Answer:
30x-18 is the area
the perimeter is 10x+6
Step-by-step explanation:
not enough info to solve for x, but we can still have a variable
6(5x-3)
distribute
6(5x)-6(3)

Answers
Answer:
22cm²
Step-by-step explanation:
For the area of triangle,
base = 2 + 2 + 2 = 6cm
height = 4cm
Area = 1/2 x base x height
= 1/2 x 6 x 4
= 12cm²
For area of the rectangle,
length = 5cm
breadth = 2cm
Area = length x breadth
= 5 x 2
= 10cm²
Area of compound shape = 12 + 10 = 22 cm²

A student claims that the expression “9 times the sum of a number and 13" is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?
Answers
Answer:
No, the student is not correct. The correct expression is 9(n+13).
Step-by-step explanation:
"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.
Answer:
Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

the the quotient of the opposite of a number and negative ten
Answers
Answer:
The symbol for absolute value is two vertical lines. Since opposites are the same distance from the origin, they have the same absolute value. For example, the absolute value of "negative 10" is ten, and the absolute value of "positive 10" is also 10.
:))
Answer: x/10
Step-by-step explanation:
the quotient of the opposite of a number and negative ten
Well
The opposite of a number is -x
And negative ten is written as -10
now we need the quotient of -x and -10
If you were asked the quotient of 10 and 2 it would be 10÷2 or 5
So the quotient of -x and -10 would be [tex]\frac{-x}{-10} = \frac{x}{10}[/tex]

Ika nilai rata-rata 20 orang murid adalah 7,5. Kemudian, seorang murid menyusul ulangan dan mendapatkan nilai 8. Berapa nilai rata-rata sekarang?
Answers
Answer:
Average grade now = 7.524
Step-by-step explanation:
Given - If the average score of the 20 students is 7.5. Then a student follows the test and gets a grade of 8.
To find - What is your average grade now?
Proof -
Given that,
Average score of 20 students = 7.5
So,
Total value of students = 20 × 7.5 = 150
Now,
Given that, One person added ang his grade is 8
So,
So Total value of 21 students = 150 + 8 = 158
Now,
Average score of 21 students = [tex]\frac{158}{21}[/tex] = 7.5238
∴ we get
Average grade now = 7.524
PLEASE HELP!!! Find the length of the midsegment to the nearest tenth.
Answers
Answer:
Midsegment is 35.
Step-by-step explanation:
TL; DR:
The smaller triangle (with a base of 6x + 5) has side lengths that are twice as small as the entire triangle (the one with a base of 3x+55). So, 2(6x+5) = 3x + 55. x = 5, so the midsegment is 35.
Look at the photo attached below.
Here is the statement/reason:
1. ED ║ AB (Midsegments are parallel to the base)
Note: Then, CA and CB are transversals
2. Then, m∠CED = m∠EAB (corresponding angles)
3. m∠CDE = m∠DBA (corresponding angles)
4. ΔCED is similar to ΔCAB (angle angle)
5. CA = CE + EA
6. CA = 39 + 39 = 78 (Substitution, algebra)
7. ED/AB = CE/CA (similar triangles)
Note: You can also use CD and CB
8. (6x+5) / (3x+55) = 39 / 78 (substitution)
9. (6x + 5) / (3x + 55) = 1 / 2 (algebra)
10. 12x + 10 = 3x + 55, x = 5 (algebra)
11. ED = 6x + 5 (given)
12. ED = 6*5 + 5 = 35 (substitution, algebra)
An explanation of the algebra:
(6x+5) is twice as small as (3x + 55). So, we can write this equation:
2(6x+5) = 3x + 55
12x + 10 = 3x + 55
Subtract 3x from both sides.
9x + 10 = 55
Subtract 10 from both sides.
9x = 45
x = 5.
Now, put that into ED.
6x + 5 = 6 * 5 + 5 = 35
I hope this helps! Feel free to ask any questions!

x^2 + 3x = 4
x + 3x = √4
4x = 2
x =2/4
x = 1/4
2. 2x^2 - 4x - 3 = 0
2x^2 - 4x = 3
2x^2 - x = 3/4
2x - x = √3/4
x = √3/4
3.x(x-2) = 4
x^2 - 2x = 4
x - 2x = √4
- x = 2

Tina planted a tree that was 6 feet tall and grew 3 feet every year her neighbor planted a tree from a seed but it grew 6 feet every year when will the 2 trees be the same height
Answers
Tina planted a tree. It started at 6 feet and every year it grows another three feet. The expression representing this is 6 + 3x, where x represents years.
Tinas neighbor also planted a tree where each year (which we called x) it grows 6 feet. The expression to represent this is 6x.
If you want to know when they’ll be the same height, then you need to set the expressions equal to each other.
6 + 3x = 6x
To solve, first get the variable to one side
6 = 3x
Divide each side by 3
x = 2
The trees wi be the same height the 2nd year.
0 ft tall at start grows 6ft per year
x years when trees be the same heights
6ft+3ft•x= 0ft+6ft•x
3ft•x-6ft•x=0ft-6ft
-3ft•x= -6ft
X= -6ft/-3ft
X=2 yrs
In 2 years the trees will be at the same height.

What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Fixed amount he earns per week = $15
Additional amount added depending on the number of subscription sold = $3
Let x be the number of subscription sold.
Amount earned in a week = 15 + 3x
If amount earned is $90,
15 + 3x = 90
3x = 75
x = 75 / 3 = 25
Hence the number of subscriptions is 25.

. Jacob and Sadie each got ahead on their skills practices. Jacob completed twelve fewer problems than twice the number Sadie completed. They completed a total of 127 problems. Which system of equations models this situation if Jacob completed j problems & Sadie completed s problems? A) j + s = 127
Answers
Answer:
2s-12=j
S+J=127
Step-by-step explanation:
ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j
. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127
hope this helps!!
