-4(3)=-12
-4(6)=-24
-12+(-24)=-36
Answer:
Step-by-step explanation:
Original Ratio = New Ratio All these problems are done the same way. Try to conquer the language.
The original ratio = 24 inches wide / 12 inches tall
Shawna's new ratio = you don't know / 2 inches in height (or tall)
Call what you don't know = x
24/12 = x / 2 Cross multiply
12 * x = 24 * 2 Combine the right
12 * x = 48 Divide by 12
12x/12 = 48/12
x = 4
So the new height is 4 inches.
Answer:
V=14
Step-by-step explanation:
Well its a supplementary angle if you add everything together.
We know theres a 90 degrees angle and a 34 degree angle.
90+34=124
124+4v=180
Since if you add everything up its a straight line
Solve the equation normally
56=4v
14=v
Answer:
5 rolls
Step-by-step explanation:
The perimeter lengths are the same because it's a square. So 12 times 4 is 48. You would need a minimum of 5 rolls because each roll as a length of paper of 10 feet. So 40 feet plus 8 would round to 50. That's why it would be 5 rolls.
