Answer:

7 1/7

Step-by-step explanation:

For the problem:

5 /7 × 10 = ?

Convert any mixed numbers to fractions:

10 = 10

Multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

5 × 10

7 × 1

50 /7

50 ÷ 7 = 7R1, therefore:

50 /7 = 7 1/7

The result is:

× 10 = 7 1/7

Answer:

$y = - \frac{1}{4} x - 10$

Step-by-step explanation:

The negative reciprocal of 4 is -1/4.

Let's substitute in our values, to find the y-intercept:

$y = - \frac{1}{4} x + c$

$- 11 = - 1 + c$

$c = - 10$

Finally, our full equation is:

$y = - \frac{1}{4} x - 10$

What is the missing angle measure?

Evgen [1.6K]

Answer:

x = 33

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180 for x

x = 180 - (90 + 57) = 180 - 147 = 33
