4v^2 +v -3 = 0 (4v-3)(v+1)=0 4v=3 so v = 3/4 OR v=-1
You would have to subtract 5 on both sides to isolate the variable.
-3x + 5 < 23
- 5 - 5
------------------
-3x < 18
divide both sides by -3.
-3x < 18
x > -6
Hope this helped!
Answer:
The total price that he has to pay is $21.8.
Step-by-step explanation:
Mr. O'Donnell goes to the store to buy a shirt. The shirt is $20, but he also has to pay a 9% tax.
First you convert the sales tax percentage to its decimal form: in this case 9% becomes 0.09.
To calculate the cost of the tax, the following multiplication must be performed:
cost of product or service* sales tax (in decimal form) = total sales tax
In this case:
$20*0.09= $1.8
Finally, you must add the value of the total sales tax to the cost of the product or service to obtain the total cost. In this case:
$20 + $1.8= $21.8
So, <u><em>the total price that he has to pay is $21.8.</em></u>
Answer:
(2^2)(z^7)
Explanation:
The quotient rule states that if two powers have the same base and are on opposite places of a fraction (one is on the numerator, the other on the denominator), you subtract the exponents.
First looking at the powers with the bases of 2, 2^8 is the numerator and 2^6 is the denominator. When we subtract 8-6 we get 2, so 2^8/2^6 would simplify to 2^2.
Then, we look at the powers with the base of z. z^10 is the numerator and z^3 is the denominator. When we subtract 10-3 we get 7, so z^10/z^3 would simplify to z^7.
I hope this helps! Please comment if you have any questions:)
we call n - the number
2×n + 15 = 3×n + 8
2×n - 3×n = 8 - 15
-n = -7 │ ×(-1)
n=7
