Step-by-step explanation:

$4(5x - 2) = 2(9x + 3) \\ 20x - 8 = 18x + 6 \\ 20x - 18x = 8 + 6 \\ 2x = 14 \\ \frac{2x}{2} = \frac{14}{2} \\ x = 7$

Answer:

Step-by-step explanation:

4(5x-2) = 2(9x+3)

The value of x can be obtained as follow:

Clear the bracket

20x - 8 = 18x + 6

Collect like terms

20x - 18x = 6 + 8

2x = 14

Divide both side by the coefficient of x i.e 2

x = 14/2

x = 7

Therefore, the value of x is 7

Answer:

Step-by-step explanation:

ok, without reading through any of the answers lets see what we can get just from looking at that picture.

We can see that the angles being bisected are on a straight line.

A straight line is 180 degrees.

We know that you have to add both angles together to get 180.

The answer has to equal 180.

A is the only option that offers that.

Select the values that make the inequality h < 2 true.

weqwewe [10]

Given:

The inequality is:

$h\leq 2$

To find:

The values that make the given inequality true.

Solution:

We have,

$h\leq 2$

It means the value of h must be less than or equal to 2.

In the given options, the list of numbers which are less than or equal to 2 is

-6, -3, -1, 1, 1.9, 1.99, 1.999, 2

The list of numbers which are greater than 2 is

2.001, 2.01, 2.1, 3, 5, 7, 10

Therefore, the first 8 options are correct and the required values are -6, -3, -1, 1, 1.9, 1.99, 1.999, 2.

Amy ran 8 miles. She recorded how long it took her to run each mile, rounded to the nearest 1/4 of a minute. How long did it tak

soldi70 [24.7K]

Answer: 16 minutes.

Step-by-step explanation:

Given that the:

Distance covered = 8 miles

And it took her to run each mile, rounded to the nearest 1/4 of a minute.

Since it is a minute ( 1 minute ), add 0.25 to 1 for the fastest and subtract 0.25 from 1 for the slowest.

That is, 1 + 0.25 = 1.25 for maximum time, and 1 - 0.25 = 0.75 for the minimum.

For the Army slowest , 8 × 0.75 = 6 minutes

For the Army fastest, 8 × 1.25 = 10

Amy runs her slowest and fastest mile combined by adding the value of the slowest to the value of the fastest.

10 + 6 = 16 minutes
