The required equation is m = 100-5c.
An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Grace has $100. She is buying charms for her bracelet that cost $5 each.
Let, she buys c charms for her bracelets,
Therefore, the equations become,
m = 100-5c
Where, m is money is she left with.
Hence, the required equation is m = 100-5c.

Mr. Garcia will earn $16 by selling the vase.
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Number of flowers= 48
Number of flowers in each vase = 6
So, number of vase can be made
= 48/6
= 8 vases
Now, if each vase cost $2 then cost 8 vase
= 8 x 2
= $16.

x = −6
x = negative 6 over 5
x = −12
Answer:
Option D is correct.
x = -12
Step-by-step explanation:
Solve:
We can write 49 as:
using exponent rules:
Apply this rules on the given equation:
Simplify:
On comparing both sides we get;
Subtract 2x from both sides we get;
x = -12
Therefore, the value of x is -12
