Answer:
Let width of rectangle be x cm.
3x+x+3x+x=39
8x=39
x=39÷8
=39/8
=4/7/8
3x=39/8×3
=117/8
=14/5/8
Hence, length=14/5/8cm while width=4/7/8cm.

Find the mean: 60, 67, 71, 76, 80
Answer:
The mean is 70.8.
Step-by-step explanation:
Finding the arithmetic mean, or average, can be found by adding up all the numbers divided by the total count of those numbers.
So, we have :: 60, 67, 71, 76, 80.
These numbers added together = 354.
There are 5 numbers listed.
354 / 5 = 70.8.
36 - 8 = 1 + 3
a. true
b. false, 36 = 8 > 1 + 3
c. false, 36. 8 = 1 + 3.6
d. false, 36 = 8 < 1 + 3
Hey there!
36 - 8 = 1 + 3
SOLVING FOR THE LEFT SIDE….
36 - 8
= 28
SOLVING FOR THE RIGHT SIDE….
1 + 3
= 3 + 1
= 4
So, this make your statement [false] because 28 ≠ 4 (Option B.)
The left side is bigger than the right side.
Good luck on your assignment and enjoy your day!

write the equation of the line that satisfies the following conditions.
Answer:
x = 8
y = -6
Step-by-step explanation:
Vertical lines have a undefined slope and horizontal lines have a slope of 0. You'll write the equations for these types of lines like this.
Vertical Lines (x = x-intercept)Horizontal Lines (y = y-intercept)Since we don't have two points, we are going to have to graph the points and draw a line to find the intercepts. The graphs will be shown below. From finding out what the intercepts are, we can substitute the according values into the formula shown above.
x = 8
y = -6

Answer:
80 degrees i believe
Step-by-step explanation:
if supplementary angles =180 then 180-100=80
Answer:
m∠QRS = 80°
Step-by-step explanation:
We know that, sum of supplementary angles is 180°.
Given that ∠ABC and ∠QRS are supplementary, and m∠ABC = 100°.
So, m∠ABC + m∠QRS = 180°
=> 100° + m∠QRS = 180°
=> m∠QRS = 180° - 100°
=> m∠QRS = 80°

Jim washes 2/3 of his car with 1/2 a bottle of soap. What fraction of the soap will he use to clean his entire car?
Answer:
if he uses 1/2 for 2/3, then you can divide 2/3 and 1.2 by 2 to get the remaining soap needed to complete the wash
so to clean the last 1/3 of the car, he`ll use 1/4 of the remaining soap
the entire car needs 3/4 of a bottle of soap
What is |—14|?
A. —14
B. —7
C. 7
D. 14
E. 1 1/4
Answer:
14
Step-by-step explanation:
If the negative was outside of the lines, then the answer would be -14, but that is not the value. It is 14.
Answer:
D
Step-by-step explanation:
-14 is in Absolute Value signs. This means that if a number is in the absolute value signs, It's always positive. So that leaves us with C, D, or E. Absolute value signs also mean they are the same number as if it was negative, so that tells us that the answer is D!

Compare the numbers 6x10-6 to 2x10-8.
Which number has the greater value?
Which number has the lesser value?
How many times greater is the greater number?
Answer:
6×10-6 have greater value than 2×10-8
Step-by-step explanation:
6×10-6
60-6
=54
And
2×10-8
20-8
=12
Thus, 6×10-6 had the greatest value by 42 more than 2×10-8
6×10-6 have greater value than 2×10-8
The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Compare the numbers 6 x 10⁻⁶ and 2 x 10⁻⁸.
Then the numbers can be written as,
⇒ 6 x 10⁻⁶ and 2 x 10⁻⁸
⇒ 600 x 10⁻⁸ and 2 x 10⁻⁸
The number 600 x 10⁻⁸ times greater than the number 2 x 10⁻⁸ will be
⇒ 600 x 10⁻⁸ / 2 x 10⁻⁸
⇒ 300
The greater value is 600 x 10⁻⁸. And the lesser value is 2 x 10⁻⁸. The number 600 x 10⁻⁸ is 300 times greater number 2 x 10⁻⁸.

Which of the following shows the prime factorization of 72 using exponential notation?
Answer:
2^3 .3^2
Step-by-step explanation:
if 2×2×2 = 8
and 3×3=9 then 8×9=72
Answer:
2³ × 3²
Step-by-step explanation:
Repeatedly divide by 2 until finish, then divide by 3
72 ÷ 2 = 36
36 ÷ 2 = 18
18 ÷ 2 = 9 , then
9 ÷ 3 = 3
3 ÷ 3 = 1 ← finish when 1 is reached

Step-by-step explanation:
dywfrfvyetwfkfgffyffusofgsjfdgsdlcgslvgsivsfgfisfgisfdyfdic
Step-by-step explanation:
Hi there!
Given;
f(x) = 5x-1
Now; Simply keep the value of x in the given function.
f(1) = 5*1-11
= -6
Again;
f(3) = 5*3-11
= 15-11
= 4
Therefore, f(1) = -6 and f(3) = 4.

Step-by-step explanation:
The trick to this is looking at the denominator. If the numerators are the same for all fractions you are comparing then things are going to be a bit easier for comparing them. The one that has the biggest denominator is small and the one with the smaller denominator is a bigger fraction.
