Answer:
Step-by-step explanation:
What you wrote below the top line and the bottom line are not the same thing.
I think you really want the second line, but one can't be sure.
(1*2 + 5)/2 div (9/8)
7/2 // 9/8
7/2 * 8*9
7*8/18 = 56/18 = 28/9
If you really do want the top line (the latex) it is different.
1 2/5 div (8/9) Is there such a thing as tfrac? I didn't know this but there is.
(1*5 + 2)5 // (8/9)
7/5 // 8/9 Invert the bottom fraction and multiply
7/5 * 9 / 8
63 / 40
1 23/40
Answer:
(1,4) or 1 < x < 4
Step-by-step explanation:
3 = less than 2x + 1 and 2x + 1 is less than 9
we can split the two parts of the equation
3< 2x + 1 and 2x + 1 < 9
for 3< 2x + 1 x has to be greater than 1
for 2x+ 1 < 9 x has to be less than 4 so the answer is (1,4) or 1 < x < 4
Answer:
Step-by-step explanation:
We want to find equation of a circle with center (-4,6) and radius 9cm.
The equation of a circle with center (h,k) and radius 
units is given by;
We substitute the radius and the center to obtain;
The required equation is:
