If 16x-2=30 what is the value of 8x-4?

Answers

Answer 1
12 is the value of 8x-4 when 16x-2=30
16x - 2 = 30
+ 2 +2
16x = 32 , x=2
Substitute :
8x - 4 = 8(2) - 4 = 16-4 = 12!
Answer 2

Answer:

12

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define 1st equation

16x - 2 = 30

Step 2: Solve for x

Add 2 on both sides:                    16x = 32Divide 16 on both sides:               x = 2

Step 3: Solve equation

Define:                    8x - 4Substitute:              8(2) - 4Multiply:                  16 - 4Subtract:                 12

And we have our final answer!

The Wildcats scored an average of 56 points per game during their four-game season. If the scores for their first three games were 48, 57, and 52, what was the score of their last game?

Answers

Answer:

67

Step-by-step explanation:

Use the average formula: average = sum of elements / number of elements

Let x represent the score of their last game, and plug in the average, other scores, and number of elements into the equation:

56 = (48 + 57 + 52 + x) / 4

Simplify:

56 = (157 + x) / 4

Solve for x, by first multiplying each side by 4:

224 = 157 + x

Subtract 157 from both sides:

67 = x

So, the score of their last game was 67.

A train leaves L.A. at 2pm and heads north at 50mph. If the next train leaves the station 3 hours later and heads north at 60 mph, what time will the second train catch up with the first?

Answers

Answer:

8 AM

Step-by-step explanation:

Start time = 2 PMSpeed of the first train = 50 mphSpeed of the second train = 60 mphTrains head same directionThe second train spends 3 hour less time than the first but both take same distance

Let the time in travel for the first train be x, then we have equation for distance:

50x = 60(x - 3)50x = 60x - 18060x - 50x = 18010x = 180x = 18 hours

Time when the second train caches up the first one:

2 PM + 18 hours = 8 AM next day

Each square in the grid is a unit square with an area of 1 square unit. What is the area of the figure? square units ​

Answers

Answer:

The total area of the figure is: 16 square units

Step-by-step explanation:

The Area is basically a measure of how much space in square units there is inside an object.

Given that each square in the grid is a unit square with an area of 1 square unit.

The figure clearly shows that there are 14 complete squares and 4 half square units.

Thus, the total area of the figure is:

(1 × 14) + (1/2 × 4)

=14 + 2

= 16 square units

Therefore, the total area of the figure is: 16 square units

Mr. Lester needs less than 12 cup but more than 13 cup of flour to make a sauce. Which of the following could be the amount of flour that he needs?
1/4 cup
7/12 cup
3/8 cup
7/8 cup

Answers

Answer:

3/8 cup

Step-by-step explanation:

To figure out how many cups of flour he could use, let's convert the fractions into decimals. We are told that amount he needs is less than 1/2 and more than 1/3.

1/2 = 0.50

1/3 = 0.33

So, the amount he needs is less than 0.50 and more than 0.33. Now let's convert the answer choices to decimal form:

1/4 = 0.25

7/12 = 0.58

3/8 = 0.38

7/8 = 0.88

The only answer choice that is less than 0.50 but greater than 0.33 is 0.38, or 3/8 cup.

C(-1,6);y=2/5x-2 what is the equation of the parallel lines.

Answers

9514 1404 393

Answer:

  y = 2/5x +32/5

Step-by-step explanation:

The given line is in slope-intercept form.

  y = mx + b . . . . . . m is the slope; b is the y-intercept

The value of the slope in the given line is m=2/5. A parallel line will have the same slope. In general, it will have a different y-intercept. That value can be found from the given point.

  y = 2/5x + b

  6 = 2/5(-1) +b

  6 +2/5 = b = 32/5

The equation of the parallel line through (-1, 6) is ...

  y = 2/5x +32/5

what is the slope of 1.5x+4.5y=18

Answers

Answer:

The x intercept is (12,0)

Step-by-step explanation:

1.5x+4.5y=18  Subtract 1.5 x from both sides of the equation

4.5y=-1.5x+18  Divide both sides of the equation by 4.5

4.5y/4.5=-1.5x/4.5+18/4.5

y=-1/3x+4

The slope is -1/3

The y intercept is (0,4)

To find the x intercept, yet y=0 and solve.

1.5x+4.5y=18

1.5x+4.5(0)=18

1.5x=18  Divide both sides of the equation by 1.5

1.5x/1.5=18/1.5

x=12

The slope is 1/3. You subtract 1.5x on both sides and you are left with 4.5y = 18-1.5x. Then you divide by 4.5 on both sides and you get y=4-1/3x. The slope is always the number multiplied by x.

Answers

Answer:

we have added 9/4 to both sides of the equation.

Step-by-step explanation:

The given equation is :

[tex]x^2+3x=6[/tex]

Here, a = 1, b = 3 and c = 6

We should add (b/2)^2 to the both sides of the equation.

(b/2)^2 = (3/2)^2 = (9/4)

[tex]x^2+3x+\dfrac{9}{4}=6+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{33}{4}\\\\x+\dfrac{3}{2}=\pm \dfrac{\sqrt{33}}{2}\\\\x= +\dfrac{\sqrt{33}}{2}-\dfrac{3}{2}, -\dfrac{\sqrt{33}}{2}-\dfrac{3}{2}\\\\=1.37,-4.37[/tex]

Hence, we have added 9/4 to both sides of the equation.

need to use for particular students)
• Student Worksheet
