Answer:
12 weekly payments
Step-by-step explanation:
Here, we want to get the number of weeks in which he made payment for the ring
We start by subtracting the deposit,
That would be;
225-75 = 150
Now, we proceed to divide what ie left by the weekly payment to get the number of weeks
That would be;
150/12.5 = 12

Answer:
y = 5x - 2
Step-by-step explanation:
The equation at the bottom is already in slope-intercept form, or y = mx + b format. It lacks one missing piece: b, or the y-intercept. However, the slope of the equation must be 5, because the number in place of the m equals the slope.
So, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex], and substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values. From there, we can isolate y to receive the full equation in slope-intercept form.
Since m represents the slope, substitute 5 in its place. Since the [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, choose any of the points provided and substitute its values into the formula. (Either one is fine, and I chose (1,3).) From there, isolate y to find the slope-intercept form and answer:
[tex]y-(3) = 5 (x-(1))\\y - 3 = 5(x-1)\\y - 3 = 5x -5\\y = 5x - 2[/tex]

1. x = 3
2. x = 6
3. not sure
Step-by-step explanation:
5x +2 (x+7) =14x -7
First expand the expandables
5x +2x +14 =14x-7
7x +14 =14x -7
14x -7x =14+7
7x=21 . Divide both sides by 7
x=3.
Step-by-step explanation:
1. 5x +2x + 2*7 =14x-7
7x + 14 = 14x - 7
14 +7 = 14x - 7x
21 = 7x
21/7 =x

Answer:
x = 4, BC = 17
Step-by-step explanation:
AC = AB + BC , substitute values
7x - 3 = 2x + 3x + 5
7x - 3 = 5x + 5 ( subtract 5x from both sides )
2x - 3 = 5 ( add 3 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Then
BC = 3x + 5 = 3(4) + 5 = 12 + 5 = 17
Carter bikes 1/4 mile in
5/6 minutes. At this rate, how many minutes does it take Carter to bike 1 mile?
Answer:
If Carter bikes 1/4 mile in 5/6 minutes, he bikes 1/4 mile in 50 seconds. (5/6 of a minute is equal to 50 seconds)
At this rate, if Carter bikes 1/4 mile in 50 seconds, he will be able to bike 2/4 of a mile in 100 seconds, 3/4 of a mile in 150 seconds, and a whole mile (4/4) in 200 seconds.
Converting 200 seconds to minutes, we have that it takes Carter 3 1/3 minutes to bike 1 mile.

Simplify the following expression 3°?
Answer: 1
Anything to the 0 power is 1
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
As you may already know, the number (the base) to the power (the exponent) is how many times you multiply the base. For instance:
3² = 3 * 3
3³ = 3 * 3 * 3
However, anything to the zeroth power is 1.
Why?
Well, for those above examples, take 3², you can also write it as:
3² = 1 * 3 * 3
It's just 1 times how many of that number. In 3 squared, there are twos 3's, not to be confused with 3 * 2.
In 3 to the zeroth power, there are zero 3's:
3° = 1
Now it has only the one.
This is just the way I was taught to think about it, but I'm sure there's a better explanation than mine.

A. Additional money earned for having an account
B. The limit for which an individual may use credit
C. The charge for the privilege of borrowing money
D. The total amount a borrower must repay a lender for a loan
Answer:
C
Step-by-step explanation:
Let's say you wanted to buy a television. The television cost $200 but you only have $100, so you ask your friend for some money. Your friend says they will give you money but you have to pay them back and pay them interest. So when you go pay them, you pay them $100 dollars along with the amount of money your friend wants you to pay them for borrowing their money. In the end you could end up giving them 120 instead of 100.
C. The charge for the privilege of borrowing money

Skylar is answering the following math problem: The value of an investment decreased by 10%. The original amount of the investment was $75.00. What is the current value of the investment? Skylar said 10% of $75.00 is $7.50, and since the investment decreased by that amount, you have to subtract $7.50 from $75.00 to arrive at the final answer of $67.50. Create one algebraic equation that can be used to arrive at the final answer of $67.50. Solve the equation to prove it results in an answer of $67.50. Be prepared to explain your thought process to the class.
Answer:
The given parameters of the investment are;
The rate of decrease of the investment, r = -10%
The original amount of the investment, P = $75.00
Let 'A' represent the final answer (value of the investment) after the decrease in the investment, 'r', is applied, we have;
The algebraic equation that can be used to arrive at the final answer, 'A', is given as follows;
A = P + r·P
Therefore by substituting the given values, we have;
A = $75.00 + (-10/100) × $75.00 = $75.00 - 0.1 × $75.00 = $75.00 - $7.50
A = $75.00 - $7.50 = $67.50
The final amount or answer, A = $67.50

Step-by-step explanation:
The parameters of the triangle having bisected angle are;
The length of the opposite and adjacent side of one of the halves of the bisected angle = 6 and 14 respectively
The length of the opposite and adjacent side of the other half of the bisected angle = (3·x - 12) and 21 respectively
By the angle bisector theorem, we have;
[tex]\dfrac{14}{6} = \dfrac{21}{3\cdot x - 12}[/tex]
Simplifying, we get;
[tex]\dfrac{14}{6} = \dfrac{2 \times 7}{2 \times 3} = \dfrac{7}{3}[/tex]
[tex]\dfrac{21}{3\cdot x - 12} = \dfrac{3 \times 7}{3 \times (x - 4)} = \dfrac{7}{x - 4}[/tex]
[tex]\dfrac{7}{3} = \dfrac{7}{ x - 4}[/tex]
7 × (x - 4) = 3 × 7
∴ x - 4 = 3
x = 3 + 4 = 7

Answer: Option B
Step-by-step explanation:
Which expression is equivalent to x² - 4x - 45?
А
(x - 9)(x - 5)
B
(x + 9)(x+5)
(20 +9)(x - 5)
D
(x - 9)(x+5)
Answer:
D. (x - 9)(x+5)
Step-by-step explanation:
[tex]x^{2} - 4x - 45[/tex] is your expression, so you have to factor it out. Since from the options available it's clear that the factors of -45 you use are some form of 9 and 5, we can use the process of elimination to figure out which are the correct ones.
First, through FOIL u know that in any factored form the last two terms in each bracket multiply together to make the last term in the expanded form.
So first, look at A. the last two terms are -9 and -5, which = 45 when multiplied together. 45 does not = -45, so it can't be A.
B has 9 and 5. When they're multiplied, they = 45, which does not = -45, so its not B
It can't be C either, because the first term of the first bracket in C is 20, and when multiplied with x it doesn't produce x^2.
Therefore it has to be D. u can check this by multiplying -9 and 5, which = -45, the final term in the expanded form. Also, -9 + 5 = -4, which is the middle term of the expanded form.
The equivalent expression to x² - 4x - 45 is (x - 9)(x + 5), which corresponds to option A.
To factor the quadratic expression x² - 4x - 45, we need to find two binomials that, when multiplied, give us the original expression.
We look for two numbers whose product is -45 (the coefficient of the constant term) and whose sum is -4 (the coefficient of the linear term, -4x). After some exploration, we find that the numbers -9 and 5 satisfy these conditions.
Thus, we can express x² - 4x - 45 as (x - 9)(x + 5). This is because when we multiply the two binomials (x - 9) and (x + 5) using the distributive property, we obtain the original quadratic expression.
This factored form, (x - 9)(x + 5), represents the equivalent expression to x² - 4x - 45.

Denise makes three times as many chocolate cupcakes as vanilla cupcakes. She also makes three dozen strawberry cupcakes. If Denise makes 132 cupcakes, how many dozen chocolate cupcakes does she make?
Answer:
6 dozens
Step-by-step explanation:
Vanilla, v = x
Chocolate, c = 3x
Strawberry, s = 3 dozens = 36
Total cupcakes = 132
Hence,
x + 3x + 36 = 132
4x = 96
x = 96 / 4
x = 24
Chocolate = 3 * 24 = 72
Dozens of chocolate = 72 /12 = 6 dozens

both days is 6.5 miles. If she ran at a pace of 6 miles per hour today,
how long did Kara run today?
9514 1404 393
Answer:
15 minutes
Step-by-step explanation:
We can let t represent the time in hours that Kara ran today. Then her distance today is ...
distance = speed · time
distance = 6t
Her total distance for both days is ...
5 + 6t = 6.5
6t = 1.5 . . . . . . . . . . subtract 5
t = 1.5/6 = 1/4 . . . . . divide by 6

the slope of the red line?
A: -5

C: -1/5
D: 1/5
Answer:

Step-by-step explanation:
For two lines to be parallel, they must have the same slope
since the slope of the green line is 5, the the red line will have the same slope as the green line,
The slope of the red line will therefore be 5
