5(x+6)-2x=3(x+10) solve for x
Answer:
x=all real numbers
Step-by-step explanation:
1. distribute: 5(x+6)-2x=3(x+10)
5x+30-2x=3x+30
2. combine like terms 3x+30=3x=30
3. these are equal therefore x=all real numbers

It takes Roberto eight hours longer than Paula to repair a transmission. If it takes three hours to do the job if they work together, how long will it take each of them working alone?
Answer:
Paula = 4 hours
Roberto = 12 hours
Step-by-step explanation:
Time taken by Paula = x
Time taken by Roberto = x +. 8
Paula's rate = 1/x
Roberto's rate = 1/(x + 8)
Combined rate = 1/3
Time it takes each if them working alone ;
Paula's rate + Roberto's rate = combined rate
1 /x + 1 / (x +8) = 1/3
Take the L. C. M
((x+8) + x) / x(x+8) = 1/3
(2x + 8) / x(x + 8) = 1/3
3(2x + 8) = x(x + 8)
6x + 24 = x² + 8x
x² + 8x - 6x - 24 = 0
x² + 2x - 24 = 0
Solving the quadratic equation :
x² + 6x - 4x - 24 = 0
x(x + 6) - 4(x + 6) = 0
(x - 4) = 0 or (x + 6) = 0
x = 4 or x = - 6
Time taken cannot be negative
Hence, x = 4
Hence, working alone, it takes ;
Time taken by Paula = 4
Time taken by Roberto = 4 + 8 = 12

What type of number is square root 2 (I put in square root because I don´t have a square root symbol, its kinda like this /```` almost but a slant at the end)
What I mean by type of number is like whole number, rational, irrational, integer, what is it?
Answer:
Step-by-step explanation:
Rational numbers come in 3 different forms; integers, fractions and terminating or recurring decimals such as
1
3
.
Irrational numbers are quite 'messy'. They can't be written as fractions, they are never-ending, non-repeating decimals. An example of this is the value of
π
.
A whole number can be called an integer and is either a positive or negative number, or zero. An example of this is
0
,
1
and
−
365
.

What’s the slope of this ?
Step-by-step explanation:
The two given equations have slope -1/2 and 2 and are perpendicular lines.
The lines on the graph are different from the equations at left.
Their slopes are 2 and 1/2. Since they are not opposite reciprocals, they are not perpendicular.
Jacob and Melissa both collect baseball cards. Let J represent the number of cards that Jacob has. Melissa has 5 fewer cards than Jacob. Write an expression that shows how many cards they have together.
Answer: 2J - 5
Step-by-step explanation:
The number of cards that Jacob has = J
Melissa has 5 fewer cards than Jacob. Melissa card will be: = J - 5
The expression that shows the number of cards they have together will be gotten by adding their cards together. This will be:
= J + (J - 5)
= J + J - 5
= 2J - 5

yo can anyone tell me a expression with two terms, one variable and one coefficient. please ty.
Answer:
We conclude that the required expression with two terms, one variable, and one coefficient will be:
[tex]3x+4[/tex]Step-by-step explanation:
Consider the expression
[tex]3x+4[/tex]
Terms:
We know that a term is a single mathematical expression. The expression has two terms which are:
3x4Variable:
The expression has one variable which is:
xCoefficient:
We know that the coefficient is the number part of the term with a variable. Thus, the coefficient of the term 3x has one coefficient which is:
3Therefore, we conclude that the required expression with two terms, one variable, and one coefficient will be:
[tex]3x+4[/tex]In triangle XYZ, the measure of ∠Y is 64°. The measure of ∠Z is (3/4) the measure of ∠Y. What is the measure of ∠X?
Answer:
68°
Step-by-step explanation:
Calculation for What is the measure of ∠X
Measure of ∠X=180°−(64°+3/4×64°)
Measure of ∠X=180°−(64°+0.75×64°)
Measure of ∠X=180°−(64°+48°)
Measure of ∠X=180°−112°
Measure of ∠X=68°
Therefore the measure of ∠X will be 68°

Step-by-step explanation:
Multiply by 100.
213.6363...
Subtract the original.
213.6363... -2.1363... = 211.5
Divide this by 99.
211.5/99 = 2115/990 = 2 135/990 = 2 3/22
_____
The original number you multiply by is 10^n, where n is the number of repeating digits. Then the number you divide by is (10^n -1). Here, those values are 100 and 99, because there are 2 repeating digits.

To prepare for his mountain biking trip, Rhyan bought four tire patches. Rhyan paid using a gift card that had $22.20 on it. After the sale, Rhyan’s gift card had $1.90 remaining.
Which equations could you use to find the price of one tire patch? Select all that apply.
4x – 1.9 = 22.2
4x – 22.2 = 1.9
4x + 1.9 = 22.2
4x + 22.2 = –1.9
22.2 – 4x = 1.9

Answer:
Option (a)
Step-by-step explanation:
Since, can of the energy drink is in the form of a cylinder.
Volume of a cylinder is given by the formula,
V = πr²h
Here, r = radius of the can
h = height of the can
By substituting the values in the formula,
V = π([tex]\frac{1.5}{2}[/tex])²(7)
= (3.14)(0.75)²(7)
= 3.14(0.5625)(7)
= 12.36375 in³
≈ 12.36 in³
Therefore, Option (a) will be the correct option.
