Answer:
<h3>y = ¾x - 3</h3>
Explanation:
−3x + 4y = −12
<em>Add 3x to both sides</em>
−3x + 4y + 3x = −12 + 3x
4y = 3x − 12
<em>Divide both sides by 4</em>
4y / 4 = 3x − 12 / 4
<em>Simplify</em>
GIVEN:
Cost of a taco and a cup of tea = $2.10
Cost of 2 tacos and 3 cup of tea = $5.15
ANSWER:
On solving eq(1), we get
Substitute the value of x in eq(2), we get
- 2(2.10 – y) + 3y = 5.15
- 4.20 – 2y + 3y = 5.15
- y = 5.15 – 4.20
- y = 0.95
So, x = 2.10 – 0.95
Hence, Cost of a taco is $1.15
So, <u>Correct choice</u> - [E] $1.15
36% in decimal from it .36
172.80 + .36 = 173.16
So original price was 173.16
Hey there!
Formula for the area of a circle: 
Formula for the radius of a circle: 
First, let's divide the diameter by 2 in order to find the radius.
16/2 = 8
Next, we'll plug our values into the formula (found above).
A = pi x 8^2
A = pi x 64
A = 64pi^2 or A = 201.1cm^2
