Answer:
x=3
y=7
Step-by-step explanation:
solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
5, 3
Step-by-step explanation:
Answer: its AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Answer:
Let the larger number = y and the smaller number = x.
The largest number is 10 less than twice the smaller number. Remember that less than means subtract the 10 from the other amount while twice means multiply by two. Therefore,
y = 2x - 10
The sum of the two numbers is 38. Remember sum means add the two numbers to get their result. Therefore,
x + y = 38
Since y = 2x - 10, we rewrite the lower equation as:
x + (2x - 10) = 38
Solving:
3x - 10 = 38
3x = 48
x = 16
The lesser number is 16 and the greater number is 2(16) - 10 or 22.
Divide it into 1 rectangle and 3 triangles.
Rectangle : 3 x 8 = 24
Triangle 1: 1/2 x 8 x 2 = 8
Triangle 2: 1/2 x 4x3 = 6
Triangle 3: 1/2 x 4x3= 6
Total area = 24 + 8 + 6 + 6 = 44 square units.
