The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
Consider all positive integers that are multiples of 10 and are less than or equal to 200.
Let the number of the positive integer that are multiples of 10 be x. Then the equation will be
10x ≤ 200
Then the value of the x will be
x ≤ 20
The set of numbers is given below.
Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}
The set which is divisible by 15 will be
Set = 6 {30, 6,0 90, 120, 150, 180}
Then the fraction of those integers are multiples of 15 will be
⇒ 6 / 20
⇒ 3/10
The fraction of those integers are multiples of 15 will be 3/10. Then the correct option is C.

2. Complete the function
table using the rule
y = x + 4.5
Answer:
Step-by-step explanation:
Given function is,
y = x + 4.5
To complete the input-output table given in the picture we will substitute the values of x in the function rule,
For x = 1,
y = 1 + 4.5
y = 5.5
For x = 3
y = 3 + 4.5
y = 7.5
Therefore, complete table will be,

Meryl buys new baseball equipment for $2000. The purchase made is with a credit card that has a 19% APR. Meryl makes a $150 payment monthly. How many months will it take Meryl to pay off the balance?
Answer:
It will take Meryl 15.09 months to pay off the balance.
Step-by-step explanation:
This can be calculated using the formula for calculating the present value of an ordinary annuity as follows:
PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)
Where;
PV = Present value or the cost of the new baseball equipment = $2000
P = Monthly payment = $150
r = Monthly interest rate = annual percentage rate (APR) / 12 = 19% / 12 = 0.19 / 12 = 0.0158333333333333
n = number of months it will take Meryl to pay off the balance = ?
Substitute the values into equation (1) and solve for n, we have:
2000 = 150 * ((1 - (1 / (1 + 0.0158333333333333))^n) / 0.0158333333333333)
2000 / 150 = (1 - (1 / 1.0158333333333333)^n) / 0.0158333333333333
13.3333333333333 = (1 - 0.984413453650536^n) / 0.0158333333333333
13.3333333333333 * 0.0158333333333333 = 1 - 0.984413453650536^n
0.21111111111111 = 1 - 0.984413453650536^n
0.984413453650536^n = 1 - 0.21111111111111
0.984413453650536^n = 0.78888888888889
loglinearize both sides, we have:
nlog0.984413453650536 = log0.78888888888889
n = log0.78888888888889 / log0.984413453650536
n = -0.102984160720249 / -0.00682245957075587
n = 15.0948729929724
Rounding to 2 decimal places, we have:
n = 15.09
Therefore, it will take Meryl 15.09 months to pay off the balance.

A scientific calculator has 42 buttons. There are twice as many grey buttons as orange buttons. There are two more white buttons than grey buttons. There twice as many black buttons as white buttons. WRITE AN EQUATION TO CALCULATE HOW MANY BUTTONS OF EACH COLOUR THERE ARE. LET X REPRESENT THE NUMBER OF ORANGE BUTTONS.
Answer:
x + 2x + 2x + 2 + 4x + 4 = 42
Step-by-step explanation:
Let us assume the number of orange buttons be x
So, the grey buttons be 2x
The white buttons would be 2x + 2
And the black buttons be 2(2x + 2) i.e. 4x + 4
Also the total is 42 buttons
So, the equation is
x + 2x + 2x + 2 + 4x + 4 = 42

A group of friends were working on a student film. They spent all their budget on equipment and props. They spent $216 on equipment, and 73% of the total budget on props. What was the total budget for their student film?
Answer:
800
Step-by-step explanation:
100x216=27
21600 divided by 27=800
The total budget for this student film was 800$.
What is the percentage?A percent is a quantity or ratio that, in mathematics, represents a portion of one hundred. A dimensionless relationship between two numbers can be represented in a variety of ways, such as through ratios, fractions, and decimals. The symbol "%" is frequently written after the number to indicate percentages. Additionally, you can indicate them by adding "percent" or "pct" after the number.
Given, A bunch of buddies was producing a school movie. Their whole budget was spent on props and equipment. Equipment cost $216, while props accounted for 73% of the whole budget. Hence,
Percent of their budget they spent on equipment = 100 - 73 = 27
Also given the money spent on budget = 216
Thus, 27 % of the total budget = 216
1 % of the total budget = 8
Total budget = 8 *100
Therefore, This student movie had an 800-dollar budget in total.

Step-by-step explanation:

Answer:
x=216
n=18
m=5
x=-11
Step-by-step explanation:
12= x/18
Can also be written as 12=x÷18. Multiply each side by 18 to isolate x and to find the value of x.
This will cause the equation to look like 12×18=x÷18×18. This will eliminate 18 from the right side of the equation and for 12×18 to equal 216. After simplifying it will equal:
x=216
3=n/6
Can also be written as 3=n÷6. Multiply each side by 6 to isolate n in order to find the value of n.
This will cause the equation to look like 3×6=n÷6×6. After simplifying the equation by causing the 6 on the right side of the equation to cancel out and multipyling 3 and 6 together, it will equal:
n=18
-10=m+(-15)
Add 15 to each side of the equation to find the value of m.
This will cause the equation to look like -10+15=m+(-15)+15. This will cause the 15s on the right side of the equation to cancel out and for the left side of the equation to equal 5. After doing this, the equation will equal:
5=m
-7+x=-18
Add 7 to each side of the equation to isolate x in order to find the value of x.
This will cause the equation to look like -7+7+x=-18+7. This will cancel out the 7s on the left side of the equal and the right side of the equation will equal -11. After using these steps to simplify, the equation will equal:
x=-11

Is 2(6 – 3x) + x equivalent to 2(3x) + x + 12?
Answer:
Step-by-step explanation:
Carry out indicated operations to see if they are equal
2(6-3x)+x=2(3x)+x+12
2(6)+2(-3x)+x=6x+x+12
12-6x+x=6x+x+12 combine like terms on both sides
12-5x=12+7x (we can see here they are unequal but we can continue) subtract 12 from both sides
-5x=7x divide both sides by x
-5=7
7 is not equal to -5 so the original expressions aren’t equivalent.

Let's solve your system by substitution.
y=2x+1;y=4x−1
Step: Solve y=2x+1for y:
y=2x+1
Step: Substitute2x+1foryiny=4x−1:
y=4x−1
2x+1=4x−1
2x+1+−4x=4x−1+−4x(Add -4x to both sides)
