6x – 2y = 10 2x + 3y = 51 solving the first equation above for y gives:

1 answer:

6 0

The first equation is 6x - 2y = 10. To solve for y, you will use inverse (opposite) operations to undo what is happening to y. Please see the steps below for the work.

6x - 2y = 10
-6x -6x
<u>-2y </u>= <u>(-6x + 10)</u>
-2 -2
y = 3x - 5

Answer:

-11/20

Step-by-step explanation:

2 8 1

(0-— ÷ (0-—))+—

3 9 5

Simplify —

8/9

2 8 1

(0 - — ÷ (0 - —)) + —

3 9 5

Simplify —

2/3

2 -8 1

(0 - — ÷ ——) + —

3 9 5

2 -8

Divide — by ——

3 9

To divide fractions, write the divison as multiplication by the reciprocal of the divisor :

2 -8 2 9

— ÷ —— = — • ——

3 9 3 -8

(0--3/4)+1/5

Least Common Multiple:

Left_M = L.C.M / L_Deno = 5

Right_M = L.C.M / R_Deno = 4

3 • 5 + 4 -11

ASHA 777 [7]

Answer:

$x=10$

Step-by-step explanation:

Notice that all three sides of the given triangle has one tick mark.

This means that all three sides are congruent, meaning that we have an equilateral triangle.

And for equilateral triangles, all three angles are also congruent.

So:

$\angle CBA=\angle BAC=\angle ACB$

Also, recall that the interior angles of a triangle is always 180. Thus:

$\angle CBA+\angle BAC+\angle ACB=180$

Substitute:

$\angle CBA+\angle CBA+\angle CBA=180$

Combine like terms:

$3\angle CBA=180$

Substitute:

$3(6x)=180$

Multiply:

$18x=180$

Thus:

$x=10$

And we are done!
