1) 2x + 9 = 2x -5

9 ≠ -5 ; No solution

2) 2x- 1 = x + 3

x = 4; One solution x = 4

3) x + 2 = x + 2

0 = 0; Identity (or all real numbers)

X = 19.

Explanation:

This expression is vertical from the angle 135, meaning it is congruent. With that being said, we would need to find what 7 multiplies by to give us 2 less than 135, which would be 133. Because 133 divided by 7 equals 19, x = 19. If we plug this in, we get the following equation: 7(19) + 2 = 135.

13 + {16 + 2 -[25 + 45) x 3] + 9}

Goshia [24]

Answer: -170

Concept:

When encountering questions that require multiple steps of the calculation, it is suggested to follow the PEMDAS.

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Solve:

**Disclaimer** I assume that it is supposed to be (25 + 45). If it was, then you may refer to my answer. If the ")" after 45 is just a typo, you may point it out and I will redo it.

Given expression

13 + {16 + 2 - [(25 + 45) × 3] + 9}

Do the parenthesis of the inner most

=13 + {16 + 2 - [70 × 3] + 9}

=13 + {16 + 2 - 210 + 9}

Do addition first, then subtraction

=13 + {18 - 210 + 9}

=13 + {27 - 210}

=13 - 183

=-170

Hope this helps!! :)

Apple produce pays it's employees by the formula P(b)=7/2b+35, where P(b) is the employee's total daily pay and b is the number

Doss [256]

Answer:

Apple Produce pays employees 38.5 for per bushels of apples picked.

Step-by-step explanation:

Given:

Apple produce pays it's employees by the formula;

$P(b) = \frac{7}{2}b+35$

$P(b)$ ⇒ Employee's Total daily pay

$b$ ⇒ Number of bushels of apples

We need to find the Rate employees are paid per bushels of apples picked.

Rate employees are paid per bushels of apples picked can be calculated by substituting the value of "b = 1" in above formula.

Substituting the value of b = 1 in above formula we get;

$P(1) = \frac{7}{2} \times 1+35\\$

Now We will take LCM to make the Denominator common.

$P(1) = \frac{7}{2} +\frac{35\times 2}{2} = \frac{7}{2} +\frac{70}{2} = \frac{77}{2}= 38.5$

Hence Apple Produce pays employees 38.5 for per bushels of apples picked.
