Answer:
Subtraction Property of Equality
Step-by-step explanation:
Victor solved this inequality as shown:
Given: 6+3(x+5) = 36
Step 1: 6+3x+15 = 36
Step 2: 3x+21= 36
Step 3: 3x = 15
Step 4: 3x=15
What property justifies the work between step 3, I'm guessing its this question if not message me.
from step 2 to 3 we must use Subtraction Property of Equality since
3x+21 = 36 must subtract 21 both sides
then u get 3x=15
What is the surface area of the rectangular prism shown above?
Answer:
The surface area of the rectangular prism is [tex]160in^2[/tex].
Step-by-step explanation:
The surface area of a 3-dimensional shape is found by adding the area of each side of the shape together. In this case, the areas of each side of the rectangular prism are 20 in, 20 in, 50 in, 50 in, 10 in, and 10 in. Find the surface area by adding each area together and you'll get [tex](50*2)+(20*2)+(10*2)=100+40+20=160in^2[/tex].
Answer:
The answer would be 160 .
Step-by-step explanation:
Good luck honey
A student's course grade is based on one midterm that counts as % of his final grade, one class project that counts as % of his final grade, a set of homework assignments that counts as % of his final grade, and a final exam that counts as % of his final grade. His midterm score is , his project score is , his homework score is , and his final exam score is . What is his overall final score? What letter grade did he earn (A, B, C, D, or F)? Assume that a mean of 90 or above is an A, a mean of at least 80 but less than 90 is a B, and so on.
Answer:
The overall score is 75.6
Letter grade is C
Step-by-step explanation:
The question has missing details (See comment section for complete question).
From the complete question, we have:
Proportion:
[tex]Midterm = 15\%[/tex]
[tex]Project = 25\%[/tex]
[tex]Assignment = 40\%[/tex]
[tex]Exam = 20\%[/tex]
Scores
[tex]Midterm = 66[/tex]
[tex]Project = 90[/tex]
[tex]Assignment = 75[/tex]
[tex]Exam = 66[/tex]
Solving (a): The overall score
To do this, we simply calculate the mean of the given data.
The mean is calculated by multiplying each proportion by the scores..
So, we have:
[tex]Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66[/tex]
[tex]Overall = 9.9 + 22.5 + 30 + 13.2[/tex]
[tex]Overall = 75.6[/tex]
Solving (b): The letter grade
From the question, we have:
[tex]A: Mean \ge 90[/tex]
[tex]B: 80 \le Mean < 90[/tex]
[tex]C: 70 \le Mean < 80[/tex]
The overall score falls in the following category:
[tex]C: 70 \le Mean < 80[/tex]
Because:
[tex]70 \le 75.6 < 80[/tex]
Hence, the letter grade is C

Mathhhhhhh which ones about slope are true
Answer:
i think it is, the second one and the fourth one
Step-by-step explanation:
HELP NEEDED!!!! this is for math and needs to be due at 8. please help me!
Answer:
1/3
Step-by-step explanation:
So remember slope is y/x.
THe y value is 1st y minus 2nd y. In this case 6-4. This gets you 2
The x value is 1st x minus 2nd x. In this case 8-2. This gets you 6
Put the y and x value into your fraction(y/x) and you get 2/6.
This can be simplfyied as 1/3

Step-by-step explanation:
Malik has 3 boxes of baseball cards. Each box has 2 containers with 8 cards in each container.
Malik multiplies 8 x 2 and gets 16.
He then multiplies 3 x 2 and gets 6.
Then he multiplies 16 x 6 and comes to his final answer of 96.
Do you agree with Malik? Why or why not?
Answer:
no
Step-by-step explanation:
I think he did the first step correct, 8×2=16.
He did that because in each box there are 2 containers with 8 cards. so all together there are 16 cards in each box.
But then he should've multiplied 16×3=48 because there are three containers with the 16 cards.

x=70
Step-by-step explanation:
it's 70 because 50 and 20 is proportional to x
Answer:
70
Step-by-step explanation:
The angles <FEB and <AEG are vertical angles. This means they have the same measurement. To find <FEB add the two angles <FED and <DEB together. This equals 70; therefore, x must also be equal to 70 degrees.
