Step-by-step explanation:
(1,1.5) is the solution but (12,4) is not the solution of given equation.
1.5=1/4×1+5/4(which is true)
4=1/4×12+5/4(which is false)
30in I know that because I just did this .this is EASY!
Answer:
42+30=72
7+5=12
72-12=60
Blank=60
Step-by-step explanation:
Its a distributive propertyyyyyyy.
The equation can be modeled as
X + X + (X+4) = 61
X is used for all because they are all the same number and can be given the same variable
The third is given plus four so we can use a common variable
3x + 4 = 61
3x = 57 (subtracted four)
x = 19 (divided by three)
Solving for third side so x + 4
The third side is 23 inches
