6 minutes because 6 x 2 is 12.
Y=mx+b
m=slope
b=y intercept
we are given (3,-1)
one solution is x=3 and y=-1 or
when x=3 then y=-1
also slope=2
so
y=2x+b
subsitue 3 for x and -1 for y and solve for b
-1=2(3)+b
-1=6+b
subtract 6
-7=b
y=2x-7 is equation
answer is number 4
Answer:
<h2>The scale is 1 inch rep 4 feet or </h2><h2>1:4</h2>
Step-by-step explanation:
This problem is on ratios, the ratio of one quantity to another is a way to represent their relative size.
Moreso, the scale of a drawing tells us to what extent the drawing has been increased (maximized) or decresed (minimized)
now given that the actual dimention of the appartmentis 28ft wide
and on the drawing the apartment is 7 inches wide, we can see that the actual dimension has been reduced by a factor of 28/7= 4
hence the scale to represent this reduction is
1 inch to represent 4 feet
Answer:
number of trousers=14
numbers of pairs of stockings=71
Step-by-step explanation:
Pairs of stockings: x
T shirt: y
Trouseres: z
7x=3y
1z=1y+2×
__________________________________________
m: number of trousers
m*z=26y
m*(y+2x)=26y
m*(y+2(3y/7))=26y
m=26y/(y+2(3y/7))
m=14
You need to buy 14 trousers that represents the equivalent of 26 T-shirts.
__________________________________________
k:pairs of stockings
k*x=10y+11z
k*x=10(7x/3)+11(y+2x)
k*x=10(7x/3)+11((7x/3)+2x)
k=71
You need to buy 71 pairs of stockings with an amount equal to the price of 10 T-shirts and 11 trousers
