(3x+2)-5y
The Distributive property tells us that we can do this.
Answer:
2(8 x 4) + 2(4 x 10) + 2(8 x 10)
Step-by-step explanation:
the expression represents the surface area, because it is finding the area of the three different sizes of sides, doubling them, then adding them together
Bx,y plus it and then write it out as a simplified form
Answer:
1)
2)
3)
Step-by-step explanation:
1) Length of a ruler = r
Height of Shiela = s
According to the question ,
5 times the length of a ruler increased by 2 .
⇒
Also , 5r + 2 is less than height of Shiela.
Hence , the linear inequality is ⇒
2) Let the cost of each t-shirt be 't' & cost of each short be 's'.
⇒ Cost of dozen of t-shirts = 12t and Cost of half a dozen shorts = 6s
According to the question ,
12t & 6s is not greater than Php 960.
Hence the linear inequality is ⇒
3) Let the number of Php 100-peso tickets be 'p' and let the number of Php 50-peso tickets be 'q'.
According to the question ,
Difference of p & q is not less than 30
Hence the linear inequality is ⇒
