Bring it to the form ax + by = c, where a is positive, and there are no fractions in the equation.
Here, we need to add 2/5x to both sides:
2/5x + y = 0
Then multiply everything by 5 to get rid of the fraction
2x + 5y = 0 <==
Step-by-step explanation:
2y+9= 4
2y=-5
y=-5/2
y= -2and 1/2
Given:
1 m : 25 cm
8 in : 1 ft
12 in : 1 ft
First, we convert each
variable given on the right:
1 m : 0.25 m (this means that
1 meter is made to represent 25 cm)
8 in : 12 feet (this means
that 8 in is made to represent 1 feet)
12 in : 12 in (this means
that 12 in is made to represent 1 feet)
<span>After converting the
variables, we can now know if the ratios are enlargement, reduction or
preservation. Therefore:
1 m : 25 cm = Enlarge</span>
<span>8 in : 12 feet = Reduce
12 in = 1 ft = Preserve</span>
Answer:
yes
Step-by-step explanation:
For the given sides to make a triangle.
The sum of any 2 sides must be greater than the third side
10 + 7 = 17 > 11
10 + 11 = 21 > 7
7 + 11 = 18 > 10
Thus the sides 10, 7, 11 will make a triangle
