Solve for x: 12x+5=3x+35
Answer:
The answer would be 3.33.
Step-by-step explanation:
Simplifying 12x + 5 = 3x + 35
Reorder the terms: 5 + 12x = 3x + 35
Reorder the terms: 5 + 12x = 35 + 3x
Solving 5 + 12x = 35 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation. 5 + 12x + -3x = 35 + 3x + -3x
Combine like terms: 12x + -3x = 9x 5 + 9x = 35 + 3x + -3x
Combine like terms: 3x + -3x = 0 5 + 9x = 35 + 0 5 + 9x = 35
Add '-5' to each side of the equation. 5 + -5 + 9x = 35 + -5
Combine like terms: 5 + -5 = 0 0 + 9x = 35 + -5 9x = 35 + -5
Combine like terms: 35 + -5 = 30 9x = 30
Divide each side by '9'. x = 3.333333333
Simplifying x = 3.333333333

Answer:
8
Step-by-step explanation:
The notation n=1 .. 8 means that n takes on all integer values from 1 to 8. Each value of n gives one term that is added to the series.
The number of terms is 8.
For the equation, complete the solution. 8x + y = −7
(x, y) = , 1
Answer:
(x, y) = (-1, 1)
Step-by-step explanation:
8x + y = −7
for y = 1
8x + 1 = -7
subtract 1 from boh sides
8x = -8
divide bot sides by 8
x = -1
(x, y) = (-1, 1)
the algebraic form of the sum of n terms of an arithmetic sequence is 3n2 + 5 n .what is the common difference ?
Answer:
[tex]d = 6[/tex]
Step-by-step explanation:
Given
[tex]S_n = 3n^2 + 5n[/tex]
Required
Find d
First, find the sum of the first 1 term
[tex]S_1 = 3 * 1^2 + 5 * 1[/tex]
[tex]S_1 = 8[/tex]
The sum of the first 2 terms
[tex]S_2 = 3 * 2^2 + 5 * 2[/tex]
[tex]S_2 = 22[/tex]
Calculate the first term (a)
[tex]a = S_1[/tex]
[tex]a = 8[/tex]
Calculate the second term (T2)
[tex]T_2 = S_2 - S_1[/tex]
[tex]T_2 = 22 - 8[/tex]
[tex]T_2 = 14[/tex]
The common difference is:
[tex]d = T_2 - a[/tex]
[tex]d = 14 - 8[/tex]
[tex]d = 6[/tex]

At the store, Alyssa spent $3.25 on stickers and $6.50 on candy. She paid with a $10 bill. How much change did she get back?
Answer:
$0.25
Step-by-step explanation:
First, find how much the stickers and candy cost in total:
3.25 + 6.50
= 9.75
Subtract this from 10 to find how much change she got back:
10 - 9.75
= 0.25
So, she got back $0.25 in change
what is the slope of p?
===========================================================
Explanation:
Start at the origin (0,0). Move 2 units up (rise) and move to the right 3 units (run) to arrive at the point (3,2).
This shows that the slope is rise/run = 2/3.
---------------------
You could also use the slope formula, which is,
m = (y2-y1)/(x2-x1)
You can use any two points from the orange line.

Write the following equation in standard form. Show your work. y =3/7x -2
Answer:
3x - 7y = 14
Step-by-step explanation:
standard form is: ax + by = c
first, add 2 to each side of the equation to get:
2 + y = 3/7x
now multiply each term by 7 to eliminate fraction:
14 + 7y = 3x
now subtract 7y from each side to get:
3x - 7y = 14

Answer:
172.8 m^3
Step-by-step explanation:
Volume for triangualr prism formula:
1/2 • length • width • height
Use formula with given dimensions:
1/2 • 7.2 m • 10 m • 4.8 m = 172.8
Volume is measured in cubic meters
(meters in this situation)
FINAL ANSWER:
172.8 cubic meters
Hope this helps!
The volume of the given prism is 172.8 cubic centimeters.
The given prism is a triangular prism with base length of 7.2m.
Height of 4.8m
Length of 10m.
The formula for volume of prism is V=1/2 bhl
Plug in the values of length , breadth and height:
V=(1/2) × 10 × 4.8 × 7.2
V=5×4.8×7.2
V=172.8 cubic centimeters.

Answer:
0° < x < 83.76°
Step-by-step explanation:
Assuming a pyramid with a square base, and the height of the pyramid varies from almost zero to almost infinity.
The largest value for the angle x+2 is when the height of the pyramid is almost zero.
Then the face is an isosceles triangle with base 13 and height 14.
The angle opposite the base is then
x+2 = 2*atan(6.5/7) = 2* 42.879 = 85.76°
when the height is almost infinite, the angle is almost zero.
Therefore the range of the value of x
0° < x < 83.76°
