She can bake 48 muffins in 90 minutes. Since she can bake 24 in 45 min, 90 min is double that, so double the original amount of cupcakes. 24x2=48
Answer:
∠ 1 = 109° , ∠ 2 = 29° , ∠ 3 = 71°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ 1 + 35° + 36° = 180°
∠ 1 + 71° = 180° ( subtract 71° from both sides )
∠ 1 = 109°
-------------------
∠ RVU and ∠ 1 are adjacent angles on a straight line and sum to 180° , then
∠ RVU + ∠ 1 = 180°
∠ RVU + 109° = 180° ( subtract 109° from both sides )
∠ RVU = 71°
In Δ RVU
∠ 2 + 80° + 71° = 180° ( sum of angles in triangle )
∠ 2 + 151° = 180° ( subtract 151° from both sides )
∠ 2 = 29°
-------------------------
∠ 3 and ∠ RVU are vertically opposite angles and are congruent , then
∠ 3 = 71°
<span>Multiply
the 1st equation by 5 and multiply the 2nd equation by 2. This will
eliminate the x's when you add the two new equations together.

<span>A) −2x+3y=8
B) 5x+4y=10
So we multiply A) by 5 and B) by 2
</span><span>A) −10x+15y=40
B) 10x+8y=20

Adding the equations:
23y = 60
y =

A word or two is/are missing here: "multiplying the purchase price by ."
If the sales tax is 5.5% (just an example), then the tax would be 0.055($25.60), or
$1.41 (rounded up from $1.4108).
Please copy down the entire original problem and see if you can now find the correct answer (for a specific sales tax rate) yourself.
The sale price is $30.
I hope this helps. :)
And have a great day. :)
