Mimi sells super-sized cookies for $1.50 each and estimates she has expenses of $10 to make one batch of cookies. If the inequal

Jobisdone [24]

Answer:

(b) x > 26 cookies

Step-by-step explanation:

The selling price of 1 super-sized cookie, S.P.=$1.50

Let a batch have x cookies.

So, the selling price of x cookies=1.5x

The expences in making one batch of cookies=$10

So, net profit = 1.5x-10

The given inequality to model this is 1.5x - 10 > y, That means the profit for one batch is greater than y.

As she wants to make a profit of at least $30, so for this condition, the value of y is 30.

Now, the given inequality become,

$1.5x - 10 >30$

$\Rightarrow 1.5x>30+10$

$\Rightarrow x>\frac{40}{1.5}$

$\Rightarrow x>26\frac{2}{3}$

As x is the number of cookies, so, it can't have a fractional value. This can be written as

$x>26$ or $x\geq27.$

So, she has to sell more than 26 cookies to make a profit of at least $30.

Hence, option (b) is correct.

4.

x=2y
y=x-2

(Substitute)

x=2(x-2)
x=2x-4
-x=-4
x=4

Plug x=4 into both equations to find y and check

4=2y
2=y

y=4-2
y=2

(4,2)—> Blank 1:4 and Blank 2:2

5.

x=2y-3
x=2y+4

2y-3=2y+4

No solution —> Blank 1: NS and Blank 2: NS

How do i do numer 1 and 3.?!?!?!?!?!

Anna11 [10]

To solve each question, all you've got to do is add the two numbers together and then graph the result on the number line.

1.) -3 +(-1.5)
Add 3 to -1.5. It would be the same as subtracting 1.5 from -3(-3 - 1.5)
Final Answer: -4.5
Or, since you are using a number line, start on -3 and go left 1.5 units and you will land on the -4.5 point. You go to the left because you are adding a negative number..

2.) 1.5+3.5
Add
Final Answer: 5
Or, since you are using a number line, start on 1.5 and go to the right 3.5 and you will land on 5. You go to the right because you are adding a positive number.

3.) 1/4 + 1/2
Multiply 1/2 by 2 to make both fractions have the same denominator
1/4 + 2/4
Add
Final Answer: 3/4
Or, since you are using a number line, start on 1/4 and go up 2/4 and you will land on 3/4 as the result.

4.) -1 1/2 + (-1 1/2)
Add -1 1/2 to -1 1/2. This would be the same as subtracting 1 1/2 from -1 1/2(-1 1/2 - 1 1/2)
Final Answer: -3
Or, since you are using a number line, start on -1 1/2 and go to the left 1 1/2 and you will land on the -3 point.
