Answer:
First equation is the right answer.
X÷3=0.6
1.8÷3=0.6
0.6=0.6
Hence proved
Answer:
just graph it mate
Step-by-step explanation:
Here are the numbers
4.3 , 5.5 , 6

,

, 4

I'm going to change them into fractions
In the fractions, divide the numerator by the denominator

<em />
⇔6.1666---

⇔3.75

⇔4.375
Now to arrange them from least to the greatest

, 4.3 ,

, 5.5 ,
Answer:
I think it is 90 and 100
Step-by-step explanation:
I used this equation: x is the speed of the slower train
910 = (5x + 10) + 5x
Answer:
63.5
Step-by-step explanation:
The diagonals of a rhombus bisect opposite angles.
The longer diagonal bisects the 42° angle
The larger angle of the rhombus is 180 - 42 = 138
Let x = the length of the longer diagonal
You know two sides and the included angle of a triangle.
Using the law of cosines we get

x^2 = 34^2 + 34^2 - 2(34)(34) cos 138
= 1156 + 1156 - 2312 c0s 138
= 4030.1508...
x = sq rt 4030.1508...
= 63.5
