If you multiply a. by x it is equivalent to b.
So both are x= z/(w+x)
Answer:
x=5
Step-by-step explanation:
1. Combine like terms to simplify the equation.
Combining like terms means to combine anything that has the same variable, degree, or no variable at all.
-3x and +6x are like terms, for example because they both have an x.
Add them together to get 3x.
2. Rewrite the equation as the simplified version of 3x-8=7.
3. Add 8 to both sides to cancel out 8 on the left side.
3x=15.
4. Divide by 3 to isolate x.
x=5
Answer:
(B)(negative 2) (4)
Step-by-step explanation:
The arrow on the number line ended at negative 8 (-8).
Given the options:
(A) (negative 3) (4) =(-3)(4)=-12
(B)(negative 2) (4) =(-2)(4)=-8
(C) (2)(4)=8
(D)(3)(4)=12
The expected product is -8 since that is where the arrow ended. Therefore, the product that is modeled by the number line is that which gives a result of -8. The correct option is B.
(B)(negative 2) (4) =(-2)(4)=-8
