Answer:

C) 5x - 2

Step-by-step explanation:

When parentheses are preceded by a + sign, they may be immediately removed. Two additions and one subtraction are called for here: 2x + 5 + 3x - 7. This is 5x - 2.

(2x + 5) + (3x - 7)

2x + 5 + 3x - 7

2x + 3x - 7 + 5

<u>5x - 2</u>.

The following circle graph represents first-quarter absences of Washington Middle School students. If 96 students had two or mor
UkoKoshka [18]
How many students had 3 or more absences?  Add together {45%, 21%, 23%} and subtract that sum from 100%:  11%.

How many students had two or more absences?  Add together this 11% and 21%:  32% had two or more absences.  Let the total number of students be n.  Then 32% of these n students add up to 96 students.  Thus, 0.32n = 96, and n= 300.

How many students had one absence?  The chart shows that that is 45%, and we know that there are 300 students total.  

Thus, the number of students who had one absence was 0.45(300) = 135.

In Triangle A B C, what is the value of x?
Nadusha1986 [10]

Answer:

x = 70

Step-by-step explanation:

180 - 112 = 68

2x + 2x + 12 + 68 = 360

4x + 80 = 360

4x = 360 - 80

4x = 280

x = 280/4

x = 70

2x = 2*70 = 140

2x + 12 = 2*70 + 12 = 152

180 - 140 = 40

112 + 40 = 152

180 - 152 = 28

112 + 28 = 140

The relationship between the number of hours a plumber works and the total work fee
Lynna [10]

Answer:

ANSWERS ARE B, C, AND D.

Step-by-step explanation:

I found the unit rate of 350 and 5, because we can use a calculator (as stated on top) I just punched in 350 divided by 5 and got 70. Now i know this may not sound that "professional", but nothing needs to always be professional as long as its efficient and most importantly gets you the right answer. I then took the time to multiply each number, (the ones on the left : 3, 3.5, 6, 7.25, and 8) by 70. If the answer you got on the calculator match up to the number on the right, (240, 420, 507.50, and 490) its correct, if it doesn't match up, you can tell that its most likely not the answer. You should end up with three answers that all end up having the unit rate of 70. Hope this helps anyone who needed it.

ANSWERS ARE B, C, AND D.
