/2 = x
16 = x
Seven percent of 36.00 is 7 barred.
Let y be the temperature
Let m be the rate of temperature drop in degrees per hour
Let x be the number of hours elapsed since 8PM
The initial temperature (at x = 0) is 0
y = mx
Four hours from 8 PM, the temperature was -16.8 degrees
-16.8 = m(4)
m = -4.2 degrees per hour
At 9PM, one hour will have elapsed.
y = -4.2(1)
y = -4.2 degrees
Answer:
60 m
Step-by-step explanation:
since the triangles are similar, you can find the missing length d using the equation 140/105 = 80/d, then simplify
