Answer:
-1/2=x
Step-by-step explanation:
-9 + x = 5x - 7
-x -x
-9=4x-7
+7 +7
-2=4x
-2/4 =4x/4
-1/2=x
Answer:
y=5/1 - 3
Step-by-step explanation:
use rise over run
If the squares are 4 inches then the height of the sides will be 4 inches, so you multiply the area of the base times 4!
Answer:
17
Step-by-step explanation:
Let the larger number be represented by x
Let the smaller number be represented by y
from the question, the next equations can be gotten :
x - y = 9 equation 1
x = 1 + 2y equation 2
Substitute for x in equation 1
1 + 2y - y = 9
1 + y = 9
Collect like terms
y = 9 - 1
y = 8
Substitute for y in equation 1 and solve for x (the larger number)
x - 8 = 9
x = 9 + 8
x = 17
Your answer would be 20.6
