Answer:
x = 19/4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-6 + 4x = 13
Step 2: Solve for x
Add 6 to both sides: 4x = 19Divide both sides by 4: x = 19/4Step 3: Check
Plug in x to verify it's a solution.
Substitute: -6 + 4(19/4) = 13Multiply: -6 + 19 = 13Add: 13 = 13Here, we see that 13 does indeed equal 13.
∴ x = 19/4 is a solution of the equation.
If you had 1 day to do anything... what would it be?
Answer: Simple. All the things that I could possibly do.
There are many wishes that I hold and with the opportunity given to do anything for one day, who knows what I could do?

Another thing is to have as much fun as I can. Be able to go somewhere or to visit something, that would be really nice. of course there are more things that I'd like to do but it would just be too much to list. :)

Sally left the city for vacation. Sandy left six hours later going 82 miles faster to catch up. After 5 hours Sandy caught up. What was Sally's average speed?
Answer: It took Sandy 11 hours to travel the same distance that Sam took 5 hours. {{{R[s]*11=5*75}}}
{{{R[s]=(5/11)*75}}}
{{{R[s]=34.9}}}{{{mph}}}
Don't ask sometimes i don't make sense...
The final answer is 11 hours... Hope this helps... Stay safe and have a great weekend!!! :D
Answer:
68 1/3
Step-by-step explanation:
Going 82 mph faster for 5 hours, Mary closed a (82 mi/h)×(5 h) = 410 mile gap. That gap was created in 3 hours by Sandy going.
(410 mi)/(6 h) = 68 1/3 mi/h

15.9-8.92 I suck at decimals
Answer:
6.98
Step-by-step explanation:
The answer would be 6.98 after subtracting 8.92 from the 15.9 after applying arithmetic operation.
What are arithmetic operations?The study of numbers and their operations, which are relevant to all other fields of mathematics, is part of the discipline of arithmetic operations. Addition, subtraction, multiplication, and division are the basic operations that make up this system.
It is given that:
The number expression is:
= 15.9-8.92
As we know from the definition of the arithmetic operation: Addition, subtraction, multiplication, and division are the basic operations that make up this system.
In the expression subtract 8.92 from the 15.9
After applying the arithmetic operation:
= 6.98
Thus, the answer would be 6.98 after subtracting 8.92 from the 15.9 after applying the arithmetic operation.

A clothing store is advertising t-shirts on sale for (x-3) dollars and skirts for (x + 6) dollars. Write an expression that represents the cost of 5 t-shirts and 3 skirts.
Answer:
8x + 3
Step-by-step explanation:
The cost of 5 t-shirts and 3 skirts
= 5(x - 3) + 3(x + 6)
= 5x - 15 + 3x + 18
= (5x + 3x) + (-15 + 18)
= 8x + 3

Give your answer as an improper fraction.
Answer:
x=19
Step-by-step explanation:
Basic Algebra.
x - 13 = 6
Simply move the 13 to the right side.
This involves changing the sign to positive, due to it being a negative integer.
The resulting outcome is
x = 13+6
Which concludes to
x=19
Jude researched the prices of several different models of cell phones and made a scatter plot of his data. The equation of the line of best fit for Jude’s data is p = -2.76t + 99.05 , where p is the price of the phone and t is the number of months that the phone has been available. What is the real-world meaning of the slope of this line?
a:A phone’s price increases by about $2.76 each month that it is available.
b:The original price of each phone was $2.76.
c:A phone’s price decreases by about $2.76 each month that it is available.
d:The original price of each phone was $99.05.
Answer:$4.76 each month
Step-by-step explanation:
A phone's price decreases by about $4.76 each month that it is available.
What is the y-intercept of the line y + 11=2(x+1.5)
Answer:
-8
Step-by-step explanation:
Turn the equation into slope intercept form [ y = mx + b ]
y + 11 = 2(x + 1.5)
~Distribute right side
y + 11 = 2x + 3
~Subtract 11 to both sides
y = 2x - 8
"b" represents the y-intercept, so, the y-intercept is -8.

A warehouse store sells 4.5-ounce cans of tuna in packages of 3. A package of 3 cans costs $4.32. The store also sells 3.5-ounce cans of the same tuna in packages of 4. A package of 4 cans costs $3.92. The store sells 6.5-ounce cans in packages of 5 cans for $9.75. Which package is the best buy?
Answer:
The 6.5-ounce cans offer the largest size at a fair cost and is the best to buy.
Step-by-step explanation:
Size of the 4.5-ounce cans of tuna in package = 4.5 × 3 = 13.5 ounce
Cost of the package= $4.32
Size of the 3.5-ounce cans = 3.5 × 4 = 14 ounce
Cost of the package= $3.92
Size of the 6.5-ounce cans = 6.5 × 5 = 32.5 ounce
Cost of the package= $9.75
The 6.5-ounce cans offer the largest size and is the best to buy.

Geometry Help huryyy!(pls right answers only) :(
Answer:
SRQ=24°
QTS=30°
RST=60°
RSQ=30°
Step-by-step explanation:
All angles in a triangle will always=180.
First we will find RQT
30+24+Q=180
Subtract 54 from each side
Q=126
Since All lines meet in the middle at Q, then each if those angle measures are equal.
We'll find SRQ first:
We don't know S but we know R is 24 and Q is 126
126+24+S=180
subtract 150
S=30°
QTS:
It tells us that T is 70° so that's all we need for this
RST:
We found half of S which was 30, so 30•2= 60 so RST=60
RSQ:
We already found the half of S which was 30°

Brianna bought a sandwich, apple, and cookie for lunch. The total was $5. if a sandwich costs six times more than the cookie, and an apple costs three times more than the cookie, how much does each item cost?
Answer:
Cookie=0.5, Apple=1.5, sandwich= 3
Step-by-step explanation:
Lets say cookie = x, then sandwich = 6x since sandwich is 6 times more expensive, apple = 3x. function: 6x+3x+x =5
10x=5
x=0.5
Answer:
The cookie costs $0.50, the apple costs $1.50, and the sandwich costs $3.
Step-by-step explanation:
I multiplied 0.50 by 3 (for the apple) and got 1.50, then I multiplied 0.50 by 6 (for the sandwich) and got 3. I then added them all together and got 5.

scrie toti multiplii de trei cifre distincte ai numarului 5, care se pot forma cu cifrele: a) 5, 7 si 8; b) 0, 3 si 5. repede va roggg
Answer:
I will answer in English.
Here, we want to find all the 3-digit multiples of 5, that can be formed with the digits:
a) 5, 7, and 8. (i suppose that we can not repeat the digits)
First, we know that all the multiples of 5 end with a 5 or a 0, then the possible ones here are:
875
785
(the five must always be at the end)
b) 0, 3, and 5.
Now we have two options, if the 5 is at the end, we have:
305
(035 is not an option, because is a 2-digit number).
if 0 is at the end, we have:
350
530
The volume of a cube is 1.5 m3. Find the length of its edge to the nearest tenth of a meter.
Given:
Volume of a cube = 1.5 m³
To find:
The length of its edge to the nearest tenth of a meter.
Solution:
Let a be the length of its edge.
We know that, volume of a cube is
[tex]V=a^3[/tex]
where, a is edge.
Volume of a cube = 1.5 m³
[tex]a^3=1.5[/tex]
Taking cube root on both sides, we get
[tex]a=\sqrt[3]{1.5}[/tex]
[tex]a=1.14471424[/tex]
Approximate the value to the nearest tenth (one decimal place) of a meter.
[tex]a\approx 1.1[/tex]
Therefore, the length of the edge of the cube is about 1.1 meters.
Find the x-intercept(s) and the coordinates of the vertex for the parabola =y−x2−4x5. If there is more than one x-intercept, separate them with commas.
x-Intercept(s):
Vertex:
Answer:
x-intercepts -1, 5.
Vertex is at (2, -9).
Step-by-step explanation:
y = x^2 - 4x - 5
Completing the square:
y = (x - 2)^2 - 2^2 - 5
y = (x - 2)^2 - 9 which is vertex form.
So the coordinate of the vertex are (2, -9).
Finding the x-intercepts:
(x - 2)^2 - 9 = 0
(x - 2)^2 = 9
x - 2 = +/- 3
x = 3 + 2 or -3+2
= 5, -1.
