8.88=-2.22(x-7)
what is x
Answer:
x=3Step-by-step explanation:
Let's solve your equation step-by-step.
8.88=−2.22(x−7)
Step 1: Simplify both sides of the equation.
8.88=−2.22(x−7)
8.88=(−2.22)(x)+(−2.22)(−7) (Distribute)
8.88=−2.22x+15.54
Step 2: Flip the equation.
−2.22x+15.54=8.88
Step 3: Subtract 15.54 from both sides.
−2.22x+15.54−15.54=8.88−15.54
−2.22x=−6.66
Step 4: Divide both sides by -2.22.
−2.22x /−2.22
=
−6.66 /−2.22
x=3

50 to 60 as a fraction in simplest form
Answer:
5/6
Step-by-step explanation:
50/60 in simplest form is 5/6
You would divide both sides by 10
The simplified expression of the expression 50 to 60 is 5/6
How to simplify the expressionFrom the question, we have the following parameters that can be used in our computation:
50 to 60
Express as equation
50 to 60 = 50/60
Divide 50 by 60
So, we have the following representation
50 to 60 = 5/6
Using the above as a guide, we have the following:
The expression cannot be further simplified
Hence, the simplified expression is 5/6

A train traveled 1/4 of the distance between two cities in 2/3 of an hour. at this rate, what fraction of the distance can the train travel in one hour
====================================================
Explanation:
A = fraction of the distance traveled in 2/3 of an hourB = time value that pairs up with AC = fraction of the distance traveled in 1 hourD = time value that pairs with CIn this case,
A = 1/4B = 2/3C = unknownD = 1We can set up the proportion
A/B = C/D
Which cross multiplies to
A*D = B*C
Let's plug in the known values and solve for C
A*D = B*C
(1/4)*(1) = (2/3)*C
1/4 = (2/3)*C
(2/3)*C = 1/4
3*(2/3)*C = 3*(1/4) ..... multiply both sides by 3
2C = 3/4
(1/2)*2C = (1/2)*(3/4) .... multiply both sides by 1/2
C = (1*3)/(2*4)
C = 3/8
The train travels 3/8 of the distance in 1 hour.

8. Each box in a set of decorative storage boxes is a cube.
a) The sides of the smallest box are 30% of the length of the sides of the largest
box. The volume of the largest box is 7784 cubic inches more than the
volume of the smallest box. Define one or more variables, and write an
equation that represents the situation.
b) What are the lengths of the sides of the largest and smallest boxes?
c) Two of the other boxes have a total volume of 2457 cubic inches. The length
of the sides of the smaller of these boxes is 75% of those of the larger box.
Write and solve an equation to find the lengths of the sides of the boxes.
Answer:
20 in and 6 in12 in and 9 inStep-by-step explanation:
a) Let the side of the larger box be x, then the side of the smaller box is 0.3x.
Their volumes are:
x³ and (0.3x)³ = 0.027x³The difference in volumes:
x³ - 0.027x³ = 77840.973x³ = 7784x³ = 7784/0.973x³ = 8000x = ∛8000x = 20b) The sides are 20 in and 20*0.3 = 6 in
c) The other two boxes with sides x and 0.75x
Sum of the volumes:
x³ + (0.75x)³ = 2457x³ + 0.421875x³ = 24571.421875x³ = 2457x³ = 2457/1.421875x³ = 1728 x = ∛1728x = 12Sides of the boxes are 12 in and 12*0.75 = 9 in

f (x) = (x-1) (x+3)..........................................less the periods
Which equation is represented by the line
Answer:
First, we need to find the slope of this line.
Slope is defined as rise over run, or change in y over change in x. We find two points on this line, and see that the slope is -4.
Then, we find the y-intercept, which in this case is 0.
Using slope intercept form, our answer is y=-4x
Let me know if this helps!
Answer:
y=-4x
Step-by-step explanation:
so the line goes down 4 evey 1 right so the slope is -4 and it goes through the y axis at 0 so the y intercoept is 0
the dataset below represents the heights of trees(in inches) 13, 82, 83, 95, 92, 98, 96. How many outliers are in this data set?
Answer:
3
Step-by-step explanation:
There are 3 outliers. 13, 82, 83. These outliers are marginally off by the rest of the set.
There is one outlier in the data. The value of outlier is 13.
What is an outlier?An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. It is a value that "lies outside" (is much smaller or larger than) most of the other values in a set of data. The outliers can be found from median and quartile range.
For the given situation,
The heights of trees(in inches) are 13, 82, 83, 95, 92, 98, 96.
Arrange them in ascending order,
⇒ [tex]13, 82, 83, 92, 95, 96, 98[/tex]
Here, median = 95
So, first quartile Q₁ = 82
third quartile, Q₃ = 96
Interquartile range, IQR = Q₃ - Q₁
⇒ [tex]96-82[/tex]
⇒ [tex]14[/tex]
Now, [tex]IQR(1.5)=14(1.5)[/tex]
⇒ [tex]21[/tex]
Then, high value = Q₃+1.5 IQR
⇒ [tex]96+21[/tex]
⇒ [tex]117[/tex]
Low value = Q₁-1.5 IQR
⇒ [tex]82-21[/tex]
⇒ [tex]61[/tex]
From the data, the value of outlier should lie less than 61 and greater than 117.
Hence we can conclude that there is one outlier in the data. The value of outlier is 13.

Option C is correct
Area of B patios a.74.42. B.37.21. C.144
Length of side of patio A = 12 yards
Area of patio A which is a square :
[tex] =\tt side \times side[/tex]
[tex] =\tt 12 \times 12[/tex]
[tex]\color{plum} = \tt144 \: {yards}^{2} [/tex]
Thus, Area of patio A = 144 yards²
Length of side of patio B = 6.1 yards
Area of patio B which is a square :
[tex] =\tt side \times side[/tex]
[tex] = \tt6.1 \times 6.1[/tex]
