If the side lengths of a Triangle are: 2t, t, 3t, and the perimeter is equal to 60 meters; what is the value of t? a 20 b 12 c 10 d 6
Answer:
x equals 10
Step-by-step explanation:
so so you if the perimeter is 60 and when you measure perimeter you add up all these sides so you would add 2t + t + 3t = 60 then you would divide by 6 and get 10.

2(3y - 6) = 42
Please help thanks :)
Answer:
y = 9
Step-by-step explanation:
Step 1: Write equation
2(3y - 6) = 42
Step 2: Solve for y
Distribute 2: 6y - 12 = 42Add 12 to both sides: 6y = 54Divide both sides by 6: y = 9Angles A and B are complementary. Explain how to find the measure ofAngle BifAngle A has a measure of 36°.
Answer:
54 degrees
Step-by-step explanation:
Complementary angles total 90 degrees.
So, to find B, we subtract 36 from 90.
90-36= 54
Answer:
Sample Response: Complementary angles have a sum of 90°, so the sum of the measures of angles A and B is 90°. Subtract 36° from 90° and angle B has a measure of 54°.
Step-by-step explanation:
The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 101010 denarius per day to support 333 legionaries and 333 archers. It only costs 333 denarius per day to support one legionary and one archer. Use a system of linear equations in two variables.
Complete question :
The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarius per day to support 3 legionaries and 3archers. It only costs 3 denarius per day to support one legionary and one archer. Use a system of linear equations in two variables. Can we solve for a unique cost for each soldier?
Answer:
No unique solution
Step-by-step explanation:
Given that:
Cost of supporting 3 legion aries and 3 archers = 10 denarius daily
Cost of supporting one legionary and one archer = 3 denarius
Let:
Legionaries = l ; archers = a
Equation for the first sentence :
3l + 3a = 10 - - - (1)
Second sentence :
l + a = 3 - - - - - (2)
From (2)
l = 3 - a
Substituting l = 3 - a into (1)
3(3 - a) + 3a = 10
9 - 3a + 3a = 10
9 - 0 = 10
The variable cancels out, Hence, ( there is no unique solution to find the cost of each soldier)
Answer:
No; the system has no solution.
Step-by-step explanation:
We'll use L to represent the cost per day of a legionary, and we'll use A to represent the cost per day of an archer. So we have the following system of equations:
3L+3A=10
L+A=3
If we multiply both sides of the second equation by 3, we get the equation 3L+3A=9
But this indicates that the cost to support 3 legionaries and 3 archers is 9 denarius. The first equation indicates that it costs 10 denarius to support 3 legionaries and 3 archers.
The cost cannot be 9 denarius and 10 denarius at the same time.
Henceforth the answer is:
No; the system has no solution.
Twice the sum of a number and 3.
Thus, the required number is 27.
Question seems to be incomplete. Here, Question could be -
"Twice the sum of a number and 3 is equal to three times the difference of the number and 9 find the number."
What is algebraic expression?
Algebraic expression consists of constant and variable. eg x, y, z etc.
Let the number be 'x'.
Now, applying condition
2(x+3) = 3(x-9)
2x+6 = 3x - 27
x = 21
Thus the required number is 21.

Kimberly tracked the cartoons shown on the channel her kids watch for a week. The probability that the show had animals in it was 0.7 . The probability that the show aired more than 10 times was 0.4. The probability that the show had animals in it and aired more than 10 times was 0.2. Which equation shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 times?
Answer:
p(A or more than 10) = 0.7 + 0.4 - 0.2 = 0.9
Step-by-step explanation:
Given the following probabilifu distribution :
Probability that show had animals in it :p(A) = 0.7
Probability that show aired more than 10 times : p(more than 10) = 0.4
Probability that show had animals and aired more than 10 times: p(A n more than 10) = 0.2
Recall:
P(A or B) = p(A) + p(B) - p(A n B)
Hence,
p(A or more than 10) = p(A) + p(more than 10) - p(A n more than 10)
p(A or more than 10) = 0.7 + 0.4 - 0.2 = 0.9
You read 9.75 pages in your science book and 24.5 pages of a play for English class. It takes you 1.2 minutes to read each page of science and 0.8 of a minute to read each page of the play. How much time do you spend reading?
CLEAR CHECK
Answer:
31.3 minutes were spent reading
Step-by-step explanation:
If it takes 1.2 minutes to read each page for science and you read 9.75 pages of science, then you must multiply these two numbers together
9.75 pages × 1.2 mins = 11.7
If it takes 0.8 of a minute to read each page of the play and you read 24.5 pages of a play, then you also multiplying these two numbers
24.5 pages × 0.8 mins = 19.6
If we must find out the time spent reading, we must add these two numbers together
11.7 + 19.6 = 31.3

f (n) = 5 (n + 2)
Answer:
15,20,25,30
Step-by-step explanation:
f (n) = 5 (n + 2)
Let n=1
f (1) = 5 (1 + 2)
= 5(3) = 15
Let n=2
f (2) = 5 (2 + 2)
= 5(4) = 20
Let n=3
f (3) = 5 (3 + 2)
= 5(5) = 25
Let n=4
f (4) = 5 (4 + 2)
= 5(6)=30
Answer:
15, 20, 25, 30
Step-by-step explanation:
To calculate the value of a term, you plug in the term value into the equation, which, in this case, means replacing the n with the term number.

Answer:
The correct answer is: The y-intercept is 4
Step-by-step explanation:
A. (correct) explanation-The y-intercept is the point where the line crosses the y-axis (vertical line). The y-intercept here is 4 because that is the point where the line crosses the y-axis
B: The x-intercept is 0 (wrong)
B is wrong because the x-intercept is the point where the line crosses the
x-axis (horizontal line)
C: (wrong) A savings account started with $8 in it
C is wrong because the initial amount is usually the y-intercept, but here the y-intercept is 4.
D: (wrong) It took 4 mins to run a mile
D is wrong because there should have been a point at the location (1,4) for this statement to be true, but there is no point there
