Answer:

see explanation

Step-by-step explanation:

(a)

To change a mixed number to an improper fraction

Multiply the whole number by the denominator of the fraction and add the numerator. This value is the numerator of the improper fraction while the denominator remains unchanged, that is

(2 × 13) + 12 = 26 + 12 = 38 ← numerator

2 $\frac{12}{13}$ = $\frac{38}{13}$

(b)

To change an improper fraction to a mixed number

divide the numerator by the denominator, noting the remainder, which forms the numerator of the fraction in the mixed number.

$\frac{47}{19}$ = 2 remainder 9, hence

$\frac{47}{19}$ = 2 $\frac{9}{19}$

Consider the compound inequality x < 4 and x>a. If a=4 and the compounding word were "or" instead of "and",what would the

FinnZ [79.3K]

Answer:

We have:

x < 4 AND x > a.

if a = 4 and we use an "or" instead of the "and" we have:

x < 4 or x > 4.

This is:

"x is larger than 4 or smaller than 4."

Then the solution of this is all the real numbers except the value x = 4.

The set of solutions can be written as:

{xI x ∈ R \ [4]}

Where this reads:

"x belongs to the set of the reals minus the number 4".

Or we also could write it as:

x ∈ (-∞, 4) ∪ (4, ∞)

Where we have two open ends in the "4" side, so the value x = 4 does not belong to that set.

for these scenarios, write equations or inequalities that reflect the relationship. The minimum number of hours required to rent

IgorLugansk [536]

Answer:

$100 + 35x \geq 280$ is the inequality that reflect the relationship.

Step-by-step explanation:

Given:

Charge for rental = $100

Additional charge = $ 35

Minimum amount that can be spent = $280

To Find:

equations or inequalities that reflect the relationship = ?

Solution:

Let x be the minimum number of hours

then the charge will be

100 + (number of hours)(additional cost per hour)

That is

100 + 35x

Now the minimum charge amount is $280 So, The charge can be 280 or more than 280

$100 + 35x \geq 280$

Will get brainliest!!!!!!!!!!! <br>1 − 3(3 + 6b) = −6(3b + 1) − 2

Arlecino [84]

Answer:

b = infinity

Step-by-step explanation:

1 − 3(3 + 6b) = −6(3b + 1) − 2

1 - 9 - 18b = -18b + 1 -2

1 - 9 = 1 - 2

-8 = -1
