Answer:
x = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Given
8 - (5 - 9x) = 7(1 - x) ← distribute parenthesis on both sides
8 - 5 + 9x = 7 - 7x
3 + 9x = 7 - 7x ( add 7x to both sides )
3 + 16x = 7 ( subtract 3 from both sides )
16x = 4 ( divide both sides by 16 )
x = [tex]\frac{4}{16}[/tex] = [tex]\frac{1}{4}[/tex]
Answer:
8 - (5 - 9x) = 7(1 - x)
8 - 5 + 9x = 7 - 7x
3 + 9x = 7 - 7x
3 + 16x = 7
16x = 4
x = 4/16

Answer:
Is this
Step-by-step explanation:
Answer:
D. 20
Step-by-step explanation:
if x = 20 then 3 x 20 + 10 = 70
and x = 20 so 70 + 20 = 90
and since this is a right angle, it all matches up :)

(1) Find the surface area of a Cuboid of length,breadth,and height equal to 12cm,8cm,and 5 cm respectively
Find the surface area of a Cuboid of length, breadth, and height equal to 12 cm, 8 cm and 5 cm respectively.
Answer:-Given:-[tex] \bullet [/tex] Length (l) of a Cuboid is 12 cm.
[tex] \bullet [/tex] Breadth (b) of a Cuboid is 8 cm.
[tex] \bullet [/tex] Height (h) of a Cuboid is 5 cm.
To Find:-The surface area of a Cuboid.
Solution:-We know,
Formula of surface area of a Cuboid is 2(lb + bh + lh) sq units.
So, Surface area of a Cuboid = 2(12×8 + 8×5 + 12×5) sq cm.
= 2(96 + 40 + 60) sq cm.
= 2 × 196
= 392 sq cm
The surface area of a Cuboid is 392 sq cm. [Answer]A scale model of a statue is 32 centimeters tall. Using a scale factor of 1:12, find the height of the actual statue in centimeters,

Answer:
D = -3, -2, -1, 1, 4
R = -2, -1, -1, 0, 2
It is a FUNCTION
Step-by-step explanation:
Let's assume 1 grid = 1 unit.
The points on the graph has the following coordinates.
(-3, 2), (-2, -2), (-1, -1), (1, -1), (4, 0)
D = the set of input values/x-values
D = -3, -2, -1, 1, 4
R = the set of output values/y-values
R = -2, -1, -1, 0, 2
✅It is A FUNCTION because each x-value has exactly 1 y-value attached to it.
Amy wants to frame a poster that has a width of 8 inches and a length of 1 foot.What is the perimeter of the poster?
Answer:
Perimeter of the poster is 18 foot.
Step-by-step explanation:
Lengths of the poster = 1 inches
Width of the poster = 8 inches
Poster is in the form of a rectangle.
And the expression that defines the perimeter of the poster is,
Perimeter = 2(Length + Width)
By substituting the values of length and width in the expression,
Perimeter = 2(1 + 8)
= 2(9)
= 18 foot
Therefore, perimeter of the poster is 18 foot.

Find the scale factor of the dilation. Then tell whether the dilation is a reduction or an enlargement
Answer:
The answer is "[tex]\frac{3}{7}[/tex]"
Step-by-step explanation:
Please find the complete question:
The dilation scale factor will be the same:
[tex]=\frac{\text{Picture to Center Gap}}{\text{Related pre-image distance to the middle}}[/tex]
Throughout the picture, the distance is [tex]CP'=6[/tex], while the equivalent distance is [tex]CP=14[/tex]. The factor of scale is then[tex]=\frac{CP'}{CP} =\frac{6}{14} =\frac{3}{7}[/tex]
The decrease because if a factor of scale is below 1 and a factor of scale is higher than 1. Dilation is a reduction since [tex]\frac{3}{7}<1[/tex], therefore the scale factor is [tex]\frac{3}{7}[/tex].
The scale factor of the given dilation is; 6/14 and the dilation is a reduction
Transformations
The image of the object undergoing transformation is missing and so i have attached it.
From the attached object, we se that CP = 14.
Also CP' = 6
Thus; Scale factor is 6/14
Now, reduction is reducing the dimensions while enlargement is increasing the dimensions by a scale factor.
Since the denominator of the scale factor is greater than the numerator, then there is a reduction.

The cost of material used in making a Frisbee varies directly with the square of its diameter. If it costs the manufacturer $0.45 for the material of a Frisbee with a 9-inch diameter, then what is the cost for the material for a Frisbee with a 12-inch diameter?
Answer:
c = $0.8
Step-by-step explanation:
Let
cost of material = c
Diameter = d
c = k*d²
If it costs the manufacturer $0.45 for the material of a Frisbee with a 9-inch diameter
c = k*d²
0.45 = k * 9²
0.45 = k * 81
0.45 = 81k
k = 0.45/81
k = 0.0055555555555
what is the cost for the material for a Frisbee with a 12-inch diameter
c = k*d²
c = 0.0055555555555 * 12²
c = 0.0055555555555 * 144
c = $0.8

A company rents cars.
• The company charges a fee of $15 per day plus $0.20 per mile.
• The company also charges $10 per day for insurance.
• Jerry rented a car for x days.
Jerry drove the car 644 miles.
Write an equation that could be used to determine the total charge, y, for Jerry to rent the car.
Answer:y=128.8 +25x
Step-by-step explanation:
Insurance plus the fee means that he has to pay $25 per day(x). 644•$0.2 is 128.8, so that represents how much driving 644 miles costs him.

What is the x-value of the solution to this system of equations?
y=3x+11
x+2y=-6
Answer:
x = -4
Step-by-step explanation:
y=3x+11
x+2y= -6
2y = -x - 6
y= 3x + 11 (Multiply by -2)
2y = -x - 6
-2y = -6x - 22
0 = -7x - 28
28 = -7x
x = -4
