1.) *13 hours of tandem bicycles were rented.*
The equation to use would be 12s+17t=519, where s is hours of standard bicycles rented and t is hours of tandem bicycles rented. It says that 22 hours of standard were rented so plug in 22 for s, giving you (12×22)+17t=519. And solve the equation from there.
2.) *C. 65g+55s=6500*
It says to use "g" for general admission tickets and that each costs $65. And use "s" for student admission tickets, with each costing $55. So just put the correct matching cost and variable that it stands for together.
3.) *A. distributive property*
So you start with the distributive property where you have to distribute -2(2x-5). So it should be:
Step 1: x - 2(2x) - 2(-5) = 8
Step 2: x - 4x + 10 = 8
Step 3: -3x + 10 = 8
Step 4: -3x + 10 - 10 = 8 - 10
Step 5: -3x = -2
Step 6: -3x ÷ (-3) = -18 ÷ (-3)
Step 7: x = 6
The problem started with step 1 with distributive property when they forgot to multiply the -2 to the -5, but instead they multiplied +2 which was wrong.
Answer:
The answer is b
Step-by-step explanation:
The answer is 88.8% how i got it is by:
30-18= 12 which is the number of member that had an average of 84
then multiply 12 times 84 = 1008 (keep this number)
last you multiply 18 by 92 which equals 1656
add 1008 and 1656 together and get 2664.
divide 2664 / 30 and you get the average of 88.8
Answer: 4 seconds
Step-by-step explanation:
We have the equation that models the height of the golf ball in feet after being hit.
When the ball reaches the ground its height is equal to zero.
Then to solve this problem you must equal h to zero and solve the equation for the variable t
Take 16t as a common factor
The equation is equal to zero when t = 0 and when t = 4
t = 0 is at the instant in which the ball has just been hit and t = 4 seconds is the instant in which the ball touches the ground.
Then the answer is t=4 seconds
