Answer:

\angle A=\mathbf{60^{\circ}}\\\angle B=\mathbf{30^{\circ}}\\\angle C=\mathbf{90^{\circ}}

Step-by-step explanation:

Given

Angle C is triple that of angle B.

Angle A is double of angle B

Suppose the angle B is x

So, angle A and C are 2x and 3x

\angle A=2x

\angle B=x

\angle C=3x

Add the angles A, B, and C to get 180^{\circ}

\Rightarrow \angle A+\angle B+\angle C=18^{\circ}\\\Rightarrow 2x+x+3x=180^{\circ}\\\Rightarrow 6x=180^{\circ}\\\Rightarrow x=30^{\circ}\\

\therefore \angle A=\mathbf{60^{\circ}}\\\angle B=\mathbf{30^{\circ}}\\\angle C=\mathbf{90^{\circ}}

Pete can buy daffodil bulbs in packages of 3 for $6.39 or in packages of 2 for $4.40. How much money does he save by buying 30 b
tatyana61 [14]

Answer:

The correct answer is Pete saves $2.10 by buying bulbs in packages of 3 for $6.39 each.

Step-by-step explanation:

Pete can buy daffodil bulbs in packages of 3 for $6.39 or in packages of 2 for $4.40.

He needs to buy 30 bulbs at a better price.

Money spent by buying bulbs in packs of 3 = 10 × 6.39 = $63.90.

Money spent by buying bulbs in packs of 2 = 15 × 4.40 = $66.

Money saved if bought in packs of 3 = 66 - 63.90 = $ 2.10.

Thus Pete should buy 30 daffodil bulbs in packages of 3 and save $2.10.

The following blank indicates a missing operation in the equation.
Natalija [7]
The answer would be 5/2q+9r+6r-20s

Explanation
We have the equation
5(1/2q+3r-4s)
which would equal
5/2q+15r-20s

so with the information
We can subtract 6r from 15r to get 9r
15r-6r=9r
+9r would be the missing piece

So we substitute it in to make the equation true.
5/2q(+9r)+6r-20s
Hope this helps or was correct
