EXPLANATION
When x=6 and y=13 x+y = 6 + 13 = 19
x + y = 19
<h3>Given</h3>
a circle with diameter 8 yd
<h3>Find</h3>
the circumference in feet and yards
<h3>Solution</h3>
The circumference of a circle is given by ...
C = πd
where C is the circumference and d is the diameter. For your circle, the circumference is
... C = π(8 yd) = 8π yd ≈ 25.13 yd
There are 3 feet in a yard, so 3 times as many feet.
... C = 24π ft ≈ 75.40 ft
1) x + 3.2= -3.5
subtract 3.2 from both sides
x+ 3.2 - 3.2= -3.5 - 3.2
it cancels out on the left
x= -6.7
2) 8/9x= 32
divide both sides by 8/9
8/9x ÷ 8/9= 32 ÷ 8/9
it cancels out on the left
to divide on the right, multiply fraction by its reciprocal/inverse
x= 32 * 9/8
multiply numerators (top)
x= (32*9)/8
x= 288/8
x= 36
ANSWER: 1) x= -6.7; 2) x= 36
Hope this helps! :)
Answer:
48 hops/minute
Step-by-step explanation:
12 hops/15 seconds * 60 seconds/1 minute = 720 hops/15 minutes
simplify: 48 hops/minute
