4a and 14a can be combined with 3a! Hope this helped
9.4
8^2 + 5^2 = x^2
89 = x^2
square root of 89 = x
9.4 = x
<h3>Answer: 8x+3y = 16</h3>
============================
Work Shown:
x = number of hours spent running
8x = distance he runs (since he runs at 8 mph)
y = number of hours spent walking
3y = distance he walks (he walks at a speed of 3 mph)
8x+3y = total distance = 16 miles
8x+3y = 16
This equation is in standard form Ax+By = C
--------
Extra Info
Solving for y will get
8x+3y = 16
3y = -8x+16
y = (-8x+16)/3
y = (-8x)/3+16/3
y = (-8/3)x+16/3
This is in slope intercept form y = mx+b
m = -8/3 is the slope
b = 16/3 is the y intercept
Answer:
4
Step-by-step explanation:
27-6=21 1
21-6=15 2
15-6=9 3
9-6=3 4
To reduce down a fraction you can try to find factors that go in both the numerator (top # of fraction) and denominator (bottom #)
So, for 6/9, 3 goes in both of them. When you divide each number by 3 you get:
2/3
