Answer:

Step-by-step explanation:

5x + 15 = 2x + 3

5x + 15 - 15 = 2x + 3 - 15

5x = 2x + 3 - 15

5x - 2x = 2x - 2x + 3 - 15

5x - 2x = 3 - 15

3x = 3 - 15

3x = -12  ( divide both sides by 3)

x= -4

when 9 is increased by 3x the result is greater than 36. What is the least possible interger value for x?
arsen [322]

Answer:

10

Step-by-step explanation:

"When 9 is increased by 3x"

THis means 9 + 3x

"The result is greater than 36"

We use greater than sign and 36

So we can write:

9 + 3x > 36

SOlving this via equation rules and algebra:

9 + 3x > 36

3x > 36 - 9

3x > 27

x > 27/3

x > 9

This means x is everything greater than 9, which satisfies the equation. So in terms of integers, it can be 10, 11, 12, 13...anything above

We want to find the least possible integer value of x, so it is definitely 10

Martha made 3 birthday cards and she wants to make more. if she makes 5 cards an hour, How many cards will she have after 6 hour
frozen [14]
Well, since she makes 5 cards in ONE hour, we'll just multiply 5 times 6 to find out the total amount of cards made in 6 hours, which is 30. HOWEVER, we mustn't forget to add the amount of cards BEFORE she began making 5 cards per hour, which is 3, so 30 + 3 = 33. She made 33 cards after 6 hours. c:

Quadrilateral TINY is a rhombus. Find the length of IN.<br> Please Help!
kogti [31]
<h3>- - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - </h3>

➷ All sides are equal in length in a rhombus

Therefore:

3x - 1 = x + 5

Subtract x from both sides and add 1 to both sides

2x = 6

Divide both sides by 2:

x = 3

(3) + 5 = 8

IN = 8 (whatever the unit is)

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
