Answer:
Step-by-step explanation:
perimeter P= 2L+2W
360=2(L+W) divide by 2
180=L+W
we know the L=100
180=100+W
W=80
Answer:
y=-x-2
Step-by-step explanation:
The line passes through the points -2,0 and 0,-2. The line is slanted towards the left so the line has a negative slope.
equation of line with negative slope: y=mx+b
using the rise over run tactic: 2/2= 1
y=-x+b
the y intercept is 0,-2
y=-x-2
Y - 6 = 10(x - 2) hope this helps :)
Answer:
3.5kg
Step-by-step explanation:
Let original weight of grapes in box be X and weight of grapes in basket be Y.
From the first sentence
X = 2Y (weight in box = 2 times weight in basket) --- (1)
If you add 2kg of grapes to basket, the weight of grapes in basket = Y + 2
From the second statement
Y + 2 = X + 0.5
Subtracting Y from the LHS gives 2 = X - Y + 0.5
Subtracting 0.5 from both sides gives 2-0.5 = X - Y or X - Y = 1.5 --- (2)
Substituting for X from the first equation in (2) we get
2Y - Y = 1.5 or Y = 1.5kg
But this is the original weight of the grapes in the basket. Since we have added 2 kg of grapes to the original weight, we get the weight of grapes in basket now as 1.5 + 2.0 = 3.5kg
Answer:
The width is 5 because if you multiply 16 by 8 by 5 you will get 640 cubed.
