Solve the system using any method.
y = 3x + 2
y = 7x - 10

Answers

Answer 1

Answer:

Answer:

x=3

y=11

Step-by-step explanation:

y = 3x + 2 equation 1

y = 7x - 10 equation 2

using equation 1 in equation 2 we have:

3x + 2 = 7x - 10

2=7x - 3x -10

2 = 4x -10

2+10 = 4x

12= 4x

12/4 = x

we have:

x= 3

using equation 1:

y = 3x + 2

y= 3(3)+2

y=9+2

y=11

What is 22% expressed as a fraction in simplest form?

Answers

22% when expressed as a fraction is 22/100.
to write this in the simplest form, we have to keep dividing both numerator and denominator by a common number.
22/100 , both are divisible by 2. therefore when 22/100 is divided by 2
$(22/2)/(100/2) = (11)/(50)$
then we get 11/50. this cannot be divided any further by a common factor to both. therefore simplest form is 11/50

11/50 is 22% expressed as a fraction in simplest form.

Here, we have,

22% when expressed as a fraction is 22/100.

to write this in the simplest form, we have to keep dividing both numerator and denominator by a common number.

22/100 ,

both are divisible by 2.

therefore when 22/100 is divided by 2

we get,

22/2 / 100/2

=11/50

then we get 11/50.

this cannot be divided any further by a common factor to both.
