Answer:
A) 5x-7y=42
Step-by-step explanation:
We know that 5 x 7 = 35 then add 7 = 42
We divide 5 and 7 by 5/7
5/ 5/7 = 0.1
7/ 5/7 = 0.2
We find 0.1 = 1/10 and we know that 1/10 of 35 is 3.5
We find 0.2 = 2/10 and we know that 2/10 of 35 is 7 so the answer 7 matches.
We then use 7 for y and keep 5 for x.
First, we can use the points (4,3) and (20,15) to find the slope of the line:
Now we can find the relation function using the point (4,3) and the slope s=3/4
therefore, the equation to describe the relationship between J and M is m=3/4j
Answer:
Astronomers were trying to find the weight of six planets - Mars, Venus, Pluto, Jupiter, Mercury, and Saturn. The number of planets lighter than Mars was equal to the number of planets heavier than Venus. Saturn was heavier than Mars and Mercury were heavier than Pluto. Venus was lighter than Mars. Saturn was not the heaviest planet.

Answer:
75 cm
Step-by-step explanation:
To find the area of a traingle you use the following equation
b*h*.5
We know that the height of the triange is three times the base and that the area is 937.5
This means that
b*3b*.5=937.5
We can combine this and get 1.5b^2=937.5
We can then divide by 1.5 to get b by itself
b^2=625
Then take the square root for our answer and get b=25 (while be also can be -25 it doesn't make sense to have a negative answer in the context of this problem)
So we know that b=25 and that h=3b which means that the height is 75 cm
