Answers

Answer:

2

Step-by-step explanation:

On the first side it shows 5 ones. If you add 5 by 2 it’s 7. Then on the other side it shows 3 X’s. 3x2 is 6. Plus you add that 1 which makes it 7.

Hope this Helps :)

Each X has a value of 2. In the first section there is one X and 5 1s, this equals 7. In the second section 3 X and a single 1, if they equal 2 then its 3 • 2 = 6 + 1 making them both 7

Someone please helps me do this math

Answers

Answer:

47.06 + d = 150

Step-by-step explanation:

So she's planning to save 150 in total. She already saved 12.64. Her grandmother gave her three times as much as that (12.64 * 3=37.92). so an equation would be 12.64 + d + 37.92 - 3.50 = 150

(where d represents the amt. of money left she needs to earn.) If we add up 12.64 and 37.92, we get 50.56 - 3.50 + d = 150.

50.56 - 3.50 = 47.06, so now the equation is 47.06 + d = 150

Subtract: 150 - 47.06 = 102.94, so d = 102.94

It’s d trust me it has to be through use of elemjnation
