Answer:
Yes
Step-by-step explanation:
To solve, evaluate each equation when x = 4.
Rewrite: 4[2 + 3(4)]
Multiply: 4(2 + 12)
Add: 4(14)
Multiply: 56
Final answer: 56
Then,
Rewrite: 8 + 12(4)
Multiply: 8 + 48
Add: 56
Final answer: 56
Yes, both equations are equivalent.
Answer:
<h2>10.3seconds</h2>
Step-by-step explanation:
Step one:
given data
acceleration,a= 10ft/sec^2
final velocity v= 70mph
first, let is convert mph to ft/sec
1mph is 1.46667 ft/sec
70 mph is x
cross multiply we have
x= 102.7ft/s
Step two:
we are using the first equation of motion
v=u+at
initial velocity u= 0m/s
102.7=0+10*t
102.7=10t
divide both sides by 10
t=10.3seconds
Let the number be x.
7x-x=42
6x=42
x=7
the number is 7
Answer:
9
Step-by-step explanation:
most accurate answer if tax was added it would be about 10 added to the fee when u do the math so the answer is 9
