Answer:

Infinite Many Solutions

0 = 0

Step-by-step explanation:

7x + 5 = 3(2x + 3) + x - 4 (Given)

7x + 5 = 6x + 9 + x - 4 (Distributive Property Of Equality)

7x + 5 = 7x + 5 (Combine Like Terms)

0 = 0 (Subtraction Property Of Equality)

As you see it's the same thing in both sides and if you solve it gives 0 = 0 because it would cancel each other out and since 0 is equal to 0 it's infinite many solutions.

PART A

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

So for 2 pounds, it would cost $5.00

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

For the 1 pound one, it would cost $2.50

PART B

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb

Let a = 2i + 3, b= i – 1, and c= -3i + 2. Which expression is equivalent to a -b- c?A. –2i +4B. 4i + 2C. 4i + 4D. -2i + 2

34kurt

Given:

$\begin{gathered} a=2i+3 \\ b=i-1 \\ c=-3i+2 \end{gathered}$

You know that:

$a-b-c=(2i+3)-(i-1)-(-3i+2)$

In order to solve the operation, you can follow these steps:

1. Distribute the negative signs. Remember the Sign Rules for Multiplication:

$\begin{gathered} +\cdot+=+ \\ -\cdot-=+ \\ +\cdot-=- \\ -\cdot+=- \end{gathered}$

Then:

$=2i+3-i+1+3i-2$

2. Combine the like terms (add the Real Parts and add the Imaginary Parts):

$=4i+2$

Hence, the answer is: Option B.

At a cake sale, David bought 3 cakes and paid $10.50. At the same price, Lisa bought 4 cakes and 8 cookies and paid $14.80. What

Olin [163]

Price of a Cake

10.5/3= 3.5

1 Cake = $3 and 5 cents, 3.5

Price of a cookie

3.5*4=14

14 out of 14.80 was the cost of 4 cakes

Which leaves us with 0.8

8/0.8= 0.1

The Price of 1 cookie is 0.1

1 Cake: 3.5

1 Cookie: 0.1
