Answer:
x>350
Step-by-step explanation:
150+x>500
Simplify both sides of the inequality.
x+150>500
Subtract 150 from both sides.
x+150−150>500−150
Answer:
x>350

What was the total amount of water in the tank before it was drained
450 gallons
510 gallons
560 gallons
570 gallons
Total amount of water before it was drained will be 510 gallons.
What is rate?"It is a ratio in which the two terms being compared have different units."
For given question,
We have been given a table for the number of gallons of water left in the tank after being drained for two amounts of time.
First we find the rate at which the water was drained from the tank.
[tex]r=\frac{450-330}{30-10}\\\\ r=\frac{120}{20}\\\\ r=6~gallons~per~minutes[/tex]
Let the amount of water in the tank before it was drained = 'x' gallons
And the initial time = 0
Using the rate formula,
[tex]r=\frac{x-450}{10-0}\\\\ 6=\frac{x-450}{10}\\\\ 60=x-450\\\\x=450+60\\\\x=510~gallons[/tex]
Therefore, total amount of water before it was drained will be 510 gallons.

Teachers should really think about the amount of math homework they assign to their students. All types of learners hate homework. If a student already knows how to work the math, why do they need to practice it over and over? And, students who don’t “get it” in class end up practicing incorrectly over and over, leading to an extreme dislike for school. I think requiring just a few practice problems is more appropriate for students.
How could the author revise the hasty generalizations?
o Suggest that teachers do not know what is best for students.
o Use more emotional language, so the reader feels something strongly.

Answer:
Use x for your variable. Do not simplify
Step-by-step explanation:
Answer: Soooo----- x+(3x-13)
Step-by-step explanation:
So in this case i used x as number. Since we're not solving for anything this is just an expression. so the difference between triple the number so 3x and thirteen so (3x-13) and (a number) added so x+(3x-13) or number added to the difference between triple the number and thirteen

1. You need at least 3 pounds of fruit to make muffins. Blueberries cost
$4 per pound, strawberries cost $3 per pound and you can spend at
most $21 on fruit. (Create a system of inequalities)
Answer:
Step-by-step explanation:
b and s are the pounds of blueberries and strawberries, respectively.
b+s ≥ 3
4b + 3s ≤ 21
The system of inequalities can be represented as x+y≥3 and 3x+4y≤21.
What is inequality?Inequality shows relation between two expression which are not equal to each others.
Given that,
Cost of blueberries = $4 per pound
and cost of strawberries = $3 per pound
Let strawberries are x pound and blueberries are y pound, according to condition there should at least 3 pounds of muffins,
Therefore, x+y≥3
And maximum amount is $21
Therefore, 3x+4y≤21
The inequalities are x+y≥3 and 3x+4y≤21.

Jeremy has hit 5 home runs so
far this season. This represents
20% of his yearly goal. How many
more homeruns does he need to hit
to achieve his goal?
Answer:
20 home runs left to hit.
Step-by-step explanation:
Ok so 100%/20% is 5. Increment 5 home runs until you get to 100%. So, 20% =5, 40% = 10, 80% = 15, and 100% = 20
Answer: 25 home runs
Step-by-step explanation:
20% = 5
40% = 10
80% = 20
80% + 20% = 100%

The aspect ratio, the ratio of the width to the height, of various computer monitors is listed in the table below.
Answer: Monitor C is the different one.
Step-by-step explanation:
The aspect ratio is the relationship between width and height.
So we only need to see the quotients between width and height for each monitor and see which quotient is different.
Monitor A:
Quotient = 1152/864 = 1.333....
Monitor B:
Quotient = 800/600 = 1.333...
Monitor C:
Quotient = 1920/1080 = 1.777...
Monitor D:
Quotient = 1600/1200 = 1.333...
We can see that the one with a different aspect ratio is monitor C.

Answer:
Please check the explanation.
Step-by-step explanation:
Part a)
Given that the two parallel lines are crossed by a transversal line.
Given that
m∠2 = 2x + 54 and m∠6 = 6x - 11
Angle ∠2 and ∠6 are corresponding angles.
Corresponding angles are congruent.
Thus,
m∠2 = m∠6
2x + 54 = 6x - 11
flipe the equation
6x - 11 = 2x + 54
subtract 2x from both sides
6x - 2x - 11 = 2x - 2x + 54
4x - 11 = 54
adding 11 to both sides
4x - 11 + 11 = 54 + 11
4x = 65
dvide both sides by 4
4x/4 = 65/4
x = 16.2500 (round to 4 decimal places)
Part b)
We have already determined
x = 16.2500
Given
m∠2 = 2x + 54
substitute x = 16.2500 in the euation
= 2(16.2500) + 54
= 86.5°
As angle ∠2 and angle ∠1 lie on a straight line. Hence, the sum of their angles must be 180°.
i.e.
m∠1 + m∠2 = 180°
substituting m∠2 = 86.5° in the equation
m∠1 + 86.5° = 180°
subtracting 86.5° from both sides
m∠1 + 86.5° - 86.5° = 180° - 86.5°
m∠1 = 93.5°
Therefore, the measure of angle m∠1 is:
m∠1 = 93.5°Function 1 is defined by the equation y = -2t + 6

Which function has a more negative slope?
Choose 1 answer:
A. Function 1
B. Function 2
C. The functions have the same slope
Answer:
FUNCTION A
Step-by-step explanation:
It said it was right on khan
Function 1 have more negative slope.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Function 1 is defined by the equation y = -2t + 6
Function 2:
Slope = 4/ 4 = 1
Then, the equation would be
y - 0 = 1( t- 4)
y= t - 4
Hence, Function 1 have more negative slope.
