One plus one equals to one
By solving a linear equation, we will see that Victor is 30 years old.
<h3>
How old is Victor now?</h3>
Let's say that Victor is x years old.
We know that 10 years ago, (x - 10), his age was half of what it will be in 10 years (x + 10).
Then we can write the linear equation:
(x - 10) = (x + 10)/2
Now we can solve that equation for x:
2*(x - 10) = x + 10
2x - 20 = x + 10
2x - x = 10 + 20
x = 30
So we conclude that Victor is 30 years old.

Answer: c. explanation: you would just use the distributive property then you would add like terms do get your answer. heres my work: -(z+1) + 2(z-2) —> -z-1 + 2z-4 —> z-5
Answer:
y = - 2x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (2, - 3) ← 2 ordered pairs from the table
m = 
= 
= - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (3, - 5 ) , then
- 5 = - 6 + c ⇒ c = - 5 + 6 = 1
y = - 2x + 1 ← equation of line
Rachel could get 8 ounce of cheese
Step-by-step explanation:
Step 1:
Let Rachel will pay $0.36 per ounce for cheese.
In option A, for 8 oz of cheese, it is $ 2.88.
Step 2:
Here, for 8 oz of cheese
2.88/8 = 0.36 .
