3 x / 5 + y / 2 = 13/10 / * 10
0.5 y + 0.04 x = 2.42 / * 100
---------------------------------------
6 x + 5 y = 13 / * ( - 10 )
4 x + 50 y = 242
-------------------------------
- 60 x - 50 y = - 130
+
4 x + 50 y = 242
-----------------------------
- 56 x = 112
x = 112 : ( - 56 ) = - 2
-12 + 5 y = 13
5 y = 25
y = 25 : 5 = 5
Answer:
x = -2, y = 5.
Answer:
You have told us that there is $450 in Josie's bank account, and she does not make any later deposits or withdraws. You have also told us that the gym deducts $35.20 every one month in fees.
Explanation:
The answer is really easy to find. All you have to do is subtract 35.20 from 450. The problem asks for the amount of money that Josie has in her account at the end of the month - the same month that she put $450 into her account.
Solve:
450 - 35.20
= 414.80
Josie has $414.80 in her bank account at the end of the month.

Step-by-step explanation:
domain(6,3,9,5,8)
range(2,5,0,7,1)
Answer:
b = A/h
Step-by-step explanation:
A = bh
Divide both sides by h
A/h = b
b = A/h
We can focus on each part separately, first the numbers:
-3 times (5 squared)
-3 times 25
= -75
This rules out the last two options
Next let’s focus on the x terms:
x^3 times (x^5 squared)
When raising a term that is already raised to a power by another power, you multiply the powers, in this case 5 times 2 = 10
x^3 times x^10
When multiplying numbers with the same base, you add the powers
=x^13
So the answer must be B but we can check the y terms just to make sure
y^2 times (y^4 squared)
y^2 times y^8
=y^10 which matches answer B
