It takes about 4 days for the temperature to decrease by 9°F.
An equation is an expression that shows the relationship between two or more variables or numbers.
Let x represent the number of days. Given that the temperature drop decreased by 1 1/2°F each day (- 1 1/2), for it to decrease by 9°F (-9):
-1 1/2 * x = -9
-1.5x = - 9
x = 4 days
It takes about 4 days for the temperature to decrease by 9°F.

Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.
The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.
Kenzie can buy 48 Scrunchies
Step-by-step explanation:
You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

Solve for x. Round to the nearest tenth, if necessary.
Answer:
[tex]\sqrt19[/tex]
Step-by-step explanation:
First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,
9^2 + b^2 = 10^2.
solve, 81 + b^2 = 100
then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].
Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.
4^2 + x^2 = 19.
Solve
16 + x^2 = 19
Subtract 16 from both sides
x^2 = 19
and finally, we take the square root of both sides
x = [tex]\sqrt19[/tex]

An employee earns a 25% commission rate on his sales. One day, he earned $175. What was his amount of sales?
Help Please
Answer:
$700
Step-by-step explanation:
25% = 1/4
the sales would be 100% or 4/4
So if commission rate is 1/4, to find the sales we multiply this by 4:
$175*4= $700
The sales would amount to $700

Doubt clarification - use comment section.
Answer:
Hey mate!
Step-by-step explanation:
Lets take two places _ _
Now first position is filled in 4 ways (can use 2 3 7 9) that implies 4C1
then second position is filled in 3 ways since for first position we used a digit
and the condition is that not to repeat the digits, so it is done in 3C1 ways.
so the answer is 4*3 or (4C1*3C1)=12;

p/ 1 6/7=−4.4 help please!!!!!!!
Answer:
Sorry, I can't type well.
The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The equation is given below.
p / [1 ⁶/₇] = - 4.4
Convert the mixed fraction number into a decimal number. Then we have
1 ⁶/₇ = 1 + ⁶/₇
1 ⁶/₇ = 1 + 0.857
1 ⁶/₇ = 1.857
Then the equation is rewritten as,
p / 1.857 = - 4.4
Simplify the equation, then we have
p = - 4.4 x 1.857
p = - 8.17
The solution of the equation p / [1 ⁶/₇] = - 4.4 will be negative 8.17.
