Answer:
14x - 8 = 22 + 20x
x = -5
Step-by-step explanation:
Let "the number" be represented by x
Take each part of the statement and translate into algebraic form
"14 times a number" 14x
"decreased By eight" -8
"is" =
"22 Increased by" 22 +
"20 times The same number" 20x
Put the equation together. Solve for x by isolating.
(
14x - 8 = 22 + 20x
14x - 8 - 20x = 22 + 20x - 20x Subtract 20x from both sides
-6x - 8 = 22
-6x - 8 + 8 = 22 + 8 Add 8 to both sides
-6x = 30
-6x ÷ -6 = 30 ÷ -6 Divide both sides by -6
x = -5
Answer:
11. Eagles to Whales
12. 23:50
13. 27:23
14. 3:5
Step-by-step explanation:
11. Eagles to whales since there are 4 eagles and 2 whales
12. There are a total of 100 senators, so the ratio is 46:100, divide by 2 to get lowest terms
13. #'s are given to you 54:46, just simplify by dividing
14. 21:35, simplify by dividing common terms, which in this case is 7
Answer:
x = 25
Step-by-step explanation:
it's an isosceles triangle so base angles are the same
3x - 30 = 45
Add 30 on both sides
3x = 75
divide both sides by 3
x = 25
