Deposit mean add 50, then withdraw means taking out 20, you do subtraction: $50-$20=$30
Answer:
-24b - 16c - 36a = -28
Step-by-step explanation:
Given the initial equation of 9a + 6b + 4c = 7 and looking at the second equation of -24b - 16c - 36a, I notice that all of the coefficients of the variables have been multiplied by a factor of -4. Since all of the factors have been multiplied by the same factor, multiplied the answer to the equation by a -4 as well will give us the answer to the problem. Since the original answer is 7, multiplying this answer by a factor of -4: (7)(-4) = -28.
Step-by-step explanation:
Your work is correct, but you need to round. x and y have 2 significant figures, so round your final answer to 2 significant figures:
2.4×10⁶
Answer:
The shorter side: longer side is 385:512
Step-by-step explanation:
We are given that A man has 166 feet of fencing to build the pen
We are supposed to find If one end is a square, find the outside dimensions, if a = 6.
Side of square = x
Perimeter of square =
a=6
Length of rectangular part = x+a = x+6
Breadth of rectangular part = x
Perimeter of rectangular part = 2(l+b)=2(x+6+x)=2(2x+6)
So, ATQ
4x+2(2x+6)=166
4x+4x+12=166
8x=154
x=19.25
Shorter side = 19.25
Longer side = x+6=19.25+6=25.6
So, the shorter side: longer side =
Hence the shorter side: longer side is 385:512
Answer:
Step-by-step explanation:
Perimeter = 48 feet
2*(length + width) = 48
2*(9 + width ) = 48
Divide both sides by 2.
9 + width = 48/2
9+width = 24
Subtract 9 from both sides.
9+width - 9 = 24 - 9
Width = 15 feet
