∡ZYX= 180°-115°=65°
Since it is a triangle, ∡ZYX + ∡YZX + ∡XZY = 180°
65° + (4k+5)° + (6k+10)° = 180°
10k°+15°=115°
k=10

The value of U.S exports to China increased from $1480 million in 2011 to $2768 million
aliya0001 [1]

The percentage of increase was 87.027... %

<em><u>Explanation</u></em>

The value of U.S exports to China increased from $1480 million to $2768 million.

Suppose, the percentage of increase is  x\%

So, <u>the amount of increase</u> = x\% of 1480 =1480*\frac{x}{100}=14.8x

Thus, the equation will be......

14.8x= 2768-1480\\ \\ 14.8x=1288\\ \\ x= \frac{1288}{14.8}=87.027....

So, the percentage of increase was 87.027... %

Alexander says that 3x + 4y is equivalent to (3)(4) + xy because of any order, any grouping. Is he correct why or why not
snow_lady [41]

Answer:

Alexander is incorrect because the expressions are not equivalent.

Step-by-step explanation:

If the expression is evaluated for any value of x, y; the result will not be same.

For instance, let assume x = 1 and y = 2

3x + 4y = 3 + 4 = 7

(3)(4) + xy = (3)(4) + (1 * 2) = 12 + 2 = 14

So, the expressions are not the same and Alexander is incorrect.
