Answer:
The number is 10/3
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Three times a number increased by ten is equal to twenty
(3n) + 10 = 20
<u>Step 2: Subtract 10 from both sides</u>
3n + 10 - 10 = 20 - 10
3n = 10
<u>Step 3: Divide both sides by 3</u>
3n / 3 = 10 / 3
n = 10/3

Answer:
a) Find the value of the function when x = -2
b) we get f(-2)=65
Step-by-step explanation:
We are given the function f(x)=6(8-x)+5
a) What does the notation f(-2) mean?
The notation f(-2) means that we have to put x = -2 in the given function of f(x) and find the value of the function when x = -2
b) What is the value of f(-2) ?
We need to find the value of f(-2)
Put x = -2
So, we get f(-2)=65
The sum of the inside angles of a 5 sided figure needs to equal 540 degrees.
Add all the angles together to equal 540 and solve for x. Once you have the value for x you can use that to figure out all the angles.
X-8 + 3x-11 + x + 8 + 2x + 7 + x = 540
Simplify by combing like terms:
8x - 4 = 540
Add 4 to both sides:
8x = 544
Divide both sides by 8:
X = 68
Now replace x with 68 in each angle and solve:
U = 68-8 = 60
V = 3(68)-11 = 204-11 = 193
W = 68 + 8 = 76
Y = 68
Z = 2(68) + 7 = 136 + 7 = 143
