If it is :

10 -  \frac{ (3x - 1)}{2} =  \frac{(6x + 3)}{11} \\

Multiply both sides by 22

(22 \times  10) - 11 \times (3x - 1) = 2 \times (6x + 3) \\

220   -  33x  +  11 = 12x + 6

- 33x + 231 = 12x + 6

Plus both sides <em>3</em><em>3</em><em>x</em>

231 = 33x + 12x + 6

231 = 45x + 6

Subtract sides minus 6

231 - 6 = 45x

45x = 225

Divided sides by 45

x =  \frac{225}{45} \\

x = 5

_________________________________

If it is :

\frac{10 - (3x - 1)}{2} =  \frac{6x + 3}{11} \\

Multiply sides by 22

(11 \times 10) - 11 \times (3x - 1) = 2 \times (6x + 3) \\

110 - 33x + 11 = 12x + 6

- 33x + 121 = 12x + 6

Plus sides <em>3</em><em>3</em><em>x</em>

121 = 12x + 33x + 6

121 = 45x + 6

Subtract sides minus 6

121 - 6 = 45x

45x = 115

x =  \frac{115}{45} \\

x =  \frac{23}{9} \\

And we're done.

Thanks for watching buddy good luck.

How to check division with multplication<br><img src="https://tex.z-dn.net/?f=3%20%5Ctimes%20292%20" id="TexFormula1" title="3 \
svetoff [14.1K]

Answer:  By cross multiplication.

Step-by-step explanation:  Given product is 3 × 292.

We know that after simple multiplication, we get  3 × 292 = 876.

Now, to check division with multiplication, either we need to divide 876 by 3 to get the answer 292,

or

we need to divide 876 by 292 to get the answer 3.

We will do that as follows -

\dfrac{876}{3}=292~~~\textup{and}~~~\dfrac{876}{292}=3.

Thus, doing cross-multiplication, we arrive at our conclusion.

You are planning to work in the summer (13 weeks). You
Llana [10]

Answer:

(a) Equations for both

y = 500 + 12x --- lifeguard

y = 15x --- camp counselor

(b) Total pay for 5 days

Lifeguard pays $800

Camp counselor pays $375

(c) Which pays more

Lifeguard job pays more

Step-by-step explanation:

Let

x \to hours

y \to total\ pay

Given

Lifeguard job

Signing\ bonus = \$500

Rate = \$12/hr

Camp counselor job

Signing\ bonus =\$0

Rate = \$15/hr

Solving (a): The equation for both

The total pay for each job is calculated as:

Total Pay = Signing Bonus + Rate * Hours

So, we have:

Lifeguard

y = 500 + 12*x

y = 500 + 12x

Camp counselor

y = 0 + 15 * x

y = 15x

Solving (b): Total pay for 5 days

First, we calculate the total hours worked in 5 days

x = 5hrs/day * 5days

x = 25hrs

So, the pay for each is:

y = 500 + 12x

y =500 + 12*25

y =800 --- Lifeguard

y = 15x

y = 15 * 25

y = 375 --- camp counselor

Solving (c): Which job pays more

By comparing the solution in (b)

800 > 375

<em>Hence, lifeguard job pays more</em>

Consider the following pair of equations:
V125BC [204]
The pair of equations:
y = x + 4
y = -2x - 2

To solve the system of equation by substitution, you would substitute one variable for it's equivalent expression. Combining the pair of equations into one equation in only one variable. The easiest way to do this is by substituting out the variable y because it is already alone on one side of the equal sign. Substitute the y in the second equation for: x+4

x+4 = -2x - 2
solve for x
x + 2x = -2 -4
3x = -6
x = -2

now use the value for x to find y by putting into either equation.

y = x + 4
y = (-2) + 4
y = 2

solution is: (-2, 2)

Which correlation coefficient best represents a moderate relationship showing fewer anxiety symptoms in people who report higher
weqwewe [10]

Answer:

a) -0.5

Step-by-step explanation:

Correlation

  • Correlation is a technique that help us to find or define a relationship between two variables.
  • It is a measure of linear relationship between two quantities.
  • A positive correlation means that an increase in one quantity leads to an increase in another quantity
  • A negative correlation means with increase in one quantity the other quantity decreases.
  • Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.

Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.

Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5
