CROSS MULTIPLICATION my friend
Sorry accidentally pressed answer instead of space down
Cross multiplication is multiplying across the = sign by the denominator and numerator. For example, 10/5=3/x
So we multiply across the = sign, giving us that 10x=15
It is much easier to solve from there; divide by 10 on both sides and x=1.5

3/x=4/20
Same principle applies:
60=4x
÷ by 4 (the coefficient of x)
x=15

2/x=6/10
20=6x
x=20/6 - - > 10/3

8/x=4/11
88=4x
x=22

Y=6x-11<br> -2x-3y=-7 gnjjj
KiRa [710]

Answer:

x=2 y=1

Step-by-step explanation:

Solve the equations by substituting y=6x-11 into -2x-3y=-7.

-2x-3(6x-11)=-7

-2x-18x+33=-7

-20x+33=-7

-20x=-7-33

-20x=-40

x=2

To find y, substitute this value into the equation and solve for y.

y=6(2)-11

y=12-11

y=1

1) Find the values of 'a' and 'b' for the given parallelogram *
nataly862011 [7]

Answer:

first option

Step-by-step explanation:

In a parallelogram consecutive angle are supplementary, sum to 180, so

2a + 122 = 180 ( subtract 122 from both sides )

2a = 58 ( divide both sides by 2 )

a = 29

---------------

In a parallelogram the opposite sides are congruent, then

b + 6 = 10 ( subtract 6 from both sides )

b = 4
