Answer:
There are no real number solutions to this.
Step-by-step explanation:
x + y = 27
xy = 365
y = 365/x
x + 365/x = 27
x^2 + 365 = 27x
x^2 - 27x + 365 = 0
x = [27 +/- sqrt(27^2 - 4 * 1 * 365)] / 2
x = (27 +/- sqrt (-731)/2
- No real roots.

Step-by-step explanation:
9 times 15+8+37=180
180 is a full line
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex](9s + 8)° + 37° = 180°[/tex]
Because they make straight line.
[tex]9s + 8 + 37 = 180[/tex]
[tex]9s + 45 = 180[/tex]
Subtract sides 45
[tex]9s + 45 - 45 = 180 - 45[/tex]
[tex]9s = 135[/tex]
Divide sides by 9
[tex] \frac{9s}{9} = \frac{135}{9} \\ [/tex]
[tex]s = 15[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
CHECK :
[tex]9(15) + 45 = 180[/tex]
[tex]135 + 45 = 180[/tex]
[tex]180 = 180[/tex]
Thus the solution is correct .

Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers
cost $0.05 each. How much would Mrs. Algebra's single order be? Use the expression below
to calculate the total.
Given :
Calculators cost $12.99 each, rulers cost $0.49 each, pencils cost $0.10 each, and erasers cost $0.05 each.
To Find :
How much would Mrs. Algebra's single order be.
Solution :
Total price paid by Mrs. Algebra = Price of pencil + price of ruler + price of calculator + price of eraser.
T = $(0.10 + 0.49 + 12.99 + 0.05)
T = $13.63
Therefore, Mrs. Algebra's single order cost is $13.63 .
Hence, this is the required solution.

only simplify, don’t solve please. thank you!
Answer:
4x
Step-by-step explanation:
the -8 and +8 cancel out
x and 3x are both positive so add them
you're left with 4x
Simplifying is the same as solving this question. I'll give steps instead.
x - 8 + 3x + 8
x + 3x - 8 + 8 (Arrange the equation)
(x + 3x) (- 8 + 8) (Parentheses the like terms together)
(4x) (0) (Solve)
4x (Simplified)

What distance would you travel in 2.5 hours if you are biking with the speed of 6.3 mph?
Answer:
15.75 milesStep-by-step explanation:
Step one:
given
time= 2.5 hours
speed= 6.3mph
Step two:
Required
Distance
we are given the speed in miles per hour, hence the distance will be in miles
we also know that the expression relating speed, distance and time is given as
speed= distance/time
thus
distance= speed*time
distance= 6.3*2.5
distance= 15.75 miles
By using expression for the speed, distance traveled by me in 2.5 hours will be
Given in the question,
Speed = 6.3 mphTime for travelling = 2.4 hoursExpression for the speed of an object is given by,
Speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]
Therefore, Distance = Speed × Time
By substituting the values of speed and the time in the expression,
Distance traveled = 6.3 × 2.5
= 15.75 miles
Therefore, distance traveled by me in 2.5 hours will be 15.75 miles.
