Hello There!

X = 6

First, we would add 5 to both sides so adding 5 to -5 is 0 and adding 5 to 7 is 12 so we would get the equation 2x = 12

Next, we would divide 2x by 2 and divide 12 by 2 and we would get a quotient of 6.

Our final answer is x = 6

Answer:

x=6

Step-by-step explanation:

2x - 5 = 7

Add 5 to each side

2x-5+5= 7+5

2x = 12

Divide by 2

2x/2 = 12/2

x = 6

Which type of triangle has one angle with a measurement greater than 90°?
masya89 [10]
Answer:
Obtuse-angled triangle

Explanation:
Triangles can be classified based on the measures of their angles as follows:
1- Right-angled triangle: Triangle that has one of its angles = 90°
2- Acute-angled triangle: Triangle that has all of its angles less than 90°
3- Obtuse-angled triangle: Triangle that has one of its angles greater than 90°

The attached image shows an obtuse-angled triangle. We can note that measure ∠B is greater than 90°

Hope this helps :)

When reading a book, Charlie made a list by writing down the page number of the last page he finished reading at the end of each
Assoli18 [71]

Answer:

No. of pages he read by the end of the 8th day = 425

Step-by-step explanation:

Charlie started from page 1 and read the same number of pages each day. Suppose x is the number of pages he read each day, the last page he read on the first day would be:

<u>Last page for day 1 = 1 + x</u>

This would be the first number he noted on the list.

The second page number can be determined by adding the number of pages he read to the last page for day 1.

Last page for day 2 = 1 + x + x

                                 = 1 + 2x

Similarly, the last page he read on the third day is:

Last page for day 3 = 1 + 3x. Similarly,

Last page for day 4 = 1 + 4x

Last page for day 5 = 1 + 5x

Last page for day 6 = 1 + 6x

Last page for day 7 = 1 + 7x

Last page for day 8 = 1 + 8x

His Mom added all of the page numbers and got a total of 432. So,

432 = 1+x + 1+2x + 1+3x + 1+4x + 1+5x + 1+6x + 1+7x + 1+8x

432 = 8 + 8x

8x = 432-8

8x = 424

x = 424/8

x = 53

By the end of the 8th day he actually read 1 + 8x pages. Substituting the value of x in this expression, we get:

No. of pages he read by the end of the 8th day = 1 + 8(53)

                                                                               = 1 + 424

No. of pages he read by the end of the 8th day = 425

Suppose you Just purchased a used truck. The number of miles on the odometer can be represented by the equation y = x + 40, 000,
igor_vitrenko [27]

Answer: f(x)= x+40000

Step-by-step explanation:

We write a function f(x) which gives the values of the function that are dependent on the independent variable "x".

Given: The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it.

Here y is dependent on x, so we replace y by f(x), then we get

f(x)= x+40000   which is the required answer.
