I just looked up the question Bc I didn’t know if there was more to it but, Helen bought 15 chips and 8 pretzels. I hope this helps!!
Answer:
(2, 8)
Step-by-step explanation:
Given the system of equation
3x+2y=22 ... *4
-4x+3y=16 .... *3
Using the elimination method
12x + 8y = 88
-12x + 9y = 48
Add
8y + 9y = 88+48
17y = 136
y = 136/17
y = 8
Recall that
3x+2y=22
3x+2(8)=22
3x + 16 = 22
3x = 22-16
3x = 6
x = 6/3
x = 2
Hence the required solution (x, y) is (2, 8)
Answer: Exact Form: a=3√6
Decimal Form: a=1.81712059....
Answer:
20,000
Step-by-step explanation:
20,000 is already rounded to the nearest ten given the tenths place is equal to 0.
![4x^{3}+43x^2+30x](https://tex.z-dn.net/?f=4x%5E%7B3%7D%2B43x%5E2%2B30x)
First in factoring, you must find out what is common in the whole equation
![x(4x^2+43x+30)](https://tex.z-dn.net/?f=x%284x%5E2%2B43x%2B30%29)
Now, make 2 sets of parentheses and "split up" the rest of the equation
Try to experiment which numbers work out
We are not subtracting anything so both parentheses are positive
![x(4x+3)(x+10)](https://tex.z-dn.net/?f=x%284x%2B3%29%28x%2B10%29)
Therefore, the factored version of
![4x^3+43^2+30x](https://tex.z-dn.net/?f=4x%5E3%2B43%5E2%2B30x)
