Answer:
Step-by-step explanation:
10^3 = 1000
1 km = 1000 meters
5 km = 5 * 1000
5 km = 5000 meters.
No, according to PEMDAS, that expression would be the same as saying 12+(5*3)-4, not the correct expression: (12+5)*3-4.
He used 53 pounds. I got this by using two equations.
a+b=117
and
5.8a+4.1b= 569.8
I took the first equation and subtracted 'b' so the equation looked like a=117-b.
I then plugged in 117-b into the second equation, so it ended up looking like this:
5.8 (117-b)=569.8
5.8 times 117 is 678.6. And 5.8 times negative b is negative 5.8b.
The equation now looks like this:
678.6-5.8b+4.1b=569.8
Add like terms
678.6-1.7b=569.8
Then subtract 678.6 from both sides
-1.7b= -108.8
divide each side by -1.7
you get b= 64.
But because you are looking for how many pounds for a, subtract 64 from 117. You get 53. 53 is the answer.
You would add 7 to both sides to solve the equation! :)
Answer: The slope intercept form is y= -4/5 + 2
Step-by-step explanation:
4x +5y = 10
-4x -4x
5y= 10- 4x divide both sides by 5
y= 2-4/4x write this in slope intercept form
y= -4/5 + 2
