Ms. Leaman spends $2.00 a day on her morning coffee. How much does she spend in one week? Draw a double number line.
Answer:
She spends $2 a day, and there are 7 days a week. So, you'd multiply the amount which is 2 by the 7 days.
The amount she spends in one week is $14! I don't know how to add a double number line, so you do that part!

Liza needs help to solve this linear equation.
4(x – 5) + 2x = 9x – 2(4 + 2x)
She has completed two steps, but now she’s stuck. Examine her work.
1. 4x - 20 + 2x = 9x - 8 - 4x
2. 6x - 20 = 5x - 8
What could be the next step? Select all that apply.
Add 8 to both sides.
Add 5x to both sides.
Subtract 6x from both sides.
Subtract 20 from both sides.
Divide both sides by –8.
Divide both sides by –20.
Answer: It is A and C:
A: Add 8 to both sides
C: Subtract 6x from both sides

This question is not correctly written
Complete Question
A 6-ft-tall person walks away from a 11-ft lamppost at a constant rate of 3.3 ft/sec. What is the rate that the tip of the person's shadow moves away from the lamppost when the person is 11 ft away from the lampost?
Answer:
7.26ft/s
Step-by-step explanation:
A 6-ft-tall person walks away from a 11-ft lamppost at a constant rate of 3.3 ft/sec. What is the rate that the tip of the person's shadow moves away from the lamppost when the person is 11 ft away from the lampost?
Let x = distance of person to the tip of the lamp post
= 6/x = 11/d
Cross Multiply
6d = 11 x....... Equation 1
The constant rate of the person = 3.3 ft/s
= Distance of the person to the pole = Speed × time
= 3.3 × t
d = 3.3t
x = d - 3.3t
Substitute d - 3.3t for x in Equation 1
6d = 11x
6d = 11(d - 3.3t)
6d = 11d - 36.3t
36.3t = 11d - 6d
36.3t = 5d
d = 36.3/5
d = 7.26 ft/s

Write the equation of the graph in its final position.
The graph of y = ex is translated 7 units to the right and then 5 units upward.
what did you guys get?
The new function after the transformation becomes as y = eˣ⁻⁷ + 5. The correct option is (d).
How to transform a graph of the function?The graph of a function can be transformed by either shifting it in the right, left, up or down.
When the transformation is rightwards, the function becomes as f(x - a).
For left shifting it is f(x + a).
And, for up and down shift it is a + f(x) and a - f(x) respectively.
Given that,
The graph of y = eˣ is translated 7 units to the right and 5 units upward.
According to the rule of transformation for a graph, when a function is shifted righwards, it becomes as f(x - a) and when it is shifted upwards it becomes a + f(x).
Apply the above mentioned rule for the given function to obtain,
y = eˣ⁻⁷ + 5
Hence, the function resulting after being shifted 7 units rightwards and 5 units upwards is y = eˣ⁻⁷ + 5.

Devante invests $4000 in two different accounts. The first account paid 6 %, the second account paid 11 % in interest. At the end of the first year he had earned $320 in interest. How much was in each account?
$
at 6 %
$
at 11 %
Answer:
y=1600
x=2400
Step-by-step explanation:
x+y=4000
solve for a variable
x=4000-y
plug this into .06x+.11y=320 (the interest from account 1 + account 2 must equal 320)
.06(4000-y)+.11y=320
240-.06y+.11y=320
minus 240 both sides
-.06y+.11y=80
combine terms
.05y=80
divide by .05
y=1600
to find x you subtract 1600 from 4000 to get 2400
remember, your equation must be x+y=4000
x+1600=4000
-1600
x=2400

The length of a rectangle is 3 m more than 5 times the width. The perimeter is 126
m.
What is the length?
Answer:
53m
Step-by-step explanation:
Let x = the width
Let y = the length
5x + 3 = y
2x + 2y = 126
Plug in 5x + 3 for y in the second equation
2x + 2(5x + 3) = 126
Distribute the 2
2x + 10x + 6 = 126
Combine like terms
12x + 6 = 126
Subtract 6 from both sides
12x = 120
Divide both sides by 12
[tex] \frac{12x}{12} = \frac{120}{12} [/tex]
x = 10
Remember x = width. You are looking for length.
y = 5x + 3
y = 5(10) + 3
y = 50 + 3
y = 53

Step-by-step explanation:
Luke and Liam found an old castle on a recent hike.
15°
125
The sign said the tower was 30 meters high. Because of social distancing, Luke and Liam stood
meters apart while looking at the top of the castle tower.
Round to the nearest meter.
Answer:
48 meters
Step-by-step explanation:
First, use trigonometric ratios formula to find the distance of each of them from the tower. The difference between their distance from the tower will give you the distance they stood apart from each other.
Distance of the first person from the Tower with am angle of elevation of 25°:
Height of the tower = 30 meters (opposite side)
Distance from the tower = x (adjacent side)
[tex] tan(25) = \frac{opp}{adjacent} [/tex]
[tex] tan(25) = \frac{30}{x} [/tex]
Multiply both sides by x
[tex] tan(25)*x = 30 [/tex]
Divide both sides by tan(25)
[tex] x = \frac{30}{tan(25)} [/tex]
[tex] x = 64 m [/tex] (nearest whole number)
Distance of the second person from the Tower with am angle of elevation of 15°:
Height of the tower = 30 meters (opposite side)
Distance from the tower = x (adjacent side)
[tex] tan(15) = \frac{opp}{adjacent} [/tex]
[tex] tan(15) = \frac{30}{x} [/tex]
Multiply both sides by x
[tex] tan(15)*x = 30 [/tex]
Divide both sides by tan(15)
[tex] x = \frac{30}{tan(15)} [/tex]
[tex] x = 112 m [/tex] (nearest whole number)
Distance between both of them = 112 - 64 = 48 meters

Tanya has 44 quarters and dimes worth$8.30. how many of each type of coin does she have
Tanya has 26 quarters and 18 dimes.
Given that Tanya has 44 quarters and dimes which worth $8.30, we need to find the number of each coin type,
To find the same we will use the concept of system of Linear equations,
Let's solve this problem step by step.
Let's assume Tanya has x quarters and y dimes.
The value of x quarters is 25x cents.
The value of y dimes is 10y cents.
According to the given information, the total value of the quarters and dimes is $8.30, which is equivalent to 830 cents. So we have the equation:
25x + 10y = 830 ...........(Equation 1)
Tanya has 44 coins in total:
x + y = 44 ...........(Equation 2)
Now, we can solve this system of equations (Equation 1 and Equation 2) to find the values of x and y.
Multiplying Equation 2 by 25, we get:
25x + 25y = 1100 ...........(Equation 3)
Subtracting Equation 3 from Equation 1, we eliminate the x term:
25x + 10y - (25x + 25y) = 830 - 1100
-15y = -270
Dividing both sides by -15, we get:
y = (-270)/(-15) = 18
Substituting the value of y back into Equation 2, we can find x:
x + 18 = 44
x = 44 - 18 = 26
Therefore, Tanya has 26 quarters and 18 dimes.
