2k + 9 = 7 - 3k
Step 2: Solve for k
[Addition Property of Equality] Add 3k on both sides: 5k + 9 = 7[Subtraction Property of Equality] Subtract 9 on both sides: 5k = -2[Division Property of Equality] Divide 5 on both sides: k = -0.4Don’t answer on this or ur sus

Answer:
21.5m²
Step-by-step explanation:
Area for a square: LxW = A
10x10=100m²
Area for a circle: pi r² = A
pi(5)²=78.5m²
Find the difference:
100m²-78.5m² = 21.5m²

Step-by-step explanation:
Calvin works at a pizza place making pizzas. If he is working alone, he can make an average of 15 3/4 per hour. If he works with his friend Megan, he tends to get distracted, and his rate falls by 1/2 per hour. How many pizzas can Calvin make in a 8- hour shift with Megan?
Explain the operations that will be needed to solve this problem, ans then solve it.
The fraction 1/2 converts to 0.50 in decimal form.
The mixed number 15 & 3/4 is the same as 15.75
If Calvin is distracted, then he makes 15.75-0.50 = 15.25 pizzas per hour on average.
Multiply by 8 to find the total number of pizzas possible.
8*15.25 = 122
Answer: Calvin can make 122 pizzas overall if he is distractedCalvin can make 122 pizzas in an 8-hour shift with Megan.
Since Calvin works at a pizza place making pizzas, and if he is working alone, he can make an average of 15 3/4 per hour, but if he works with his friend Megan, he tends to get distracted, and his rate falls by 1/2 per hour, to determine how many pizzas can Calvin make in a 8-hour shift with Megan, the following calculation must be performed:
Rate of pizzas made x number of hours = Total number of pizzas (15 3/4 - 1/2) x 8 = X (15.75 - 0.5) x 8 = X 15.25 x 8 = X 122 = X
Therefore, Calvin can make 122 pizzas in an 8-hour shift with Megan.

Hello there! I am Grace Rosalia (SilentNature), and I hope my answer will help you! :)
-2x-35=-87
-2x=-87+35
-2x=-52
Divide both sides by -2 to isolate x:
x=26

The solution of the given equation is x = -21.
How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The given equation can be solved as follows,
−2x − 35 = 87
=> -2x = -35 + 87
=> -2x = 42
=> x = -42/2
= -21
Hence, the value of x for the given equation is -21.
