Evaluate the expression when x = 4 and y = 1.
2(8 - y)
Consider the pairs of ratios given in the first column and determine whether or not the ratios form a proportion.
Answer:
Options 1 and 2 are proportional, the last one isn't.
Step-by-step explanation:
I found option 1 by dividing 8 / 1, then multiplying it by 2 to see if I get 16. I got 16 so it's proportional.
I found the 2nd option by dividing 9 / 4, and then multiplying it by 8 to see if I get 18. I got 18 so it's proportional.
I found option 3 by dividing 16 / 6, and then multiplying it by 4 to see if I get 10. I didn't 10, so it isn't proportional.
The square root of 72?
Answer:
6√2
Step-by-step explanation:
The square root of 72 is an irrational number, so we can't make the square root of 72 into an accurate decimal form. However, we can simplify it!
The factors that have the greatest square are 2 and 36.[tex]\sqrt{72} = \sqrt{36} * \sqrt{2}[/tex] [tex]\sqrt{36} *\sqrt{2} = 6\sqrt{2}[/tex]Therefore, the answer is 6√2.
Answer:
8.48 or [tex]\sqrt[6]{2}[/tex] (simplified)
Step-by-step explanation:
When we first try solving the square root of 72, we get [tex]\sqrt[6]{2}[/tex].
Next we simplify that square root, and get 8.48528 or just 8.48.
Separate your square root base into pairs.
Find the largest square that divides into the first number or pair.
Subtract the square from the first number or pair.
Drop down the next pair
Multiply the first digit of the square by two.
Set up the next factor equation.
Find the missing number so that the equation has infinitely many solutions.

helpppp !!!!!!! pls and ty alot
===================================================
Explanation:
The given equation is in the form y = mx+b
m = -3/2 is the slope
b = 2 is the y intercept
The y intercept tells us where the graph crosses the vertical y axis. In this case, it's at 2 on the y axis. Think of the y axis as a number line that is simply vertical.
So we'll have (0,2) as one point on the line.
From this point, move down 3 units and to the right 2 units to arrive at (2,-1) as our next point. We only need two points to graph a straight line. You can repeat the process "down 3, over to the right 2" to generate as many points as you want.
The "down 3, over to the right 2" is from the slope -3/2
slope = rise/run = -3/2
rise = -3 means we move down 3
run = 2 means we move to the right 2
---------------------
Another approach is to plug in numbers for x to get corresponding values for y.
If we pick on x = 0, then,
y = (-3/2)*x + 2
y = (-3/2)*0 + 2
y = -1.5*0 + 2
y = 0 + 2
y = 2
So this shows (0,2) is one point on the line.
If we plug in x = 2, then,
y = (-3/2)*x + 2
y = (-3/2)*2 + 2
y = -1.5*2 + 2
y = -3+2
y = -1
Meaning (2,-1) is another point on the line.

Answer:
B
Step-by-step explanation:
A "box and whisker" plot is a visual representation of the 5-number summary of a data set. It shows you the minimum, maximum, median, and the 1st and 3rd quartile values.
__
The given data is sorted, so the first value (5) and the last value (19) will be the ends of the whiskers. (Eliminates choice A)
There are 15 data values, so the 8th one is the middle one, the median. That value is 10, and corresponds to the vertical line in the box. (Eliminates choices C and D.)
When the median is removed from the data set, it is divided into two parts, each containing 7 data values. The middle (4th) one of each of these are the 1st and 3rd quartiles, the ends of the box. They are 8 and 17, confirming that choice B is the correct box and whisker plot.
Annabelle and Ezra have a dog that eats 3/4 of a cup of food every morning. Annabelle lost the 1/4 cup so she used the 1/3 cup and gave him 2/3 of a cup of food. Ezra says that Annabelle did not feed the dog enough food. Annabelle says she gave him more than enough.
Who is right? Explain how they can compare the fractions to figure out who is correct.
Answer:
Ezra is correct. 2/3 = 8/12, 3/4 = 9/12. 8/12 is less than 9/12
Step-by-step explanation:
We can multiply the fractions (by multiplying both the top and bottom of a fraction, its value remains the same) by the opposite denominator. This gives us a least common denominator, so we can easily compaire the fractions.
Ezra is correct beacuse it gives us a least common denominator, so we can easily compare the fractions.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given that Annabelle and Ezra have a dog that eats 3/4 of a cup of food every morning.
Also that Annabelle lost the 1/4 cup so she used the 1/3 cup and gave him 2/3 of a cup of food.
Thus We have to multiply the fractions (by multiplying both the top and bottom of a fraction, means the value remains the same) by the opposite denominator.
2/3 = 8/12,
3/4 = 9/12.
8/12 is less than 9/12
Hence, Ezra is correct beacuse it gives us a least common denominator, so we can easily compare the fractions.

Answer:
x=35
Step-by-step explanation:
The sum of the angles of the triangle is 180
x+10 + x + 3x-5 = 180
Combine like terms
5x +5 = 180
Subtract 5 from each side
5x+5-5= 180-5
5x = 175
Divide each side by 5
5x/5 =175/5
x=35
Answer:
35 is correct answer

Could you find the Area?
Answer: 35!
Step-by-step explanation
The length is 7 and the width is 10 so length x width = area which is 7x10=70. The area of the small rectangle is 5x7 which is 35. So altogether 70+35=105. and you would have to subtract it because you only want to know the length of the frame. So 70-35=35!

4 \$70.8099 \$159.30
28 \$495.60
How long does it take him to make \$132.75
Answer:
7.5 hrs.
Step-by-step explanation:
First we need to find how much Magan earns per hour using the slope-intercept form: y = mx + b
Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will be using: (4, 70.80) and (9, 159.30) to find the slope of this table..
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{159.30-70.80}{9-4} \\\\m=\frac{88.50}{5} \\\\m=17.7[/tex]
y = mx + b
y = 17.7x + b
I will be using (4, 70.80) to find the value of b
(4, 70.80)
y = 17.7x + b
70.80 = 17.7(4) + b
70.80 = 70.80 + b
-70.80 -70.80
0 = b
y = 17.7x + b ==> y = 17.7x + 0 = OR y = 17.7x (since the value of b is 0)
The question wants us to find out how long it took Magan to make $132.75
y = 17.7x
132.75 = 17.7x
/17.7 /17.7
7.5 = x
This means that it took him 7.5 (seven and a half) hours to make $132.72
