Answer:
x + 5y = 22.45
x + 7y = 25.45
Step-by-step explanation:
Given:
Customer A oil tank size = 5 quart
Customer B oil tank size = 7 quart
Total cost for A = $22.45
Total cost for B = $25.45
Find:
Equation
Computation:
So,
x + 5y = 22.45
x + 7y = 25.45
\begin{aligned} A.&&3(x+2)&=18 \\\\ B.&&3x+6&=18 \end{aligned} A. 3(x+2) =18 B. 3x+6 =18
1) How can we get Equation BBB from Equation AAA?
[tex]\huge\textbf{Use the distributive property.}[/tex]
[tex]\begin{aligned}A.&&3(x+2)&=18\\ B.&&3x+6&=18 \end{aligned}[/tex]
You can use the distributive property to get equation B from equation A.
The distributive property proves that [tex]a(b+c)=ab+ac[/tex]. Use this same logic on equation A, distributing [tex]3[/tex] to [tex](x+2)[/tex].
[tex]\begin{aligned}3(x+2)&=18\\3x+3(2)&=18\\3x+6&=18\end{aligned}[/tex]
the sum of 26 and twice a number is -46 find the number
Answer:
-72
Step-by-step explanation:
Sum is adding so I just did substitution for this. 26+-72=-46 because a positive plus a negative equals a negative.

For the concert, 109 adult tickets were sold. 67 more tickets were sold for students than for adults. How many tickets sold in total?
Answer:
285 I believe
Step-by-step explanation:
109 + (109 + 67) = total
109 + 176 = total
total = 285
A total of 285 tickets were sold for the concert.
What is the addition operation?The addition operation in mathematics adds values on each side of the operator.
For example 4 + 2 = 6
If 67 more tickets were sold for students than for adults, then the number of student tickets sold can be calculated as follows:
109 adult tickets + 67 = 176 student tickets
So, the total number of tickets sold is:
109 adult tickets + 176 student tickets
Apply the addition operation, and we get
= 285 tickets in total
Therefore, a total of 285 tickets were sold for the concert.

A botanist measures a plant, in feet, at the beginning of each month and notices that the measurements form a
geometric sequence, as shown below.
2, 2.2, 2.42, 2.662, ...
If the first measurement was taken on September 1, about how tall was the plant three months before, on June 1,
assuming the same growth pattern?
0.9 ft
1.5 ft
1.7
2.0 ft
Answer:
1.5ft , B for EDGE2020
Step-by-step explanation:
they are being multiplied by 1.1, so if you divide 1.1 down from 2 three times you get 1.5 roughly.
Using a geometric sequence, it is found that the plant's height on June 1 was of 1.5 ft.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem, we have that the first term and the common ratio are given, respectively, by:
[tex]a_1 = 2, q = \frac{2.2}{2} = 1.1[/tex]
Hence the rule for the nth term is given by:
[tex]a_n = 2(1.1)^{n-1}[/tex]
June 1st would be equivalent to three months before the term 1, hence it is the term 1 - 3 = -2, then:
[tex]a_{-2} = 2(1.1)^{-3} = 1.5[/tex]
The plant's height on June 1 was of 1.5 ft.

Answer: XY=21 YZ=29
Step-by-step explanation: okay so the entire line (XZ) is equal to 50, and its made up of a and a + 8. So you can make an equation out of that.
a+a+8=50
2a+8=50
2a=42
a=21
then you just have XY equal 21, and YZ equal 21+8 or 29.
Answer:
XY = 21
YZ = 29
Step-by-step explanation:
XZ = 50
XY = a
YZ = a + 8
XY + YZ = XZ
a + (a + 8) = 50
2a + 8 = 50
2a = 50 - 8
2a = 42
a = 42 ÷ 2
= 21

Answer:
325.
Step-by-step explanation:
200/x=100/162.5
(200/x)*x=(100/162.5)*x - we multiply both sides of the equation by x
200=0.61538461538462*x - we divide both sides of the equation by (0.61538461538462) to get x
200/0.61538461538462=x

Mental accounting can be used to explain(A) higher savings in separate retirement accounts;(B) high willingness to spend on credit cards;(C) holding depreciating stocks longer than appreciating ones;(D) all of the above.
Answer:
(D) all of the above.
Step-by-step explanation:
Mental accounting refers to this ability to organize your budget, to think about your money by separating it into different expenditure items. Your brain differentiates money based on how you got it and how you plan to spend it. In other words, you are creating some sort of mental piggy bank where you put your money which will be used for such and such an expense.
Mental accounting can be used to explain how higher savings are derived with various retirement accounts; how high clients purchasing a particular product are willing to spend on credit cards and also explains why brokers hold depreciating stocks longer than appreciating ones due to the mental thought that such depreciating stock will rise at a future time.
