Answer:
135000
Step-by-step explanation:
Given: A pack of pencils contain a dozen pencils. 450 such packs were put in a carton. There are 25 such cartons.
To find: total number of pencils
Solution:
Total number of pencils in a pack = 1 dozen = 12
Total number of packs = 450
Total number of cartons = 25
Total number of pencils = 12 × 450 × 25 = 135000
So, total number of pencils is 135000.
7.8 * 10^5=since the exponent is positive 5. Then the 7.8 you move the decimal 5 places to the right to be
780000
180-34=146
146-5=141
ratio=1:4
1+4=5
141÷5=28.2
x=28.2
y=112.8

Answer:
x= -7 y=9
Step-by-step explanation:
3x +9y= 60 [1]
-3x +y=30 [2] rewrite this as the following: y=30+3x
With equation [2] you substitute it into equation [1]
so it will now be: 3x+ 9(30 +3x) =60
3x+270 +27x=60
Group the like terms
3x+27x=60-270
30x=-210
x=-7
Use this answer into the same equation
So: 3(-7)+9y=60
-21 +9y=60
9y=60+21
9y=81
y=9
