Answer:
the correct answer is 3
Step-by-step explanation:
4x+24-2=7(4x+2)
4x+22=7*4x+2*7
4x+22=28x+14
4x-28x=14-22
-24x=-8
24x=8
x=3
There are 8 books lettered A-H on
the shelf. If Scott randomly chose
two books, what is the probability
that he chose books A and B?
Therefore, the probability that Scott chose books A and B is 1/28.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 means that the event will not occur and 1 means that the event is certain to occur. The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in many areas of mathematics, science, economics, and everyday life to help make predictions, decisions, and inferences.
Here,
The total number of ways Scott can choose 2 books out of 8 books is given by the combination formula:
C(8,2) = 8! / (2! * 6!) = 28
This means there are 28 possible pairs of books he could choose.
The probability that he chose books A and B is 1 out of 28 because there is only 1 way to choose books A and B out of the 28 possible pairs:
P(A and B) = 1/28

Answer:
B. 10
Step-by-step explanation:
This pair of triangles follows a scale factor. A scale factor is the factor that can get you an exact copy of a triangle, but with bigger or smaller side lengths. In this case, the scale factor is 2 (doing 12/6 on the left side is 2), and dividing that by 20 to get 10. Because we want the smaller triangle, we divide, not multiply. (you could also multiply by 1/2)

Could you please help me with number 6 thank you sm !!
Answer:
A) a = 4, b = 3Step-by-step explanation:
#6Given equation:
4/(x - 3) + 2/(x - 2) = 2Multiply all terms by (x - 3)(x - 2):
4(x - 2) + 2(x - 3) = 2(x - 3)(x - 2)2(x - 2) + (x - 3) = (x - 3)(x - 2)2x - 4 + x - 3 = x² - 5x + 6x² - 5x - 3x + 6 + 7 = 0x² - 8x + 13 = 0x = (8 ± √(8² - 4*13))/2 = (8 ± √12)/2 = (8 ± 2√3)/2 = 4 ± √3Compare this to the given form to get:
a = 4, b = 3Correct choice is A
On solving
x=4±√3
So
a=4 and b=3

Which is the graph of y=3/4x-3?
Answer:
Graph A
Step-by-step explanation:
The y-intercept is -3, which is the y-value when the graph hits the y-axis.
Graph A and B both hit the y-intercept of -3.
The slope is 3/4, which means the line rises 3 units as it runs 4.
This time, only Graph A has the correct slope.
The correct answer is [tex]\boxed{\text{Graph A}}[/tex]
-Chetan K
Answer:
Graph A
Step-by-step explanation:
The formula is in the form y=mx+c, where m is the gradient and m is the y-intercept, this means that the y-intercept is (0,-3) which rules out Graph B.
To find the gradient we use [tex]\frac{rise}{run}[/tex], this means that the vertical value has to be 3 and the horizontal distance 4 and this rules out Graph C as its gradient is 3/2. That means that graph A matches the equation the best.

Eleven more than 5 times a number is 31. What is the number?
Answer:
The number is 4.
Step-by-step explanation:
Let the number be x,
11 + 5x = 31
or, 5x = 31 - 11
or, 5x = 20
or, x = 20/5
so, x = 4
mZQPS = 88
mZRPS = 5x + 34°
mZQPR = 8x + 15 °
Find mZRPS:
Answer:
49
Step-by-step explanation:
First, you need to solve for x.
88 = 5x + 34 + 8x 15
88 = 13x + 49
88 - 49 = 13x
39 = 13x
39/13 = x
3 = x
Now substitute 3 in place of x to find rps
rps = 5x+34
rps = 5*3 + 34
rps = 15 + 34
rps = 49

Draw a model to help solve 5/6 + 1/4. Write your anserw as a mixed number
Answer:
Step-by-step explanation:
find the unknown sizes of an angles of the following polygons.
Answer:
A is an irregular pentagon - total angle is 540. So x is 100
(540 - 440=100)
B. 3a + 345 = 540
- 345 both sides
3a=195
÷3
a = 65
2a = 130 (65x2)
C. X = 120 (angles on straight lines adds to 180)
3y + 300 = 540
- 300
3y = 240
÷3
Y= 80
x 2
2Y = 160
