Answer: 27.5 pages per hour

Step-by-step explanation:

Well, first you make the 12 minutes into an hour (times by 5), then times the pages she read (5.5) by 5, which is 27.5, so she reads 27.5 pages per hour, you can also use 27 and a half pages per hour.

Leokris [45]

Let 'c' represent the number of pictures Chelsea took.

Let 's' represent the number of pictures Sonya took.

For last year's Thanksgiving, c + s = 236

For this year's Thanksgiving, let 'x' represent the number of photos taken in total. x = c + s, where c and s are two integers that are the same (c = s).

And we know that for both years, c + s + x = 500.

As we know that c + s is already 236 from last year, we can remove c + s from the equation in bold and replace it with 236 instead.

236 + x = 500.

Now we have to isolate the x term.

x = 500 - 236

x = 264.

We know that x = c + s, where c and s are the same, so we can just use one of the variables and double it (so you either get 2c or 2s - it doesn't matter which one you pick because they're both the same).

2c = 264

c = 132

c = s

s = 132.

Both took 132 pictures this year.

GalinKa [24]

x= morning

y = afternoon

 x + y = 10

x=10-y

5x + 6y =57

5(10-y) +6y =57

50-5y +6y =57

y=7

x=10-7 =3

 check 3*5 = 15, 7*6 = 42, 42 + 15 = 57

What is the value of x
Svet_ta [14]

Answer:

32

Step-by-step explanation:

Remark

Every triangle has 180 degrees as the total of its 3 angles.

Equation

x + 98 + 50 = 180

Solution

Combine the like terms on the left

x + 148 = 180

Subtract 148 fro both sides of the equation

x + 148- 148= 180 - 148

Combine

x = 32

x is 32 degrees in size

What is the value of n?
sineoko [7]
A. 69 degrees

exterior angles should equal 360 degrees so just add 131+160= 291 , 360-291= 69 degrees

or u can find it by finding the interior angle degrees by using supplementary angles. 180-131= 49 , 180-160= 20, 20+49=69, 180-69= 111 so the missing exterior angle corresponding interior is 111 and u can use supplementary angles to find the exterior. 180-111= 69 degrees
