Answer 2
Answer:

Answer

x = 17/5= 3.4

Step-by-step explanation:

5x - 5 = 12

5x= 12+5  (move -5 to other side of equation it becomes +5)

5x= 17 (add 5 to 12)

5x/5 = 17/5   (divide whole equation by 5)

x= 17/5= 3.4

Explain why it does not matter what letter or symbol is used to find an unknown number

Answers

A variable represents an unknown quantity.  No matter which variable you use, it will represent the same unknown quantity, and the same process will be used to solve the problem.  Which variable you use is irrelevant.
It's because the letter represents a number, so it doesn't matter what letter.

Zoey made 5 and 1/2 cups of trail mix for a camping trip. She wants to divide the trial mix into 3/4 cup servings. Ten people are going on the camping trip. Can Zoey make enough 3/4 cup servings so each person on the trip has one serving?

Answers

No she can't.  We could divide 5 1/2 cups by 3/4 cups but there is an easier way.

Let's change 3/4 to .75 and multiply by 10 since we need 10 servings.

.75 x 10 = 7.5  so she would need 7.5 cups or 7 1/2 cups
Since she only has 5  1/2 cups,  she does not have enough.

Solve for x algebraically; (2/3x)+(4/x)=(7/(x+1))

Answers

(2)/(3x) + (4)/(x) = (7)/(x+1) \n \nx\neq 0 \ \ and \ \x+1\neq 0 \n \nx\neq 0 \ \ and \ \x \neq -1

(2 )/(3x)+(4)/(x) = (7)/(x+1) \n\n\ (2+12)/(3x) = (7)/(x+1) \n \n(14)/(3x) = (7)/(x+1)\n \n14(x+1)=3x\cdot 7

14 x+14=21x \n \n14=21x-14x \n \n 7x=14 \ \ /: 7 \n \nx=2
 
(2)/(3x) + (4)/(x) = (7)/(x+1)

(2)/(3x) + (12)/(3x) = (7)/(x+1)

(14)/(3x) = (7)/(x+1)

Cross\ multiply :

14(x+1) = 7 * 3x

14x+14 = 21x

14x-21x =-14

-7x =-14

x = (-14)/(-7)

\boxed{x=2}

Follow the rules to create two number sequences that go to the fifth term each.Rule 1: Multiply by 3 starting from 10. Rule 2: Subtract 7 starting from 58. What is the first term that appears in both sequences?

Answers

Answer:

30

Step-by-step explanation:

10x3=30

30x3=90

90x3=270

270x3=810

58-7=51

51-7=44

44-7=37

37-7=30

also 90,270,and 810 are above 58 so the answers has to be 30

that is just the method to calculate those types of problems
