Answer:

2x-1 = 5x-14

Step-by-step explanation:

5(2x−1) = 5(5x−14)

Divide each side by 5

5/5(2x−1) = 5/5(5x−14)

2x-1 = 5x-14

Jason a 4 lengths of rope. The lengths are 3 inches, 15 centimeters, 0.3 meters, and 0.5 feet. About how much rope does Jason ha

AnnZ [28]

Answer: 67.5 cm

Step-by-step explanation:

Jason has 4 lengths of ropes

first is $3\ in.\approx 7.5\ cm$

second is $15\ cm$

Third is $0.3\ m\approx 30\ cm\quad [\text{1 m = 100 cm}]$

fourth is $0.5\ ft\approx 6\ in.\approx 15\ cm\quad [\text{1 ft=12 in.}]$

the total length of rope is the sum of four lengths

$\Rightarrow 7.5+15+30+15=67.5\ cm$

Solve the inequality −14a≥42, and write the solution in interval notation.

PSYCHO15rus [73]

The solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.

<h3>What is inequality?</h3>

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have an inequality:

−14a ≥ 42

-a ≥ 3

a ≤ -3

a ∈ (-∞, -3]

Thus, the solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.

Write one digit on each side of 10 to make a four digit multiple of 72. How many different solutions does this problem have? The

Viefleur [7K]

If we write 4 to each side of 10, we will get a four digit number 4104, which is a multiple of 72.

To find out other possible solutions, first start with 1 in front of 10.

Now, divide 110 by 72.

The remainder is 38.

We are going to put one more digit after 10.

So, let us check if there is any three digit number whose first two digits are 38 and which is a multiple of 72.

There is no such number since 5 × 72 = 360 and 6 × 72 = 432.

So, there is no four digit number whose first three digits are 110 and which is a multiple of 72.

If we try like this, we can find 4104 is the only solution.
