6.70 for paint brushes. for 2 is 6.70×2=$13.40
35-13.40=$21.60 left after 2 paint brushes
4.80×4=$19.20 for 4 tubes of paint
21.60-19.20=$2.40 left after 4 tubes of paint and 2 paint brushes
Answer:
1. 6 cookies 2. 5/12 of the pan is left
Step-by-step explanation:
42/2=21
21(2/3)= 14
14-8=6
6 cookies were left
1/4+1/3= 3/12+4/12=7/12
5/12 of the pan is left
<span>Simplifying
2x + 8y = 10
Solving
2x + 8y = 10
Solving for variable 'x'.
Move all terms containing x to the left,
all other terms to the right.
Add '-8y' to each side of the equation.
2x + 8y + -8y = 10 + -8y
Combine like terms: 8y + -8y = 0
2x + 0 = 10 + -8y
2x = 10 + -8y
Divide each side by '2'.
x = 5 + -4y
Simplifying
x = 5 + -4y</span>
Answer:
Step-by-step explanation:
You know an angle, the side opposite the angle, and the side between them.
Use the Law of Sines.
j3 = arcsin(2.7sin(j1)/4.2) ≅ 27.0°
j2 = 180°-j1-j3 ≅ 108.0°
x = distance from j1 to j2
= 4.2sin(j2)/sin(j1)
≅ 5.7 miles
