Answer:

1. c) Add/ Subtract the same quantity to/from both sides

2) Yes

Step-by-step explanation:

Answer two questions about Equations A and B:

A. 3x – 1= 7

B. Зx = 8

1) To get Equation B from Equation A we need to take the following steps

A. 3x – 1 = 7

We add one to both sides

3x - 1 + 1 = 7 + 1

3x - 0 = 8

3x = 8

Option c is the correct option.

2) We are given Equations:

A. 3x – 1= 7

B. Зx = 8

3x - 1 = 7 = 3x = 8

3x = 7 + 1 = 3x = 8

3x = 8 = 3x = 8

Therefore, we can say, Yes, Equation A is equivalent to Equation B, hence they have the same solution.

PilotLPTM [1.2K]

Answer:

$251

Step-by-step explanation:

To get this amount, we simply find o.4% of 250.

That equals 0.4/100 × 250 = 1.

This means she would have earned an interest amounting to $1 after the first month.

The total amount of money in her account after the first month = 250 + 1 = 251

Hence, she would have an amount of $251 in her account after the first month.

The largest part of landfills is made up of newspapers. A 30.48 cm stack of newspapers weighs about 15.87 kg. How many grams doe

Helga [31]

First find how many grams are in 15.87kg and how many meters are in 30.48cm

15.87kg x 1000g/kg = 15, 870g
30.49cm x 1m/100cm = 0.3049m

Then, set up a proportion.

0.3049m/15, 870g = 1m/x g

Cross multiply to get..
0.3049x = 15, 870

Divide for x and there you are.Source(s):Myself.1004 · 8 years ago
