Answer:
x = 17
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180, that is
6x - 15 + 4x - 7 + 2x - 2 = 180, that is
12x - 24 = 180 ( add 24 to both sides )
12x = 204 ( divide both sides by 12 )
x = 17

Answer:
Step-by-step explanation:
y=3/4x-2
Answer:
y=3/4x-2
Step-by-step explanation:
slope-intercept formual: y = mx + b
m (the slope) = (y2-y1) / (x2-x1) so right here we insert (4-1) / (8-4) = 3/4
b =w here the line touches the y-asix = -2
now insert those numbers in the formual: y = (3/4)x + (-2)
final answer: y=3/4x-2
Write an algebraic expression for the word phrase.
10 times the product of g and h
Answer:
10(g*h)
Step-by-step explanation:
the * is supposed to mean times/multiply
since it is an expression you do not put y= or f(x)= or anything like that
Answer:
10(g*h)
Step-by-step explanation:
"Product" means multiply so you would want to multiply g and h together. You put it in parenthesis because you want to multiply the solution you get from multiplying g and h by 10. To show this, you can simply just put the 10 in front of the parenthesis as that implies multiplication.

x^2-8x=-15 solve by completing the square
Answer:
Step-by-step explanation:
Factorise 4(x+y)(3a-b)+6(x+y)(2b-3a)
Please solve this fast.
Show your calculation.
Answer:
(-3a+4b) (2x+2y)
Step-by-step explanation:
Expand.
4(x+y)(3a-b)+6(x+y)(2b-3a) = 4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay)
4(3ax+3ay-bx-by) + 6(2bx+2by-3ax-3ay) = 12ax+12ay-4bx-4by+12bx+12by-18ax-18ay
Calculate like terms.
12ax+12ay-4bx-4by+12bx+12by-18ax-18ay = -6ax-6ay+8bx+8by
Factorise.
-6ax-6ay+8bx+8by = -3a(2x+2y) + 4b(2x+2y)
Factorise further.
-3a(2x+2y)+4b(2x+2y) = (-3a+4b) (2x+2y)
Jenna has one more logic puzzle to solve!
Write a system of equations to represent this puzzle, using b to represent the value of each book and m to represent the value of each music note. Then solve the system for b and m.
Type the correct answer in each box. Use numerals instead of words.
The value of each book is
.
The value of each music note is
.
Answer:
The value of each book is 7
The value of each music note is 6
Step-by-step explanation:
The first equation includes the sum of 3 books and 2 music notes, so 3b + 2m = 33.
The second equation includes the sum of 1 book and 3 music notes, so b + 3m = 25.
This is the system that represents the puzzle:
3b + 2m = 33
b + 3m = 25
Solve the second equation for b, and then substitute the equivalent expression for b in the first equation. The value of each music note is 6.
Then, Substitute the value of m into one of the original equations to find the value of b . The value of each book is 7.

The sum of a whole number and twice the square of the number is 10. Find the number
Answer:
Hey there !
Solution:
Let the number be x
=> x + 2x² = 10
=> 2x² + x - 10 = 0
Factorising the quadratic equation we get,
=> 2x² + 5x - 4x - 10 = 0
=> x ( 2x + 5 ) -2 ( 2x + 5 ) = 0
=> ( x - 2 ) ( 2x + 5 ) = 0
=> x = 2, -5/2
Since x is a whole number, -5 / 2 wont be applicable.
Hence x = 2.
Hence the number is 2.
Hope my answer helped !
Step-by-step explanation:
What is the midpoint of the line segment with endpoints (-2,-4) and (4,6)?
A. (-6,10)
B. (-3,5)
C. (1,1)
D. (2.2)
E. (3,5)
Answer:
Answer: C. (1,1)
Step-by-step explanation:
Midpoint
Given a segment defined by points (x1,y1) and (x2,y2), the midpoint (xm,ym) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
The endpoints are (-2,-4) and (4,6).
Calculating the midpoint:
[tex]\displaystyle x_m=\frac{-2+4}{2}=\frac{2}{2}=1[/tex]
[tex]\displaystyle y_m=\frac{-4+6}{2}=\frac{2}{2}=1[/tex]
The midpoint is (1,1).
Answer: C. (1,1)

how do you graph x - y < 4
Answer: y > -4 + x
Step-by-step explanation: graph the inequality by finding the boundary line
Answer:
y > -4 + x
***(see graph below)****
Step-by-step explanation:
Graph
x − y < 4
Solve for y
Subtract x from both sides of the inequality.
−y < 4 − x
Multiply each term in −y < 4 − x by −1
Multiply each term in −y < 4 − x by −1. When multiplying or dividing both sides of an
inequality by a negative value, f lip the direction of the inequality sign.
(−y) ⋅ −1 > 4 ⋅ −1 + (−x) ⋅ −1
Multiply (−y) ⋅ −1.
Multiply −1 by −1.
1y > 4 ⋅ −1 + (−x) ⋅ −1
Multiply y by 1.
y > 4 ⋅ −1 + (−x) ⋅ −1
Simplify each term.
Multiply 4 by −1.
y > −4 + (−x) ⋅ −1
Multiply (−x) ⋅ −1.
y > −4 + x
Find the slope and the y-intercept for the boundary line.
Rewrite in s lope-intercept form.
The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
y = mx + b
Reorder −4 and x. y > x − 4
Use the slope-intercept form to find the slope and y-intercept.
Find the values of m and b using the form y = mx + b. m = 1
b = −4
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 1
intercept: (0, −4)
Graph a dashed line, then shade the area above the boundary line since y is greater than −4 + x. y > −4 + x
here is a better picture
On average, light emitted from the Sun takes minutes seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.
Complete question :
On average, light emitted from the Sun takes 8 minutes 19 seconds to reach Earth. Using your approximated speed of light from part (b), as well as the equation distance = rate x time, calculate the approximate distance from the Earth to the Sun in meters. Write your answer in standard form and in scientific notation.
Answer:
1.497 * 10^8km
149700000 km
Step-by-step explanation:
Given that:
Time taken = 8 minutes 19 seconds
Speed of light = 3 * 10^8 m/s
Distance from earth to sun :
Speed * time
(3 * 10^8) * ((8 * 60) + 19)
(3 * 10^8) * 499
= 1497 * 10^8 m or 1497 * 10^5 km = 1.497 * 10^8km
= 149700000000 m
= 149700000 km
= 1497

On Monday. I bought 3 shirts and 7 pairs of pants for a total cost of $17.25. On
Tuesday, I bought 3 shirts and 9 pairs of pants for a total cost of $20.25. Can you
find the price of each item?
Answer:
Shirt: $2.25. and Pants: $1.50
Step-by-step explanation:
Set up equations with shirts as s and pants as p.
3s+7p=17.253s+9p=20.25Subtract them as there are two variables and two equations:
-2p=-3Make positive, 2p=3Divide, p=1.5To find s:
3s+7(1.5)=3s+10.5=17.25, so 3s=6.75 and s=2.253s+9(1.5)=3s+13.5=20.25, so 3s=6.75 and s=2.25Manuela solved the equation below.

5n + 20 -10 + 15n=50
Solve for the variable
Step-by-step explanation:
2n is the answer because you combined the two variables then you do 20n plus 20n minus. 10 equals 50 then subtract 10 from 50 and get forty the divide that by 20 which equals 2

A candle has been burning for 20 min and is now 25 cm tall. In an hour it will be 10 cm tall. Which equation models the height y of the candle in centimeters, x minutes after it was lit?
Answer:
(y - 25) = - 0.25(x - 20)
Step-by-step explanation:
Given that :
Height of candle after burning for 20 minutes = 25 cm
Height after burning for 1 hr (60 minutes) = 10 cm
Height (y) in cm of candle x minutes after being lit:
Using the equation :
(y - y1) = m(x - x1)
m = (change in y / change in x)
Change in height within 60 minutes :
Height at 20 minutes = 25cm
Height after an hour = 10
Change in height per hour = (25 - 10) = 15cm
Hence, m = change in height per minute
15cm / 60 = 0.25cm ( - 0.25) (decrease in height)
y1 = 25 ; x1 = 20
(y - y1) = m(x - x1)
(y - 25) = - 0.25(x - 20)
