Fine lowest common values for x and y variables of A[4x - 7y = 2] B[3x - 3y = 6]

Mathematics

OLEGan [10]3 years ago

3x -3y = 6

or, 3(x -y)= 6

or, x-y =6/3

or, x-y = 2

or, x=2+y........eqn(i)

4x - 7y = 2

substituting the value of x from eqn(i)

or, 4(2+y) -7y = 2

or, 8 + 4y -7y = 2

or, -3y = 2-8

or, y = -6/-3

■ y=2

so in eqn(i)

x= 2+y

x= 2+2

■x = 4

Answer:

1. The right triangles pass the AA similarity congruence theorem.

2. s/q

Step-by-step explanation:

They are similar since they pass the AA( Angle-Angle) similarity theorem.

Similar triangles have corresponding proportional sides so side z corresponds with side s and side x corresponds with q so we would represent that as

s/q

How do you work this out
oksian1 [2.3K]

Answer:

Below.

Step-by-step explanation:

To find the number of students in each grade you multiply the marks by the frequency density. The number of students is given by the area under the  rectangles.

So to find the number of students with grade U (< 160)  it is:

120 * 0.2 + 40*0.5

= 24 + 20

= 44.

The number for Grade E

= (200 - 160) * 0.5

= 40 * 0.5

= 20.

The others can be found in the same way.
