How to do 13-4x=1-x also show all steps?

1 answer:

3 0

<span>Given :13-4x=1-x
Solution :
-4x+x=1-13 ( transfer -x to right side and change the sign from - to + ,the number 13 also when we transfer to the
left side you must change the sign from + to - ,then add of the the same sign the different sign
minus the bigger number will carry the sign)
-3x=-12
-3x/-3 = -12/-3 ( in order to get the x you divide the same number and sign both sides)
X = 4 answer</span>

51.24 * 7.18 round each factor to its greatest place

mezya [45]

Answer:by mathatube

Step-by-step explanation:

What does greatest place value mean?

THE GREATEST OR HIGHEST PLACE VALUE IS THE DIGIT FARTHEST TO THE LEFT IN A NUMBER. IT COULD BE ANY NUMBER EXCEPT ZERO.

LOOK AT THE NUMBER 3654. The 3 is the greatest or highest place value number because it is the digit farthest to the left. The 3 is in the thousands place.

Look at the number again with a zero. 03654. The 3 is still the largest place value number because zero does not count.

Following the rules for Rounding

After finding the greatest place value number you can use the rules for rounding and round the number.

Example 1: round 24,356 the greatest place value.

Look to the right of the number in the ten

thousands place. It's a 4, so Round down.

24,356 is rounded to 20,000 because the highest

place value of that number is in the ten thousand

place.

Example-2: round 8,636 to the greatest place value.

8 is the number farthest to the left so it is the greatest place value number and it is in the thousands place

So look to the right of the number in the thousands

place. It's a 6, so round up.

8,636 is rounded up to 9,000 because the highest place value of that number is the 8 in the thousands place.

Complete the description of the piecewise function graphed below. Use interval notation to indicate intervals.

Gemiola [76]

Answer:

{ -2 if x ∈ -4 < x < -3

{ -5 if x ∈ -3 ≤ x < 2

[ 5 if x ∈ 2 ≤ x < 5

Step-by-step explanation:

From the graph, we have;

{ -2 if x ∈ -4 < x < -3

For the next inequality line at y = -5, we have;

1) The inequality line, starts with an open circle on the left at x = -3, which is equivalent to less than or equal to symbol, ≤ as -3 ≤ x because the point x =-3 is the left boundary. The inequality line extends to the point x = 2, where we have a closed circle (on the right), which is equivalent to a x ≤ 2 with the 2 on the right hand side because, the 2 is the right boundary of the inequality

2) The inequality can be summarized as starting from x = -3 extends to x = 2

3) As stated in point 1) the point x = 3, we have -3 ≤ x and at point x = 2, we have x ≤ 3 which can be combined as -3 ≤ x < 2, to give;

{ -5 if x ∈ -3 ≤ x < 2

For the next inequality line at y = 5, we have;

1) The inequality line, starts with an open circle on the left at x = 2, which is equivalent to less than or equal to symbol, ≤ as 2 ≤ x because the point x =2 is the left boundary. The inequality line extends to the right to reach point x = 5, where we have a closed circle (on the right), which is equivalent to a x ≤ 5 inequality, with the 5 on the right hand side because, the 5 is the right boundary of the inequality

2) The inequality can be summarized as starting from x = 2 extends to x = 5

3) As stated in point 1) the point x = 2, we have 2 ≤ x and at point x = 5, we have x ≤ 5 which can be combined as 2 ≤ x < 5, to give;

[ 5 if x ∈ 2 ≤ x < 5.

How can i learn times faster like 3's til 12's in Times i have a hard time in my times can someone tell me how i can learn them

iogann1982 [59]

To get better at 12's:
Write down on your paper your 1's facts in column skip 5 and 11 going to 14 (a vertical line - line that goes up and down). To the right of that column, write your two's facts 0 to 8 and repeat again. Then you will have your 12's! Should look as follows

12's:

0 0 = 12 x0
1 2 = 12 x1
2 4 = 12 x2
3 6 = 12 x3
4 8 = 12 x4
6 0 = 12 x5
7 2 = 12 x6
8 4 = 12 x7
9 6 = 12 x8
10 8 = 12 x9
12 0 = 12 x10
13 2 = 12 x 11
14 4 = 12 x 12
