Answer:
$15.75 change
Step-by-step explanation:
Avery starts with $20.
She buys 2 tacos and 1 soda.
$1.25 + $1.25 + $1.75
= $4.25
$20 that she started with - $4.25 that she used.
$20 - $4.25 = $15.75
Answer:
Choice 4 (s - 3 = 12)
Step-by-step explanation:
I think you made a reading error on this question, as it said "for which equation is s = 9 <em>not</em> the solution?" No need to fret though, this can easily be solved by substituting 9 into the variable <em>s</em> of each equation.
1. We know it's not choice 1 (s + 6 = 15), because doing 9 + 6 does equal 15.
2. We know it's not choice 2 (7 + s = 19), because doing 7 + 9 does equal 16.
3. We know it's not choice 3 (13 - s = 4), because doing 13 - 9 does equal 4.
4. Choice 4 (s - 3 = 12) is the correct answer because doing 9 - 3 equals 6, not 12. Thus this equation is incorrect, meaning this is the correct choice.
Choice 4/D is the correct choice.
#9 the sum of two angles is 90 degrees, creating a right angle.
#10 the sum of the two angles is 180 because the form a supplementary angle

<u>Answer</u>
320 cm³
<u>Explanation</u>
Firstly, find the constant of proportionality.
V ∝ 1/p
V = k/p Where V= volume, k = constant and p = pressure of the gas.
1600 = k/4
k = 1600 × 4
= 6,400
The equation will be,
V = 6,400/p
For p =20 Kg/cm²,
V = 6,400/20
= 320 cm³
