Simplification/ 15x^6-20x^5+10x^4
Answer:
x=142, y=-360. (142, -360).
Step-by-step explanation:
5x+2y=-10
3x+y=66
----------------
5x+2y=-10
-2(3x+y)=-2*66
-----------------------
5x+2y=-10
-6x-2y=-132
-------------------
-x=-142
x=142
3(142)+y=66
426+y=66
y=66-426
y=-360
Answer:b
Step-by-step explanation: Cause I took the test
Hi there!
This gets pretty easy once you understand how to do these kinds of problems. Let's look at the words in the question.
Adison earned 25$. We can push that to the side.
She loaned her friend 18$, which means she took some money away from her first part of it.
25 - 18 = 7$. Now she has 7$ left. (A calculator would be useful to answer these!)
Now, let's put the 7 to the side and check out the rest of the equation. Looks like Adison's grandmother gave her 50 more dollars, and we know that more means to add.
50 + 7 = 57$.
Now, the final part of the question says she ended up with 86$ because she had money before she earned more. To see how much money she had originally, we can subtract 86 from 57.
86 - 57 = 29$.
We now understand that Adison originally had 29$ before earning anymore money.
Hope this helps!
Biased because she only asked the boys basketball team
