I see a mix of green or hazel.
Answer:
r=4
Step-by-step explanation:
-4 (r+2) =4 (2-2r)
Divide each side by 4
-4/4 (r+2) =4/4 (2-2r)
-(r+2) = (2-2r)
Distribute
-r-2 = 2-2r
Add 2r to each side
-r+2r -2 = 2-2r+2r
r-2 =2
Add 2 to each side
r-2+2 =2+2
r=4
Check
-4 (r+2) =4 (2-2r)
-4 (4+2) =4(2-2*4)
-4(6) =4(2-8)
-24 = 4(-6)
-24 = -24
This checks
Answer:
A) 
B) 
Step-by-step explanation:
On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression 
.
On the right, we have six -1s. So, we can represent the right with the expression 
.
A)
Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:
B)
Now, we can solve the equation for x. Add 1 to both sides:
The left will cancel. Add on the right:
Finally, divide both sides by 5:
The left side will cancel. So, the value of x is:
Answer:
She can spend up to $1237 on furniture. Work is below. Hope this helps!
Step-by-step explanation:
2000-763=1237
If you have different numbers you just have to leave it or multipy it out or simplify it so they are the same and can combine exg
6^2 times 5^3 cannot be combined
but if you have
2^4 times 4^2 that means2^4 times (2^2)^2=2^4 times 2^4=2^8
heere are some exponential laws for if you have the same number
(x^n)(x^m)=x^(n+m)
(x^n)^m=x^(nm)
(x^n)/(x^m)=(x^(m-n))
