Answer:
-9 = 0.45m
Step-by-step explanation:
0.45m -9 = 0.9m
-0.45m -0.45m
-9 = 0.45m
Answer:
528 miles
Step-by-step explanation:
The unit of miles per gallon is 33
Use the 396/12 to find that
To find how much for 16 gallons multiply 16 by 33
16*33 = 528
On 16 gallons she can drive 528 miles
Answer: z= - b+17/a+4
Step-by-step explanation:
I think it would be logical if the given information are the dimensions of the water container which should be 200 cm × 633 cm. Supposing the water container is in the shape of the rectangle, the area would just be the product of the dimensions. Convert cm first to m to be consistent with units. (100 cm = 1 m)
Area = (200 cm * 1 m/100 cm)(633 cm * 1m/100 cm)
Area = 12.66 m²
Answer: the length of the sides are 21m, 16m and 28 feet
Step-by-step explanation:
Let x represent the length of the first side.
Let y represent the length of the second side.
Let z represent the length of the third side.
The perimeter of a triangle is 65 meters. It means that
x + y + z = 65- - - - - - - - - - 1
The second side is 5 meters less than the first side. It means that
y = x - 5
The third side is 7 meters more than the first side. This means that
z = x + 7
Substituting y = x - 5 and z = x + 7 into equation 1, it becomes
x + x - 5 + x + 7 = 65
3x + 2 = 65
3x = 65 - 2 = 63
x = 63/3
x = 21
y = 21 - 5 = 16
z = 21 + 7 = 28
