Answer:
Y=25-4x
Y means the distance Jordan still has to walk after x hours
Step-by-step explanation:
Answer:
y = 25 - 4*x
The y-intercept represents the total distance Jordan has to walk
Step-by-step explanation:
By Definition, speed = distance/time. We are interested in distance, then:
distance = speed*time
Calling x the hours of walking, and knowing that his speed is 4 mi/h, then:
distance = 4*x
The trail length is 25 miles, so if he walked 1 mile, 25 - 1 = 24 miles are left, in general:
y = 25 - 4*x
where y is the distance Jordan still has to walk.
The y-intercept is found replacing with x = 0, then:
y = 25 - 4*0
y = 25
which represents the total distance Jordan has to walk
2x -1 + x +1 = 180
PLEASE SOLVE CORRECTLY
Answer:
x = 60
Step-by-step explanation:
Combine like terms on the left side of the equation: 2x + x = 3x; -1 + 1 = 0 so the total for the left side is just 3x. Now compare it to the full equation that you have left now, 3x = 180 now do 180/3 = 60

Sarah is making strings of beads in the first string she uses 3 beads and she triples the number of beads in each of the next strings identify the number of beads she uses in 5th string.
Answer:
She uses 243 beads for the 5th string.
Step-by-step explanation:
In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:
The second uses 9, 3 * 3 = 9
The third uses 27, 9 * 3 = 27
The fourth uses 81, 27 * 3 = 81
And the 5th uses 243, 81 * 3 = 243.

nalia worked 3.5 hours more than lisa together they worked a total of 18 hours lisa worked h hours
Answer:
7.25 and 10.75 Hours
Step-by-step explanation:
Total hours Nalia and Lisa worked = 18 Hours
Nalia worked 3.5 hours then Lisa which is [tex]h[/tex] hours
⇒[tex]h + (h + 3.5) = 18[/tex]
[tex]2h + 3.5 = 18\\2h = 18 - 3.5\\2h = 14.5\\h = \frac{14.5}{2} \\h = 7.25[/tex]

Simplify the expression -3/8 -1/10
The simplified expression is -11/40.
The expression -3/8 - 1/10 can be simplified by following these steps:
1. Find a common denominator for the two fractions. The smallest number that both 8 and 10 can divide into is 40.
2. Rewrite the fractions using the common denominator.
-3/8 = -15/40
-1/10 = -4/40
3. Subtract the rewritten fractions.
-15/40 - (-4/40) = -15/40 + 4/40 = -11/40

Solve y = x + 4 for x.

x = −y + 4
x = −y − 4
Answer:
x=y-4
Step-by-step explanation:
y=x+4
-4
y-4=x
Answer:
Option A.
Step-by-step explanation:
y = x + 4
As we know if we perform a similar operation on both the sides of the equation it doesn't affect the parent equation.
So we subtract 4 on both sides of the equation
y - 4 = (x + 4) - 4
x = y - 4
Therefore, option A. will be the answer.

In a community garden (shown to the right) you want to plant and fence in a vegetable garden that is adjacent to your friend’s garden. You have at most 54 ft of fence, and the fence must surround all four sides of your garden. What are the possible lengths of your garden
To find the possible lengths of the garden, use the perimeter formula and solve the inequality x <= 27 ft.
Explanation:To find the possible lengths of your garden, you need to determine the perimeter of the garden. Since you have at most 54 ft of fence, the perimeter must be less than or equal to 54 ft.
Let's assume the length of your garden is 'x', then the width would be (54 - 2x)/2.
The perimeter formula is P = 2L + 2W, so substituting the values we have, 2x + 2[(54 - 2x)/2] <= 54.
Simplifying this inequality, we get x + 54 - 2x <= 54. Solving for 'x', we get x <= 27.
Therefore, the possible lengths of your garden are any value less than or equal to 27 ft.

I am a pattern block that has 2 fewer sides than a hexagon. I have 2 pairs of parallel sides a 4 right angles. Which shape am I
The shape described is a square, having four sides, two pairs of parallel sides, and four right angles, making it two sides fewer than a hexagon.
The shape you are referring to is one with four sides, two pairs of parallel sides, and four right angles. A hexagon has six sides, so a shape with two fewer sides would have four sides. This description matches that of a rectangle. However, since all angles are right angles, which is 90 degrees, this particular rectangle is also a square. Therefore, the pattern block shape you are asking about is a square, which fits the criteria of having two fewer sides than a hexagon, two pairs of parallel sides, and four right angles.

The decimal equivalent of 4 thousands, 9 hundreds, 2 tens, and 6 ones is 4926. This is calculated by adding the value of each quantity: 4000 (from the 4 thousands), 900 (from the 9 hundreds), 20 (from the 2 tens), and 6 (from the 6 ones)
Explanation:The question is asking for the decimal equivalent of the quantity represented by 4 thousands, 9 hundreds, 2 tens, and 6 ones. To determine the answer, you would simply total the value of each quantity: 4 thousands equals 4000, 9 hundreds equals 900, 2 tens equals 20, and 6 ones equals 6. When you add these values together (4000 + 900 + 20 + 6), you get the total value of 4926 which is the decimal equivalent that we are looking for.

b. Next week, Mr. Lee will double the number of boxes he orders. Write a new expression to represent the number of oranges in next week’s order.
c. Evaluate your expression from Part (b) to find the total number of oranges ordered in both weeks.
Answer:
a)480
b)960
c)1440
Step-by-step explanation:
We are given the following information:
Number of oranges in a box = 24
a)Boxes ordered by Lee for his store = 8
Number of boxes ordered by Lee for his restaurant = 12
Total number of oranges ordered = Total number of boxes ordered × Number of oranges in 1 box
[tex]= (8+12)\times 24 = 20\times 24 = 480[/tex]
b) Now Mr. Lee doubled his order for next week.
Boxes ordered by Lee for his store = 16
Number of boxes ordered by Lee for his restaurant = 24
Total number of oranges ordered = Total number of boxes ordered × Number of oranges in 1 box
[tex]= (16+24)\times 24 = 40\times 24 = 960[/tex]
c) Total number of oranges ordered =
[tex](20\times 24) + (40\times 24) = (20+40)\times 24 = 1440[/tex]
Therefore, total 1440 oranges were ordered by Mr. Lee.
