angle1 = 4y - 9°
angle2 = 40°
angle3 = 5y°
Angle sum property
180° = angle1 + angle2 + angle3
Therefore,
180 = (4y - 9) + 40 + 5y
180 = 4y - 9 + 40 + 5y
180 = 9y + 31
180 - 31 = 9y
149 = 9y
149/9 = y
12/x + 7 =13/x, where x is not 0;
<=> 12 + 7x = 13 <=> 7x = 1 <=> x = 1/7;
Answer:
The answer is 4×4+5×2−3.
Step-by-step explanation:
This is because, in the original amount, they had 4 tanks with 4 fish and 5 tanks with 2 fish. 4x4 is 16 and 5x2 is 10. Then you add them together to get 26. But, you have to subtract 3 because of the order of 3 fish, which equals 23. The equation 4×4+5×2−3 shows that.
