Answer:
Step-by-step explanation:
<u>The perimeters are equal:</u>
<u>Solve for x:</u>
- 12x - 24 = 4x
- 12x - 4x = 24
- 8x = 24
- x = 3
Answers:
120kmh = 72.168mph
50kmh = 31.07mph
Explanation:
This is very simple, just multiply 120kmh by 0.6214 to get 72.168mph. Again multiply 50kmh by 0.6214 to get 31.07mph
So basically the question just wants you to add fractions so we set up the problem like this
1/2+1/5+1/8=weight of herbs=x (x signifies an unknown number)
so
we have to get the bottom numbers the same before we can add them so we
have to find the smallest number that they all can multiply into
so
2=2
5=5
8=2*2*2
so the smallest number that that will go into all three of the numbers is
2*2*2*5 =40
so the bottom number will be 40
so 1/2 is equal to 20/40
1/5=8/40
1/8=5/40
so 20/40+8/40+5/40=33/40
answer is 33/40 grams
so
180°
Step-by-step explanation:
measure of half a circle arc is 180
