Answer:
A. 7
Step-by-step explanation:
z ÷ (–7) = –1.
multiply each side by -7
z ÷ (–7)*-7 = –1.*-7
z = 7
I need a picture of the cylinders to anwser your question.
Hey!

Steps To Solve:
17 - 2v = -53
~Subtract 17 to both sides
17 - 2v - 17 = -53 - 17
~Simplify
-2v = -70
~Divide 2 to both sides
-2v/-2 = -70/-2
~Simplify
v = 35
------------------------------------------------
Hence, the answer is 
------------------------------------------------
Hope This Helped! Good Luck!
Rational expressions are those that have fractional terms. We state restrictions because it may cause the equation to be undefined in some values of x. The most common restriction for rational expressions is N/0. This means any number divided by zero is undefined.
<h3>What is rational expressions and examples?</h3>
A rational expression is nothing more than a fraction in which the numerator and/or the denominator are polynomials. Here are some examples of rational expressions.
To find the restrictions on a rational function, find the values of the variable that make the denominator equal 0.

Answer: 
Step-by-step explanation:
<h2>We can't solve it but we can simplify</h2>
- 1/4x+1+3/4c-2/3-1/2x, try to move the equation around. Since the operations are in the same level we can do that.
- 1/4x-1/2x+(1-2/3)+(3/4c), 1/4 minus 1/2 can be written as 0.25-0.50 which is -0.25 or -1/4 don't forget to add x (we can do this since there like terms)
- -1/4x+(1-2/3)+(3/4c), now we can convert 1 into a fraction which will become 3/3, so we can rewrite is as 3/3-2/3, which is 1/3
- -1/4x+1/3+3/4c, We can't simplify anymore so this is our final answer.
