Answer:
X >= 7
Step-by-step explanation:
7x + 8 >= 57
7x >= 57-8
7x >= 49
x >= 49/7
x >= 7
The expression which is:
3.28 + 3.28 + 3.28 = 9.84
Is simply equivalent to the expression of thrice the value
of 3.28 is equal to 9.84 or:
3 x 3.28 = 9.84
<span>The two are simply equal since in the 1st
expression there are three 3.28 and in the 2nd expression there are
also three 3.28.</span>
Answer:
x = 60 cents.
Step-by-step explanation:
The man wants to make up 100 one-pound jars of nuts, it means he will need 100 pounds of nuts. He plans to use 40 pounds of one type of nuts, so he needs 60 pounds of the other type of nuts to get 100 pounds.
Now, with this we can write a linear equation:
(40*0.75)+(60*x) = 100*0.66 (1)
Where:
- 0.75 is the unit price of the 40 pounds of one type of nuts.
- x is the unit price of the 60 pounds of the other type of nuts.
- 0.66 is the unit price of 100 one-pound jars.
Let's solve the equation (1) for x:
Therefore, x = 60 cents.

Addition
Subtraction
So we will complete this equation in that order. So first is solving the problem within the <u>parenthesis:</u>
<em>(12)</em> ÷ 4 · 7 - 4² ÷ 4 =?
Then we solve all the parts including an <u>exponent:</u>
12 ÷ 4 · 7 - <em>16</em> ÷ 4 = ?
Next, we solve the parts with<u> multiplication: </u>
12 ÷ <em>28</em> - 16 ÷ 4 = ?
Then, we solve for all the <u>division:</u>
<em>0.43</em> - <em>4</em> = ?
If there was any addition we would do that next, but because there is none, we move onto<u> subtraction:</u>
0.43 - 4 = -3.57
So, your <u>answer</u> is -3.57
Value of a = 3
Value of a + b = 3 + (-2/3)
Value of a + b = 2 1/3
Difference = 3 - 2 1/3
Difference = 2/3
