Answer:
4.5
Step-by-step explanation:
beginning- x+5=3x-4
combine like terms- 9=2x
divide- x= 4.5
25 6/12 = 306/12is the total feet of a string
4 3/12 =51/12 feet got lost
To get a remaining part subtract the lost part from the total string
306/12-48/12=255/12
=21 1/4
Therefore the remaining part of a string is 21 1/4 feet
Answer:
Step-by-step explanation:
<em>2( 2x + 6 ) + 2( x - 3 ) ≤ 66</em>
3x - 3 ≤ 33
x ≤ 10
x ∈ ( - ∞ , 10]
The best way to work this out is to find the total number, minus the remained. In this case, subtract four from 196, and this gives you 192. As you've got to put the pencils into 8 boxes, you have to divide 192 by 8, and this gives you 24.
Therefore, Soni can put 24 pencils can be put into each box, with four pencils remaining.
Hope this helps :)
The third is because the prove is x = fifteen and if a number is next to a letter, it means multiply, sorry I could only do one.
