Stewart School has 178 computers Grade 3 has 58 computers and flgrade 4 has 57 computers What equations can be used to find how many computers the rest of the s class=

Respuesta :

Answer: [tex]x=58+57=115[/tex]

[tex]y=178-115=63[/tex]


Step-by-step explanation:

Let x be the number of computers Grade 3 and grade 4 has and y be the numbers of computers the rest of school has.

Then, x= Grade 3 computers +Grade 4 computers.

[tex]\Rightarrow\ x=58+57=115[/tex]

And y = Total computers - x

[tex]\Rightarrow\ y=178-115=63[/tex]

Therefore, The  equations can be used to find how many computers the rest of the school has.

[tex]x=58+57=115[/tex]

[tex]y=178-115=63[/tex]



You can use subtraction to get how many computers the rest of the school has.

The equations that can be used to find the number of computers in the rest of the school is

[tex]178 - 58 = x,\: \: x= 120\\120 - 57 = y, \: \: y = 63[/tex]

How to find the number of computers in the rest of the school?

Since it is known as there are total 178 computers,

and that Grade 3 has got 58 computers,

Thus, remaining number of computers if we don't count grade 3 is

[tex]178 - 58 = 120 \text{\:\:(let we denote it by x)}\\x = 120[/tex]

Grade 4 has 57 out of those 120 computers,

Thus,

Remaining computers in the school (say y computers are left) is

[tex]y = 120 - 57 \\y = 63[/tex]

Thus,

The equations that can be used to find the number of computers in the rest of the school is

[tex]178 - 58 = x,\: \: x= 120\\120 - 57 = y, \: \: y = 63[/tex]
