Divide amount a minute by minutes so Factory A= 2.25   Factory B= 2 then multiply those by 2hrs or 120 minutes so 

Factory A = 270 and Factory B = 240
factory A produced more machines

45machines:20mins
20mins=1/3hour
45machines:1/3hour
times 3
135machins=1hour
135machines per hour


B. 30 in 15
15=1/4 hour
30=1/4hour
times 4
120machines per hour

both produce for 2 hours



A. is 135*number of hours, B is 120 times number of hours
135*2+120*2=
270+240=
510

make 510 machines in 2 hours

PLEASE HELP! (WILL GIVE BRAINLIEST FOR RIGHT ANSWER)

Answer:

-41.29*  10^-7

Step-by-step explanation:

You would change the order of the numbers by multiplying -4.44 and 9.3 together and multiply 10^-7 and 10^0. Which would now look like this:

(-4.44* 9.3)* (10^-7* 10^0)

-4.44* 9.3= -41.292 and 10^-7* 10^0= 1* 10^-7. So now the equation would look like this:

-41.292* 10^-7

Then round -41.292 to 2 decimal places which would be -41.29.

-41.29*  10^-7

That's the answer. I hope this helps!

Solve whether the equation have 1 solution no solution or infinity solution
babymother [125]
Steps to solving equations:
Simplify/combine the like terms
Isolate the variable (Get the variable on one side
Solve for the variable

-2y - 7 + 5y = 13 - 2y Simplify/Combine terms
3y -7 = 13 - 2y Isolate variable by adding 2y to both sides
5y - 7 = 13 Add 7 to both sides to get y alone on one side
5y = 20 Divide by 5 on both sides to solve for y
y = 4
You can check your answer by replacing y with 4 in the original equation.
