Answer:
a) 6
b) 4.5
c) unsure due to not knowing the whole problem
d) 35
Step-by-step explanation:
Each side of the cage is 2x+4 and there are 4 sides.
This means 4(2x+4) which is equal to 8x+16, the answer is <u>B</u>
Try this solution:
let the unknown two-digits number be 'xy'.
Then it is possible to write any two-digit number as 10x+y, where x - the tens digit and y - the unit digit.
Using the rule described above the phrase 'the tens digit of a number is twice the units digit' may be written as x=2y.
Using the same rule the phrase 'if the digits are reversed, the new number is 36 is less than the original number' may be written as (10x+y)-(10y+x)=36.
These two equations may be resolved as system of two equations:

Check: the original number is 84, the new number is 48; difference is 84-48=36.
answer: 84

Step-by-step explanation:
<em>Hey there!</em>
Well if the length is 18 and 3 inches we need to find the sum of both lengths,
18ft 3in + 18ft 3in = 36ft 6in
Width- 10ft 8in + 10ft 8in = 20ft 16 in -> 21ft 4in
l + w = 57ft 10in

Answer:


Step-by-step explanation:

Move x / 4 to left hand side and change its sign
Similarly, move 2 to right hand side and change it's sign

Take the L.C.M of 3 and 4
L.C.M of 3 and 4 = 12



Subtract 2 from 3

Do cross multiplication


--------------------------------------------------------------------

Distribute 3 through the parentheses

Move x to left hand side and change it's sign
Similarly, move 12 to right hand side and change it's sign

Collect like terms

Subtract 12 from 33

Divide both sides by 7

Calculate
