Which expression is equivalent to −19y+13 ?
Vikki [24]
The first thing you should do in this case is to write the expression correctly:
 - (1/9) y + (1/3)
 Now, we take out common factor (1/9) obtaining:
 1/9 (-y + 3)
 Let's check:
 1/9 (-y + 3)
 -1/9y + 3/9
 -1/9y + 1/3
 OK
  Answer: 
 An expression equivalent is: 
 1/9 (-y + 3)

Jahyib has 421 dollars. He has 152 dollars more than kelsyann. How much money do Jahyib and Kelsyann have altogether?
zaharov [31]
Both of them together have 690 because you subtract 152 from 421 so...

421-152=269

Then add 269 to 421

421+269=690

Last week, Max earned a total of $162 working at two jobs. He worked 6 hours at his grandfather's store and 10 hours at the loca
VMariaS [17]

The choices are missing but we can find the right equation from the given information

The equation that models this situation is 6 g + 10 m = 162

Step-by-step explanation:

The given is:

  • Max earned a total of $162 working at two jobs
  • He worked 6 hours at his grandfather's store
  • He worked 10 hours at the local  movie theater
  • g represents the hourly rate paid by Max's grandfather, and m represents the hourly rate paid by the movie theater

We need to write an equation models this situation

∵ g represents the hourly rate paid by Max's grandfather

∵ He worked 6 hours at his grandfather's store

∴ He earned from his grandfather = 6 × g = 6 g dollars

∵ m represents the hourly rate paid by the movie theater

∵ He worked 10 hours at the local  movie theater

∴ He earned from the local  movie theater = 10 × m = 10 m dollars

Add 6 g and 10 m to find his total earning

∵ His total earning = 6 g + 10 m

∵ Max earned a total of $162

- Equate his total earning by 162

∴ 6 g + 10 m = 162

The equation that models this situation is 6 g + 10 m = 162

Un carpintero quiere cortar una plancha de triple y de 1m de largo y 60 cm de ancho, en cuadrados lo más grandes posibles. El ca
Ugo [173]

Answer: 20\ cm

Step-by-step explanation:

The first step to solve the exercise is to make the conversion from meters to centimeters.

Since 1\ m=100\ cm, then the dimensions of the wood board in centimeters are:

Lenght=100\ cm\\\\Width=60\ cm

Now, you must find the Greatest Common Factor (GCF). The steps are:

- Descompose 100 and 60 into their prime factors:

100=2*2*5*5=2^2*5^2\\60=2*2*3*5=2^2*3*5

- Multiply the commons with the lowest exponents:

GCF=2^2*5\\\\GCF=4*5\\\\GCF=20

Therefore, the side lenght of each square must be:

s=20\ cm
