Step-by-step explanation:
In order to solve the following system of equations by subtraction, which of
the following could you do before subtracting the equations so that one
variable will be eliminated when you subtract them?
4x – 2y=7
3.x – 3y = 15
A. Multiply the top equation by 15 and the bottom equation by 7.
B. Multiply the top equation by 1/3.
O C. Multiply the top equation by 3 and the bottom equation by 4.
D. Multiply the top equation by-3 and the bottom equation by 2.
4x – 2y=7
3x – 3y = 15
we want to keep y by eliminating the x
so we will Multiply the top equation by 3 and the bottom equation by 4.
we will get
12x - 6y = 21
12x - 12y = 60
we subtract the equations
12x - 6y - 12x - (-12y) = 21 - 60
6y = -39 and so on

Caitlin won a bag full of money! She has 49 bills in all. She counts $1430. There
are twenty dollar bills and fifty dollar bills. How many of each bill does Caitlin
have? Which system best represents the situation?
20x + Soy - 1430
10x + 5y - 1430
x+y = 1430
202.50y 49
Answer:
I believe A would be the correct one, but I'm not 100% sure, none of the others make any sense and it looks like there may be a typo on A.
Step-by-step explanation:
If Caitlin were to win a huge sum of cash. In total, she has 49 bills. She adds up $1430. There are twenty and fifty-dollar bills available. The equation 20x + 50y = 1430 is the one that best describes the situation.
What is an equation?Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation.
Given that Caitlin won a bag of cash, she has a total of 49 bills. She adds up to $1430. There are twenty and fifty-dollar notes available.
The system best represents the situation is,
20x + 50y = 1430
Thus, if Caitlin was to win a huge sum of cash. In total, she has 49 bills. She adds up to $1430. There are twenty and fifty-dollar bills available. The equation 20x + 50y = 1430 is the one that best describes the situation.

a furniture company currently produces 5800 chairs per month. If production decreases 5%, find the amount of the decrease and the new number of chairs produced each month.
Answer:amount of decrease 290 ;numbers of chairs 5510
Step-by-step explanation:
Stablish the proportion 5800/100%=x/5% then solve for x. ; x=(5%/100%)*5800 = 290 which is the decrease. Then make the difference 5800-290 and you get 5510
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The number of chairs decreased is 290.
The number of new chairs produced each month is 5510.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Number of chairs produce in a month = 5800
5% decrease in production:
= 5% of 5800
= 5/100 x 5800
= 5 x 58
= 290
The number of new chairs produced each month:
= 5800 - 290
= 5510
Thus,
The number of chairs decreased is 290.
The number of new chairs produced each month is 5510.

In a properly drawn sample with a 3-percent sample error, 20% of 100 respondents indicate they intend to vote for a ballot measure. This means that there is high probability that between ______ percent of all voters actually plan to vote for the ballot measure.
The true statement is that, the probability that 17% to 23% percent of all voters planned to vote is high
How to determine the probability?The percentage sample error (S) is given as:
S = 3%
The proportion (p) of the respondent is given as:
p = 20%
This means that the range (R) of the proportion is:
R = p ± S
This gives
R = 20% ± 3%
Expand
R = (20% - 3%, 20% + 3%)
Evaluate
R = (17%, 23%)
This means that the range is 17% to 23%

In three days Alexandra sold a total of 31 tickets to her school play. On Tuesday she sold as twice as many tickets as on Wednesday. And on Thursday, she sold exactly seven tickets. How many tickets did Alexandra sell on each day Tuesday through Thursday?
Answer:
Alexander sold
8 tickets on Tuesday
16 tickets on Wednesday
7 tickets on Thursday
Step-by-step explanation:
Let us represent:
Number of tickets sold on Tuesday = a
Number of tickets sold on Wednesday = b
Number of tickets sold on Thursday = c
In three days Alexandra sold a total of 31 tickets to her school play.
a + b + c = 31...... Equation 1
On Tuesday she sold as twice as many tickets as on Wednesday.
2a = b
And on Thursday, she sold exactly seven tickets.
c = 7
Substitute 2a for b and 7 for c in Equation 1
a + b + c = 31...... Equation 1
a + 2a + 7 = 31
3a = 31 - 7
3a = 24
a = 24/3
a = 8 tickets
Note that
2a = b
a = 8 tickets
2 × 8 = 16 tickets
b = 16 tickets
Therefore, Alexander sold
8 tickets on Tuesday
16 tickets on Wednesday
7 tickets on Thursday

what similarity statement can you write relating the three triangle in the diagram?
Answer:
D.
Step-by-step explanation:
In triangle EAK, A is the right angle.
In triangle AGK, G is the right angle.
In triangle EGA, G is the right angle.
That means we know that those letters have to be in the same position in the names of the three triangle.
The triangles are being written in the order: EAK, AGK, EGA
_A_ ~ _G_ ~ _G_
Angle E of triangle EAK corresponds to angle E of triangle EGA.
EA_ ~ _G_ ~ EG_
Angle K of triangle EAK corresponds to angle K of triangle AGK.
EAK ~ _GK ~ EG_
There is only one vertex missing in the last two triangles, so they must be A and A.

Answer:
29.92 m² (nearest hundredth)
Step-by-step explanation:
[tex]\textsf{Area of a sector}=\dfrac{\theta}{360\textdegree}\pi r^2[/tex]
[tex]\implies \textsf{area}=\dfrac{30}{360\textdegree}\pi \cdot 5.5^2=\dfrac{121}{48}\pi \textsf{ m}^2[/tex]
Area of rectangle = width × length
⇒ area = 4 × 5.5 = 22 m²
Total area = area of sector + area of rectangle
