Answer:
1st Side: 27 inches, 2nd Side: 23/2, 3rd Side: 67/2
Step-by-step explanation:
Let's solve your problem step by step:
First side should be: 2x+4
Because 2 times the second side =, and 4 longer than that.
Second side should be: x
This is the base of the equation, since all the numbers depend on "x"
Third side should be: (3x+4)-5
Because x + x+4, and the third side is 5 shorter..
We add all and we get 72.
Solve for x.
x=23/2
Now, we can solve for other sides, by doubling it and adding 4.
This is answer is correct, I tried it. :)
Answer:
23x-4
Step-by-step explanation:
x+22x-4 ( If a <u>term</u> doesn't have a coefficient, it is considered that the coefficient is 1
1x+22x-4 Collect <u>like terms</u> by adding their coefficients (1+22)x-4
Then, add the numbers.
(1+22)x-4
23x-4
Answer:
This is called system of equations.
Step-by-step explanation:
This combines two equations and then lines them up to a system.
30 minutes. the easiest way is to use the opposite of the fraction. divide 25 / 5= 5. now multiply by 6. 5*6= 30.
