The strategy is called expanding notation because you are expanding that problem into small equations :)
Answer:
y=6
x=6.42
Step-by-step explanation:
7(-9)+9y=-9
-63+9y=-9
+63 +63
9y/9=54/9
y=6
7x-9(6)=-9
7x-54=-9
+54 +54
7x/7=45/7
x=6.42
Answer:
A. -12 meters
B. 28 meters
C. 40 meters
Step-by-step explanation:
The surface of the ocean would be 0.
Taking this into account, 12 meters below would be 0 - 12, which is -12. Therefore A's elevation would be -12.
For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.
Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.
Answer:
Step-by-step explanation:
To find the length of the pole, use Pythagorean theorem,
4.6m = 4.6*100 = 460 cm
hypotenuse² = base² + altitude²
altitude² = hypotenuse² - base²
=460² - 280²
= 211600 - 78400
= 133200
altitude = √133200 = 364.97 cm
Length of the pole = 364.97 cm
b) Length of stair² = 95² + 364*94²
= 9025 + 133200
= 142225
Length of stair= √14225 = 377.13
Length of stair = 377.13 cm
