Answer:
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.
And y = Total computers - x
Therefore, The equations can be used to find how many computers the rest of the school has.
Answer:
Option C.
Step-by-step explanation:
In △ONM and △SRQ,
We need to find the value of x that will make △ONM similar to △SRQ by the SAS similarity theorem.
According to SAS similarity theorem, two triangle are similar if two corresponding sides in both triangles are proportional and the included angle in both are congruent.
It is given that . So, both triangles are similar by SAS if
Substitute the given values.
Divide both sides by 8.
Therefore, the correct option is C.
1/10 is equal to 0.1, so you can just times 3 with 0.1. Or you can do it in fraction, just times 3 with 1/10, then you get 3/10 as the answer.
1/10 = 0.1
3 x 0.1 = 0.3
or
3 x 1/10 = 3/10
X=small bag
y=large bag
5x+3y=260
4x+2y=200
(5x+3y=260)*4 =20x+12y=1040
(4x+2y=200)*5 =20x+10y=1000
subtract two equations: 2y=40
divide: y=20
plug y in 5x+3*20=260
simplify x=40
small bag=$40
large bag=$20
