His speed is 6 2/3 mi/hr.
Our equation is 4 = 3/5s; to solve this, we want to divide both sides by 3/5:
4 ÷ 3/5 = (3/5s) ÷ 3/5
4/1 ÷ 3/5 = s
4/1 × 5/3 = s
20/3 = s
6 2/3 = s
Let
Haru's number ---> x
<span>Leon's number ---> (3/8)x
</span>so
ratio of
<span>Leon : Haru = (3/8)x : x </span>
<span>= 3/8 : 1 </span>
<span>= 3 : 8
</span>
the answer is
3 : 8
Petra is 13 and her mother is 32. I used this equation:
if you solve for p, you get 13. 13 times 2 plus 6 equals 32. So her mother is 32.
I will answer if u post the ?s in a coment
First you make -1 and 3/4 have a common denominator. 1 has a fraction of 1/1 so times four it is 4/4. Then you add on both sides in order to isolate x and you get 3/10x = 7/4.
Then you isolate x by multyiplying the reciprocal of 3/10 on both sides, 10/3.
3/10 and 10/3 cancel out and you get an answer of x = 70/4.
You could then simplify it to get 35/6 by finding a greasted common multiple of 12 and 70 which is 2 and dividing both by 2 to get a simpilier answer.
So the answer is x = 35/6
