Answer:
d < - 7
Step-by-step explanation:
given
42 < - 6d ( divide both sides by - 6 )
Remembering to reverse the inequality symbol as a consequence
- 7 > d ⇒ d < - 7
Answer:
hello :
the perimeter is : p = 2(w +l)
w :width.... l : the length
54 = 2(w + 23.5)
w+23.5 = 27
w =23.5 ft
Answer:
Step-by-step explanation:
a² - b² = (a+ b)(a - b)
1) (2n-4/2n) ÷ (n^2-4/n)
2) [y^2-36/y^2-49] ÷[ y+6/y-7]
3) [m^2-1/ m^2-m] ÷ [m^2-7m-8/3m
]
Hint : m² - 7m - 8
sum = -7
Product = -8
Factor = (-8), 1
m² - 7m - 8 =m² - 8m + m - 8
= m*(m - 8) + (m-8)
= (m - 8)(m +1)
Answer:
600cm
Step-by-step explanation:
The length of B times the length on A which goes to B = your answer
First, subtract to get the difference.
2.85 – 2.78 = 0.07
Next, divide 2.78 by 100
2.78 ÷ 100 = 0.0278
So, 0.0278 is 1%. Divide 0.07 by 0.0278 to get the answer.
0.07 ÷ 0.0278 ≈ 2.518
2.518 ≈2.5
Therefore, the percentage increase is approximately 2.5% (that's the answer).
Hope this helps!
