9 ÷ 3[(20 − 7) − 22]

Mathematics

Answer:

-27

Step-by-step explanation:

Any operations inside parentheses must be carried out first.

Thus,

9 ÷ 3[(20 − 7) − 22] becomes 9 ÷ 3[(13) − 22]

This, in turn, becomes 9 ÷ 3[-9].

The negative operator can be taken out and written up front:  -9 ÷ 3[9) Note:  this does not call for subtraction).

Carrying out the indicated operations from left to right:

-3(9) = -27

Fynjy0 [20]

Answer:

y = 3x - 11      

Step-by-step explanation:

Step 1:

y = mx + b          Slope Intercept Form

Step 2:

y = 3x + b        Input Slope

Step 3:

- 5 = 3 ( 2 ) + b        Input x and y values

Step 4:

- 5 = 6 + b          Multiply

Step 5:

- 11 = b        Subtract 6 on both sides

Answer:

y = 3x - 11      

Hope This Helps :)

Ilia_Sergeevich [38]

Answer:

(b) She should have rounded –8.02 to –8

Step-by-step explanation:

Given

See attachment for long division

Required

Her error

Ignoring the minus sign,

Her approximation is as follows:

-71.81 \approx 72

-8.02 \approx 9

Her approximation of -8.02 is wrong

Because:

-8.02 \approx 8

<em>Hence (b) is correct</em>
