Answer:
18k
Step-by-step explanation:
To solve this, you must first multiply -3 by (10+3k). This leaves you with -30-9k. Next, compare which values you need to make the two equations equal. -30=-30, but -9k does not equal 9k. So, you need to add 18k to make the equations equal.
The equation P=6s represents the perimeter P of a regular hexagon with side length s. What is the
perimeter of a regular hexagon with side length 2 mm?
The perimeter is
mm.
Answer:
The perimeter is 12mm
Step-by-step explanation:
Plug 2 for s in P=6s so 6*2=12
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.

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)

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

CHECK :

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.
