Answer:

Step-by-step explanation:

Subtract 3x from both sides:


Well let's see. Your -gon has 35 vertexies. You use one of them
to start all the diagnals from. That leaves (35 - 1) = 34 others
that could be the other end of a diagnal.
So there must be 34 possible diagnals.
If the full questions as below;
A dessert has both fruit and yogurt inside. altogether,the mass of the dessert is 185g. the ratio of the mass of fruit to the mass of yogurt is 2:3. what is the mass of yogurt?
total dessert 3:3
since the ratio of the mass of fruit is 2:3
the remaining would be
the ratio of the mass of yogurt which is 1:3
then the answer is:
the mass of yogurt would be one 3rd of the total dessert
185g÷3= 61.66g
cool? :)
Answer:
She has 45 Bottles left after drinking them
Step-by-step explanation:
This question needs some more clarification!
From what I read!
We know that Janelle has brought 4 cases of water containing 12 bottles in 1 case.
If she were to drink 3 bottles of water how much bottles will she have left?
First, we would have to do a multiplication problem involving the cases of water and how much bottles in one case.
Equation: 4 Cases x 12 Bottles in Each Case=48 Bottles in Total
Then, Janelle has drunk 3 bottles of water already, so we would need to subtract.
Equation 48 Bottles in Total - 3 Bottles Drunk = 45 Bottles in Total
Therefore, Janelle has 45 Bottles left in her inventory.
Answer:
(4,3)
Step-by-step explanation:
2y = x + 2
x - 3y = -5
Rearrange the second equation to equal y.
x - 3y = -5
x + 5 = 3y
(x+5)/3 = y
Substitute into the first equation.
2y = x +2
2[(x+5)/3] = x + 2
(2x + 10)/3 = x + 2
2x + 10 = 3(x + 2)
2x + 10 = 3x + 6
10 - 6 = 3x - 2x
4 = x
Therefore, the correct ordered pair is (4,3) since x is equal to 4.
