Answer: the two numbers are 46 and 37
Step-by-step explanation:
Given that:
Sum of two numbers = 83
Sum of two times the first number and three times the second number = 203
From the question :
Let the numbers = a and b respectively
a + b = 83 - - - (1)
2*a + 3*b = 203
2a + 3b = 203 - - - (2)
From (1) :
a + b = 83
a = 83 - b
Substitute a = 83 - b into (2)
2(83 - b) + 3b = 203
166 - 2b + 3b = 203
166 + b = 203
b = 203 - 166
b = 37
From;
a + b = 83
a = 83 - b
a = 83 - 37
a = 46
Answer
36 km
Step-by-step explanation:
Suppose he walked n km on the first day
We create the following equation
n + 3/4 n + (3/4)^2 n = 83.25
n + 0.75n + 0.5625n = 83.25
2.3125n = 83.25
n = 36 km
Answer:
Use the slope formula.
Step-by-step explanation:
1. The slope formula is in the form of y2-y1/x2-x1.
2. Use one set of points as (x1, y1), and the other as (x2, y2).
3. Plug the points into the corresponding values of the slope formula.
4. Solve.
5. Your answer is -2/11.
Factor the quadratic equation (3x-4)(x+3). Then set the factors equal to zero.
3x-4=0, solve to get 4/3
x+3=0 x=-3
