A set of equations is given below:Equation A: c = 2d + 1
Equation B: c = 3d + 5

Which of the following is a step that can be used to find the solution to the set of equations?

2d + 1 = 3d + 5
2d = 3d + 5
2d + 1 = 3d
2d + 5 = 3d + 1

Answers

Answer 1

Answer: If you would like to find a step that can be used to find the solution to the set of equations, you can do this using the following steps:

c = 2d + 1
c = 3d + 5
__________
c = c
2d + 1 = 3d + 5
2d - 3d = 5 - 1
- d = 4
d = -4

The correct result would be 2d + 1 = 3d + 5.

Answer 2

Answer:

Answer:

2d + 1 = 3d + 5

Find the product of 543.1187 and 100 A. 5.431187 B. 54,311.87 C. 5,431.187 D. 54.31187 Can someone also explain how they came up with the answer so that I can understand? (do you move the decimal? If so, to the left or right? How many times you move it?

Answers

$543.1187*100=\boxed{54311.87}$

When you're multiplying by a power of 10 such as 100, the decimal point moves two places to the right. Note that this corresponds with the number of zeroes in 100. Of course our number is going to get bigger, not smaller, which means we'd have to be going right. If we multiplied by something like 0.001, we'd also be going two places, just going smaller and to the left.

The answer would be 543.1187 X 100= {54311.87}

Anna invests $875 into an account and receives 4% simple interest for 24 months. How much simple interest will she earn??

Answers

Answer:

$70

Step-by-step explanation:

1. I = PRT

2. Sub in what you know into the equation:

I = $875 (principal amount) x 0.04 (4%) x 2 (24 months = 2 years)

3. 875 x 0.04 x 2 = 70

4. Anna will receive $70 in simple interest

Answer:

£70

Step-by-step explanation:

simple interest (I) is calculated as

I = $(PRT)/(100)$

where P is principal, R is rate of interest and T is time in years.

Note that 24 months = 2 years, thus

I = $(875(4)(2))/(100)$ = $(7000)/(100)$ = £70

Finish the sequence 1,1,1,3,5,9,17,31,57, , ,

Answers

Your basically adding the first 3 numbers to get the next for example: 1,1,1=3
and then 1,1,3,=5 and then 1,3,5=9 then 3,5,9 =17 so on and so forth.

so to get the first answer of 105 I added the last 3 numbers in the sequence together (17,31,57) to get 105

the next 3 numbers in the sequence are:
105,193,355
