Answer:
i) Sally' s grocery bill = c - 
c = 0.95c
Therefore the correct option is B.)
ii) Therefore the expression which represents the expected population
next year is given by :
= p + 
p = 1.075p
Therefore the correct option is B.)
Step-by-step explanation:
Sally has a discount card that reduces the price of her grocery bill in a certain grocery store by 5%.
Let c represent the cost of Sally's groceries.
therefore the expression which represents Sally's grocery bill is given by :
Sally' s grocery bill = c - c = 0.95c
Therefore the correct option is B.)
The population of a city is expected to increase by 7.5% next year If p represents the current population, which expression represents the expected population next year?
Let p = current population of a city.
Therefore the expression which represents the expected population next year is given by :
= p + p = 1.075p
Therefore the correct option is B.)
Answer:
The average weight of a newborn otter is 1.775 kg.
Step-by-step explanation:
We are given the following in the question:
Weight of newborn otter =
Let x lg be the average weight of a newborn otter.
Thus, we are given the relation:
Thus, the average weight of a newborn otter is 1.775 kg.
Answer:
16.5 m
Step-by-step explanation:
Hi there!
Set up a proportion (letting h = the height of the tree):
Multiply both sides by 22 to isolate <em>h</em>:
6/8 * 22 = h
h = 16.5
Therefore, the height of the tree is 16.5 m.
I hope this helps!
Answer:
x/2 + 21 = 36
First we get rid of constants to isolate the variable.
In order to do that we must do the inverse operation.
Inverse operation of addition is subtraction.
-21 -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)
x/2 = 15
inverse property of division is multiplication
x2 x2
X = 30
Answer:
E = 58
F = 32
G = 90
Step-by-step explanation:
3x + 31 + 5x -13 + 90 = 180
3x + 31 + 5x -13 = 90
8x = 90 - 31 + 13
8x = 72
x = 72 / 8
x = 9
E = 3(9) + 31 = 27+31 = 58
F = 5(9)-13 = 45 - 13 = 32
G = 90
