Answer:
b = 2
Step-by-step explanation:
Original Equation:
-12 + 3b - 1 = -5 - b
Add b to both sides
-12 + 4b - 1 = -5
Add 12 to both sides
4b - 1 = 7
Add 1 to both sides
4b = 8
Divide both sides by 4
b = 2
Hope this is what you need :)

Thomas and Sydney have a combined age of 57. Thomas is 13 years older than triple Sydney’s age. How old is Thomas? You must create a system of equations and use substitution to solve.
57-13=44. If Sydney is 11, then Thomas is 46. 11x3=33, and 33+13=46. To check our answer, we will add 46+11. 46+11=57.
3x + 4 = 8x – 11 does anyone know how to do this
Answer:
x = 3
Step-by-step explanation:
Subtract 8x from both sides.
3x+4−8x=8x−11−8x
−5x+4=−11
Subtract 4 from both sides.
−5x+4−4=−11−4
−5x=−15
Divide both sides by -5.
−5x
−5
=
−15
−5

If AD = 8 and AC = 2y - 10 , find the value of y. Then find AC and DC.
Answer:
y=13
Step-by-step explanation:
AD is identical to DC so if half of AC is AD which is 8, AC must be 16
2y - 10 = 16
2y = 26
y = 13

did you type that correctly?
Step-by-step explanation:
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
(x, y) → (x + 5, y – 3)
(x, y) → (x + 5, y + 3)
(x, y) → (x – 3, y + 5)
(x, y) → (x + 3, y + 5)
Answer:
Omg the picture is so funny but the first one describes the translation
(x,y)> (x + 5, y - 3
Step-by-step explanation:
I hope this helped!
Answer:
Its C. (x, y) → (x – 3, y + 5)

x - y = 1
Convert the equation from standard form to slope-intercept form.
Answer:
y=x-1
Step-by-step explanation:
The equation is currently in standard form which is a+b=y and slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To change the form we must move the terms around using Properties of Equality.
First, subtract 1 from both sides
x-y-1=1-1
x-y-1=0
Then, add y to both sides
x-y-1+y=0+y
x-1=y
So that is the equation in slope-intercept form with a slope of 1 and a y-intercept of -1.
Answer:
y=x-1
Step-by-step explanation:
It is y=x-1 because first when we do ANYTHING first. We leave the y on the left side of the equation, since the slope y=mx+b has the y always on the left side. So we subtract x from both sides and we get -y=-x+1. We are NOT DONE yet, so after this, we divide both sides by -1. Why? This is because you cannot have a negative y. Dividing both sides by -1 you finally get y=x-1. If this is trouble some to read, I will also put how to solve the problem down below. :)
Let's solve for y.
x−y=1
Step 1: Add -x to both sides.
x−y=1+−x
−x
−y=−x+1
Step 2: Divide both sides by -1.
−y/ −1 = −x+1 /−1
y=x−1
Answer:
y=x−1
4(3+2x) + 2 = 46 , solve for x I need help I'm a bit confused
Answer:
x=4
Step-by-step explanation:
4(3+2x)+2=46
12+8x+2=46
12+8x=44
8x=32
x=4
Answer:
4
Step-by-step explanation:
You need to start with the 2x inside the parenthesis
If you put 4 in place of x you get 8
8+3=11
then because there isnt any sign between 4 and the parenthesis you multiply
4x11=44
then its easy
44+2=46

Find the difference 10 - ( – 25 )
Answer:
35
Step-by-step explanation:
In such cases where there are two minuses, you join them and turn it into a plus sign. So therefore...
= 10 - ( -25 )
= 10 + 25
= 35

i-solve the fraction 315+79 (show all steps)
Answer:
Step-by-step explanation:
step 1 Address input parameters & values.
Input parameters & values:
The fraction number = 315/79
step 2 Write it as a decimal
315/79 = 3.9873
3.9873 is the decimal representation for 315/79
For Percentage Conversion :
step 1 To represent 3.9873 in percentage, write 3.9873 as a fraction
Fraction = 3.9873/1
step 2 multiply 100 to both numerator & denominator
(3.9873 x 100)/(1 x 100) = 398.73/100
398.73% is the percentage representation for 315/79
Write an equation in slope-intercept form of a line that passes through the point (8,-0) and is perpendicular to the line x - 3y = 15.
y = 3x −24y = 3x −24
y = 3x + 24
y = -3x + 24
y = -3x - 24
Step-by-step explanation:
let eqn be y = mx + b.
3y = x - 15
y = 1/3x - 5
perpendicular means product of grad = -1
hence m = -3.
sun (8, 0):
8 = -3(0) + b
b = 8
therefore, equation if the line is y = -3x + 8

Answer choices:
A. About $1,100
B. About $900
C. About $550
D. About $500
Answer:
b
