What is the value of s in the equation 4(2s - 1) = 75 + 12?
Answer:
s=91/8
Step-by-step explanation:
4(2s-1)=75+128s-4=878s=91s=91/8Answer: s=91/8
Step-by-step explanation:
To find the value of s, you want ot use your algebraic properties to isolate s.
4(2s - 1) = 75 + 12 [distribute by FOIL]
8s-4=75+12 [add]
8s-4=87 [add both sides by 4]
8s=91 [divide both sides by 8]
s=91/8

Answer:
x = 11/4
Step-by-step explanation:
[tex]\frac{x+8}{4} = \frac{6x+5}{8}[/tex]
Step 1: Cross-multiply.
[tex](x+8)*(8)=(6x+5)*(4)[/tex]
[tex]8x+64=24x+20[/tex]
Step 2: Subtract 24x from both sides.
[tex]8x+64-24x=24x+20-4x[/tex]
[tex]-16x+64=20[/tex]
Step 3: Subtract 64 from both sides.
[tex]-16x+64-64=20-64[/tex]
[tex]-16x=-44[/tex]
Step 4: Divide both sides by -16.
[tex]\frac{-16x}{-16} = \frac{-44}{-16}[/tex]
[tex]x = \frac{11}{4}[/tex]
The area of max'ss room ,not incleding his closet is 235.675 square feet the area of his closet is 10.45 square feet what area of his room ,including the closet

Answer: just add givento number 1 and your all done bro
Step-by-step explanation:
Explain how you can write an equation for the given situation in standard form. One number is 5 more than a second number. The product of the two numbers is 891.
A) Let x be the smaller number, and then x+5 is the larger number. This means that x(x+5)=891, which can be rewritten as x^2+5x-891=0
B) Let x be the smaller number, and then x+5 is the larger number. This means that x+(x+5)=891, which can be rewritten as 2x-886=0
C) Let x be the smaller number, and then x+5 is the larger number. This means that x(x+5)=891, which can be rewritten as x^2+5x+891=0
D) Let x be the smaller number, and then x+5 is the larger number, This means that x+5/x=891, which can be rewritten as 890x-5=0
Answer:
you figure it out
Step-by-step explanation:
Number one is going to be N1
Number two is going to be N2
Product of the two numbers combined is going to be 891
N1= N2 +5
N1 + N2 = 891
(N2+5) + N2 = 891
N2 +5 +N2 =891
2N2 + 5 =891
im gonna let you figure the rest out

Answer:
The second choice
Step-by-step explanation:
Perimeter is calculated by adding the length and width but multiplied by 2. You add 3.2 and 1.5 and get 4.7. Multiply 4.7 by 2 would give you 9.4.
Area is multiplying the length and width. 3.2 multiplied by 1.5 would be 4.8

How do u write 0.57 repeating as a fraction in simplest form explain the steps please!
Answer:
57/99
Step-by-step explanation:
let's set up an equation:
x = 0.5757...
set up a second equation so the numbers after the decimal places are equal
100x = 57.5757...
subtract
100x = 57.5757...
- x = 0.5757
99x = 57
divide by 99
x = 57/99
0.57 repeating can be expressed as the fraction 19/33 in simplest form.
We have,
Let x = 0.575757... (with 57 repeatings)
Multiplying x by 100,
100x = 57.575757...
Subtracting the original x from 100x,
100x - x = 57.575757... - 0.575757...
99x = 57
To obtain x, divide both sides by 99:
x = 57/99
Dividing both the numerator and denominator by 3,
x = (57/3) / (99/3)
x = 19/33
Therefore,
0.57 repeating can be expressed as the fraction 19/33 in simplest form.

M is the midpoint of RT. RM = 5x + 9 and MT = 8x - 36. Find x, RM, MT, and RT. = .
The values of x, RM, RT, and MT are 15, 84, 168, and 84 respectively.
What is a System of equations?simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given a system of equations Where RM = 5x + 9 and MT = 8x - 36.
Since,
M is the midpoint of RT
Thus,
RM = MT
5x + 9 = 8x - 36
3x = 45
x = 15
So,
1) RM = 5x + 9
RM = 75 + 9 = 84
2) MT = 8x -36
MT = 120 - 36 = 84
3) RT = RM + MT
RT = 84 +84 = 168
Therefore, The values of x, RM, RT, and MT are 15, 84, 168, and 84 respectively.
