Carlos would need to buy 4 cartons because a liter is 1000 ml. He needs 2000 ml/500 = 4
Answer:
x = -3
y = 7
Step-by-step explanation:
x + 3y = 18
-3x - 12y = -75
multiply first equation by 4
4 × (x + 3y) = 18 ➡ 4x + 12y = 72
now add the two equations up
4x + 12y - 3x -12y = 72 - 75 (-12y will eliminate 12y)
x = -3
Answer:
0.2
Step-by-step explanation:
i dont know but i think
If we round each of these numbers Then we get a good estimation
128.2 rounds out to be 130
129.11 rounds out to be 130
132.5 rounds out to be 130
So now we just add these rounded numbers up.
130 + 130 + 130 = 390
So our answer is 390
when in doubt, eat a pineapple, trust me it helps. :)
Maddison bought 2 oranges which cost ($.60 x 2 = $1.20) $1.20 total. Ronald bought 4 apples which cost ($.50 x 2 = $2.00). Now if we compare the difference between how much Ronald and Madison have spent so far we see that Ronald has spent $.80 more than Madison ($2.00-$1.20 = $.80). That means that Madison has $.80 more cents to spend on bananas than Ronald. We know that Madison buys 2 more banana than Ronald. So 2 bananas must cost $.80 cents. Divide the 80 cents by the 2 bananas and you figure out that each banana costs $.40 cents. ($.80 / 2 = $.40). To check that this math is correct next add $.40 cents for each banana to the amount of the other fruits they bought. So Madison bought 2 oranges ($1.20) and 3 bananas($.40 x 3 = $1.20) which together costs $2.40 total ($1.20 + $1.20). Ronald bought 4 apples ($2.00) and 1 banana ($.40) which together cost $2.40 ($2.00 + $.40 = $2.40. We can see that if the bananas cost $.40 cents each, Madison and Ronald will end up spending the same amount.
