Answer:
Step-by-step explanation:
The general equation for a direct variation is y = k*x
So your first step (usually) is to find k
y = k x
when x = 4
then y = 50
- y = k*x
- 50 = k * 4 Divide by 4
- 50 / 4 = k*4/4
- 12.5 = k
Now you can find the value of y when x = 2
- y = k*x
- k = 12.5
- x = 2
- y = ?
y = 12.5 * 2
y = 25
Answer:
80%!
you can put the amount spent on fruit over the total and compare it to a percentage table!
137 because it’s the same as the angle given.
Answer:½((n/2) – ½) – ½ = 10
½(n/2) – ¼ - ½ = 10 (using the distributive property)
¼n – ¼ - ½ = 10 (multiplying to eliminate the parentheses)
¼n – ¾ = 10 (combining like terms)
¼n = 10¾ (adding ¾ to both sides of the equation)
n = 43 (dividing both sides of the equation by ¼)
Step-by-step explanation:
Let’s start by writing Josie’s first step as an expression. Dividing n by 2, then subtracting ½ from
the result would be (n/2) – ½. If we build on this expression with the information in Josie’s
second step, we get ½((n/2) – ½) – ½. Knowing the final result is 10, we can set up the equation
below, and solve for n as follows: hope this helps
