Answer:

8.5 hours

Step-by-step explanation:

First, you need to subtract 226.50 and 150 which gives you 7.65. After that, you need to divide 76.5 by 9 which will give you 8.5 hours. I hope this helps

‼️‼️solve by substitution {2p-3r=6

Anestetic [448]

Answer:

#7: (p, r) = (0, -2) #8: (z,w) = z, $\frac{8}{3}$ + $\frac{4}{3}$ z), ∈R #9: (c,d) = (3,3) #10: (u,x) ∈∅ #11: (a,b) = (-1, 2) #12:

Step-by-step explanation:

Solve for 2p

2p - 3r = 6

2p = -6 -3r

substitute the given value of 2p into equation 2p - 3r = 6

-6 - 3r - 3r = 6

solve for r

r= -2

substitute value of r in equation

2p = -6 - 3x (-2)

solve for p

p=0

solution is ordered pair (p,r) = (0, -2)

Solve for w

w= $\frac{8}{3}$ + $\frac{4}{3}$ z

substitute the given value of w into equation

6 ( $\frac{8}{3}$ + $\frac{4}{3}$ z) - 8z = 16

solve for z

z ∈ R

The statement is true for any value of z and w that satisfy both equations from the system. Therefore, the solution is in parametric form.

(z,w) = z, $\frac{8}{3}$ + $\frac{4}{3}$ z)

Solve for c

c + d = 6

c = d

substitute the given value of c into equation c + d = 6

d + d = 6

solve for d

d=3

substitute value of d in equation

c=3

solution is ordered pair (c,d) = (3,3)

#10

Solve for u

u= 3-2x

substitute the given value of c into equation

2 (3-2x) +4x = -6

solve for x

x ∈∅

Since the system has no solution for x the answer is

(u,x) ∈∅

#11

Solve for b

b= 5+3a

substitute the value of b into equation

3a + 5 + 3a+ b = -1

solve for a

a= -1

substitute the value of a into equation

b= 5 + 3x (-1)

solve for b

b=2

solution is ordered pair (a, b) = (-1, 2)

nikitadnepr [17]

Answer:

Fiona is correct. Meghan is incorrect.

Step-by-step explanation:

An equation is a mathematical statement consisting of two sides and an equal sign equating those two sides. Each side comprises an <em>expression</em>. An equation is a statement because it claims the two expression equal. This may be true, or false, or true for only certain values of variable appearing in the expression. However, an equation is distinctly different from a simple expression.

You flip a coin and then roll a 6-sided number cube (a die).

expeople1 [14]

Answer:

a) No, it does not matter whether you roll the die or flip the coin first, as these two events are <u>independent</u> of each other, which means they do not affect each other.

b) Yes.
