Step-by-step explanation:
QUESTION A:
Find the GCD (or HCF) of numerator and denominator
GCD of 15 and 30 is 15
Divide both the numerator and denominator by the GCD
15 ÷ 15
30 ÷ 15
Reduced fraction:
1/2
Therefore, 15/30 simplified to lowest terms is 1/2.
Thus, option d is your answer
QUESTION B:
Find the GCD (or HCF) of numerator and denominator
GCD of 12 and 3 is 3
Divide both the numerator and denominator by the GCD
12 ÷ 3
3 ÷ 3
Reduced fraction:
4/1
Therefore, 12/3 simplified to lowest terms is 4/1 or 1/4.
Thus option a is your answer

Which of the following statements is not true about the graph of a system of equations with infinitely many solutions? please answer correctly!
Answer:
The lines will have one positive y-intercept and one negative y-intercept is not true about the graph of a system of equations with infinitely many solutions.
Step-by-step explanation:
A system of equations with infinitely many solutions suggests on the graph, the equations will appear to be the same (they will look like one graph) because all points on each equation are equal. This suggests that it's impossible for the y-intercepts to be different, which is why the "lines will have one positive y-intercept and one negative y-intercept " is a false statement.
VERY EASY
Write the equations,
1. The sum of b and 15 is 27
2. 36 is the product of 4 and x
3. The difference of y and 9 is 12
4. k divided by 7 equals 21
Answer:
1. b+15=27
2. 4*X=36
3. y-9=12
4. k/7=21
Step-by-step explanation:
sum means addition and product means to multiply and difference means subtraction and divided means to divide :)

There are 4 yellow marbles and 9 blue marbles in a bag. You randomly choose one of the marbles. What is the probability of choosing a yellow marble? Write your answer as a fraction in simplest form.
The probability of choosing a yellow marble is ??
Answer:
4/13
Step-by-step explanation:
The total number of marbles is 4 + 9 = 13.
The probability of choosing a yellow marble is the number of yellow marbles divided by the total number of marbles. Since there are 4 yellow marbles, the probability of choosing a yellow marble is 4/13.

A function is shown g(x)=96.2(4)(x+2.5). The function g can be rewritten as the function h in the form h(x)=a(4)x. What is the value of a in the function h(x)?
I already know the answer, but I need the step-by-step. Thank you!
Answer:
96.2+240.5/x
Step-by-step explanation:
g(x)=96.2(4)(x+2.5)
h(x)=[96.2(x+2.5)](4)--------------Calculate[96.2(x+2.5)] first
h(x)=(96.2x+240.5)(4)
h(x)=x(96.2+240.5/x)(4)----------bring out X,So 96.2x+240.5 is divided by x
h(x)=(96.2+240.5/x)(4)x
h(x)=a(4)x
so a=96.2+240.5/x
The value of a is 96.2 + 240.5/x.
What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).
Given g(x) = 96.2(4)(x+2.5),
and h(x) = a(4)x,
to find a
h(x) = [96.2(x + 2.5)](4)--------------Calculate[96.2(x+2.5)] first
h(x) = (96.2x + 240.5)(4)
h(x) = x(96.2 + 240.5/x)(4)--------bring out x,So 96.2x+240.5 is divided by x
h(x) = (96.2 + 240.5/x)(4)x
h(x) = a(4)x
so a = 96.2 + 240.5/x
Hence value of a = 96.2 + 240.5/x
