Answer/Step-by-step explanation:
The value of x can be solved as follows, take note of the numbers you will need to drag to complete the equations:
4x + 12x = 320 (segment addition postulate)
16x = 320 (combining like terms)
x = 20 (dividing both sides by 16)
We would end up with the value of x, which equals 20.
Numbers that we end up using are: 12, 16, 20, and 320.
Answer:
x = 5 and y = 1 or (5, 1)
Step-by-step explanation:
2x -3y=7
3x-2y=13
Multiply (1st) equation by 3 and (2nd) equation by 2
6x -9y=21
6x-4y=26
----------------subtract
-5y = - 5
y = 1
Substitute y = 1 into 2x -3y=7
2x -3(1)=7
2x - 3 = 7
2x = 10
x = 5
Answer
x = 5 and y = 1 or (5, 1)
A place value chart can help us in finding and comparing the place value of the digits in numbers through millions. The place value of a digit increases by ten times as we move left on the place value chart and decreases by ten times as we move right.
Answer:
The area of the quarter circle is 
Step-by-step explanation:
we know that
The area of a quarter circle is equal to

we have

substitute the value


Step-by-step explanation:
4x² + 11x - 3 = 0
(4x-1)(x+3) = 0
x = 1/4, -3
