Answer:
Step-by-step explanation:
35 a + 34 b = 163.50 (given)
15 a + 17 b = 76.50 (given) multiply this equation by -2
-30 a - 34 b = -153.00 now add this equation to the first equation t get
5 a = 10.50 solve this for a (apple's price) then sub this value into one of the equations to find banana price, b.

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
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%

-5a + 15/2a - 25 = 53.2 + 21.8
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

You need to write an essay that has at least 700 words. You have written 300 words so far. Write an inequality that represents the number of words w that you have left to write.
Answer:
300 + w ≤ 700
Step-by-step explanation:
It would not be 300 + w = 700 because you have to write at least 700 words, so 300 + w must be equal to or greater than 700, and the equal to or greater than sign is ≤

Explain! Prizes! Thank you !
Answer:
$16
Step-by-step explanation:
20/5 = 4
4 x 4 = 16
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
Deshawn's Bikes rents bikes for $11 plus $5 per hour. Maria paid $51 to rent a bike. For how many hours did she rent the bike?
If h(x) = 5 + x and (x) = 5. which expression is equivalent to (k-1)(o)? (5+) 1 (5+) 5+ 5+ (5 + x)
(5+x)/x
K*H = 1/x(5+x) or (5+x)1/x which = (5+x)/x because (5+x)1/x = [(5+x)/1] * [1/x] and anything multiplied by one is equal to itself.
If h(x) = 5 + x and k(x) = 5 then the expression which is equivalent to (koh)(x) is 25+5x
What is a function?A relation is a function if it has only One y-value for each x-value.
The given functions are h(x) = 5 + x and k(x) = 5x
We have to find the expression which is equivalent to (koh)(x)
(koh)(x) = k(h(x))
=k(5+x)
Now we have to plug in 5+x in the function k(x)
k(5+x)=5(5+x)
=25+5x
Hence, if h(x) = 5 + x and k(x) = 5 then the expression which is equivalent to (koh)(x) is 25+5x

FIND VALUE OF X AND OF ANGLE ABC AND ACD
PLS HELP
GEOMETRY
Answer:
see explanation
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ ACD is an exterior angle of the triangle, thus
43 + 5x - 48 = 3x + 57 , that is
5x - 5 = 3x + 57 ( subtract 3x from both sides )
2x - 5 = 57 ( add 5 to both sides )
2x = 62 ( divide both sides by 2 )
x = 31
Thus
∠ ABC = 5x - 48 = 5(31) - 48 = 155 - 48 = 107°
∠ ACD = 3x + 57 = 3(31) + 57 = 93 + 57 = 150°
can someone help..convert 15/125 to a decimal in long division?
Answer:
the answer is 0.12
Step-by-step explanation:
You would do 15/125 which is 3/25
then you would do 25 times 4 and the 3 times for to get 12/100
then you would convert that into a decimal which is 0.12

Answer:
x = 11Step-by-step explanation:
The equation represents as:
285 − 5x = 340 − 10x
combine similar terms:
285 - 340 = 5x - 10x
simplify:
-55 = -5x

x = 11
The sum of 3 consecutive odd integers is 36. Whal
consecutive odd integers
[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.
