Find the 92nd term of the arithmetic sequence -29, -22, -15, ...
Answer:
608
Step-by-step explanation:
The appropriate general formula here is a(n) = a(1) + (n -1)d, where d is the common difference. Here, d = +7. Thus:
a(92) = -29 + (92-1)(7) = 608

When 0.5(20x – 50y + 36) – 0.25(–100x + 40y – 12) is simplified, what is the resulting expression?
10x-25y+18-25x+10y-3
-15x-15y+15
-10x+25y+18+25x-10y+3
35x-35y+21
Answer:
35x-35y+21
Step-by-step explanation:
You would have to combine the like terms together to get 35x-35y+21.
By applying algebra properties we notice that the algebraic expression 0.5 · (20 · x - 50 · y + 36) - 0.25 · (- 100 · x + 40 · y - 12) is equivalent to 35 · x - 35 · y + 21. (Correct choice: D) #SPJ5
How to simplify an algebraic expressionIn this question we must simplify an algebraic expression by applying the following list of properties:
Commutative propertyAssociative propertyModulative propertyDistributive propertyExistence of additive inverseExistence of multiplicative inverseNow we proceed to simplify the expression given in the statement:
0.5 · (20 · x - 50 · y + 36) - 0.25 · (- 100 · x + 40 · y - 12) Given

Answer: 0.6 in 10 % ; 0.4 in 15 %
Step-by-step explanation:
1. (x*10%) + (y*15%)/ x+y=12%
2. x+y = 1 x= 1-y
(0.1x + 0.15y/ x+y= 12/100) * 100
(10x + 15y/x+y = 12)*(x+y)
10x+15y= 12x + 12y
-2x=-3y
2x = 3y 2(1 - y)= 3y
2-2y=3y 2= 5y
y= 0.4
x= 0.6
A long-distance delivery truck averages 8 miles per gallon when the truck is full. The
miles per gallon improves by 20% when the truck is empty. If the truck travels 160 miles
full to deliver its goods, and then travels back 160 miles empty, approximately how many
gallons will the truck use in all?
The gas used by truck is 36.66 mpg.
What is linear equation?When graphed, a linear equation always produces a straight line because it is an algebraic equation with each term having an exponent of 1. It is referred to as a "linear equation" for this reason.
One-variable linear equations and two-variable linear equations exist.
Given
A long-distance delivery truck averages 8 miles per gallon when the truck is full.
The miles per gallon improve by 20% when the truck is empty.
The distance delivery truck averages 8 miles per gallon when full, and the amount of gasoline used (g) is expressed in terms of the number of miles driven ([tex]m_{f}[/tex]).
When the truck is full, the amount of gasoline is shown as,
[tex]m_{f}[/tex] = d/8
given distance is 160 miles
[tex]m_{f}[/tex] = 160/8 = 20 mpg
Then,
The miles per gallon improve by 20% when the truck is empty.
The number of miles driven when empty is represented as,
[tex]m_{e}[/tex] = d/(8 + 1.6)
[tex]m_{e}[/tex] = d/9.6
[tex]m_{e}[/tex] = 160/9.6
[tex]m_{e}[/tex] = 16.66 mpg
total gasoline required = [tex]m_{e}[/tex] + [tex]m_{f}[/tex] = 20 + 16.66 = 36.66 mpg
Hence the total gas used is 36.66 mpg.

How do I complete the square for 4x^2+ 8x-5= 0?
Answer:
man I have no idea dude I don't really know squares if you're talking about square root I really don't know
Answer:
x = [tex]\frac{1}{2}[/tex], - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
This is not so fun!
[tex]4x^{2} + 8x - 5 = 0\\[/tex]
Step 1: Move the 5 to the right side
[tex]4x^{2} +8x = 5[/tex]
Step 2: Divide thru by 4
[tex]x^{2} + 2x = \frac{5}{4}[/tex]
Step 3: Divide 2 (from 2x) by 2 and square the result and add that to both sides of the equation.
2/2 = 1 1 squared = 1
[tex]x^{2} + 2x + 1 = \frac{5}{4} +1 = \frac{9}{4}[/tex]
Step 4: Factor the left side
[tex](x + 1)^{2} = \frac{9}{4}[/tex]
Step 5: Take the square root of both sides
x + 1 = ±[tex]\sqrt{\frac{9}{4} }[/tex] = ± [tex]\frac{3}{2}[/tex]
Step 6: Move the 1 to the right side and add the results
x = -1 ± [tex]\frac{3}{2}[/tex] = -1 + [tex]\frac{3}{2}[/tex] or -1 - [tex]\frac{3}{2}[/tex]
= [tex]\frac{1}{2}[/tex] or - [tex]\frac{5}{2}[/tex]
And bingo, you have the solutions by completing the square. Lot of fun, huh.
Taryn buys 8 identical glasses. Her total is $48 before tax. How much did Taryn pay for each pair of glasses?
Answer:
$12 per pair of glass.
$6 per glass.
Step-by-step explanation:
48/8 = 6
A pair is 2, so I multiplied 6 by 2.
6 x 2 = 12
So, Taryn paired $12 per glass.
--
ANSWER: $12 per pair
EXPLANATION: $48 divided by 8 pairs of glasses equals $6 per glasses. So then you multiply 6 by 2 to get the amount per pair.

Step-by-step explanation:
In a rhombus, all sides are congruent; they have the same lengths (like a square). This means that if this parallelogram was a rhombus, 14 - x and 2x + 8 will have to be equal.
14 - x = 2x + 8
Subtract 2x from both sides
14 - 3x = 8
Subtract 14 from both sides
-3x = -6
Divide both sides by -3
x = 2
37=-3+5(x+6), Please provide explanation.
Answer:
x=2
Step-by-step explanation:
youd distribute the 5 first so the equation is now
37=-3+5x+30
then group the common terms (-3 and 30 in this case)
37=5x+27
now subtract 27 from both sides to start to isolate 5x
10=5x
divide by 5 to find x
2=x
