Step-by-step explanation:
The total distance did Aaron walk today is 4.70 miles.
It is required to find the total distance.
What is distance?
The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Given :
Aaron walks 2 1/8 miles to his friends.
He walk 5/6 miles to the park.
Again he walks 1 3/4 miles to get back home.
Total distance=
2 1/8 miles+5/6 miles+ 1 3/4 miles
=17/8+5/6+7/4
=4.70 miles
Therefore, the total distance did Aaron walk today is 4.70 miles.

Wha is 4/5 = 28/x oh and 2 ways I can writ it
Answer:
x = 35
Step-by-step explanation:
x-8/2=4 please help me asap this assignment is due in and hour! and please teach me how to do it! 10 points!!
Answer:
x = 8
Step-by-step explanation:
x - 8/2 = 4
Follow your order of operations and divide first.
8/2 is 4
x- 4 = 4
Next, isolate the variable by using the additive property of equality.
x - 4 + 4 = 4 + 4
x = 8
Answer:
ok so u do the opposite of 8/2 so do 8*2 which is 16 then add the answer which is 4 which equals 20 so 20- 8/2=4, 20-16=4

6x + 3 (2x) - 7 - 2³ Please include th steps to solving it.
Answer:
24x-15
Step-by-step explanation:
Let's do this together with a step-by-step explanation!
First we need to make sure we remember that there are appropriate ways on how to solve these. LIKE PEMDAS.
6x + 3 (2x) - 7 - 2³
Let's multiply the 3 and 2x together.
6x + 6x - 7 - 2³
Now let's do the exponent
6x + 6x - 7 - 8
Now let's add everything together! But remember only common variables can be added together.
24x - 15 is the answer.
You can no longer break anything down.
I really hope this helped you!
Answer:
12x - 15
Step-by-step explanation:
so you would have to do the order of operations. so your exponent would be first. so 2×2×2=8.
6x + 3 (2x) -7 + 8
Now you can look at your parentacese which is (2x) so you need to do 3(2x) which gets you 6x.
6x + 6x -7 + 8
So you need to combine like terms.
so starting with the x
6x + 6x = 12x
Now your equation looks like this
12x + -7 +8
now you need to add like terms. (numbers)
-7 -8
so your answer is
12x -15

can someone show me the answer + how they got there? (x+4)(x-1)
Answer:
x^2+3x-4
Step-by-step explanation:
x * x - x + 4x - 4
x^2 - x + 4x - 4
x^2 + 3x - 4
=============================================
Explanation:
You can use the FOIL rule to expand out (x+4)(x-1), but here's another way you could do it.
Let y = x+4
This means we replace (x+4) with y to get y(x-1)
Distribute the y term through to get yx-y which can be written as x(y) - 1(y)
After this, replace y with x+4 getting x(x+4)-1(x+4)
Distribute a second time and simplify like so
x(x+4)-1(x+4)
x^2+4x-1x-4
x^2+3x-4

O E
E. 35º, 70°
Answer:
E. 35°, 70°
Step-by-step explanation:
Sum of angles add up to 180° in every triangle.
Step 1: Set up equation
a + 2a + 75 = 180
Step 2: Combine like terms
3a + 75 = 180
Step 3: Subtract 75 on both sides
3a = 105
Step 4: Divide both sides by 3
a = 35
So 1 angle is 35°
Step 5: Plug in a to find last angle
2(35) = 70°

Nora took 10 bottles of water to a picnic. Of these bottles of water, she and her friends opened a certain number of bottles, b. What expression can be used to determine the number of unopened bottles at the end of the picnic?
Answer:
10 - B = U
Step-by-step explanation:
U stands for the unopened bottles
for example if they opened 3 bottles it would be 10 - 3 = U (unopened bottles)
The value of U is 7 because the 10 bottles of water minus the 3 bottles they opened it would equal 7.
therefore the equation 10 - B = U shows the amount of unopened bottles
100 trout are seeded into a lake. Absent constraint, their population will grow by 70% a year. The lake can sustain a maximum of 2000 trout. How many trout will be in the lake after 2 years.
After 2 years, the population of trout in the lake will be 2000 trout.
Given:
Initial population = 100
Growth rate = 70%
Time= 2 years
After the first year:
Population after 1 year = Initial population + (70% of the initial population)
= 100 + (0.7 * 100)
= 100 + 70
= 170 trout
After the second year:
Population after 2 years = Population after 1 year + (70% of the population after 1 year)
= 170 + (0.7 * 170)
= 170 + 119
= 289 trout
Since the calculated population exceeds this limit, the population will be limited to the maximum capacity of 2000 trout.
Therefore, the population of trout in the lake will be 2000 trout.

#SPJ12
carries family broke a package of graham crackers into 32 pieces. carries two brothers each ate 1/8 of the pieces and the rest of the family ate 7/16 of the pieces.
carries two brothers each ate ____ pieces
the rest of carries family ate ____ pieces
there were ____ pieces remaining
Answer:
Carrie's two brothers each ate 4 pieces, and the rest of the family ate 14 pieces, there were 10 pieces left.
Step-by-step explanation:
First, change all of the fraction's denominators into 32:
1/8 = 4/32
7/16 = 14/32
This gives us the answer to the first two questions.
Then add up the amount of pieces each person ate. Carrie has two brothers, so we double 4/32, which gives us 8/32. 8/32 + 14/32 = 22/32.
32 - 22 = 10, so there are 10 pieces remaining.
Hope this helps!
Answer:
Carries two brothers ate 4 pieces.
The rest of Carries family ate 14 pieces.
There were 14 pieces remaining.
Step-by-step explanation:
To find out how much the brothers ate you can divide 32 by 8 to get 4. For the family you can turn 7/16 into 32nds
16 x 2 = 32 and 7 x 2 = 14
so the family ate 14 pieces. Add 14 + 4= 18 so that's how much they all ate in total then 32-18 = 14. That means 14 pieces are left.
Hope that helps and have a great day!

Answer:
The product 12 × 15 in friendlier numbers is (10 + 2) × (10 + 5) = 180
Step-by-step explanation:
The parameter given are;
To 12 × 15 by changing the numbers into friendlier numbers
The product in 12 × 15 written with friendlier numbers (or in a simplified format can be given as follows;
12 × 15 = (10 + 2) × (10 + 5)
Which gives;
(10 + 2) × (10 + 5) = 10² + 10 × 5 + 2 × 10 + 2 × 5
From which we have;
10² + 10 × 5 + 2 × 10 + 2 × 5 = 100 + 50 + 20 + 10 = 180
Therefore;
12 × 15 = 180.

miles
Answer:
7.7
Step-by-step explanation:
trust me, I solved it out
Answer: The distance between port 3 to port 1 is 7.7 miles.
A rough sketch is attached.
The angle between 3.5 and 6 is = (90 + 15) = 105 degrees.
We will need the law of cosine.
So the distance between port 3 to port 1 is:
[tex]\sqrt{3.5^{2}+6^{2}-2\left(3.5\right)\left(6\right)\cos\left(105\right)}=7.68897911912=7.7[/tex].

What is the image point of (6,1) after a translation left 5 units and down 1 unit?
Answer:
(1, 0 )
Step-by-step explanation:
A translation of 5 units left means subtract 5 from the x- coordinate
A translation of 1 unit down means subtract 1 from the y- coordinate, thus
(6, 1 ) → (6 - 5, 1 - 1 ) → (1, 0 )

if the width is 8 less than the length of a rectangle and the perimeter is 48 find the width
Answer:
Widyh = 8 units
Step-by-step explanation:
Perimeter = 2/width+length)
then:
48 = 2(W+L)
W = L-8
W = Width
L = Length
then:
48 = 2((L-8)+L)
48 = 2(2L88)
48 = 2*2L - 2*8
48 = 4L - 16
48 + 16 = 4L
64 = 4L
L = 64/4
L = 16
W = L-8
W = 16-8
W = 8
Check:
48 = 2(16+8)
48 = 2*24

Who ran the fastest? Explain how this is shown on the graph and in the tables?
Answer:
1) Please find attached the distance and speed time graphs
2) Please find attached the distance time tables
3) The fastest runner is Jason, as shown by the topmost line in the graphs
4) On the tables Jason is seen to have covered 400 meters in one minute, while Patti covered 300 meters and Quincy covered in the same one minute time interval
Step-by-step explanation:
The given speed of the runners are;
The rate at which Patti ran = 300 meters in 60 seconds
The rate at which Jason ran = 500 meters in 1.25 minutes
The rate at which Quincy ran = 600 meters in 2 minutes and 30 seconds
The formula for speed is given as follows;
Speed = Distance ran/(Time to cover the distance)
Therefore, the speed of each of the runners are;
Patti's speed = 300 m/(60 seconds) = 300 m/(1 minute) = 300 m/min
Jason's speed = 500 m/(1.25 minute) = 400 m/min
Quincy's speed = 600 m/(2 minutes and 30 seconds) = 600 m/(2.5 minutes)
∴ Quincy's speed = 240 m/min
Therefore, we have
1) The distance and speed time graphs are attached
2) The distance time tables are attached
3) The fastest runner is Jason, as shown by the topmost line in the graphs
4) The fastest runner is Jason as seen by the covered distance of 400 meters in one minute.
