Answer:

9 3/7

Step-by-step explanation:

4 2/7 = 30/7

2 1/5 = 11/5

30/7 x 11/5 = 330/35

Answer:

we can write

42/7 as 30/7

and

21/5 as 11/5

now

$\frac{30}{7} \times \frac{11}{5} \\ = \frac{6}{7} \times 11 \\ = \frac{66}{7}$

we can write 66/7 as 93/7

hence,

option D is correct.

hope this answer helps you dear....take care!

What is the equation of the line that passes through the point (6,14) and is parallel to the line with the following equation? y

Gekata [30.6K]

Answer:

$y=\displaystyle-\frac{4}{3}x+22$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept
Parallel lines always have the same slope (m)

Determine the slope (m):

$y=\displaystyle-\frac{4}{3}x -1$

The slope of the given line is $\displaystyle-\frac{4}{3}$ , since it is in the place of m in y=mx+b. Because parallel lines always have the same slope, the slope of a parallel line would also be $\displaystyle-\frac{4}{3}$ . Plug this into y=mx+b:

$y=\displaystyle-\frac{4}{3}x+b$

Determine the y-intercept (b):

$y=\displaystyle-\frac{4}{3}x+b$

To find the y-intercept, plug in the given point (6,14) and solve for b:

$14=\displaystyle-\frac{4}{3}(6)+b\\\\14=-8+b\\b=22$

Therefore, the y-intercept of the line is 22. Plug this back into $y=\displaystyle-\frac{4}{3}x+b$ :

$y=\displaystyle-\frac{4}{3}x+22$

I hope this helps!

There are 132 people seated in the school auditorium for an assembly. There are 6 rows in the auditorium, each with the same nu

Damm [24]

You do 132 ÷ 6 which is 22, so that is the answer. This is because if you the auditorium is filled, then there are a total of 132 seats. If there are 6 rows, then there have to be 22 seats each row to make 132 seats. I hope this helps!
