They're called variables (this sounds like vary because the number that a letter could represent varies) so when i say 1 + x = 3 it is saying that they don't know the value of x yet but of course you can solve that by subtracting 1 from 3 which is 2
the answer will be -5
Step-by-step explanation:
because you have to minus 5 and 10
so the answer will be x =- 5
Answer:
Here is the solution. Hope it helps.
Answer:
Step-by-step explanation:
a) Perimeter of a rectangle = 2 *(L +w)
b) w = L - 2
Answer: B
c) Perimeter = 96 inches
2* (l +w) = 96
2*( L + L - 2 ) = 96 {Combine like terms}
2 * (2L - 2) = 96 {use distributive law}
2*2L - 2*2 = 96
4L - 4 = 96 {Add 4 to both sides}
4L = 96 +4
4L = 100 {divide both sides by 4}
4L/4 = 100/4
L = 25 inches
d) w = L - 2
= 25 - 2
w = 23 inches
