HELP ASAP PLEASE !!!

Parallel Line and Irlangte
What is the value of x?
Enter your answer in the box.

Answer:

x = 18

Step-by-step explanation:

Given

[tex]\frac{3x}{5}[/tex] + 1 = [tex]\frac{4x}{15}[/tex] + 7 ( subtract 1 from both sides )

[tex]\frac{3x}{5}[/tex] = [tex]\frac{4x}{15}[/tex] + 6

Multiply through by 15 to clear the fractions

9x = 4x + 90 ( subtract 4x from both sides )

5x = 90 ( divide both sides by 5 )

x = 18

Answer:

6.66 hours, that is, 6 hours and 40 minutes.

Step-by-step explanation:

If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.

If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.

So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:

(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66

So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.

This is a conditional: if the condition A is satisfied (true), then the result B is also satisfied (true).

Answer:

Its conditional , as the A decides what B has to do , whether this or that

Answer:

19b-4

Step-by-step explanation:

7b+3(4b-2)+6÷3

Bracket comes first so we distribute 3 over the terms in the bracket

= 7b + 12b -6 +6 ÷ 3

First we solve division

= 7b + 12b -6 +6 ÷ 3

= 7b + 12b -6 +2

= (7b+12b)+(-6+2)

= 19b -4

This can't be simplified further as it can't be solved anymore

Answer:

19b - 4

Step-by-step explanation:

Distribute the 3 to (4b - 2), like so:

3(4b - 2)

12b - 6

→ 7b + 12b - 6 +6 ÷ 3

Add like terms:

→19b - 6 + 6 ÷ 3

Following PEMDAS, you divide 6 by 3 first:

→19b - 6 + 2

Add like terms:

→19b - 4

Answer:

15/20 and 18/20

Step-by-step explanation:

Least common denomintor of 3/4 and 9/10 = least common multiple of 4 and 10

multiples of 4: 4, 8, 12, 16, 20

multiples of 10: 10, 20

Least common denominator = 20

Rewrite fractions: 15/20 and 18/20

3/4 and 9/10 using the least common denominator is 15/20 and 18/20.

LCM of two or more than two given numbers is the smallest common multiple that is divisible by two or more than two given numbers.

Given, are two fractions 3/4 and 9/10 we know the LCM of 4 and 10 is 20.

∴ (3×5)/(4×5) and (9×2)/(10×2).     (we have to multiply same constant to the  

                                                         fraction to retain it's original value).

So,  3/4 and 9/10 using the least common denominator is 15/20 and 18/20.

Answer:

The slope decreases and the y-intercept decreases.

Explanation:

Red is original, blue is when y is doubled.

Answer:

Given below

Step-by-step explanation:

M is Mikey and B is Betty in,

Current ages:

M= x

B= 3x (cuz she is 3 times older)

After 5 years

M= x+5

B= 3x+5 (5 years added to present age)

It says the ages of Betty after 5 years (3x+5) will be twice as much as Mikey (2(X+5))

So,

3x+5 = 2(x+5)

3x+5 = 2x+10

3x -2x = 10-5

x = 5

Therefore,

The current ages are

Betty : 3x = 3*5 = 15

Mikey: 5 (x)

You can verify by checking with the criterias or clues given in the question.. hope this helps..mark as brainiest if this was helpful:)

Answer: It means that there are 570 chocolate chips in all the 30 cookies

Step-by-step explanation:

The mean also referred to as the average of a data set is calculated by adding all numbers in a data set and dividing by number of values in the set.

Since the mean number of chocolate chips in 30 cookies is 19 chocolate chips, this means that there are:

= (30 × 19) = 570 chocolate chips in the cookies.

Answer 37  

Answer: 36

The LCM of 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 is 2 × 3 × 2 × 5 × 7 × 2 × 3 × 11 = 27720.

A multiple of 27720 will end in 0, and the sum of its digits will be a multiple of 9.

The largest 6-digit number which is multiple of 9 with last digit of 0 is 999990, and the sum of its digits is 45. 45 is not a multiple of 27720, and there is no other way to get a digit sum of 45.

We now look at the next biggest multiple of 9, 9 × 4

= 36.

The largest 6-digit multiple of 27720 is 27720 × 36 = 997920, and the sum of its digits is 36.
