8=108 degrees because 180-92=108
Old scale : 1 in. to 3 ft.
length is 9 in.....9 * 3 = 27 ft (old scale length)
width is 6 in......6 * 3 = 18 ft (old scale width)
new scale : 1 in. to 4 ft
length is 9 in.....9 * 4 = 36 ft (new scale length)
width is 6 in......6 * 4 = 24 ft (new scale width)
Answer:
2x + 12 = 64
x = 26 (mark brain if this helps and is correct)
Step-by-step explanation:
to solve equations with one missing variable we must use the order of operations of equality
step 1: use the subtraction property of equality meaning subtract each side of the equation
ex: 2x + 12 - 12 = 64 - 12 (2x = 52)
step 2: use the division property of equality meaning divide each side of the equation by 2
ex: 2x/2 = 52/2 (x = 26)
step 3: check your answer by putting 26 as x because that is our answer
2(26) + 12 = 64 (multiply 2 * 26)
52 + 12 = 64 (add 52 + 12)
64 = 64 (if both sides of the equation are the same number like 64 = 64 then your answer is true meaning that x is equal to 26)
X=3. So how did it was:
Xsq - 9x - 4 ÷x+2
Xsq-9x-4 ÷x =-2
Xsq-9x ÷ x= - 2-4
Xsq-9x÷x=-6
Xsq-9x=-6x
Xsq=-6x+9x
Xsq=3x
Xsq÷x=3
X=3
