The equation 285−5x=340−10x represents the situation.
Which does the variable x represent?
Will Give Brainliest
Answers
285-5x-(340-10x)=0
-5x-(-10x+340)+285=0
-5x+10x-340+285=0
5x-55=0
5x=55
x=55/5
x=11
Answer:
x = 11Step-by-step explanation:
The equation represents as:
285 − 5x = 340 − 10x
combine similar terms:
285 - 340 = 5x - 10x
simplify:
-55 = -5x
divide -5 on both sides:
x = 11

Someone invested some money at 8% and $300 more than
twice this amount at 12%. Her total annual income from
the two investments is $548. How much is invested at
each rate?
32
Answers
Answer:
$1600 at 8% and 3500 at 12%
Step-by-step explanation:
The rule of the interest is I = PRT, where
P is the amount of investment R is the rate in decimalT is the timeAssume that the amount of money is $x
∴ P = x
∵ The rate is 8%
∴ R = 8/100 = 0.08
∵ She has an annual income
∴ T = 1
→ Substitute them in the rule to find the interest amount
∴ I = x × 0.08 × 1
∴ I = 0.08x
∵ She invested $300 more than twice the previous amount
∴ P = 2x + 300
∵ The rate is 12%
∴ R = 12/100 = 0.12
∵ T = 1
→ Substitute them in the rule to find the other interest amount
∴ I = (2x + 300) × 0.12 × 1
∴ I = 0.24x + 36
∵ Her total annual income from both investments is $548
→ Add the two amount of interest and equate their sum by 548
∴ 0.08x + 0.24x + 36 = 548
→ Add the like terms in the left side
∴ 0.32x + 36 = 548
→ Subtract 36 from both sides
∴ 0.32x + 36 - 36 = 548 - 36
∴ 0.32x = 512
→ Divide both sides by 0.32
∴ x = 1600
∴ She invested $1600 at 8%
→ Substitute x by 1600 in the expression of the other amount to find it
∵ 2x + 300 = 2(1600) + 300 = 3500
∴ She invested $3500 at 12%

The sum of 3 consecutive odd integers is 36. Whal
consecutive odd integers
Answers
[tex]\huge\pink{Answer}[/tex]
Any odd number can be represented with 2n+1 where n is a whole number. Also, since the next consecutive number will be even (2n+1+1), then the next consecutive odd number must be 2n+1+2, or 2n+3. Since consecutive odd numbers are separated by 2, then the previous odd number should be 2n-1. So:
2n-1+2n+1+2n+3=366n+3=366n+3-3=36-36n/3=33/32n=11Now in order to find three odd consecutive numbers that will sum to 36, you must be able to divide 11 evenly by 2, and have a whole number as a result. This is impossible, so there aren't any 3 odd numbers that will sum to 36.

Answer: terminating repeating decimal
Step-by-step explanation: In the subject of Mathematics, we usually classify numbers in several types: whole numbers, rational numbers, natural numbers, and real numbers. We also include decimals in these types. Decimals are used by us to convey a whole number and a fraction together. We do this by separating a whole number from the adjoining fraction by inserting “.” between them. This symbol is called a decimal point. In other words, decimals are just another way of representing fractions.

-5a + 15/2a - 25 = 53.2 + 21.8
Answers
Answer:
a= 40
Step-by-step explanation:
-5a + 7.5a - 25 = 53.2 + 21.8
add like terms on both sides: 2.5a - 25 = 75
add 25 on both sides: 2.5a = 100
divide both sides by 2.5: a = 40
Answer:
a = 40
Step-by-step explanation:
-5a + 15/2a - 25 = 53.2 + 21.8: Add 25 to Isolate variable
-5a + 15/2a = 53.2 + 21.8 + 25: Combine Like Terms and create simmilar terms
-10/2a + 15/2a = 100: CLM again
5/2a = 100: multiply both sides by inverse of 5/2 to isolate variable
a = 40

Have a good day!
==================================================
Work Shown:
5 notebooks = 20 dollars
5/5 notebooks = 20/5 dollars ..... divide both sides by 5
1 notebook = 4 dollars ..... unit rate
4*(1 notebook) = 4*(4 dollars) .... multiply both sides by 4
4 notebooks = 16 dollars
---------------
Another approach:
(5 notebooks)/(20 dollars) = (4 notebooks)/(x dollars)
5/20 = 4/x
5*x = 20*4 ... cross multiply
5x = 80
5x/5 = 80/5 .... dividing both sides by 5
x = 16
So 4 notebooks cost $16
