-2.85

Step-by-step explanation:

To convert 22/20 into a decimal, we must multiply it by 5 to get a denominator of 100.

5(22/20)= 110/100= 1.10

So now lets solve the equation.

-1.75-1.10 = -2.85

-1.75 -22/20

make -1.75 and -22/20 into a mixed fraction

-1 75/= -1 75/100 ( divide by 5 for the numerator and denominator)

75/5=15

100/5=20

Divide 15 and 20 again ( reducing)= 15/5=3, 20/5=4

-22/20=-2 2/20 ( divide by 2 for 2/20)= 2/2=1, 20/2=10

-1 3/4- 1 1/10

find the common denominator for the fractions which is 20

Multiply by 5 for -1 3/4

3(5)/4(5)=15/20= -1 15/20

Multiply by 2 for -1 1/10

1(2)/10(2)=-1 2/20

-1 15/20-1 2/20=-2 17/20 or in decimal : -2.85

-2 17/20 or -2.85

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
