Well set it up first. You get: 8.2-(-3.5) so what you do is that you first subtract 8.2-3.5=4.7. Then you want to find out weather it is negative or positive. First point out which one is bigger in this case 8.2 is bigger and a positive so your answer would be positive. Answer: +8.2 or 8.2
Q1. The answer is To solve, you must divide both sides by 6
The equation is: 6d = 12
<span>Multiplication is the inverse operation: TRUE - 6d = 12 d = 12/6
Checking the solution involves multiplication: TRUE - 6 * 2 = 12
The equation represents the number that gives twelve when multiplied by 6: TRUE d is </span>the number that gives twelve when multiplied by 6<span>
To solve, you must divide both sides by 6: false
Q2. The answer is 18
</span><span>
x - the number of students
The students were divided equally among 3 chaperones: 3 chaperones per x
Each chaperone supervised 6 students: 1 chaperone per 6 students
3 : x = 1 : 6
x = 3 * 6 : 1
x = 18
Q3. The answer is </span><span>t is greater than or equal to five.
</span>
It will take Harlon at least five years to complete his college degree. The key word is at least. This means that it can include number 5 as well. He may need 5 years, 6 years, 7 years,... Hence, t is greater than or equal to five.
Q4. The answer is <span>1.2
</span>
<span>p over zero point three + 2 = 6
p/0.3 + 2 = 6
multiply both sides by 0.03
p + 2 * 0.3 = 6 * 0.3
p + 0.6 = 1.8
p = 1.8 - 0.6
p = 1.2
Q5. The answer is 2.
</span><span>16w = 32
Divide both sides by 16
16w/16 = 32/16
w = 2</span>
W+D=659
W=D-91
---------------------------
(D-91)+D=659
D-91+D=659
2D=750
D=750/2=375
------------------------------
W+375=659
W=284
------------------------------
So the dryer had cost $375 and the washer had cost $284.
Answer:
The equation is given below as
Step 1:
We will work on the left-hand side, we will have
By substituting the identity above, we will have
Here, we will make use of the quotient identity
Step 2:
By writings an expression, we will have
Here, we will use the definition of subtraction
Step 3:
We will apply the double number identity given below
By applying this, we will have
Here, we will use the double number identity
Multiply the sales by the commission rate and add that to the base salary.
45,000 x 0.04 = 1,800
Total pay = 1800 + 380 = $2,180
