Answer:
x = -7
Step-by-step explanation:
[tex]-3x+7=8[/tex] subtract 7 on both sides
[tex]-3x=21[/tex] divide -3 into both sides
[tex]x=-7[/tex]
To check
-3(-7) = 21 + 7=28

Answer:
2700[tex]ft^{3}[/tex]
Step-by-step explanation:
First you find the volume of the bigger cuboid:
Volume= Length * width * height
Volume= 22 * 10 * 11
Volume= 2420[tex]ft^{3}[/tex]
Then the volume of the smaller cuboid:
Volume= Length * width * height
Volume= 7 * 10 * 4
Volume= 280[tex]ft^{3}[/tex]
Then add the volumes of the two shapes:
2420 + 280= 2700[tex]ft^{3}[/tex]

3m - 12 =18
Step by step
Answer:
3m=18+12
3m=30
divide both sides by 3
m=10
Answer:
m = 10
Step-by-step explanation:
3m - 12 =18
Add 12 to each side
3m - 12+12 =18+12
3m = 30
Divide by 3
3m/3 = 30/3
m = 10

show that (x+1)(x+3)(x+5) can be written in the form ax^3 + bx^2 + cx+ d where a,b,c and d are all positive integers.
Answer:
x³ + 9x² + 23x + 15
Step-by-step explanation:
Given
(x + 1)(x + 3)(x + 5) ← expand the first pair of factors using FOIL
= (x² + 4x + 3)(x + 5)
Each of the terms in the second factor is multiplied by each of the terms in the first factor, that is
x²(x + 5) + 4x(x + 5) + 3(x + 5) ← distribute the 3 parenthesis
= x³ + 5x² + 4x² + 20x + 3x + 15 ← collect like terms
= x³ + 9x² + 23x + 15 ← in the form ax³ + bx² + cx + d

52 regular playing cards are randomly dealt to four players with each players receiving 13 cards. What is the probability that each player will have exactly one ace
Answer:
The probability is 1/28,561
Step-by-step explanation:
Here, we want to find the probability that each of the players will receive exactly one ace.
In a deck of cards, we have 4 suites of 13 cards each, with each of the suites consisting of 1 ace.
So, the probability of getting an ace for each of the four players will be 4/52 = 1/13
Now, the probability of each of the players getting exactly one ace will be; first got one ace , second got one , third got one and fourth got one.
mathematically, this probability will be 1/13 * 1/13 * 1/13 * 1/13 = (1/13)^4 = 1/28,561

Step-by-step explanation:
Twice the sum of a number and 3 is equal to three times the difference of the number and 7. Find the number
Answer:
The number is 27
Step-by-step explanation:
Let us change the word statement to an algebraic equation
→ Assume that the number is x
→ Twice the sum of a number and 3, means add x by 3, then multiply the sum by 2
→ The algebraic expression is 2(x + 3)
→ Three times the difference of the number and 7, means subtract x and 7, then multiply the difference by 3
→ The algebraic expression is 3(x - 7)
→ Equate the two expressions
∴ 2(x + 3) = 3(x - 7)
→ Simplify each side
∵ 2(x + 3) = 2(x) + 2(3) = 2x + 6
∵ 3(x - 7) = 3(x) - 3(7) = 3x - 21
∴ 2x + 6 = 3x - 21
Let us solve the equation to find x
→ Subtract 6 from both sides
∴ 2x + 6 - 6 = 3x -21 - 6
∴ 2x = 3x - 21
→ Subtract 3x from both sides
∴ 2x - 3x = 3x - 3x - 27
∴ -x = -27
→ Divide both sides by -1
∴ x = 27
The number is 27

What is the mean of 25, 27, 32, 29, 42?
Step-by-step explanation:
To find the mean, or average, you add all of the numbers and divide the sum by how many there are.
In this case, you add 25,27,32,29, and 42 and then divide the sum by 5.
25+27=52+32=84+29=113+42=155.
Then divide.
155/5=31.

A file that is 242 megabytes is being downloaded. If the download is 17.1% complete, how many megabytes have been downloaded? Round your answer to the nearest tenth.
Answer:
4.1 megabytes
Step-by-step explanation:
well we use the rule of three
242 megabytes ------- 100%
x megabytes -------- 17.1%
(x megabytes)(100%)=(242 megabytes)(17.1%)
[tex]x=\frac{242*17.1}{100} \\\\x=\frac{4138.2}{100} \\\\x=4.1382\\\\x=4.1[/tex]
so there have been downloaded 4.1 megabytes

Answer:
108.8 yd²
Step-by-step explanation:
The area (A) of the triangle can be calculated as
A = [tex]\frac{1}{2}[/tex] absinC
where a, b are 2 sides and C the angle between them
Here a = 23, b = 9.5 and C = 85° , thus
A = 0.5 × 23 × 9.5 × sin85° ≈ 108.8 yd² ( to the nearest tenth )
Find the value of x that makes m
m
n
(2x + 20)
(32°
Answer: x= 20
Step-by-step explanation:
If m and n are parallel then the 3x and 2x+20 has to have the same measures which means they have to equal each other . So set them equal each other and solve for x.
2x + 20 = 3x
-2x -2x
20 = 1x
x= 20

What is the y-intercept of the function shown in the graph? Express your answer as an ordered pair.
Answer:
(0,4)
Step-by-step explanation:
2.)Solve for Y
3.)Solve for G
5.)Solve for B
6.)Solve for D
Answer:
See below
Step-by-step explanation:
2) x =5y Solve for y
Divide both sides by y
x/5 = y
3) f/g = h Solve for G
Multiply both sides by g
(g/1) f/g =h(g)
f =hg
Divide by h
f/h = g
5) bf = m Solve for b
divide both sides by f
bf/f = m/f
b = m/f
6) 8 = b/d solve for d
Multiply both sides by d
8 ( d) = b
Divide by 8
d = b/8
