Answer: 4 is 110 degrees and 3 and 1 is 70 degrees.
Step-by-step explanation: 4 is equal to 2 so 4 is 110 degrees 4
110 x 2 = 220 360 - 220 = 140/2 = 70 so 3 and 1 = 70 degrees
{-2x + 7y = -5
{-2x - 4y = 6 | · (-1)
{-2x + 7y = -5
{2x + 4y = -6 (+)
----------------------------------
-2x + 2x + 7y + 4y = -5 + (-6)
11y = -11 | : 11
y = -1
{y = -1
{2x + 4y = -6
{y = -1
{2x + 4 · (-1) = -6
{y = -1
{2x - 4 = -6 | + 4
{y = -1
{2x = -2 | : 2
{y = -1
{x = -1
Answer: the answer is 3
Step-by-step explanation:
An increase of 100% in the value of (rh) means the value doubles. When that doubled value is squared, the new area is 4 times the old area.The question asks how many times GREATER the new A is than the old A. 4 times AS LARGE AS is a 300% INCREASE, which is 3 TIMES LARGER THAN.So the grammatically correct answer is 3
