Answer:
50 Miles per hour
Step-by-step explanation:
To find the average speed divide the distance by the time it took to cover that distance
400/8=50
So the bus traveled 50 miles per hour on average.
30 ft. tall. You must find the ratios and compare. 2/20=3/x The best way I know to do this is to cross multiply. 2 times x and 20 times 3. So, 2x= 60. Divide by 2 and you get x =30. The height of the tree would be 30 ft. You could also find the proportion. 20/2= 10, so the height,x, over 3 would be equal to 10. 3 times 10 is equal to 30.
Answer:
In my best opinion I think the answer is E because...........
Step-by-step explanation:
A) 4 x 3 = 12
B) 4 x 4 x 4 = 64
C) 3 x 3 x 3 x 3 = 81
D) 2 x 2 x 2 x 2 x 2 x 2 = 64
and.....
E) NONE OF THE ABOVE! because you asked witch one equals 43 i solved them 4 times but i figured it out. None of the above!!
I hope i got the answer right, have a great day!!
-9 yards
5 sets of 3 yards
minus
2 sets of 12 yards
= -9
Remark. The easiest way to solve this is to make the coefficients of one of the letters = to the same coefficient in the other equation
Set up and solve
x + y = 24
3x + 5y = 100 Multiply the first equation by 3
<u>3x + 3y = 72 </u> Subtract
2y = 28 Divide by 2
y = 28/2
y = 14 <<<<<< Answer for y
Step 2
Solve for x
x + y = 24
x + 14 = 24 Subtract 14 from both sides.
x = 24 - 14
x = 10 <<<<Answer for x
Check to see if it works.
3x + 5y = 100
3*10 + 5*14 = 100
30 + 70 = 100 Checks.
