Answer:

X=-3 y=-8

Step-by-step explanation:

$5x - 6y = 33 \\ y = - 14 - 2x \\$

Put the second one in first

$5x - 6( - 14 - 2x) = 33 \\ 5x + 84 + 12x = 33 \\ 17x = - 51 \\ x = - 3$

$y = - 14 - 2 \times ( - 3) \\ y = - 8$

What multiplication problem is equivalent to 3 3/8 divide by 3/8

Anni [7]

The expression $3\frac{3}{8}\div \frac{3}{8}$ can be written in multiplication problem as: $3\frac{3}{8}\times \frac{8}{3}$ or $\frac{27}{8}\times \frac{8}{3}$

Step-by-step explanation:

We need to find What multiplication problem is equivalent to $3\frac{3}{8}\div \frac{3}{8}$

We are given: $3\frac{3}{8}\div \frac{3}{8}$

Writing it in multiplication problem.

When division sign is changed to multiplication sign, the fraction is reciprocated.

$3\frac{3}{8}\div \frac{3}{8}$

Converting division into multiplication

$3\frac{3}{8}\times \frac{8}{3}$

or we can write as:

$\frac{27}{8}\times \frac{8}{3}$

So, the expression $3\frac{3}{8}\div \frac{3}{8}$ can be written in multiplication problem as: $3\frac{3}{8}\times \frac{8}{3}$ or $\frac{27}{8}\times \frac{8}{3}$

The mean of this data set is 9. What number is missing?<br><br> 11,20,_,3,1

kherson [118]

Let the missing number be x

Mean is the total sum of data over the number of data therefore,

(11+20+x+3+1) / 5 = 9
Then simplify
(35 + x) / 5 = 9
Then multiply 5 to both sides
35 + x = 45
Then subtract 35 to both sides to find x
X= 10

Hope this helps!
