Question in the image below:
Answer:
x = 5/33 or 0.151515151
Step-by-step explanation:
7(-6x-2) = 8(3x-4)
step 1: simplify the equation.
-42x - 14 = 24x - 4
step 2: isolate the variable (using the balance method).
-42x - 14 + 14 = 24x - 4 + 14
-42x = 24x + 10
-42x - 24x = 24x - 24x + 10
-66x = 10
step 3: solve for x.
x = 10 ÷ -66
x = 5/33

Solve the following using substitution
Y = 2X + 4
Y = 0.5x - 2
Answer:
x=−4 and y=−4
Step-by-step explanation:
Let's solve your system by substitution.
y=2x+4;y=0.5x−2
Step: Solve y=2x+4for y:
y=2x+4
Step: Substitute 2x+4for y in y=0.5x−2:
y=0.5x−2
2x+4=0.5x−2
2x+4+−0.5x=0.5x−2+−0.5x(Add -0.5x to both sides)
1.5x+4=−2
1.5x+4+−4=−2+−4(Add -4 to both sides)
1.5x=−6
1.5x
1.5
=
−6
1.5
(Divide both sides by 1.5)
x=−4
Step: Substitute−4 fo rx in y=2x+4:
y=2x+4
y=(2)(−4)+4
y=−4(Simplify both sides of the equation)
Answer:
x=−4 and y=−4

Step-by-step explanation:
how to convert quinary into binary numbers?
If this means x in base 5 is equal to y in base 2
You just have to divide in base 5 by 2
Let's take an example.

27. You are researching the price of a phone. You found an average price of $320.00. One phone cost $295 and another cost $375. Find the price of the third phone.
Answer:
$290
Step-by-step explanation:
Assuming there are only three phones, let x = the third phone's price
We already got the prices of the two phones: $295 and $375.
(295 + 375 + x)/3 = 320
First, multiply both sides by 3 to isolate the expression in the parenthesis.
[(295 + 375 + x)/3 = 320]3
295 + 375 + x = 960
670 + x = 960
Subtract 670 from both sides
670 + x = 960
- 670 - 670
x = 290
Please tell me how to solve this i just started geometry as a freshman and i don’t understand please!!!
Answer:
80 degrees
Step-by-step explanation:
The whole angle EBD is 115 degrees, and angle DBG is 35 degrees, therefore
angle GBE is 115-35=80 degrees
Think about it like this, DBG and GBE need to add up to the angle measure of EBD, in other words 35 + GBE = 115
Answer:
Step-by-step explanation:
<DBE = <DBG + <GBE
<DBE = 115 Given
<DBG = 35 Given
<GBE = ?
You have to know a couple of things before you start.
All the angles meet at B. Notice B is the center letter. the top given is the equation you need to solve the question.115 = <GBE + 35 Subtract 35 from both sides.
115 - 35 = <GBE
80 = <GBE
Please help but actually answer correctly
Find the complement of set B in-universe U.
U is the set of natural numbers less than or equal to 8
B is the set of even factors of 8
Answer:
B' = {1, 3, 5, 6, 7}
Step-by-step explanation:
U = {1, 2, 3, 4, 5, 6, 7, 8}
B = {2, 4, 8}
So the complement ( the set of elements in U but not in B) is:
B' = {1, 3, 5, 6, 7}

what is the sum of (3x^2y+4xy^2-2y^3+3) and (x^2y+2y^3-4)
Answer:
This is the sum ---> 4x^2y + 4xy^2 - 1
Step-by-step explanation:
(3x^2y+4xy^2-2y^3+3) + (x^2y+2y^3-4)
(remove the parenthesis)
= 3x^2y + 4xy^2 - 2y^3 + 3 + x^2y + 2y^3 - 4
(now, group the like terms)
= -2y^3 + 2y^3 + 4xy^2 + 3x^2y + x^2y + 3 - 4
(add the elements you think are alike or similar)
= -2y^3 + 2y^3 + 4xy^2 + 4x^2y + 3 - 4
= 4xy^2 + 4x^2y + 3 - 4
= 4xy^2 + 4x^2y - 1
Answer:
the sum is 4x^2y + 4xy^2 - 1

Someone please help im stuck on this question
Step-by-step explanation:
x = 4.13636363
100x = 413.636363
100x - x = 413.636363 - 4 .13636363
99x = 409.5
x = 409.5 / 99
Answer:
[tex]\frac{91}{22}[/tex]
Step-by-step explanation:
Given: 4.1363636...
Let x=4.1363636...
We can see number 36 ( 2 digit repeating ) so we will multiply it by 100
On multiplying both sides by 100
100x=100*4.1363636...
100x=413.63636 .....
We can write it in term of x
100x=x+409.5
On subtracting both sides by x
100-x=409.5
99x = 409 .5
On dividing both sides by 99
x=[tex]\frac{409.5}{99}[/tex]
x=[tex]\frac{4095}{990}[/tex]
x=[tex]\frac{819}{198}[/tex]
On dividing both number by 9
x=[tex]\frac{91}{22}[/tex]
Therefore, x =[tex]\frac{91}{22}[/tex]

What is an equation of the line that passes through the points (1, 8) and (-1, -2)
Answer:
Step-by-step explanation:
(1,8) (-1,-2)
Slope: (-2-8)/(-1-1) = -10/-2 = 5
y -8 = 5 (x - 1)
y - 8 = 5x - 5
y = 5x +3
what's the answer to this math problem: 5x + 4 = 44
Ques: 5x + 4 = 44
⇒ 5x = 44 - 4
⇒ 5x = 40
⇒ x = 40/5
⇒ x = 8
Answer:X =8
Step-by-step explanation:
5X+4=44
5X=44-4
5X=40
X=40/5
X=8

Answer:
2 is the common ratio
Step-by-step explanation:
Common ratio is obtained by dividing any term from it's previous term.
1 ÷ 1/2 = 2
2 ÷ 1 = 2
Hence 2 is common ratio.
Combine like terms to create an equivalent expression.

AC = 3x + 3, BC = 12, and AB = x + 5. Find AC
As, We're given with,
AB = x + 5, BC = 12, AC = 3x + 3
By segment addition postulate,
⇒AB + BC = AC
⇒x + 5 + 12 = 3x + 3
⇒5 + 12 - 3 = 3x - x
⇒17 - 3 = 2x
⇒14 = 2x
⇒2x = 14
⇒ x = 14/2
⇒ x = 7
Now, finding the measure of AC,
⇒Measure of AC = 3x + 3
= 3(7)+ 3
= 3 × 7 + 3
= 21 + 3
= 24
∴ The measure of AC is 24 ...!
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄Answer:
AC = 24
Step-by-step explanation:
Collinear points all lie on the same line, so point A, B, and C are on one line.
So, Ab + BC = AC
AB + BC = AC
x + 5 + 12 = 3x + 3
x + 17 = 3x + 3
-3 -3
------------------------
x + 14 = 3x
-x -x
------------------------
14 = 2x
/2 /2
------------------------
7 = x
AC = 3x + 3
= 3 (7) + 3
= 21 + 3
= 24
AC = 24
