Step 1:
7x + 5x - 7 = 21 + 10x Equation
Step 2:
12x - 7 = 21 + 10x Add
Step 3:
2x - 7 = 21 Subtract 10x on both sides
Step 4:
2x = 28 Add 7 on boths sides
Step 5:
28 ÷ 4 Divide
Answer:
x = 7

Order the numbers from closest to zero to farthest from zero:
4.38, l4.5l, l-4.6l, -l4.9l
HELPPPPP
The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.
With that being said, here is the order of the numbers from smallest to largest:
4.38
4.5
4.6
4.9
Answer:
Here are the numbers ordered from closest to zero to farthest from zero:
4.38 (closest to zero)
4.5
-4.6
-4.9 (farthest from zero)

Step-by-step explanation:
I know this answer is right because the numbers got larger as the letters went to the right which means increase and the answers and graph makes logical sense to me. Hopefully you get a good grade on this.
Answer:
The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
step by step:
From the number line we can observed that:
1) A, B, C and D lies between -1 and 0.
2) Point A and B lies between -1 and -0.5
3) Point C and D lies between -0.5 and 0
Therefore, the value of A and B must have a negative value lying between -1 and -0.5
Also, the value of C and D must have a negative value lying between -0.5 and 0.
Now consider the provided options.
Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16
This is Incorrect representation because the value of A and B should lying between -1 and -0.5.
Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7
This is Incorrect representation because the value of C and D should lying between -0.5 and 0.
Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16
Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.
Also they are in ascending order from -1 to 0.
Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

What is 19.2×108 minutes in hours?
3.200×109 h
3.200×107 h
1.152×1011 h
1.152×107 h
Answer:
3.200×107 h
Step-by-step explanation:
The graph shows the number of hours that Tammy spends typing for work, x, and the amount of pay that she earns, y.
On a graph titled Tammy's Pay, number of hours is on the x-axis and pay in dollars is on the y-axis. A line goes through points (2, 18) and (8, 42).
What does the y-intercept represent?
Answer: The y-intercept is the initial amount Tammy earns.
Step-by-step explanation:
Always remember that for graphs, the y-intercept is the initial amount. In this case, it would be the initial amount or the very first amount Tammy earns. If the line goes through the origin (0,0), that means that Tammy earns $0.00 for 0 hours of working.
How do I determine the little numbers on the top of the answer in the standard algorithm, WITHOUT HAVING TO DO THE STANDARD ALGORITHM (because I already solved it, but I don;t know the the little numbers on top)
Answer:
The standard algorithm for addition has three simple rules:
Rule 1: Line up the numbers vertically by matching the place values - and start with the ones place.
To explain: When you add multi-digit numbers, the problem is typically written vertically - meaning one set of numbers is on top of the other. But, you can't just place the numbers anywhere - there is a proper placement of the numbers based upon place value. Place value is the place a number represents when a number is written in standard form. We will look at an example after we review the rest of the rules.
Rule 2: Add together the numbers that share the same place value - again, start with the ones place.

1/3; 2/3
1/2; 1/2
5/6; 1/2
1/6; 5/6
Brainlist for positive attitude and correct answer :D
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D
