Answer:
Step-by-step explanation:
AB and DC are parallel, so ∠B and ∠C are supplementary angles.
∠B = 180°-∠C = 79°
AD and BC are congruent. ∠A = ∠B = 79°
126/7 = 18 so the quotient is 18. There is no need to use distributive property.
Answer:
The inequality is;
2x + 3y ≤ 30
Step-by-step explanation:
Here, we want to select which of the inequalities represent all possible combinations of x roses and y carnations.
From the question, we are told that roses cost $3 and carnations cost $2
So, by buying x roses, total amount spent = $3x
By buying y carnations, total amount spent = $2y
Now, we are told that she does not want to spend more than $30, this means she can spend less than $30 or exactly $30 but cannot spend more than $30
So, by mathematical convention, we say the sum of the roses and carnations bought is less than or equal to $30
Thus we have;
2x + 3y ≤ 30
