1. 1m=100 cm
1m^2= 10,000 cm^2
2. if 3 pencils are 1.65, then 1 pencil is 1.65/3=$ 0.55
7 pencils will cost 7* $0.55= $3.85
3.1 ha is 10,000 m^2, and 1 soccer filed is roughly 100m *110 m
so it makes sense that 1 ha is roughly 2 tennis courts
4.odd numbers between 20 and 30 are
21,23,25,27,29
lets add the,m
21+23+25+27+29=125
5 a rhombus has 2 lines of symmetry
Answer:
Step-by-step explanation:
Let's first write the expression:
Now we can simplify. Be sure to remember to distribute the "-" to all the numbers in the parentheses. You can picture it like multiply "-1" to all the numbers in the parentheses to make it easier.
Now we combine like terms.
Write the polynomials by decreasing exponents
So,
The ratio of Ryan to Charlie is 1:5
Ryan=x
Charlie=5x
5x+x=1608
6x=1608
Divide both sides by 6
1608/6=268
x=268
Ryan has 268 stamps.
Charlie has 5(268) 1340 stamps.
1340+268=1608
1340-268=1072.
Charlie has 1072 more stickers than Ryan.
Hope I helped!
The second one is correct. 66/300 = x/100
The awnser is 16 because 16/2 is 8 and 8 is your awnser because, 16 cut in half is 8.
