1) 6r + 7 = 13 + 7r - Subtract 6r from both sides...
7 = 13 + r - Subtract 13 from both sides....
r = -6 Check answer (don't need this part)6(-6) + 7 = 13 + 7(-6)
-36 + 7 = 13 -42
-29 = -29 ( It works )
2) -14 + 6b + 7 - 2b = 1 + 5b - Combine like terms...
-7 + 4b = 1 + 5b - Add 7 to both sides....
4b = 8 + 5b - Subtract 5b from both sides....
-b = 8 - Divide both sides by -1
b = -83) 8x + 4(4x+3) = 4(6x + 4) - 4 - Distributive property
8x + 16x + 12 = 24x + 16 - 4 Combine like terms
24x + 12 = 24x + 12 - Both terms equal each other
0 = 0
Since both terms equal each other, all numbres fit.
All real numbersAt 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
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.

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!

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.

Point R is located at 8,13 where is R after a translation 8 units left and 6 units down
Answer:
On the Y axis
Step-by-step explanation:
Answer:
(0, 7)
Step-by-step explanation:
aight so its set up as (x,y). X on the graph is left and right while y is up and down. "8" means that the X is positive or to the right of the origin. If you go left, essentially you are subtracting. So 8-8=0. Same kind of idea for the Y axis. Up is positive, down is negative. If you're going down 6 from 13 (13-6) then you are at 7. (0,7)

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

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
