Answer:
The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.
Reverse addition and subtraction (by subtracting and adding) outside parentheses. Reverse multiplication and division (by dividing and multiplying) outside parentheses. When multiplying or dividing by a negative number, flip the inequality sign. It does not matter if the number being divided is positive or negative
It's necessary to apply inverse operations on both sides of the equals signs so that you can solve for the variable and balance the equation.
Multi-step inequalities are solved using the same processes that work for solving equations with one exception. When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol. (Much like when you divide by a negative number, the sign of the inequality must flip! Here's why: When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!)
Answer:
Step-by-step explanation:
We know that Mary has two twenty dollar bills, equaling to forty dollars in total.
So lets start on the first few things she buys, the berries, each costing 7.98 dollars and cents, since she only bought two, that means we need to multiply 7.98 by 2
==> 15.96 dollars and cents
Now we can take it out of forty.
$ 40.00
- $ 15.96
-------------------
$24.04
Now we only have 24.04 dollars and cents.
Now for the next few items, the peaches which costs 5.99 each, then since he only bought 3, we multiply 5.99 three times.
==> 17.97 dollars and cents
Now we can take it out of 24.04.
$24.04
- $ 17.97
--------------------
$6.07
Mary has 6 dollars and 7 cents in change.
Desmonds height let’s say x = y + 3
I’m not 100% bc/ I learned this last semester, but I think it’s B. So sorry if I’m wrong. I think this bc/ 0.04 is the interest rate as a percent, 4 is the time, 200 is the amount of money, and the one shows that it is exponential growth.
