Answer:
1)X+4=2x-17+10
X. =2x-7-4
11=X
DF=11+4
=15
2)FH~
11x+71=12x+32
12x-11x =71-32
X=39
FH=(11×39)+71+(12×39)+32
=1000
3)57+39+8x-12=180
8x+84-84=180-84
8x=96
X=12
4)11x+2=68
11x=66
X=6
5)114+X+37+X=139
2x+151. -151=139-151
X=-6
Answer:
1. x=11
2. x=39
3. x= 12
4. x=6
5. x=-6
Step-by-step explanation:
1. x+4= 10+2x-17
FG=GH
x+4=2x-7
11=x
2. 11x+71=12x+32
subtract from both sides
39=x
3. All angles of a triangle add to 180.
39+57+(8x-12)=180
96+(8x-12)=180
8x-12=84
8x=72
divide both sides by 8
x=9
4. Vertical angles are equal
68=11x+2
66=11x
divide
6=x
5. (114+x)+(37+x)=139
Add like terms
151+2x=139
subtract
2x=-12
x=-6

What is the solution for the equation, 2(4x – 6) = 8x – 12
Simplifying
2(4x + -6) = 8x + -12
Reorder the terms:
2(-6 + 4x) = 8x + -12
(-6 * 2 + 4x * 2) = 8x + -12
(-12 + 8x) = 8x + -12
Reorder the terms:
-12 + 8x = -12 + 8x
Add '12' to each side of the equation.
-12 + 12 + 8x = -12 + 12 + 8x
Combine like terms: -12 + 12 = 0
0 + 8x = -12 + 12 + 8x
8x = -12 + 12 + 8x
Combine like terms: -12 + 12 = 0
8x = 0 + 8x
8x = 8x
Add '-8x' to each side of the equation.
8x + -8x = 8x + -8x
Combine like terms: 8x + -8x = 0
0 = 8x + -8x
Combine like terms: 8x + -8x = 0
0 = 0
Solving
0 = 0
Answer:
X = 1
Step-by-step explanation:
2(4x - 6) = 8x - 12
(8x - 12) = 8x - 12
+ 12 + 12
8x = 8x
x = 1

Justin took a quiz with five multiple choice (A-D) and five true/false questions. How many different ways can he answer the questions?
Answer:
32,768 ways
Step-by-step explanation:
True/ false questions = 5 ; number of options = 2 (True or false)
Ways of answering = 2^5 = (2 * 2 * 2 * 2 * 2) = 32
Number of Multiple choice questions = 5
Number of options (A - D) = 4 options
Ways of answering = 4^5 = (4 * 4 * 4 * 4 * 4) = 1024
32 * 1024 = 32,768 ways

Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any number of plates, x?
Answer:
y = 8.80x
Step-by-step explanation:
Th price of one plate = $44 / 5 = $8.80
the cost of any x plate can be determined by multiplying $8.80 by x
y = $8.80x
For example if x is 10, y = $8.80(10) = $88
If x = 100, y = $8.80(100) = $880
Answer:
y = 8.80x
Step-by-step explanation:
Th price of one plate = $44 / 5 = $8.80
the cost of any x plate can be determined by multiplying $8.80 by x
y = $8.80x
For example if x is 10, y = $8.80(10) = $88
If x = 100, y = $8.80(100) = $880

An urn contains 5 red marbles 9 white and 7 blue marbles marbles.A child randomly selects three (without replacement) from the urn.Round to four decimal place.Find the probability all marbles are the same.
Answer:
0.0970
Step-by-step explanation:
Red marbles, R= 5
White, W = 9
Blue, B = 7
Total = (5 + 9 + 7) = 21
Selecting 3 marbles without replacement :
Probability that all marbles are the same
P(RRR) or P(BBB) or P(WWW)
(5/21 * 4/20 * 3/19) + (7/21 * 6/20 * 5/19) + (9/21 * 8/20 * 7/19)
0.0075187 + 0.0263157 + 0.0631578
= 0.0969922

U Pause o Help Jackson has a sprinkler that rotates in a circle with a 6 foot radius. What is the approximate area that Jackson can expect the sprinkler to cover?
Work out the area of this circle.
Take it to be 3.142 and write down all the digits given by your calculator.
21 cm
Answer:
If the 21 cm is circumference, the answer would be 35.09.
If the 21 cm is radius, the answer would be 1385.44.
If the 21 cm is diameter, the answer would be 346.36.
The velocity, v(t), of a particle, in inches per second, at time t seconds is v(t) = 4t3 + 3t2 + 2t + 1. What distance does the particle travel over the interval 0 ≤ t ≤ 1?
Answer:
The particle traveled 4 inches over the interval.
Step-by-step explanation:
What distance does the particle travel over the interval 0 ≤ t ≤ 1?
The distance is the integral of the velocity.
So
[tex]d(t) = \int_{0}^{1} v(t) dt[/tex]
[tex]d(t) = \int_{0}^{1} 4t^3 + 3t^2 + 2t + 1 dt[/tex]
We have that:
[tex]\int t^n dn = \frac{t^{n+1}}{n+1}[/tex]
So
[tex]d(t) = t^4 + t^3 + t^2 + t|_{0}^{1}[/tex]
Which is:
[tex]d(1) - d(0) = 1 + 1 + 1 + 1 = 4[/tex]
The particle traveled 4 inches over the interval.
