Answer:
Comparing the L.H.S with the R.H.S
a = 1b = 5c = 9Step-by-step explanation:
Given
3 1/2 divided by 2 1/4 = a b/ c
solving the left-hand side of the equation
[tex]3\frac{1}{2}\div \:2\frac{1}{4}[/tex]
Convert mixed numbers to improper fractions
[tex]3\frac{1}{2}=\frac{7}{2}[/tex][tex]2\frac{1}{4}=\frac{9}{4}[/tex]so the expression becomes
[tex]3\frac{1}{2}\:\div 2\frac{1}{4}=\frac{7}{2}\div \:\frac{9}{4}[/tex]
Apply the fraction rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]
[tex]=\frac{7}{2}\times \frac{4}{9}[/tex]
Cross cancel the common factor
[tex]=\frac{7}{1}\times \frac{2}{9}[/tex]
Multiply fractions: [tex]\frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]=\frac{7\times \:2}{1\times \:9}[/tex]
[tex]=\frac{14}{9}[/tex]
Convert improper fractions to mixed numbers
[tex]=1\frac{5}{9}[/tex]
Thus, the main expression becomes
[tex]\:1\frac{5}{9}=a\frac{b}{c}[/tex]
Thus, comparing the L.H.S with the R.H.S
a = 1b = 5c = 9Please help I’ve been stuck for an hour!!!

If Y varies directly with X,
find Y when X=24, if Y = 5
when X= 30.
Answer:
Y=4 when X =24
Step-by-step explanation:
If Y varies directly with X, find Y when X=24, if Y = 5 when X= 30.
We can write:
[tex]Y\:\alpha\: X\\Y=kX[/tex]
Where k is known as constant of proportionality
Now, we are given: Y = 5 when X= 30.
We can find value of k
[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]
Now, we will find Y when X = 24
and k=1/6
[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]
So, Y=4 when X =24.

-2n divided by 3 + (4n - n), when n = 6
Step-by-step explanation:
Divisor = -2n = -2 * 6 = - 12
Dividend = 3 + ( 4 * 6 - 6) = 3 + 18 = 21
Now
21 / -12
dividing numerator and denominator by 3
= - 7 / 4
Step-by-step explanation:
= -2n
= -2×6
= -12
again,
=3+(4n-n)
= 3+4×6-6
=3+24-6
=21
now,
= -12

16. 68, ......., 96, 113, 132
a. 80
b. 81
c. 96
Answer:
B.
Step-by-step explanation:
So there is a pattern:
132-113=19
113-96=17
96-? is going to equal 15
So 96-81=15
And 81-68=13
Using the equation ŷ = 2.6 − 3.1x, what is the predicted value if x is 4.3?
Select one:
a. −10.73
b. 10.73
c. 15.93
d. −15.93
e. 0.54
Work Shown:
Plug x = 4.3 into the equation given
ŷ = 2.6 − 3.1x
ŷ = 2.6 − 3.1(4.3)
ŷ = 2.6 − 13.33
ŷ = -10.73
Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.

Answer:
Step-by-step explanation:
From the given information:
We learned that it is possible that all entities can be in one of two states i.e. 0 or 1. Thus, all 5 entities can either be 0 or 1 (2 states).
∴
Number of outcomes = 2 × 2 × 2 × 2 × 2
= 2⁵
= 32

All the outcomes of W = {(1, 1, x₃, x₄, x₅) (x₁, x₂, 1, 1, x₅) (1, x₂, 1, x₄, 1)}
A label is twice as long as it is wide. If the length of the label is 10 cm, find the
area of the label.
O 20 square centimeters
O 50 square centimeters
O 60 square centimeters
O 70 square centimeters
Answer:
50 square centimeters
Step-by-step explanation:
Long means length, and we know the length of the label, 10 centimeters. That means the width is half of 10 centimeters, or 5 centimeters. Now, we multiply 10 and 5 to get 50. That means the area of the label is 50 square centimeters

Step-by-step explanation:
y = -2x - 9
6x - 5y = -19
Hey there!
y = -2x - 9
6x - 5y = -19
We're going to label the first equation as "1" and the second equation as "2." Now, in order to find the values of "x" & "y," we need to even out the equations by placing their "x" and "y" markers on the same side of the equal sign.
Let's start off by adding 2x to both sides of equation 1.
1) y + 2x = -2x - 9 + 2x
Simplify.
Equation 1 is now: 2x + y = -9
Now, we need to multiply equation 1 equations by "3" in order to create "6x" in both equations. This helps us find the value of "y" because it cancels out the "x" in both equations.
1) (2x + y = -9) × 3
Simplify.
1) 6x + 3y = -27
2) 6x - 5y = -19
Now that our equations are lined up, we can subtract equation 2 from equation 1.
6x - 6x = 03y - (-5y) = 3y + 5y = 8y-27 -(-19) = -27 + 19 = -8Let's put this all together now.
8y = -8
Divide both sides by 8!
8y ÷ 8 = -8 ÷ 8
Simplify.
y = -1Now that we have the value of y, we can easily plug it into one of our equations to get our "x" value.
Equation 1: y = -2x - 9
Plug in "-1" for "y."
-1 = -2x - 9
Add 9 to both sides
-1 + 9 = -2x - 9 + 9
Simplify.
8 = -2x
Divide both sides by -2.
8 ÷ -2 = -2x ÷ -2
Simplify.
-4 = xTherefore, x = -4 & y = -1
(-4, -1)Hope this helped! :)
Answer:
x = - 4
y = - 1
Step-by-step explanation:
y = -2x - 9
2x + y = - 92x + y = -9 (× 3)
6x - 5y = -19
______________
Elimination
6x + 3y = - 27
6x - 5y = - 19
____________ _
8y = - 8y = - 8/8y = -1Solution for x :
Substitution
6x - 5y = -19
6x - 5(-1) = -19
6x + 5 = - 19
6x = - 19 - 5
6x = - 24
x = -24/6
x = -46x - 5y = - 19
6(-4) - 5(-1) = - 19
-24 + 5 = - 19
-19 = - 19

The number of patients treated in a dental office each day was recorded for 11 days. Find the
median for this data
10, 20.15, 15, 10, 14, 15, 15, 13, 25, 24
If the answer is not a whole number, enter it as a decimal. Round the decimal to the nearest
tenth, if needed
Answer:
15
Step-by-step explanation:
10, 20.15, 15, 10, 14, 15, 15, 13, 25, 24
Organize the data from least to greatest
10, 10, 13, 14, 15, 15, 15, 20.15, 24, 25
Cross out data from each side until one point is left. So cross out one from one side, then another from the other side, continue this process until only one number is left. If two numbers are left, then take the average of the two numbers.
10, 10 , 13, 14, 15, 15, 20.15, 24, 25
