Next Question
Answer:
Step-by-step explanation:
Given that:
Number of books, b α number of children enrolled
b α C
b = kC
Number of books, b = 3 for each child, c = 1 enrolled
Total number of books in class room :
Total number of books = Number of books per child * Number of child)
Total number of books = 3 * Numbe of child
The answer is c i believe

5/2k+1=-9
What does k equal?
Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
If you mean,
[tex] \frac{5}{2k} + 1 = - 9[/tex]
Then the answer would be,
[tex]k = - \frac{1}{4} [/tex]
But, if you mean
[tex] \frac{5}{2} k + 1 = - 9[/tex]
Then the answer would be,
[tex]k = - 4[/tex]

Answer:
c>72
Step-by-step explanation:
−12+c>60
Step 1: Simplify both sides of the inequality.
c−12>60
Step 2: Add 12 to both sides.
c−12+12>60+12
c>72
Find the length of the third side. If necessary, write in simplest radical form. 1 2
Answer:
√3
Step-by-step explanation:
Using the pythagorean theorem, we know that a^2 + b^2 = c^2
In this case, c = 2, which means that a^2 + b^2 = 4
Since we know that a = 1, this means that a^2 is also 1. So, we know that b^2 = 4 - 1
Therefore, b^2 = 3
So, the answer is square root 3

Jasmine had some candy to give to her three children. She first took four pieces for herself and then evenly divided the rest among her children. Each child received two pieces. With how many pieces did she start?
Answer:
10 pieces
Step-by-step explanation:
She gave herself 4 pieces, and each child 2 pieces. If she has 3 children, she gave them 6 pieces.
(3*2=6) and then you add with the amount she gave herself, (6+4) that would be 10. She started with 10 pieces.
An equation would be:
x= 4+(2*3)
I hope this helps!
(Also this equation seems a bit easy, am I reading it wrong? If I am be sure to correct me :) )

Line G has a slope of -2/3. Line age is perpendicular to G. What is the slope of line h?
Perpendicular lines has negative reciprocal slopes.
"Negative reciprocal" is just a fancy way of
saying flip the fraction and change the sign.
So flipping the fraction gives us -3/2 and change the sign to get +3/2.

Answer:
so C but might be A
Step-by-step explanation:
Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.
good luck, i hope this helps :)

a woman is 5 times as old as her daughter in 15 years time to be two times as old as her daughter to find a mother's presentsage
Answer:
25 years.
Step-by-step explanation:
Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:
5 x 5 = 25
25 + 15 = 40
40/2 = 20
5 + 15 = 20
Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.
Lines a and b are parallel. Parallel lines a and b are cut by transversals s and t. The angles formed by the intersection of lines a, s, and t, clockwise from top left are blank, blank, blank, blank, (7 x) degrees, blank; formed by lines b and s are blank, blank, blank, (11 x) degrees; formed by lines b and t are 90 degrees, blank, blank, blank. What is the value of x? 5 10 35 55
Answer:
x = 5
Step-by-step explanation:
Given that, exterior angles on the same side of a traversal are supplementary a Hence, sums up to 180°
Given the angles:
7x° + 11x° + 90° = 180°
18x° + 90° = 180°
18x° = 180° - 90°
18x° = 90°
x = 90° ÷ 18
x = 5
