Simplify 8d-6e - 3d + 4e.

Answers

Answer 1

Answer:

Answer: 5d-2e

Step-by-step explanation:

To solve this equation, we have to combine like terms. In this equation, we have two like terms, terms with the variable e, and terms with the variable d. So to combine the terms, we have to perform arithmetic operations.

In this case we only have to add and subtract.

So, -6e+4e=-2e (-6+4=2)

And, 8d-3d=5d (8-3=5)

Therefore, our answer is 5d-2e.

What is an expression?

A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression in mathematics.

Mathematical symbols can represent variables, operations, functions, brackets, punctuation, and grouping to help specify the logical syntax and order of operations.

But in contemporary mathematics, and particularly in computer algebra, formulae are seen as expressions that can be evaluated as true or false, depending on the values given to the variables present in the expressions.

In the garden, Israel sowed 4 tomato seeds. Then Israel scattered flower seeds throughout the gardens of the three neighbors. Here neighbors will be denoted as x. For this the most suitable expression will be 4 + 3s.

Therefore, Option B is correct.

Nastasha has a gross income of $66,429. She can make adjustments of $14,490 for business losses, $3,584 for business expenses, and $4,813 for contributions to her retirement plan. What is Nastasha’s adjusted gross income?a.
$109,971
b.
$22,887
c.
$72,522
d.
$43,542

Answers

Initial gross income = 66429

business losses = 14490
business expenses = 3584
retirement plan = 4813

Adjusted gross income
66429 - (14490+3584+4813)
66429 - 22887
43542

Therefore the answer d is correct

the answer would be D because

66,429-14,490=51939

51,939-3,584=48,355

48,355-4,813=43,542

A quarterly telephone bill consist of N$79.15 rental plus 4.7 cents for each dialled unit. Sales tax is added at 15%. What is the total bill for Mrs. Jones who used 915 dialled units?

Answers

Answer:

$140.48

Step-by-step explanation:

Let x represent dialed units.

We have been given that a quarterly telephone bill consist of $79.15 rental plus 4.7 cents for each dialed unit.

4.7 cents = $0.047

Cost of dialing x units would be $0.047x$ .

Total cost of dialing x units would be $0.047x+79.15$ .

Let us find cost of dialing 915 units by substituting $x=915$ in above expression.

$0.047(915)+79.15$

$43.005+79.15$

$122.155$

Now, we will find 15% of sales tax as:

$122.155* (15)/(100)$

$122.155* 0.15$

$18.32325$

Total bill: $18.32325+122.155=140.47825\approx 140.48$

Therefore, Mrs. Jonas's bill would be $140.48.

$4.7 × 915 = 4300.5
$4300.5 + 79.15 = 4379.65
15% of 4379.65 = 656.9475
4379.65 + 656.9745 = 5036.6245
Mrs. Jones' Bill was $5036.63
