Answer:
5
Step-by-step explanation:
The equation 
is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format 
, such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,
The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation is given in the slope-intercept form, and the coefficient (
) equals (
), therefore the slope is ().
Z varies inversely as w ⇒ z*w=k
z=40 , w=0,1 ⇒40*0,1=4=k
z*20=4
z=4/20=1/5
z=0,2
Answer: the answer is 190 to the power of 7
Step-by-step explanation:
so u just have to multiply by 35 and u will get the answer
-- The smallest perimeter you can make with a certain area
is a circle.
-- The NEXT smallest perimeter with the same area is a square.
With 1-ft by 1-ft square bricks, the shortest perimeter she could
make would be by using her bricks to make it as square as possible.
Without cutting bricks into pieces, the best she could do would be
(13 bricks) x (3 bricks) .
= (13-ft) x (3-ft)
Perimeter = (2 x length) + (2 x width)
= (2 x 13-ft) + (2 x 3-ft)
= (26-ft) + (6-ft) = 32 feet <== shortest perimeter.
-- Then, the more UNSQUARE you make it, the more perimeter
it takes to enclose the same area. That means Mary has to make
a rectangle as long and skinny as she can.
The longest perimeter she can make (without cutting bricks into
pieces) is (39 bricks) x (1 brick) .
= (39-ft) x (1-ft) .
Perimeter = (2 x length) + (2 x width)
= (2 x 39-ft) + (2 x 1-ft)
= (78-ft) + (2-ft) = 80 feet .
What she'll have then is a brick path, 39 feet long and 1 foot wide,
and when you walk on it, you'll need to try hard to avoid falling off
because it's only 1 foot wide.
Answer:
I can't see the options of steps you have but here is my answer. First step is to subtract 60 from both sides so that leaves you with -3b= 60-27.
