4 + 4x = -5(x - 8)
Solve Multi-Step equation.
Please explain how you i can understand too!
Answer:
If solving for x its
4 + 4x = -5(x - 8) (side math --> -5x +40)
-4. = -4
4x = -5x + 36
+5x = +5x
9x = 36
÷ ÷ (by 9)
x = 4
Step-by-step explanation:
Each equation solution, brings down another answer, making this equal x=4

can anyone help me with this, with a full explanation ?? thank you
Step-by-step explanation:
let the 3 consecutive odd number be
x + 1 , x + 3 , x + 5
as, there sum is 45. so, after inserting the values we got,
→ x + x + 1 + x + 3 = 45
→ 3x + 9 = 45
→ 3x = 45 - 9 = 36
→ x = 36/3 = 12
→ x = 12
therefore, 3 consecutive odd number are
→ x + 1 = 12 + 1 = 13
→ x + 3 = 12 + 3 = 15
→ x + 5 = 12 + 5 = 17

Answer:
[tex]1~3/4[/tex]
Step-by-step explanation:
Let [tex]k[/tex] be the amount of pork Mike uses. Then, he uses [tex]3k[/tex] beef.
We know he uses 7 pounds, of meat so we want to solve [tex]3k+k=7[/tex].
Combining like terms on the left side gives [tex]4k=7[/tex].
We can divide both sides by [tex]4[/tex] to get [tex]k=7/4=1~3/4[/tex].
So, the answer is [tex]\boxed{1~3/4}[/tex].
What is the best choice for the common denominator in this problem?
1/5 + 2/6
Answer:
The common denominator is x30
Step-by-step explanation:
Answer:
[tex]30[/tex]
Step-by-step explanation:
The best choice for a common denominator will always be the least common multiple of the two denominators. In this case, the least common multiple of 5 and 6 is 30, so [tex]\boxed{30}[/tex] is the best choice.
The LCM of two numbers is the lowest integer that divides them both evenly
A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails and each large box has 400 nails. The contractor bought 2 more small boxes than large boxes, which altogether had 1950 nails. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.
Answer:
The number of small and large boxes purchased are:
2 small boxes.
6 large boxes.
Step-by-step explanation:
To solve the unknowns, two equations must be established with the information provided:
150X + 400Y = 2700 (the price of the boxes and the final number of nails, where X is the small boxes and Y the large boxes)
Y = 3X (Large boxes are triple the small ones)
Then equation 2 is replaced in equation one and variable X is cleared:
150X + 400 (3X) = 2700
150X + 1200X = 2700
1350X = 2700
X = 2700/1350
X = 2
Finally, the value of X is replaced in equation 2 to find the number of large boxes:
Y = 3X
Y = 3 (2)
Y = 6

Lesson 3-8. Write an equation for the line perpendicular to the given line through the given point.
Answer:
y = -3x + 14Step-by-step explanation:
Given line:
y = 1/3x - 2/5Perpendicular lines have negative-reciprocal slopes.
We will have a line:
y = -3x + bUse the coordinates of the given point to find the value of b:
-1 = -3(5) + b-1 = - 15 + bb = 14So the line is:
y = -3x + 14what is the answer to: − 2 − 1 3 . 8 = − 8 − ( 6 + 1 )?
I hate sails math- like what is the point of it? -_-
Answer:
The only math I see having a point is basic math like addition subtraction multiplication and division, unless you are going for a job that requires ALOT of harder math.
solve for y
2x+3y=r
(Show solving steps please)
2x + 3y = r
---Subtract 2x from both sides
3y = r - 2x
---Divide both sides by 3
y = (1/3)(r) - (2/3)(x)

The circle graph below shows the results of a survey. Of those surveyed, 20 said no. About how many people were surveyed?
Answer:
50 people
Step-by-step explanation:
20 / .4 = 50
if 40% = 20
then 20% = 10
therefore 60% = 20% *3
60% = 10 * 3
60% = 30 people

Answer:
[tex] \pi \: 4 \: 8[/tex]
Answer:
[tex]\pi, 4, 8[/tex]
Step-by-step explanation:
Note that [tex]\pi\approx3.14[/tex]. As [tex]3<3.14<4[/tex], [tex]\pi[/tex] comes before [tex]4[/tex].
Clearly [tex]4<8[/tex], so [tex]4[/tex] comes before [tex]8[/tex].
The only possible ordering is [tex]\boxed{\pi, 4, 8}[/tex]
suppose another line for a chair lift is placed at a constant distance c below the gondola line. what is the equation of the new line? is the new line also parallel to the hill? explain.
Answer:
Yes They are Parallel.
Step-by-step explanation:
The required equation of the line y = ax + c as of the old line and also the line is parallel to the hill.
Given that,
Suppose another line for a chair lift is placed at a constant distance c below the gondola line. the equation of the new line and is the line parallel to the hill is to be discussed.
A line is a straight curve connecting two points or more showing the shortest distance between the initial and final points.
Here,
The required new line is placed at a constant distance c below the gondola line,
If the line has a constant distance from the other line that implies that the line is parallel, and the equation of the line is given as,
y = ax + c
Thus, the required equation of the line y = ax + c as of the old line and also the line is parallel to the hill.

Prove the following relations: 1) (1 - cos²A) (1 + tan²A) = tan²A
Step-by-step explanation:
(1 - cos²A)(1 + tan²A) = tan²A
1 + tan²A - cos²A - cos²A · tan²A = tan²A
1 + tan²A(1 - cos²A) - cos²A = tan²A
1 - cos²A + tan²A(sin²A) = tan²A
sin²A + tan²A(sin²A) = tan²A
sin²A (1 + tan²A) = tan²A
sin²A (sec²A) = tan²A
sin²A (1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → Proved

A. Find the indicated number of geometric mean/s between the given two numbers.
1. 5 and 20 [ 1 term ]
2. 8 and 512 [2 terms]
3. 2 and 50 [ 1 term ]
4. 6 and 486 [3 terms]
5. 4 and 108 [2 terms]
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The ratio of the given terms is the common ratio raised to a power equal to the number of means plus 1.
1)For example, the common ratio in the sequence 5, __, 20 will be r, where ...
r^2 = 20/5 = 4 ⇒ r = 4^(1/2) = 2
Then the mean is found by multiplying 5 by this ratio: 5×2 = 10.
__
2-5)The same method is used for finding the common ratio and then the intermediate means. Each mean is the previous term multiplied by the common ratio. Results are summarized in the attached table.

Find the Inverse function F(x)=4x-6
y = 4x - 6
x = 4y - 6; must solve for y in order to solve for inverse function
x + 6 = 4y
(x + 6)/4 = y
or
(x/4) + (6/4) = y
y = (x/4) + 3/2

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
