Answer:
yes the solution is 8
Step-by-step explanation:
subtract 9 from both sides
1/2x+9-9=13-9
simplify
1/2x=4
multiply both sides by 2
2 x 1/2=4 x 2
simplify
x=8
Answer:
The area is multiplied by 8.
Step-by-step explanation:
I am pretty sure I multiplied the two diagonals that I randomly selected then multiplied the longest diagonal by eight multiples them together again then divided the bigger area by the smaller area, however, but you might want to double-check the work but the answer is right
Answer:
y = 12
x = 10/3
Step-by-step explanation:
y = -3.6x + 12
From this equation, which is in slope intercept form (y = mx+b), we already know that b represents the y-intercept, so that means the y-intercept is 12.
To find the x-intercept, we need to make y equal 0 to find x. So:
0 = -3.6x + 12
-3.6x = -12
x = 3.33333 --> 3 1/3
x = 10/3
Answer:
it's the last one
Step-by-step explanation:
to find the perimeter, you must add all the sides.
25 plus 25 is 50
multiple x by two for both sides and that will give you the perimeter of 70
Let the number of reptiles on endangered list be 'x'
2x + 16=158
2x=158-16
2x=142
x=71
So there are 71 reptiles on the endangered list
