Let us assume that the weight of carrots is "X" kilogram
Since the total weight is 9 kilograms, the weight of potatoes should be "9-X" kilograms.
The cost of "X" kilograms of carrot at $0.75/kilogram is calculated as = 0.75*X = 0.75X
The cost of "9-X" kilograms of potatoes at $0.70/kilogram is calculated as 0.70*(9-X)
We know that the total cost is $6.60
We now frame the equation as:
0.75X + (9-X)*0.70 = 6.60
0.75X + 6.30 -0.70X = 6.60
0.05X = 0.30
X = 0.30/0.05 = 30/5 = 6
Therefore weight of carrots = 6 Kilograms and
Weight of potatoes = 9-6 = 3 Kilograms

4 pizzas.
8 slices each.
That means you have 8 four times.
8 x 4= 32.
Your answer is 32.
Answer:
length: 16 m; width: 13 m
Step-by-step explanation:
Write each of the statements as an equation. You know that the formula for the perimeter is ...
P = 2(L +W)
so one of your equations is this one with the value of P filled in:
• 2L + 2W = 58
The other equation expresses the relation between L and W:
• L = W +3 . . . . . . . . the length is 3 meters greater than the width
There are many ways to solve such a system of equations. Since you have an expression for L, it is convenient to substitute that into the first equation to get ...
2(W+3) +2W = 58
4W +6 = 58 . . . . . . . simplify
4W = 52 . . . . . . . . . . subtract 6
W = 13 . . . . . . . . . . . .divide by 4
We can use the expression for L to find its value:
L = 13 +3 = 16
The length is 16 meters; the width is 13 meters.
It is B the only one that show proportionality
