Answer:
152 Chairs
Explanation:
7 rows of 23 chairs: 7 · 23
7 · 23 = 161
Remove 9
161 - 9 = 152
Consecutive numbers are numbers that follow one right after the other. One example is the set {6, 7, 8}. We don't know the three consecutive numbers so let's define...
x = first number
x+1 = second number
x+2 = third number
where x, x+1, and x+2 are consecutive numbers
-----------------------------------------
"The sum of three consecutive numbers is -15" meaning that
x+(x+1)+(x+2) = -15
Let's solve for x
x+(x+1)+(x+2) = -15
x+x+1+x+2 = -15
3x+3 = -15
3x+3-3 = -15-3
3x = -18
3x/3 = -18/3
x = -6
So this means
first number = x = -6
second number = x+1 = -6+1 = -5
third number = x+2 = 6+2 = -4
The list of consecutive values is {-6, -5, -4}
They add up to (-6) + (-5) + (-4) = -11+(-4) = -15
which confirms we have the right values
---------------------------------------------------------
In short, the final answer is -4
W=3/4L
P=2L=2W
70=2L+2(3/4L)
70=2L+6L/4
70=2L+1.5L
70=3.5L
L=70/3.5
L=20 FT. ANS. FOR THE LENGTH.
W=4/4*20=15 ANS. FOR THE WIDTH

Answer:
It should be 396
Step-by-step explanation:
11x6=66
66x6 should get u to 396
Answer:
Step-by-step explanation:
Notice that f(x) = ab would be a constant function, as 'x' does not appear on the right side. If 'a' were increased by 2, the magnitude of f(x) would be increased by a factor of 2. The domain of f(x) would not change; the range would be [a·(b+2)) (a single numeric value).
