Evaluate the following expression when a = -3, b = 2, c = 5, and
d = -4.
2a + 3b
Answer:
2a + 3b = 0
Step-by-step explanation:
So we are given that a = -3, b = 2, c = 5, and d = -4 and we are asked to evaluate the expression 2a + 3b. To evaluate the expression, we would have to plug in -3 for a, 2 for b, 5 for c, and -4 for d:
2a + 3b = 2(-3) + 3(2) = -6 + 6 = 0
So by evaluating the expression we get 0.

Solve: −2c + 6 = 10
Answer:
i believe your answer will be C=-2
Step-by-step explanation:
the equation is -2c + 6 = 10. to solve this youll need to subtract 6 from both sides.
-2c +6 =10
-6 -6
which will now leave you with -2c = 4. then you will divide -2 from both sides. -2/-2 =0 and 4/-2 = -2. so your answer is C=-2

A recycling center was offering cash for different types of recyclables. For each pound of paper recycled they offered $1.41, for each pound of aluminum they offered $1.53 and for each pound of plastic they offered $0.33. Jerry took in 5 pounds of paper, 15 pounds of aluminum and 6 pounds of plastic. How much money did he earn?
Answer:
Total amount earn = $31.98
Step-by-step explanation:
Given:
Cost of paper = $1.41
Cost of aluminium = $1.53
Cost of plastic = $0.33
Amount of paper = 5 pound
Amount of aluminium = 15 pound
Amount of plastic = 6 pound
Find:
Total amount earn
Computation:
Total amount earn = ($1.41)(5) + ($0.33)(6) + ($1.53)(15)
Total amount earn = $7.05 + $1.98 + $22.95
Total amount earn = $31.98

Answer: Choice A) Empty set
This is another way of saying "no solutions"
============================================
Explanation:
Your teacher made a typo. The given inequalities will have boundary lines that both have positive slopes, not negative slopes. So the boundary lines should go uphill as you move from left to right.
See the diagram below to see what the graph should look like.
The upper dashed line is y = (1/2)x+3. The lower dashed line is y = (1/2)x-2
The upper dashed line represents the boundary for y > (1/2)x+3. Region 1 is the set of solution points for y > (1/2)x+3
While the solution set for y < (1/2)x-2 is represented with region 3
There is no overlap between regions 1 and 3 due to the parallel boundary lines.
Put another way: there are no (x,y) points that are in both region 1 and region 3 at the same time.
So that's why there are no solutions to this system of inequalities.
---------------------
Alternative method:
Convert the first inequality into Ax+By > C form
y > (1/2)x+3
2y > x + 6 .... multiply both sides by 2
-x+2y > 6 ... subtract x from both sides
z > 6 .... let z = -x+2y
Convert the second inequality into Ax+By < C form
y < (1/2)x-2
2y < x - 4
-x+2y < -4
z < -4 .... let z = -x+2y
We have some number z that is both z > 6 and z < -4 at the same time, but no such number exists. So this is another way to see we have an inconsistent system with no solutions.
Zach wants to make a profit of more than 300 for painting 4 identical too rooms. The profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is 32.50 for each room. Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than 300
Given :
Zach wants to make a profit of more than 300 for painting 4 identical too rooms.
The cost of supplies is 32.50 for each room.
To Find :
Which inequality and solution represent the dollar amount n, that zack must be paid for each room, if he is to make a profit more than $300.
Solution :
Profit is given by :
Profit = S.P - C.P
Now, it is given that profit > 300 .
Profit = S.P - C.P > 300
[tex]4n - 4\times 32.5 > 300\\\\n - 32.5 > 75\\\\n > \$107.5[/tex]
Hence, this is the required solution.

A student wants to conduct an investigation to find out how much heat energy a 100-gram rock can transfer to water. He has the rock and 300 grams of water in an insulated container. The water is at 20°C. He heats up the rock to 50°C, and places it in the water. What is the most important data for the student to record for this investigation?
I need help with 7th grade science
Answer: The temperature change of the water
The most important data that the student would have to record for the investigation that he is carrying out is temperature.
What is temperature?This is the term that is used to refer to the degree of hotness or the degree of coldness of a given body.
The temperature is the solution here because the factor that the student is set to find out would be how heat is able to transfer to water.
The variable that would be used to represent heat is going to be temperature. This is what would help to determine the amount of heat that has transferred.
This can be checked with the use of a thermometer. The investigation that the student is carrying out here would be what is called a research study.
Heat is one of the variables that is used in the research study. Therefore we can conclude by saying that the most important data that is going to be used in this research would be what is called temperature.

Answer:

Step-by-step explanation:
given the parallel lines cut by. a transversal , determine the value of x . please help due in 30 minutes
Answer:
x = 20
Step-by-step explanation:
The angles are same side interior angles so the add to 180
3x-10 + 5x+30 = 180
Combine like terms
8x +20 =180
Subtract 20 from each side
8x+20 -20 =180-20
8x = 160
Divide by 8
8x/8 =160/8
x = 20
Answer: x = 25
Step-by-step explanation:
When lines are parallel, the same side interior angles are supplementary, meaning they add up to 180 degrees. So to find x, you would add the two expressions and make it equal to 180 degrees.
3x - 10 + 5x + 30 = 180
8x - 20 = 180
8x = 200
x = 25
The answer is x=25

Four less than 5 times a number is the same as 26 more than twice the number.
Answer:
False
Step-by-step explanation:
5x - 4 versus 2x + 26
Imagine x equals 1, then the equations would be:
5(1) - 4 and 2(1) + 26
1 and 28 are not equivalent.
Another example would be x = 6
5(6) - 4 and 2(6) + 26
26 and 38 are not equivalent.
No matter what you replace x with, the expressions are never equal.
