8(11-x) = 152
Distributive property:
88-8x = 152
Subtract 88 from each side:
-8x = 64
Divide each side by -8
x = -8
Answer:
228 inches
Step-by-step explanation:
The scale is 12 inches : 5 yards, that means
Real Life 5 yards is 12 inches in drawing.
This is a ratio
We can write:
Now we can create another ratio where drawing length is "x" and real length is 95 yards.
<u>Note:</u> remember to keep yards on numerator and inches on bottom
So, we can write:
We can equate these 2 ratios and cross multiply and solve for x:
Hence 95 yards would be equal to 228 inches in the drawing
Answer:23,87
Step-by-step explanation:
call the 2 numbers x and y
average of 2 numbers being 55 means (x+y)/2 = 55
if the positive difference of the two numbers is 64 then x-y=64
since you have two equations and two variables you can solve for x and y
(x+y)/2 = 55 --> x+y=110
x-y=64 --> x=64+y
x+y=110 and x=64+y --> 64+y+y=110
y=23
x=87
the two numbers are 23 and 87
6+9a-3+6a
=9a+6a+6-3
=15a+3. As a result, A is your final answer. Hope it help!
