Answer:
x=18
Step-by-step explanation:
(3x-9)= 45 degrees because the angle you are solving for is half of a right angle (90 divided by 2 = 45)
so you take 45 and add 9 to it. That equals 54. To get the value of x, you divide 54 by 3 and you get 18.
hope this helps!
Answer:
Step-by-step explanation:
The direct proportion equation is y = kx which reads, "y is directly proportional to x". k is the constant of proportionality. In our case, we read this is as, "the number of calories is directly proportional to the number of apples eaten." Our equation would look like c = ka. We first are given that a = 4 and = 380. We will use that to solve for k:
380 = k4 so
k = 95. Now that know the value of k, we will use that along with the number of calories (1045) to find the number of apples, a:
1045 = 95a so
a = 11
This means that it will be 11 apples that contain 1045 calories.
Answer: |10 - (-8)|
The absolute value is 18
Step-by-step explanation:
The distance between two numbers is a subtraction equation.
10 - (-8) Subtracting a negative is like adding a positive
10 + 8 = 18
If you look at it as the first negative sign means -1 multiplied by the next negative number, "Remember that a negative times a negative is a positive!"
Answer:
p = 2a-22
a= p-20
these will help you find the actual value
Step-by-step explanation:
this is not for the actual value
pierre = p
alex = a
p = a+20
p-20 = a
p+22 = 2a
p = 2a-22
Answer:
x = 2
Step-by-step explanation:
log27(x + 7) - log27(x - 1) = ⅔
log27[(x + 7)/(x - 1)] = ⅔
(x + 7)/(x - 1) = 27^⅔
(x + 7)/(x - 1) = 9
x + 7 = 9(x - 1)
x + 7 = 9x - 9
8x = 16
x = 2
