Answer:
Juliet collect 35 cans
Step-by-step explanation:
Let
x ------> number of cans collected by Juliet
y ------> number of cans collected by Rosana
z ------> number of cans collected by Santiago
we know that
-----> equation A
----> ----> equation B
-----> equation C
Substitute equation B and equation C in equation A and solve for x
Combine like terms
Adds 10 both sides
Divide by 4 both sides
therefore
Juliet collect 35 cans
Answer:
see explanation
Step-by-step explanation:
Given
+ 2c + 11
= - + 2c + 11
= 3c - 1 + 2c + 11
= 5c + 10
(b)
We have the expression
5c + 10 ← factor out 5 from each term
= 5(c + 2)
Each time in the sequence, 20 is subtracted.
The answer is they all have a factor of 9
Givens
a = 4.4 m/s^2 This is an acceleration and is positive.
vi = 10.2 m/s
t = 4.2 seconds
vf = ????? The cruising speed in this case is vf.
Formula
a = (vf - vi)/t Notice the 3 givens and what you seek determine the formula
Solve
4.4 m/s^2 = (vf - 10.2)/4.2 Multiply both sides by 4.2
4.4 * 4.2 = vf - 10.2
18.48 = vf - 10.2 Add 10.2 to both sides
18.48 + 10.2 = vf 8.28 is the second best answer.
28.68 = vf This is your cruising speed.
