Finley has 152 yellow, red, and blue marbles in a bag. He has seven more red marbles than yellow marbles, and three times as many blue marbles as yellow marbles. How many yellow marbles does Finley have? Write an equation to represent this problem. Then solve the equation. A. x + x + 7 + 2x = 152; x = 36 B. x + x + 7 + x = 152; x = 48 C. x + x + 7 + 5x = 152; x = 21 D. x + x + 7 + 3x = 152; x = 29

Answers

X=yellow
X+7=red
3x=blue

So x+x+7+3x=152
5x=145
X=29

What is the answer to the equation 5+2(x-1)=12

Answers

$5+2(x-1)=12 \n \n 2 ( x - 1) = 12 - 5 \ / \ subtract \ 5 \ from \ each \ side \n \n 2(x - 1) = 7 \ / \ simplify \n \n x - 1 = (7)/(2) \ / \ divide \ each \ side \ by \ 2 \n \n x = (7)/(2) + 1 \ / \ add \ 1 \ to \ each \ side \n \n x = (9)/(2) \ / \ simplify \n \n$

So, the answer to this problem is x = 9/2 or x = 4.5.

5+2(x-1)= 12
So you need to get rid of parentheses, which is that you have to distribute.
5+2x-2= 12
-5 -5 (Inverse)
2x-2= 7
+2 +2 (Another inverse)
2x= 9
2 2 (Divide)

x= 4.5
----------------------
Check
5+2(4.5-1)=12
5+2(3.5)=12
5+7=12
12=12

2+2 x 4 what is the answer

Answers

Answer: 10

Step-by-step explanation: The order of operations gives us instructions on how to simplify expressions that contain more than one operation.

In this problem, we have both addition and multiplication.

According to order of operations, we must do the multiplication before the addition.

So here, our first step is to multiply 2 × 4 which is 8 and we have 2 + 8 which is 10.

Notice that if we had added first then multiplied, we would have had 2 + 2 which is 4 and 4 × 4 is 16 which is an incorrect answer.

You can see that order of operations is very important.

Answer:the answer is 10
