ez points
Step-by-step explanation:
x and y
x=2y+9
x-y=22
*x is the larger number*
plug in x to solve for y
2y+9-y=22
y+9=22
-9 both sides
y=13
plug in y and solve for X
x=2 (13)+9
x=26+9
x=35
1 rod or long is a column of 10 unit cubes.
10 longs placed side by side, form a flat (with dimensions 10×10)
10 flats, placed on top of each other form a large cube, with dimensions 10×10×10 = 1000 cubes.
-------------------------------------------------------------------------------------------------
each small cube (unit cube) represents the number 1.
thus each long represents 10
each flat represents 100
and each large cube represents 1,000
The number 13,450 can be written as
1*10,000+3*1000+4*100+5*10 using the expanded form.
This means that there are 13 large cubes, 4 flats and 5 longs needed to model the number.
Answer: 13 large cubes, 4 flats, 5 longs
Answer:
Step-by-step explanation:
hello
as an apple costs a pence and a banana b pence
3 apples + 5 bananas cost 3*a + 5*b
hope this helps
-3y+10=-5y+8 add 5y to both sides
2y+10=8 subtract 10 from both sides
2y=-2 divide both sides by 2
y=-1
