answer 3:
They are proportion so just put equal sign and see if hey make sense.
Or you can realize that longer side of tringle for the 2 trangles are 10 and 5 and shorter side of triangle are 5 and 2.5 respectively
No is your answer
Assuming that b ≠ a, the answers will not be the same.
For example, (remembering that b ≠ a) let us assume that b = 10, a = 5
10 - 5 = 5
5 - 10 = -5
5 ≠ -5
So the commutative property of subtraction does not work unless in certain cases, in which a = b.
hope this helps
Answer:
When there are numbers like that next to the radical it means multiply. like this: 2<u>√9</u>. You would first figure out the square root. <u>Square root of 9</u> is 3. 2 times 3 is 6.
After you figure out those problems, you just need to put the number, x, and y in an equation with 2 unknowns.

Answer:
70 -20x = 60 -15x
Step-by-step explanation:
The amount of money left on Josh's card is ...
70 -20x
The amount of money left on Jessica's card is ...
60 -15x
These amounts are the same when ...
70 -20x = 60 -15x
_____
<em>Additional comment</em>
The solution to this equation is ...
10 = 5x ⇒ x = 2 . . same amount after purchase of 2 pizzas
38 rounds to 40.
29 rounds to 30.
