Answer:
x = -17
Step-by-step explanation:
11 - 2x = 45
We first want to subtract 11 from both sides, so that we have the variable and it's factor on its own side. Making the equation:
-2x = 34
Next, we are going to divide each side by the variables' factor, which in this case is -2. However, there is a slightly longer way to do this, but when you're doing it by hand, it is much easier. I will be showing that way below.
So, instead of dividing either side by -2, we are going to divide both sides by 2. Giving us:
-x = 17
This next step is easy peasy. Since the negative is on the variables side and we need the variable to be positive, we just switch the position of the negative to the numerical side. Shown below.
-x = 17
to
x = -17
So, our final answer is x = -17
Hope this helps!
Answer:
Step-by-step explanation:
Solution
11 - 2x = 45
or, 2x=11-45
or, 2x=-34
x=-17

An electronics company finds that 5 out of 1,535 capacitors produced are damaged. How many damaged items can they expect if the company produces 23,025 capacitors?
Answer:
the damaged items expected in the case when the 23,025 capacitors produced is 75
Step-by-step explanation:
The computation of the damaged items expected in the case when the 23,025 capacitors produced is shown below:
= (5 × 23,025 capacitors) ÷ (1,535 capacitors)
= 75
Hence, the damaged items expected in the case when the 23,025 capacitors produced is 75
The same number goes into each box to make two ratios below
4/_ ‘ _/36
Which number goes into both boxes?
A) 6
B)9
C)12
D)18
Answer:
C) 12
Step-by-step explanation:
What you are trying to find is when 4/_ = _/36. The only number that will set these two ratios equal is 12. This is because 4/12 simplifies to 1/3, and 12/36 simplifies 1/3, meaning the two ratios are equivalent.
Answer:
c

A total of 937 people attended the play.
Admission was $2.00 for adults and $0.75
for students. The total ticket sales
amounted to $1,109. How many students
and adults attended the school play?
First complete the equations below, where A
stands for Adults and S stands for Students.
2A + 0.75S = 1,109; A + S = 937
Now use the equations to find the number of
students and adults.
Students = [?]; Adults = []
Answer:
612 students and 325 adults
Step-by-step explanation:
I'll use substitution for this set of equations. I'll start with 2a + 0.75s = 1,109.
2a + 0.75s = 1,109
Subtract 0.75s from both sides.
2a = -0.75s + 1109
Divide both sides by 2.
a = 1/2(-3/4s + 1109)
Make 1/2(-3/4s + 1109) into a single fraction
a = -3/8s + 1109/2
Substitute -3/8s + 1109/2 for a in the other equation (a + s = 937).
-3/8s + 1109/2 + s = 937
Add -3/8s to s.
5/8s + 1109/2 = 937
Subtract 1109/2 from both sides.
5/8s = 765/2
Multiply both sides by 8/5, the reciprocal of 5/8.
s = 612
Now head back to the original equation, and substitute s for 612.
a = -3/8 * 612 + 1109/2
Multiply -3/8 by 612.
a = (-459 + 1109)/2
Add 1109 to -459 and divide by 2.
a = 650/2
a = 325
The system is solved. There are 612 students and 325 adults.

Which of the following shows the solution and graph to the inequality
2x + 1 ≤ 15?
Answer:
C or D
Step-by-step explanation:
I'm taking this same thing, not sure if it's c or d. The thing that I'm puzzled about is what the difference between the white dot and the black dot is.
Option D shows the solid dot along with [tex]x\leq 7[/tex] so our answer is
Option D.
The given inequality is 2x + 1 [tex]\leq[/tex] 15.
We have to see which of the given option shows the solution and graph to this inequality.
What are a solid dot and an open dot?A solid dot indicated on a number line graph shows that the given number is also a possible solution, whereas an open dot indicates that the given number cannot be a solution.
We see that in the given inequality, 2x + 1 must be less than or equal to 15.
And the maximum value we can take is 7 because,
2(7) + 1
14 + 1
15
So we can take 7 and any values less than 7 i.e [tex]x\leq 7[/tex] to satisfy the inequality 2x + 1 [tex]\leq[/tex] 15.
We see that Option D gives us [tex]x\leq 7[/tex] along with the solid dot.
Hence Option D is our answer.

what expression can be used to determine the cost of the buying and pounds of almonds $4.95 per pound and a half pounds of flour for $0.72 per pound? choose the correct expression for determining the cost please
A: 0.72m + 4.95f
B: 5.67(m=f)
C: 4.95m + 0.72f
D: 4.95m - 0.72f
I think it is C: 4.95m + 0.72f although this isn't in my curriculum I think its correct.
if anyone is willing to, please help me with this? Thank you .
Answer:
divide the cost by the amount.
4.95/5 = 0.99
8.50/10 = 0.85 (better buy)
3.59/3 = 1.20
4.99/5 = 1.00 (better buy)
1.25/16 = 0.078125
1.55/20 = 0.0775 (this one is the better buy however when you round to 2dp they are both the same price of 0.08.)
