8x² + 64x = 0
8x(x + 8) = 0
8x = 0 or x + 8 = 0
x = 0 or x = -8
Answer: x = 0 or x = -8
Mary has 5 2/5 yards of string. Written as an improper fraction, 5 2/5 = 27/5 yards of string.
The friend was given 2/3 of the string. The friend received 2/3 * 27/5 = 18/5 yards which is the same as 3 3/5 yards and also 3.6 yards.
After Mary gave the friend the string, Mary had 27/5 - 18/5 = 9/5 yards left.
9/5 yards is the same as 1 4/5 yard and also 1.8 yards.
<h3>Answer: 3x + x = 67</h3><h3>To solve: 4x = 67</h3><h3> /4. /4</h3><h3>x = 16.75</h3><h3></h3>
X+y=70
x-y=26
add te equations
x+y=70
<u>x-y=26 +</u>
2x+0y=96
2x=96
divide by 2 both sides
x=48
sub back
x+y=70
48+y=70
minus 48 both sides
y=22
the 2 numbers aer 48 and 22
