In this question, you're solving for y:
Solve for y:
-3(4y - 7) - y = -2(y - 2)
<em>use the distributive property:</em>
-12y + 21 - y = -2y + 4
<em>combine like terms:</em>
-13y + 21 = -2y + 4
<em>add 2 to both sides</em>
-11y + 21 = 4
<em>subtract 21 from both sides</em>
-11y = -17
<em>divide both sides by -11</em>
y = 17/11
You would check your answer by plugging in 17/11 to the y variables.
we are given
we can move 10 on right side
we cancel -1
we can rewrite right side
we can compare exponents
and we get
.............Answer
Answer:
you would need to divide by how many number there is basically just dividing by how many numbers there are
Step-by-step explanation:
Answer:
The employee earned a total of $1004.40 dollars in commissions this week
Step-by-step explanation:
Times the number of televisions (36) by there cost ($620)
That will give you $22320
Then time $22320 by 0.045 which will give you $1004.40
Hope that helps
We want to see how much the population of goats grows each year. We will see that the correct option is c: 17%.
<h3>
Exponential growth of populations</h3>
We know that:
- The initial number of goats is 1,500.
- After 11 years, the population is 8,400.
The population can be modeled with an exponential equation as:
P(t) = A*(1 + r)^t
Where:
- A is the initial population.
- r is what we want to find, it depends on how much the population increases.
- t is the time in years.
So we have:
P(t) = 1500*(1 + r)^t
And we know that after 11 years the population is 8,400, so we have:
P(11) = 1500*(1 + r)^11 = 8400
Now we can solve this for r:
(1 + r)^11 = 8400/1500 = 5.6
(1 + r) = (5.6)^(1/11) = 1.17
r = 1.17 - 1 = 0.17
r = 0.17
To get it in percentage form, you just need to multiply it by 100%
0.17*100% = 17%
This means that the population increases a 17% each year, so the correct option is c.
