Answer:
A. x = -3
B. x = 2
C. x = 9/10
Step-by-step explanation:
(A) –12x + 9 = –15x
Collect like terms
9 = -15x + 12x
9 = -3x
x = 9 / -3
x = -3
(B) 4.5x + 11.5 = 8.5x + 3.5
4.5x - 8.5x = 3.5 - 11.5
-4x = -8
x = -8 / -4
x = 2
(C) 23x – 9 = 13x
-9 = 13x - 23x
-9 = -10x
x = -9 / -10
x = 9/10
Answer:
A) x= -3
B) x = -2
C) x = 27

Answer:
Step-by-step explanation:
you have a right triangle,
a^2+b^2=c^2
10^2=4^2+b^2
100=16+b^2
100-16=b^2
84=b^2
b=9.16
In the following equation, what is the y-intercept? y = -3.1 +7 03 o7
Answer:
the y-intercept, b, is 7
Step-by-step explanation:
Compare the given y = -3.1 +7 to y = mx + b. I must assume that you meant
y = -3.1x +7. It becomes evident that the slope, m, is -3.1 and the y-intercept, b, is 7.

Step-by-step explanation:
a. The expression that represents the difference is sales between the two sales will be:
9x - (7x + 3) = 9x - 7x - 3 = 2x - 3
b. What we do here is to simply substitute the value of 5 for x
mathematically, we have to substitute the value of 5 in the expression above
We have this as:

Stacia has 28 red and blue marbles. The ratio of red to blue marbles is 1:6. How many blue marbles does Stacia have?
Answer:
The total number of blue marbles = 24Step-by-step explanation:
Total number marbles Stacia has = 28
The ratio of red to blue marbles = 1 : 6
Let 'r' be the number of red marbles.Let 'b' be the number of blue linesAs the total number of marbles is 28. Thus,
r + b = 28
As the ratio of red to blue marbles is 1 to 6.
It means for each red marble 'r', we have 6 blue 'b' marbles. Thus,
b = 6r
now substituting b = 6r in the equation r + b = 28
r + b = 28
r + 6r = 28
7r = 28
divide both sides by 7
7r/7 = 28/7
r = 4
Thus,
The total number of red marbles ⇒ r = 4
The total number of blue marbles ⇒ b = 6r = 6(4) = 24
Therefore,
The total number of blue marbles = 24what is the scale factor?

A steel ball is dropped from a height and hits the ground 6.7 seconds after its release. From what height (in feet) was the ball released?
Step-by-step explanation:
Acceleration = g = 32.17ft/s²
Initial velocity = 0ft/s
Time taken = 6.7s
Using Kinematics,
we have s = ut + 0.5at².
=> s = (0)(6.7) + 0.5(32.17)(6.7)²
=> s = 722.06ft.

Deon is playing fetch with his dog with a toy that is shaped like a circle. The circumference of the toy is 12π inches.
Which measurement is closest to the area of the toy in square inches?
18.84 in.²
37.68 in.²
113.04 in.²
452.16 in.²
Answer:
113.04
Step-by-step explanation:
The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex]
Given that,
Deon is playing fetch with his dog with a toy that is shaped like a circle,
The circumference of the sculpture is 12π inches.
We have to determine,
Which measurement is closest to the area of the toy in square inches.
According to the question,
Circumference of the circle = [tex]2\pi r[/tex]
Where, circumference = [tex]12\pi[/tex]
Then,
[tex]12\pi =2\pi r \\\\r = \dfrac{12\pi }{2\pi }\\\\r = 6\ inches[/tex]
Therefore,
Deon is playing fetch with his dog with a toy that is shaped like a circle.
Area of the circle = [tex]\pi r^{2}[/tex]
Where, r = 6inches
Then,
Area of the circle is given by,
[tex]= \pi r ^{2}\\\\= 3.14 \times (6)^{2}\\\\= 3.14 \times 36\\\\= 113.04\ inches^{2}[/tex]
Hence, The required measurement is closest to the area of the toy is [tex]113.04\ inches^{2}[/tex].

Answer and Step-by-step explanation:
Hello!
You are told to round the number to the nearest whole number.
That means if the decimal is lower than 5 in the tenths place, the number would round down, and if the decimal is equal to or higher than 5 in the tenths place, the number would round up.
[tex]5\frac{5}{6}[/tex] is equal to 5.833. The number 8 is greater than 5, so the number rounds up to 6.
[tex]6\frac{1}{9}[/tex] is equal to 6.111. The number 1 is less than 5, so the number rounds down to 6.
Now we have the equation n - 6 = 6.
We solve for n.
Add 6 to both sides.
n = 12
n is equal to 12.
