If you multiply me by 7, add 2 and divide by 3. You get 10. What number am I?​

Answers

Answer 1

Answer:

4

Step-by-step explanation:

4 times 7 = 28

28 + 2 = 30

30/3 = 10

Answer 2

Answer:

4

Step-by-step explanation:

In numerical terms, write down what the problem says to,

( 7x + 2 ) ÷ 3 = 10

Now solve with inverse operations and simplification,

( 7x + 2 ) ÷ 3 = 10

              *3     *3

7x + 2 = 30

     -2    -2

7x = 28

÷7     ÷7

x = 4

write an equation for the line that passes through (-4,1) and (-8,6)

Answers

Answer:

[tex]y=- \frac{5}{4}x-4[/tex]

Step-by-step explanation:

1) if the A has coordinates (-4;1) and B - (-8;6), then it is possible to write the formula of the required line:

[tex]\frac{X-X_A}{X_A-X_B} =\frac{Y-Y_A}{Y_B-Y_A};[/tex]

2) if to substitute the coordinates given in the condition, then:

[tex]\frac{X+4}{-8+4} =\frac{Y-1}{6-1};[/tex]

3) finally, the required equation of the line is:

-4y=5x+16; ⇔y= -5/4 x-4 (slope-intersection form)

Oh okie oh yeah yeah lol lol
The mark up is 31.5%
Because $22.95 is 31.5% more than $17.45
I saw that the difference between the numbers was roughly a third so I timed 17.45 by .30 to get the percentage then added it back to itself and it was almost right then I upped it and got the right number.

Faris' arrival time = 3:30 pm + 3 h 54 mnt = 7:24 pm
Step-by-step explanation:
Driving distance between Manchester to London = 195 miles
Coach left Manchester = 3.30 pm
Average speed of coach = 50 mph
Total time taken by the coach to reach the Manchester to London = 195÷50 = 3.9 h
0.9 h = 0.9×60 mnt = 54 mnt
Now,
3.9 h = 3 h 54 mnt
Hence Faris' arrival time in London = 3.30 pm + 3 h 54 mnt = 7.24 pm

Step-by-step explanation:

complementary angles means that both of them together = 90

13y +12 + 20y + 12 = 90

add all y together and numbers together
