all real numbers less than or equal to 9 and greater than or equal to 7 please hurry
Answer:
[tex]7 \leq x \leq 9[/tex]
Step-by-step explanation:
Let [tex]x[/tex] represent the real numbers.
For the first part, all real numbers less than or equal to 9 in algebra is [tex]x \leq 9[/tex].
For the second part, all real numbers greater than or equal to 7 in algebra is [tex]x \geq 7[/tex].
To combine both inequalities, it would become [tex]7 \leq x \leq 9[/tex].
Hope this helped! If not, please let me know! <3
The real numbers are 7, 8, and 9.
We are given two statements:
All real numbers are less than or equal to 9.All real numbers are greater than or equal to 7.We have to use these two statements, form an inequality for the real number and find the real numbers.
What is inequality?Inequality is a relation that makes a non-equal comparison between two mathematical expressions.
There are five types of inequality:
[tex]Less~~than~ = ~ < \\Greater~~than~=~ > \\Less~~than~~or~~equal~~to~=~\le\\Greater~~than~~or~~equal~~to~=~\ge[/tex]
Let the real number be x.
Now using the two given statements we have,
[tex]x\le9\\x\ge7[/tex]
If we combine these two equations we get,
[tex]7\le x \le 9[/tex]
Thus we can say that the real numbers are 7, 8, and 9.

How many gallons of water will be in the fish tank after 3 minutes? how can you explain your answer
The question is incomplete, the complete question is;
If in 0.5 min the tank gets 0.8 gallons of the water then
how many gallons will be in 1 min ?
how many gallons will be in 3 min?
and how long it takes for 40 gallons?
Answer:
1.6 gallons
4.8 gallons
25 mins
Step-by-step explanation:
This question has to do with proportion.
If it takes 0.5 mins for the tank to get 0.8 gallons
in 1 minute the tank will get 0.8 * 1/0.5 = 1.6 gallons
In 3 minutes the tank will get 3 * 1.6 gallons = 4.8 gallons
if it takes 1 min to get 1.6 gallons
it will take x mins to get 40 gallons
x = 1 * 40/1.6 = 25 mins

1/3 x + y = 4 solve for y
The simplified answer to the equation is [tex]y=-\frac{1}{3}x+4[/tex]
First, subtract [tex]\frac{1}{3}x[/tex] on both sides.
[tex]y=-\frac{1}{3}x+4[/tex]
You have isolated [tex]y[/tex] by itself, and the equation can't be simplified further, so [tex]y=-\frac{1}{3}x+4[/tex] is your answer.
Kayla began a science experiment with 18 grams of an unknown solid. During the experiment, the change in the mass of the solid was – 7 grams. What was the mass of the solid at the end of the experiment? To solve the problem, Edna subtracted 18–( – 7) and came up with an answer of 25 grams. Is Edna correct? Why or why not?
Answer:
No. Enda should have added 18+ (-7) because she needed to add the initial mass and the change in mass.
