The first step would be applying the distributive property.
2x - 1(5 - 3x) = 4x + 2
Distributive property.
2x - 5 + 3x = 4x + 2 is what the equation looks like after successfully applying the distributive property.
-9. A coefficient is a number in front of a variable. Ex -23b. -23 would be the coefficient because that’s a number. And always remember to carry along the negative sign as well
For this case, the first thing we must do is define variables.
We have then:
x: Maggie's age
y: Age of Maggie's brother
We write the system of equations that models the problem.
We have then:
We solve the system of equations.
For this, we use substitution:
From here, we clear the value of x:
Answer:
Maggie is 9 years old
Need help with what ...?.???????
Answer:
86.19°
Step-by-step explanation:
Let x represent the missing value.
The given trigonometric equation becomes:
We take the inverse tangent of both sides to obtain:
This implies that;
We use at least a scientific calculator to evaluate this and obtain:
To the nearest hundredth, the missing value is
