Answer:
53$
Step-by-step explanation:
They tell you the equation of how much the coin is worth after x amount of years
Step 1: Substitute x=19 into the equation y=2x+15
y = 2(19) + 15
Step 2: Solve for y
y = 2(19) + 15
y = 38 + 15
y = 53
Therefore the coin is worth 53 dollars after 19 years
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>
Answer:
(x-6)(x+2)
Step-by-step explanation:
Use FOIL to check if the factors work.
x * x = x²
(x * 2) + (x * -6) = 2x - 6x = -4x
-6 * 2 = -12
Answer:
$27.59
Step-by-step explanation:
1) First we calculate the sales tax:
30 x .15 = 4.5
30 - 4.5 = 25.5
2) Now we calculate sales tax
25.5 x .082 = 2.09
25.5 + 2.09 = $27.59
