Answer:
Alyssa’s lemonade recipe
Step-by-step explanation:
→ Work out how much lemons is needed per gallon for Alyssa’s lemonade recipe
9 lemons = 2.5 gallons
(÷ 2.5) = (÷ 2.5)
3.6 lemons = 1 gallon
→ Work out how much lemons is needed per gallon for Brian’s lemonade recipe
12 lemons = 4 gallons of water
(÷ 4) = (÷ 4)
3 lemons = 1 gallon of water
→ Now compare
Alyssa’s lemonade recipe ⇒ 3.6 lemons = 1 gallon
Brian’s lemonade recipe ⇒ 3 lemons = 1 gallon of water
Brian's lemonade recipe requires more water.
Alyssa uses 10 gallons of water for 36 lemons. Brian uses 12 gallons of water for 36 lemons. Therefore Brian's lemonade recipe requires more water.
Can someone help me? Kendall owns 39 CD’S, and he buys a new one every week. Raymond only owns 15 CD’S but he buys 3 new ones each week. How many weeks will it be before Raymond owns as many CD’S as Kendall?
Answer:
7 weeksStep-by-step explanation:
Let the number of weeks be x
Then Kendal's CD's
39 + xRaymond's CD's
15 + 3xTime when they have equal CD's
39 + x = 15 + 3x3x - x = 39 - 152x = 14x = 7 weeksAnswer:
That is wrong... 7 is not the answer

What is the solution to this equation? 4- 5k = -21
a.5
b.21
c.17 over 5
4 over 5
Answer:
k = 5
Step-by-step explanation:
4 - 5k = -21
Transpose and subtract 4 from both sides:
4 - 4 - 5k = -21 -4
-5k = -25
Divide both sides by -5
-5k/-5 = -25/-5
k = 5
Sarita showed the steps to solving the equation. 5 (x minus 3) + 7 (x + 4) = 73 Steps Sarita's Solution Sarita's Verification 1 5 x minus 15 + 7 x + 28 = 73 5 (5 minus 3) + 7 (5 + 4) = 73. 5 (negative 2) + 7 (9) = 73. Negative 10 + 63 = 73. 53 not-equal-to 73. 2 (5 + 7) x + (negative 15 + 28) = 73 3 12 x + 13 = 73 4 12 x + 60 5 x = 5 When Sarita tried to verify her answer, she found it was wrong. Which explains her mistake?
Answer:
Sarita’s solution is correct. She made an error in her verification. Sarita was supposed to add the 5 and 7 in the first step.
Step-by-step explanation:
Given the following equation:
The steps to solve it are:
5(x-3)+7(x+4)-73
1. Apply the Distributive property:
5x-15+7x+28=73
2. Add the like terms:
12x+13=73
3. Subtract5 13 from both sides of the equation:
12x+13-(13)=73-(13
12x=60
4. Divide both sides of the equation by 12:
12r/12 = 60/12
x = 5
To verify it, let's substitute into the equation:
5(5-3)+7(5+4)=73
Evaluating, we get:
5(2)+7(9)=73
10+63=73
73=73
Based on this, we can determine that Sarita's solution is correct, but she made an error in her verification (Observe that 5-3 is not equal to -2 )
Answer:
A. Sarita’s solution is correct. She made an error in her verification.

What is 5x-7(x+1)=9
Thanks for the help
Answer:
x = -8
Step-by-step explanation:
Step 1: Write equation
5x - 7(x + 1) = 9
Step 2: Solve for x
Distribute -7: 5x - 7x - 7 = 9Combine like terms: -2x - 7 = 9Add 7 to both sides: -2x = 16Divide both sides by -2: x = -8Step 3: Check
Plug in x to verify it's a solution.
5(-8) - 7(-8 + 1) = 9
-40 - 7(-7) = 9
-40 + 49 = 9
9 = 9

If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?
Answer:
36.16 miles
Step-by-step explanation:
A recycling truck begins its weekly route at the recycling plant at point A, as pictured on the coordinate plane below. It travels from point A to point B, then points C, D, and E, respectively, before returning to the recycling plant at point A at the end of the day. The truck’s route is illustrated on the coordinate plane below. If each unit on the coordinate plane represents one mile, what is the total distance the truck travels on its route?
Answer:
The distance between two points X([tex]x_1,y_1[/tex]) and Y[tex](x_2,y_2)[/tex] is given as:
[tex]|XY|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
From the image attached, the coordinates of the plane are:
A(-1, -1), B(1, -1), C(5, 2), D(0, 13), E(-5, 2).
The lengths are:
[tex]|AB|=\sqrt{(1-(-1))^2+(-1-(-1))^2}=2\ units\\ \\|BC|=\sqrt{(5-1)^2+(2-(-1))^2}=5\ units\\\\|CD|=\sqrt{(0-5)^2+(13-2)^2}=12.08\ units\\\\|DE|=\sqrt{(-5-0)^2+(2-13)^2}=12.08\ units\\\\|AE|=\sqrt{(-5-(-1))^2+(2-(-1))^2}=5\ units[/tex]
But 1 mile = 1 unit
Total distance = |AB| + |BC| + |CD| + |DE| + |AE| = 2 + 5 + 12.08 + 12.08 + 5 = 36.16 miles
Star A is about 3.4 x10^18 miles from earth. star B is 6.8 x 10^16 miles from earth.Star A is how many times as far from Earth as Star B? I
Answer: It's 50
Step-by-step explanation:
3.4 divided by 6.8 is 0.5 and 18-16 (the exponents) is 2. since ur dividing your subtracting the exponents. so then u get 0.5*10^2 but it cant be lower than 1 so u move the decimal in 0.5 one space to the right which then leads you to get 5*10^1 or 5*10 which is 50.

Where is the shading in the graph of the quadratic inequality y > -22 + 6x + 3? Why?
Answer:
Check Graph below
Step-by-step explanation:
y > -22 + 6x + 3
Add -22 and 3.
y > 6x - 19
Use the slope-intercept form to find the slope and y-intercept.
Slope: 6
y-intercept: (0,-19)
Graph a dashed line, then shade the area above the boundary line since y is greater than 6x − 19 .
y > 6x - 19

There are 6 m spaces help
Answer with step-by-step explanation:
If the comparison is 5 cm:6 m, then the numbers would be 5:600. If so, we have to multiply each of the dimensions by 5/600.
7.5 cm = 1/16 m
9 cm = 3/40 m
6 cm = 1/20 m
3.5 cm = 7/240 m

Answer:
[tex]\huge\boxed{66.42 \textdegree}[/tex]
Step-by-step explanation:
In order to solve for this missing angle, we can use trigonometry.
With angle B, we only have two sides: the adjacent of the angle and the hypotenuse of the angle. The adjacent side is the one laying directly next to the angle that isn't the hypotenuse.
Using SOH CAH TOA, we can see that the correct trig function for this would be cos because of CAH (Cosine = Adjacent over Hypotenuse)
Since we know the length of the sides but we don't know the angle, we are going to use inverse trig.
The adjacent side over our hypotenuse will be [tex]\frac{2}{5}[/tex] since 2 is the length of the adjacent and 5 is the length of the hypotenuse.
We know have the equation [tex]cos^{-1}(B) = \frac{2}{5}[/tex].
We now find what [tex]\frac{2}{5}[/tex] is (0.4) and find the inverse cosine of it. We can do this by plugging it into a calculator.
When we do this, we get the number [tex]66.42182152[/tex] etc. Rounding to the nearest hundredth gets us 66.42.
Hope this helped!
What is the ratio AC: CB?
Answer:
how do we find this out
Step-by-step explanation:
Which rule describes the transformation?
O(x, y) - (x, y)
O (x,y) - (y,x)
O (x,y) - (-x, -y)
O (x, y) - (y, -x)
The rule that describes the transformation is (x, y) → (-x, -y).
Option C is the correct answer.
We have,
From the graph,
A = (-1, -1)
B = (1, -1)
C = (0, -4)
And,
A' = (1, 1)
B' = (-1, 1)
C = (0, 4)
Now,
If we use transformation:
(x, y) → (-x, -y) on each coordinate of A, B, and C.
We get,
A' = (1, 1)
B' = (-1, 1)
C = (0, 4)
Thus,
The rule that describes the transformation is (x, y) → (-x, -y).
