(2x-3)+(6x+7)= 180
(2x•6x)+(-3+7)= 180
(12x)+(4) = 180
12x= 180-4
x= 176/12
x= 14.67
Answer:
the unknown number is -13
Step-by-step explanation:
4n -7 = -59
4n = -59 +7
n= -52 /4
n = -13
The scale factor is 1 1/2
Answer:
a=9 ( I think)
Step-by-step explanation:
we know that sqaure roots always equal to the base
(like 3^2 =9 or (root of 5)^2 equals to 5)
so I used "a" as a variable
so we must set it up at a^2= 9^3
of course, you must solve a, by sqaure rooting it

thus, leaving it
a= 9^(3/2)
but take my answer with a grain of salt ^^"
