When you square a negative number, the result is positive.
(-4)^2 = (-4)ª(-4) = 16
When you cube a negative number, the result is negative.
(-4)^3 = (-4)•(-4)•(-4) = -64
Negatives pair up and cancel out, so odd exponents always have one negative unpaired, making the result negative.
The baker can decorate
42/30,
which would mean 42 cupcakes in 30 minutes,
and then you would get
1.4 cupcakes per minute.
Hope this helps and have a nice day:)
16/155 = n
explanation
A linear equation is an equation of a straight line. To solve linear equations, it is important to keep the following key concepts in mind:
Maintain balance of the equation by applying the same operations to both sides of an equation
Isolate for the variable by collecting like terms
Use inverse operations to rearrange an equation
to show your work
-8/ 5 = -31/2 • n
- 8/5 = -31n/2
2(-8/5) = 2 • -31/n
-16/5 = -31n
-16/5 / -31 = -31n/31
16/155 = n
Answer:
Step-by-step explanation:
Length of the rectangle given in the the figure attached = 2 cm
Width of the rectangle = 5 cm
Scale used, 24 in to 1 cm
Therefore, length of actual rectangle = 2×24 = 48 in
width of the actual rectangle = 5×24 = 120 in
Now we have to draw a drawing by using the scale,
16 inches to 1 cm
Or 1 inch = 
cm
Therefore, length of the rectangle drawing = 
= 3 cm
Similarly, width of the rectangle drawing = 
= 7.5 cm
