Part (A)
(1 cm)/(20 cm) = (6 cm)/(x cm)
1/20 = 6/x
1*x = 20*6
x = 120
120 cm = 120/100 = 1.2 m
<h3>Answer: 1.2 m</h3>
=========================================================
Part (B)
2.2 m = 2.2*100 = 220 cm
(1 cm)/(20 cm) = (x cm)/(220 cm)
1/20 = x/220
1*220 = 20*x
20x = 220
x = 220/20
x = 11
<h3>
Answer: 11 cm</h3>
9514 1404 393
Answer:
Step-by-step explanation:
We can subtract the second equation from 4 times the first:
4(a +b) -(4a +1.5b) = 4(95) -(267.5)
2.5b = 112.5 . . . . . simplify
b = 45 . . . . . . . . . . divide by 2.5
a = 95 -b = 50 . . . find 'a'
The solution is (a, b) = (50, 45).
Answer:
(17-3)/2=7 games
Step-by-step explanation:
So she paid $3 for shoes so we can take away $3 from $17 then we can take that answer and divide it by 2 (because it is $2 per game) and we will get our answer. The equation would be:
(17-3)/2
17-3 is in () because we have to do that first and parenthesis are the p in order of operations (pemdas). Now to solve:
parenthesis first:
(17-3)/2=
14/2=

Gabriel and his sister are in apparent agreement. There is insufficient information to tell whether they are correct or not.
Gabriel's representation is a more compact form of his sister's representation, but they mean the same thing.*
_____
* In some computer applications, one gets a different result from computing 2.5x than from computing x + x + 0.5x. This has to do with the way numbers are represented in the computer and the way they are rounded during multiplication and/or addition. For the purposes of algebra, the expressions mean the same thing.
