Answer:
x = - 15
Step-by-step explanation:
Given
+ 3 = x - 2
Multiply through by 3 to clear the fraction
4x + 9 = 3x - 6 ( subtract 3x from both sides )
x + 9 = - 6 ( subtract 9 from both sides )
x = - 15
Answer: the unit rate of change is 1500. keith saves 1500 per year
Step-by-step explanation: im not a hundred percent sure about the unit rate one but thats probbably the answer
10/4 = x/20
4x = 200
x = 200/4
x = 50 <== LP = 50
Answer:
16 ft
Step-by-step explanation:
Based on the situation above, it forms into a right triangle. Therefore we can apply the Pythagorean Theorem. We will use the formula below:
c = √( a² + b²)
In the problem above, the ladder acts as the hypotenuse denoted by c. It has a length of 20 ft. While the base denoted by b is 12 ft. Therefore, we need to solve for a. We will derive the formula above.
c² = a² + b²
a² = c² - b²
a = √( c² - b² )
a = √( 20² - 12² )
a = 16
The unit is in ft.
Correct me if I'm wrong. I hope it helps.
You had $51
This is because 36.25 + 14.75 = 51.
This is right because 36.25 - 51 = 14.75
Therefore you started with $51
