Solve the following equation:
12(b+2)+3b=−1
Enter your answer as a fraction.
Answer: -5/3
Step-by-step explanation:
12(b + 2) + 3b = -1
12b + 24 + 3b = -1
15b + 24 = -1
15b = -1-24
b = -25/15 = -5/3
The solution to the equation 12(b+2) + 3b = -1 is b = -5/3.
What is the solution to the given equation?Given the equation in the question:
12( b + 2 ) + 3b = -1
To solve the equation 12( b + 2 ) + 3b = -1, first apply the distributive property.
Distribute the 12 across the terms inside the parentheses:
12( b + 2 ) + 3b = -1
12×b + 12×2 + 3b = -1
Simplifying, we get:
12b + 24 + 3b = -1
Collect and combine the like terms on the left side of the equation:
12b + 3b + 24 = -1
15b + 24 = -1
Subtract 24 from both sides of the equation:
15b + 24 - 24 = -1 - 24
15b = -1 - 24
15b = -25
Divide both sides by 15:
b = -25/15
Simplify
b = -5/3
Therefore, the value of b is -5/3.

What is the volume in cubic centimeters if the
pyramid has a height of 27 centimeters?
Answer:
The volume of the pyramid would be 4500 cm³.Step-by-step explanation:
Formulas you would be using:
Volume of a pyramid: [tex]V = \frac{bh}{3}[/tex] b = base, h = height
Area of a trapezoid: [tex]A = \frac{a+b}{2} h[/tex] a = base₁ , b = base₂ , h = height
First, we're going to find the area of the trapezoid, which is the base of the pyramid.
We are given that a = 20, b = 30, h = 20
Plug it in:
[tex]\frac{20+30}{2} (20)[/tex] = 500 cm²
Now that we have found the base of the pyramid, we can plug it in along with the height of the pyramid.
[tex]V = \frac{(500)(27)}{3}[/tex] = 4500 cm³
Hope this helps :D
How do you find the area of a pizza with a diameter is 18 inches
Answer:
The area of the pizza with a diameter of 18 inches is 254.34 inches.
Step-by-step explanation:
The formula to find the area of a cirlce is A = pi x r^2 or pi times radius squared.
Second, we need to find our radius. To find the radius we need to divide the diameter by 2 to get the radius. In this case; 18 divided by 2 is 9.
Then, we need to plug the radius in the formula:
A = 3.14 x 9^2
9 squared or 9 times 9 equals 81
Next, multiply 81 by 3.14 and you get 254.34
Lastly, add the units of measurement, which would be inches.
Twice Brittany’s age is less than the age of Abraham Lincoln when he died. President Lincoln was 56 years old at the time of his death. Write an inequality to represent Brittany’s age, b. Brittany’s brother, Nate, is two years younger than Brittany. Write an equation for Nate’s age, n, in terms of Brittany’s age, b. Rewrite the expression from Part B to get the variable b alone on one side of the equation. (This is also called isolating b.) Substitute the value of b from Part C into the inequality you found in Part A. Solve the inequalities from parts A and D for the variables b and n, respectively. Could Brittany be 27 years old and Nate 26? Why or why not?
Answer:
2b < 56
n = b - 2
b = n + 2
n < 27
b < 28
No, because the difference between Brittany and Nate's age is 2years
Step-by-step explanation:
A.)
Twice Brittany’s age is less than the age of Abraham Lincoln when he died. President Lincoln was 56 years old at the time of his death
Let Brittany's age = b
Twice Brittany's age = 2 × b = 2b
Lincoln's age = 56
2b < 56
B.)
Nate's age = n
Nate is 2 years younger than brittany who is aged 'b'
n = b - 2
C.) b = n + 2
D.)
If 2b < 56 and b = n + 2
2(n + 2) < 56
2n + 2 < 56
2n < 56 - 2
2n < 54 ; n < 27
2b < 56
b < 56/2
b < 28
No, because the difference between Brittany and Nate's age is 2years

If f(x) = 7x and g(x) = 3x+1, find (fºg)(x).
Answer:
21x+7
The value of (fog)(x) is, 21x+7
Step-by-step explanation:
Given the functions:
f(x) = 7x
g(x) = 3x+1
We have to find (fog)(x)
(fog)(x) = f(g(x))
substitute the function g(x) we have;
(fog)(x) = f(3x+1)
Replace the value of x from 3x+1 in f(x) we have;
(fog)(x) =7(3x+1)
⇒(fog)(x) = 21x+7
Therefore, the value of (fog)(x) is, 21x+7

The image is of a circle with two secant segments which intersect outside the circle. Inside and outside length of first one are marked as x and 5 respectively. Inside and outside length of second one are marked as 10 and 4 respectively.
A. 9
B. 8
C. 6.2
D. 22.5
Answer:
C
Step-by-step explanation:
Two secants drawn to a circle from a common external point, then
The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
5(5 + x) = 4(4 + 10) = 4 × 14 = 56
25 + 5x = 56 ( subtract 25 from both sides )
5x = 31 ( divide both sides by 5 )
x = 6.2 → C

Answer:
[tex]312 inches^{2}[/tex]
Step-by-step explanation:
The formula to work out the area of a triangle is : [tex]\frac{base*height}{2}[/tex]
to find the volume of this shape you would first need to work out the area of the triangle. You can do this by first multiplying the base of 6 by the height of 8, this gives you 48. The next step in working out the area is to divide 48 by 2, this gives you 24. This is because by multiplying the base by the height you are working out the area of a square with the same dimensions, and so will need to be divided by 2 to work out the area of the triangle. Now that you have worked out the area you can now work out the volume. To do this you would simply multiply the area of 24 by the height of 13, this gives you 312.
Working out the area:
1) Multiply 6 by 8.
[tex]6*8=48[/tex]
2) Divide 48 by 2.
[tex]48/2=24[/tex]
Working out the volume:
1) Multiply 24 by 13.
[tex]24*13=312 inches^{2}[/tex]

R=257
a=4.88
b=37.4
t=61.5
Answer:
G ≈ 1.46
Step-by-step explanation:
Given
G = [tex]\frac{R+ab}{at}[/tex] , substitute values
G = [tex]\frac{257 4.88(37.4)}{4.88(61.5)}[/tex]
= [tex]\frac{257+182.512}{300.12}[/tex]
