16.1 – (–14.7) explain your work
Please help
Answer:
1.4 or 30.8
Step-by-step explanation:
1.4 is for regular math because it's basically 16.1 - 14.7
30.8 is for KCO or Keep Change Opposite (Beginners math)
Basically it would turn the equation into 16.1 + 14.7
You can use either but if you aren't sure ask your teacher about the strategy.
Hope this helps and if not tell me your strategy.

Step-by-step explanation:
Determine the coordinates of the point shown.
A coordinate grid shown. There are increments of 0.5 for each grid line on each of help will give brainliest .the two axes. A point is located at 3 grid lines to the right and 1 grid line down from the origin.
(1.5, −0.5)
(−0.5, 1.5)
(3, −1)
(1, −1)
x first so five to the left so it's negative and if each gridline is .5 and were are 5 gridlines aver then .5*5 so -2.5 then y is up so positive and 3 lines so .5*3 so 1.5 so coordinate is (-2.5,1.5)
Answer:the answer is B or (1.5,-.5)

Lindsay used two points x,y and x2, y2 to the equation of the line y= mx +b that passes through the points first she used the definition of slope to determine that the value of m is y2-y1/x2-x1. given this information which expression must represent the value of b?
Answer:
its A
Step-by-step explanation:
can pls have brainiest
Answer:
y2−
y1
x2
−x1
=
x2y2−x3−y
x2
Step-by-step explanation:
Let's solve for b.
y=mx+b
Step 1: Flip the equation.
mx+b=y
Step 2: Add -mx to both sides.
mx+b+−mx=y+−mx
b=−mx+y
Answer:
b=−mx+y

The length of the rectangle is
cm and the width of the rectangle is
cm
The area of a rectangle is 82.84 square meters. If the length is 7.6 meters, then what is the width?
hey i need help, anyone i don't get it do i divide or multiply HELPPPPP
Answer:
The answer is 10.9
Step-by-step explanation
#1 think of the formula of the area
length x width = area
#2 do the oposite of what you would to to find the area to find the width
82.84➗7.6 = 10.9
#3 check your answer
7.6 x 10.9 = 82.84
#3 answer
width= 10.9

If y varies directly with x, and y = 2 when x = −4, what is the value of y when x = 20 ?
Answer:
y=kx
2=k.-4
k=-1/2
then
y=-1/2×20
y=-10
Answer:
y = - 10
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = - 4, that is
2 = - 4k ( divide both sides by - 4 )
[tex]\frac{2}{-4}[/tex] = k, that is
k = - [tex]\frac{1}{2}[/tex]
y = - [tex]\frac{1}{2}[/tex] x ← equation of variation
When x = 20, then
y = - [tex]\frac{1}{2}[/tex] × 20 = - 10

A window-washing crew can finish 15 windows in 18 minutes.
If this crew was assigned to wash all of the 24,348 windows on the outside of the Burj Khalifa at this rate, how long will the crew be washing at this rate?
Answer:
34321.2 min
Step-by-step explanation:
The Burj Khalifa has in total 28601 windows. On the other hand, we are told the window-washing crew can wash 15 windows in 18 minutes. So, we can use the Rule of three to solve this problem:
If:
15 windows ---- 18 min
28601 windows ---- ?
Then:
? = (28601windows)(18min)/15windows
? = 34321.2min
Answer:
34321.2 min
