Answer:
a = 3.09 m/s^2
Step-by-step explanation:
v^2 = Vo^2 +2ax
v= final velocity
Vo = initial velocity
a = acceleration
x = distance
(-10.9)^2 = (-27.7)^2 + 2(a)(-105)
118.81 = 767.29 - 210a
-210a = -648.48
a = 3.09 m/s^2
[tex]( {v})^{2} - ({v(0)} \: )^{2} = 2 \times a \times ∆x[/tex]
[tex]( { - 10.9})^{2} - ({ - 27.7})^{2} = 2 \times a \times - 105 \\ [/tex]
[tex]118.81 - 767.29 = - 210 \times a[/tex]
[tex] - 648.48 = - 210 \times a[/tex]
Negatives simplified :
[tex]648.48 = 210 \times a[/tex]
Divided both sides by 210 :
[tex]a = \frac{648.48}{210} \\ [/tex]
[tex]a = 3.088 \: \: \frac{m}{ {s}^{2} } \\ [/tex]

Maggie's brother is 6 years younger than four times her age. The sum of their ages is 69.
How old is Maggie?
Answers
Answer:
15
Step-by-step explanation:
If Maggies age is, for example, x, we can say that her brothers age is 4x-6. We know from the problem that Maggies age (x) plus her bothers age, (4x-6) is 69. So,
4x-6+x=69
5x-6=69
5x=75
x=15
So, Maggie is 15.
Answer: Maggie is 15 years old
Step-by-step explanation:
69 = (4m - 6) + m --- get an equation
69 - m = 4m - 6 --- lets subtract m from both sides first
75 - m = 4m --- add 6 on both sides
75 = 5m --- add m on both sides
15 = m --- divide by 5 on both sides
m = 15, so Maggie is 15 years old
Let's check:
69 = (4(15)-6) +15
69 = (60 - 6) + 15
69 = 54 + 15
69 = 69
The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Josh is comparing the cost of having his car wash plus filling up his tank with gas at each business. How many gallons of gas would he need to purchase for the cost to be the same at each car wash?
Answers
Answer:
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash
Step-by-step explanation:
We need to model both car wash's costs. The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. If x is the number of gallons of unleaded gasoline. the total charges of this store are:
C1=15+2.5*x
The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Following the same procedure, their costs are:
C2=10+2.75*x
Josh wants to know how many gallons of gas will make both businesses charge the same. Equating both equations:
15+2.5*x=10+2.75*x
Simplifying:
-0.25x=-5
Solving:
x=-5/(-0.25)=20
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash

The sum of 4 times a number and 7 equals 5.
Use the variable w for the unknown number.
Answers
Answer:
4w +7 = 5
Step-by-step explanation:
Have a nice day.
Answer:
4w + 7 = 5
Step-by-step explanation:
"sum" means addition (+), so we're to add two items:
item 1 to be added
"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).
Therefore, 4 x w = 4w
item 2 to be added
This is the number 7
The sum
4w + 7
Now, the sum, equals(=) the number 5, therefore answer:
4w + 7 = 5

Fun Zone charges an entrance fee
of $4.50 and $0.65 per ticket. Happy
Town charges $0.40 per ticket and a
$5.00 entrance fee. How many
tickets must be purchased in order
for the total to be the same at both
Fun Zone and Happy Town?
Answers
Answer:
2 tickets
Step-by-step explanation:
To be the same they must equal each other.
4.50 + 0.65x = 0.40x + 5
isolate the variable
subtract 4.50 from both sides
0.65x = 0.40x + 0.50
subtract 0.40x from both sides
0.25x = 0.50
divide both sides by 0.25
x = 0.50 ÷ 0.25
x = 2
