Answer:

inequality form: x $\leq$ -2 or x > 3

interval notation form: (-∞,-2] ∪ (3,∞)

Step-by-step explanation:

I attached a picture that shows all the work. You begin by isolating then solving for x on both sides. Then form a solution using the information found out about x. For example, you can combine the found inequalities for x to solve that x must be GREATER than 3 while being LESS than -2. Using that you can form an line and make a line. Remember, when writing in interval notation form you always begin from the left to the right (in reference) to the number line.

Help plzz (30) points for both of the question-plz help - this is life or dead answer

Elodia [21]

Answer:

The answer is B) 11.

Step-by-step explanation:

We can solve this by making an expression to represent the situation. Let x = the number of student books in the box (what we're looking for):

$2.3x + 4.3 + 0.4 = 30$

$2.3x + 4.7 = 30$

$2.3x + 4.7 - 4.7 = 30 - 4.7$

$2.3x = 25.3$

$2.3x/2.3 = 25.3/2.3$

$x = 11$

1. 48 c = __qt

Scorpion4ik [409]

Number 1:
We know that 1 quart = 4 cups. That means we need to divide 48 by 4.
What is 48 / 4=12
Number 1 is D
Number 2
We know that oz =0.0625 pounds
Well we multiply 0.0625 by 92 and get 6
Number 2 is B
Number 3
We know that 1 yd = 3 ft
We have to multiply. 3*6=18 But we have to add that one 18+1=19
Number 3 is C
Number 4
We know that 6 pounds = 96 oz from earlier and half of a pound is 8 so that means we do 96+8=104
Number 4 is A

Hope this really helped!

After all of the start-up costs, a company starts with $100 and makes $0.75 on each unit sold. Write a linear equation in slope

KiRa [710]

The answer would most likely be c because you multiply 0.75 by the amount of units sold and find out the profit after adding it.

Hope this helps! :)

Can someone answer this question and give an explanation

Temka [501]

Answer:

48cm^2

Step-by-step explanation:

First, you can break down this shape into two different, easier to work with shapes, with dimensions of 4*9 and 6*2. You can get this by cutting the bigger rectangle into the 4*9, and then using the 6*2 left over.

After that, all you need to do it multiply and then add.

4*9 is 36, and 6*2 is 12.

36+12=48

Hope this helped!
