<span>7a+(4+5a)=12a+4
The first step to this is to simplify both sides of the equation.
</span><span>You have to combine all of the like terms first...
(7x + 5x) + (4) = 12x + 4
12x + 4 = 12x + 4
Now the second step is to subtract 12x from both sides....
</span>12x + 4 = 12x + 4
-12x -12x
4 = 4
Now you will subtract four from both sides and get....
0=0
Answer:
$541.63
Step-by-step explanation:
To find the balance of Gurindas, we need to break down our values.
Checking Balance = $532.14
Checks = $-46.19 + $-138.32 = $-184.51
Deposit = $200
Service Charge = $-6
Now to find her new balance, we simply add them all together.
New Balance = 532.14 + -184.51 + 200 + -6
New Balance = $541.63
Answer:
X >>>>> Y
–1 >>>> 16
0 >>>>> 8
1 >>>>> 4
2 >>>>> 2
3 >>>>> 1
Step-by-step explanation:
From the question given above,
y = 8 × (½)ˣ
When x = –1, y =?
y = 8 × (½)ˣ
y = 8 × (½)¯¹
y = 8 × 2
y = 16
When x = 1, y =?
y = 8 × (½)ˣ
y = 8 × (½)¹
y = 8 × ½
y = 4
When x = 2, y =?
y = 8 × (½)ˣ
y = 8 × (½)²
y = 8 × ¼
y = 2
When x = 3, y =?
y = 8 × (½)ˣ
y = 8 × (½)³
y = 8 × ⅛
y = 1
SUMMARY:
X >>>>> Y
–1 >>>> 16
0 >>>>> 8
1 >>>>> 4
2 >>>>> 2
3 >>>>> 1
The cost price of the table is $40.
<h3>What is Gain ?</h3>
Gain is the amount gain by selling the product at a higher price than its cost.
Let the cost of the table is $ x
The percentage gain is x% (as given in the question)
Cost price = ?
It is known that
Step 1 : Gain = ( selling Price - Cost Price) * 100 / Cost Price
Selling price = 56
Cost Price = $ x
Therefore substituting the value
x = (56 - x) * 100 / x
x² = 5600 - 100x
x² +100x -5600 = 0
Step 2 : Factorizing
x² + 140x - 40 x -5600 = 0
x( x+14 ) -40( x +14) = 0
( x - 40)(x +14) = 0
x = $40
Therefore the cost price of the table is $40.

Basically, you are asked to find the volume of a cylinder with a diameter of 14 inches and a height of 18 inches. The formula for the volume of a cylinder is
V = pi*(r^2)*h
r is just the half of the diameter. In this case, r = 14/2 = 7. Then,
V = pi*(7^2)*18
V = 2771 cubic inches
