X= miles driven in April


(253 + 277 + 280 + x)/4= 284
add in parentheses

(810 + x)/4= 284
multiply both sides by 4

810 + x= 1136
subtract 810 from both sides

x= 326 miles


ANSWER: She must drive 326 miles in April to average at least 284 miles January through April.

Hope this helps! :)

Factor completely, then place the answer in the proper location on the grid. <br> 6х^2 - 3х - 30
Tems11 [23]

Answer:

3(x + 2)(2x - 5)

Step-by-step explanation:

Given

6x² - 3x - 30 ← factor out 3 from each term

= 3(2x² - x - 10) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 10 = - 20 and sum = - 1

The factors are + 4 and - 5

Use these factors to split the x- term

2x² + 4x - 5x - 10 ( factor the first/second and third/fourth terms )

= 2x(x + 2) - 5(x + 2) ← factor out (x + 2) from each term

= (x + 2)(2x - 5), thus

2x² - x - 10 = (x + 2)(2x - 5) and

6x² - 3x - 30

= 3(x + 2)(2x - 5) ← in factored form

How would i do this and whats the answer
cricket20 [7]

Answer:

Since we can see that they are vertically opposite angles

so 33° = 2x +1°

2x =33°+1°

2x = 34°

Therefore x= 17°
