Answer:
Option D. All values of x make the equation true
Step-by-step explanation:
<u><em>The options of the question are</em></u>
a.The result is not correct because Step 2 has an error.
b.The solution is x=7.
c.No values of x make the equation true.
d.All values of x make the equation true
we have the equation
solve for x
Apply distributive property right side
Combine like terms
subtract 4x both sides
The equation has infinity solutions
.All values of x make the equation true
Answer:
The powdered drink mixes is a better price per gallon on lemonade produced.
Step-by-step explanation:
The powdered drink mixes is a better price per gallon on lemonade produced because of the following reasons listed below:
The cost price to produce lemonade for the powdered mixes goes for $1.79 each for 2 gallons which is lesser and cheaper and much more affordable compared to cost of preparing the lemonade from fresh lemons
The cost of buying fresh lemons which is calculated to cost
$0.39 for 1 lemon which means for 10 lemons, the cost would be
10 × $0.39 = $3.9
1 pound of sugar cost $2.99
The total cost price would be
$3.9 + $2.99
= $6.89
When we compared the both prices and check the calculation shown above, we can see that the powdered mixes is a much better option and much better price per gallon of lemonade purchased.
X = 12
because if you notice, each of the angles have a little arc in the corner, which means they are congruent. if all three angles are congruent, that means each angle is 60° because each triangle has a maximum value of 180°. therefore, this means it is an equilateral triangle.
that being said, each side must be equal as well. so, you can use any two sides to find x by using each one on a different side of an equation, then isolating and solving.
5x - 22 = 3x + 2 = 4x - 10
so
5x - 22 = 3x + 2
3x + 2 = 4x - 10
4x - 10 = 5x - 22
whichever one you solve for, x = 12. and if you plug in that number for x, each side equals the same number = 38
I believe its B. The amount if money she makes is a function of the number of hours she works. Hope this helps!!
