Answer:
-3=x
Step-by-step explanation:
3(x+4)-5=2x+4
use distributive property to get:
3x+12-5=2x+4
simplify to get:
3x+7=2x+4
subtract 4 from both sides to get:
3x+3=2x
subtract 3x from both sides to get:
3=-x
multiply both sides by -1 to get your answer:
-3=x

Answer:
[tex]3781/9000[/tex]
Step-by-step explanation:
[tex]0.42\overline{1}=42/100+0.00\overline{1}[/tex].
Recall that [tex]0.\overline{1}=1/9[/tex].
So, we want [tex]42/100+1/9*1/1000[/tex].
This simplifies to [tex]21/50+1/9000[/tex].
We know that [tex]21/50=(21*180)/(50*180)=3780/9000[/tex].
So, our expression is [tex]3780/9000+1/9000=3781/9000[/tex], which can't be simplified more.
So, our answer is [tex]\boxed{3781/9000}[/tex] and we're done!

Use the point-slope formula to write an equation of the line that passes through (6,23) and has a slope of m= 3. Write the answer in slope-intercept form
possible).
y=3x+5
plug your coordinate points into the equation for slope (left corner or the paper)
multiply by the denominator on both sides of the equation
x-6 cancels out and leaves y-23=3(x-6)
multiply x and -6 by 3
add 23 to both sides to isolate y
hope this helps!

At 100 Fahrenheit a certian insect Chirps at a rate of 94 times per minute and at 103 Fahrenheit they trip at 112 times per minute write an equation in slope intercept form that represents the situation
Answer:
y=6x-506
Step-by-step explanation:
Start by finding the slope.
Let your x-axis be temperature and you y-axis be chirps per minute.
This leaves you with your two points to find slope.
The first point would be (100,94) and your second point would be (103,112).
From here we can do the standard slope equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex].
[tex]\frac{112-94}{103-100}[/tex]=[tex]\frac{18}{3}[/tex]
[tex]\frac{18}{3}[/tex] Is your slope for the line which can be simplified to 6.
Next find your y-intercept. This can be found by moving around your
y=mx+b equation.
y-mx=b
Pick a point to substitute into the equation. Ill use (103, 112).
[tex]112-6(103)=b[/tex]
[tex]112-618=b[/tex]
[tex]-506=b[/tex]
[tex]b=-506[/tex]
Knowing slope and the y-intercept we can write the slope intercept equation
y=6x-506
Geometry- remember what we know about verticale angles and solve for X. Then tell me the measure of angle A.
Answer:
m<A = 32°
Step-by-step explanation:
When angles are vertical, it means they are equal to each other:
m<A = m<C
4x - 8 = 2x + 12
4x - 2x = 12 + 8
2x = 20
x = 20/2
x = 10
Solve for A:
4x - 8
4(10) - 8
40 - 8

a sewing project requires material costing $44 plus tassels. If the material and tassels are to be purchased with four $20 dollar bills, how many tassels can be purchased if they cost $2.40 each
Answer:
i think the answer is 15
Step-by-step explanation:
four $20 bills would equal $80
$80- $44 because of materials gives you $36
$36 divided by 2.50 equals 15
i hope this makes sense :)

Triangle ABC is transformed to create triangle MNO and triangle PQR as described below.
MNO represents the translation 2 units left and 2 units down of triangle ABC.
PQR represents the dilation of triangle ABC by a scale factor of 2.
Which of these is correct?
The missing options are located here; https://brainly.com/question/18156103
The option that correctly describes the transformation that took place with triangle ABC is; Option A.
In transformations, translation simply means shifting an object from one position to the other while dilation simply means increasing or decreasing an object by a scale factor.This means that translation preserves the lengths and angles of the object while the lengths and angles change with dilation.Option A; Triangle MNO represents a translated triangle and as such the lengths and angles remain unchanged and so this option is correct.
Option B; Not true because both lengths and sides are preserved as stated above.
Option C; Transformation to PQR denotes dilation by a factor of 2 and as such the lengths and angles change. Thus this option is not true.
Option D; This is not true for the same reason in option C above.

19) If manish saves 40% percent of his monthly income and he spends Rs. 15,000 every month, find his monthly income.
Answer:
Rs 25000
Step-by-step explanation:
Saves 40%
Spends 60%
Spending 60% = 15000
If 60% = 15000
Then divide it by 6 to get 10%
10% = 15000 ÷ 6
10% = 2500
100% = 25000

Is it possible for a number to be a rational number that is not an integer but is a whole number?
Answer:
The rational numbers include all the integers, plus all fractions, or terminating decimals and repeating decimals. Every rational number can be written as a fraction a/b, where a and b are integers. If a number is a whole number, for instance, it must also be an integer and a rational.

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 3 to 2 if there were 4440 total votes how many yes votes were there
Answer:
Y / N = 3 / 2
N + Y = 4440
Since Y = 3/2 N
3/2 N + N = 4440
5/2 N = 4440
N = 8880 / 5 = 1776
Y = 1776 * 3 / 2 = 2664
1776 + 2664 = 4440
2664 / 1776 = 3 / 2
