Answer:
x = √76
Step-by-step explanation:
in upper triangle :
7² - 3² =40 so the third side of the upper triangle is : √40
in the biggest triangle :
(3+3)² + 40 = 76 so the another side of the biggest triangle is : √76
To solve it you have to distribute (multiply) the 4 to the x and the 2.Then you would have to subtract 8 by both sides and which it would cancel on the left side, then after you divide 4 by both sides and then u get you answer.
Answer:
The answer to your question is the letter D. 30 pounds
Step-by-step explanation:
Data
increase = 50%
final weighed = 45 pounds
Process
1.- Use proportions to solve this problem. 45 pounds will be 150% (the initial 100% plus an increase of 50%).
45 pounds ------------------ 150%
x pounds ----------------- 100%
x = (100 x 45)/150
x = 4500/150
Result
x = 30 pounds
