Explanation:
Choice A combines to 11x since the 8+3 simplifies to 11.
Choice D is a very similar story. Think of having 8 boxes, which we denote in shorthand as 8x. Then adding on 3 more boxes leads to adding on 3x. Having 8 boxes plus another 3 boxes gives 8+3 = 11 boxes total. So that's why 8x+3x = 11x. Alternatively, we can factor out the x to say 8x+3x = (8+3)x.
This shows choices A,C, and D are equivalent expressions. Choice B is the odd one out.
Kaley's family drove to DisneyLand for spring break. Her mom and dad shared the driving duties for a total of 24 hours. Her mom drove 75 miles per hour, and her dad drove 60 miles per hour. If they drove a total of 1,710 miles, how many hours did each person drive for?
Answer:
Mom drove for 18 hours.
Dad drove for 6 hours.
Step-by-step explanation:
Given that:
Number of hours for the driving duty = 24 hours
Speed at which the mom drove = 75 miles per hour
Speed at which the dad drove = 60 miles per hour
Total distance driven by both of them = 1710 miles
To find:
Number of hours for which each person drive for ?
Solution:
Let number of hours driven by dad = [tex]x[/tex] hours
Let number of hours driven by mom = (24 - [tex]x[/tex]) hours
Let us have a look at the formula for Distance in terms of Speed and Time.
[tex]Distance = Speed \times Time[/tex]
Distance traveled by Mom = [tex]75 \times x =75x \ miles[/tex]
Distance traveled by dad = [tex]60(24-x) =144-60x[/tex] miles
As per question statement:
[tex]75x+1440-60x=1710\\\Rightarrow 15x=1710-1440\\\Rightarrow 15x = 270\\\Rightarrow x = 18\ hours[/tex]
So, Mom drove for 18 hours.
Dad drove for 6 hours.

A customer at a store paid $42 for 4 pairs of pants and 3 shirts. At the same store, a second customer paid $2 more for 1 pair of pants and 7 shirts. The price of each pair of pants is the same, and the price of each shirt is the same. Which system of equations can be used to find the price in dollars of each pair of pants, x, and each shirt, y?
Answer:
The system of Equations:
4x + 3y = 42
x + 7y = 44
Step-by-step explanation:
Let the price in dollars of
each pair of pants = x
each shirt = y
A customer at a store paid $42 for 4 pairs of pants and 3 shirts.
Hence:
4 × x + 3 × y = $42
4x + 3y = 42
At the same store, a second customer paid $2 more for 1 pair of pants and 7 shirts.
This means he, paid $42 +$2 = $44
Hence:
1 × x + 7 × y = 44
x + 7y = 44
The system of equations can be used to find the price in dollars of each pair of pants, x, and each shirt, y is
4x + 3y = 42.... Equation 1
x + 7y = 44..... Equation 2

Which street is parallel to 1st Ave?
A. 2nd Ave
B. Main Road
C. Central Ave
D. D Street
Answer:
i believe its the second ave
Parallel lines are those lines that are always the same distance apart and parallel lines do not intersect or meet each other.
The street that is parallel to 1st Ave is 2nd Ave.
What are parallel lines?Parallel lines are those lines that are always the same distance apart and parallel lines do not intersect or meet each other.
Example:
Line A and Line B have an angle of zero between each other.
This means Line A and Line B are parallel to each other.
We have,
Five streets:
1st ave
2nd ave
Central ave
D steet
Main road
Now,
Central Ave and the main road are parallel to each other.
1st Ave and 2nd Ave are parallel to each other.
D Street is perpendicular to 1st Ave and 2nd Ave.
Central Ave and Main Road are also perpendicular to 1st Ave and 2nd Ave.
We see that,
The street that is parallel to 1st Ave is 2nd Ave.
Thus,
The street that is parallel to 1st Ave is 2nd Ave.

196 divided by 3.5 show your work
The value of 196 ÷ 3.5 is 56
What is division?Division is the opposite of multiplication. If 3 groups of 4 make 12 in multiplication, 12 divided into 3 equal groups give 4 in each group in division. The main goal of dividing is to see how many equal groups are formed or how many are in each group when sharing fairly.
For example, if 50 apples are to be shared by 5 people , the number of apples allocated bto a person is 50/5 = 10 apples
196/3.5
to solve the we can multiply the numerator and denominator by 10 to make all whole number

It costs Widgeco $2,000 to purchase a machine that produces widgets and $2.75 to produce each widget. If widgets are sold for $4.99 each, which of these represents the profit, P(w), received when Widgeco sells w widgets?
Answer:
C. P(w) = 2.24w - 2000Step-by-step explanation:
Starting point is - $2000 as this is spending
Income is calculated as:
-2.75w + 4.99w = 2.24wSo the profit formula is:
P(w) = 2.24w - 2000Correct option is C from below answer choices
The options are:
A . P(w) = 2.24w + 2,000 B. P(w) = 7.74w + 2,000 C. P(w) = 2.24w – 2,000 D. P(w) = 7.74w – 2,000
