Step-by-step explanation: 7 miles: 3/4 hour, 9/8 miles: 5/6 hour, and 4 miles: 3 and 1/3 hour.
hope this helps !! <3
The ratios that have a unit rate is 9/8 miles:5/6hours and 7miles: 3/4 hours
Unit rate is the ratio of the distance travelled o the time taken.
For us to know which of the ratios has a unit rate greater than 1, we need to divide the distance by the time as shown;
If distance = 9/8 miles and time = 5/6 hours
[tex]Unit \ rate =\frac{(9/8)}{(5/6)}\\Unit \ rate =\frac{9}{8} \times \frac{6}{5}\\Unit \ rate = \frac{54}{40} \\Unit \ rate =1.35 miles/hour[/tex]
Hence the ratio that has a unit rate is 9/8 miles:5/6hours
If distance = 7 miles and time = 3/4 hours
[tex]Unit \ rate =\frac{7}{(3/4)}\\Unit \ rate =\7 \times \frac{4}{3}\\Unit \ rate = \frac{28}{3} \\Unit \ rate = 9.33miles/hour[/tex]
Hence the ratio that has a unit rate is 7 miles:3/4hours

In the equation 6x - 2 = -4x + 2, Spencer claims that the

the first step is to subtract 6x from both sides. Who is
correct? Explain.
Answers
Answer:
Spencer is correct
Step-by-step explanation:
Because adding 4x to each side will bring both numbers to a positive and that makes it easier to get the answer
Answer:
Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.

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
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
1. A specialty shop sells gift baskets that contain three different types of
candles: tapers, pillars, and jar candles. Tapers cost $1 each, pillars cost $4
each, and jar candles cost $6 each. Each basket contains 8 candles costing
a total of $24, and the number of tapers is equal to the number of pillars
and jar candles combined. Which system of equations represents the
situation, where t is the number of tapers, p is the number of pillars, and jis
the number of jar candles? *
Answers
Answer:
Option (B)
Step-by-step explanation:
Let the number of tapers in the basket = t
Number of pillars = p
And the number of jar candles = j
Tapers cost = $1 each
Jar candles cost = $6 each
Pillars cost = $ 4
Total number of candles in the basket = 8
Therefore, equation will be,
p + t + j = 8 -----(1)
Cost of the candles in the basket = $24
$1t + $4p + $6j = $24
t + 4p + 6j = 24 -------(2)
Since number of tapers is equal to the number of pillars and jar candles combined,
t = p + j
t - p - j = 0 ------(3)
Therefore, Option (B) is the answer.

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
