Answer:
The expression for rate per hour is 
.
Explanation:
Given:
A machine paints 340 toy boats in 45 minutes.
To Find:
Expression equals the rate per hour?
Solution:
Finding the expression for rate per minute:
So, rate per minute expression is 
= 
Then, rate per hour expression 
So, rate per hour expression is 
= 453.334 toys per hour.
Hence, the expression for rate per hour is
Answer:
- Given Below.
- [ done below, side changing which changed sign + to - and - to + ]
Step-by-step explanation:
6. x + 21 = 56
→ x = 56 – 21
→ x = 35
7. n – 13 = 8
→ n = 8 + 13
→ n = 21
8. w – 7 =41
→ w = 41 + 7
→ w = 48
9. b + 22 = 89
→ b = 89 – 22
→ b = 67
10. z – 53 = 26
→ z = 26 + 53
→ z = 79
Answer:
x = -7
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (&Roots)
Multiplications
Divisions
Additions
Subtractions

First, add 6 to both sides of the equation:
-5x - 6 = 29
-5x - 6 (+6) = 29 (+6)
-5x = 29 + 6
-5x = 35
Next, divide -5 from both sides of the equation:
(-5x)/-5 = (35)/-5
x = 35/-5
x = -7
-7 is your answer for x.

Answer:
F(4) = 9
Step-by-step explanation:
Notice that for f(4), we need to use the function definition for the partitioned Domain that includes x = 4, and that is the expression :
Therefore:
Angle g would be congruent/equal to itself because of verticals angles theorem. i hope that helped a bit
