A shelf is built on a wall, as shown below. What is the value of x?
(2x+1) + (3x-1)

Answers

Answer 1

Answer:

x = 18

Step-by-step explanation:

We need to find the value of x.

We know that the sum of angles of a triangle is equal to 180°. So, using this property,

2x+1+3x-1+90 = 180

2x+3x = 180-90

5x = 90

x = 18

So, the value of x is equal to 18.

Esther estimates that she will need about $8,600 for the first year of tuition at college. Her grandparents contribution will cover 65% of the tuition expenses, and Esther will need to save to pay for the rest. If Esther has 2 years to save, what is the minimum amount that she should save each month?

Answers

Answer:

$125.42

Step-by-step explanation:

Her grandparents will cover 65% of $8600, which is 8600 * 0.65 = $5590. Therefore, she needs to pay for the part they're not covering, which is $8600 - $5590 = $3010.

2 years = 24 months, so assuming she wants to save the same amount each month, we need to divide $3010 by 24 to get the amount per month. This gets us $125.42

The minimum amount that she should save each month for two years is $125.42.

What is the minimum amount she would have to save each month?

Percentage can be described as a fraction out of an amount that is usually expressed as a number out of hundred.

Amount given by her grandparents = 65% x 8600= $5590

Amount she would have to save each month for two years = (8600 - $5590) / 24 = $125.42

x    |   f(x)0    |    02    |    25    |    39    |    110  |    0

Step-by-step explanation:

On the left side of the chart, is the x values. The x values are listed on the x axis which is the horizontal line.

The right side of the chart are the y values. The y values are listed on the y axis which is the vertical line.

Knowing this, we can start

First, for all the answer that we know the x value, we need to find the number that matches on the x axis. Once we find that number, we go up or down on the y axis until we find the line.

If we know the y value, we need to find the number that matches on the y axis. Then we will go right until we find the line.

Remember - There CAN NOT be two y values for the same x value but THERE CAN BE two x values for the same y value

A woman bought some large frames for $13 each and some small frames for $6 each at a closeout sale. If she bought 18 frames for $136, find how many of each type
she bought
She bought large frames
vie

Answers

Answer:

she bought 4 large frames and 14 small frames!

Step-by-step explanation:

This is a system of equation problem!

let's say that x= large frames and y=small frames.

since there's 18 total, we already have our first equation set.

x+y=18

(number of large frames) + (number of small frames)= 18

13x would represent the large frames because each one is 13 dollars.

6y would represent the small frames because each one is 6 dollars.

Since she paid 136 dollars total, we can already tell that

13x+6y=136

(price of large frames*number of large frames) + (price of small frames*number of small frames)=136.

Now, time for the math!

Attached below is how you would work it out using substitution.

Hope this helps!

x=4 and y=14

Meaning that she bought 4 large frames and 14 small frames!

Madeline invested $51,000 in an account paying interest rate of 6 1/8% compounded daily. Harper invested 51000 in an account paying an interest rate of 5 3/4% compounded monthly. After 13 years, how much more money would Madeline have in her account than Harper

Answers

Answer:

$5564.87

Step-by-step explanation:

We are to determine the difference between the future values of each investment

The formula for calculating future value:

FV = P (1 + r)^mn

FV = Future value  

P = Present value  

R = interest rate  

N = number of years

m = number of compounding

Madeline

P = Present value = 51,000

R = interest rate = 0.06125 / 365 = 0.000168

N = number of years = 13

m = number of compounding = 365

51,000 x (1.000168)^4745  = 113,070.20

Harper

51,000 x (1.004792)^156 = 107,505.33

Difference = 113,070.20 - 107,505.33 = $5,564.87
