If x increased by the product of 11 and y is 103, and 9x increased by the product of 10 and y is 126, what are the values of x and y?
A. x= 8y=5
B. x = 9.y = 12
C. X= 4, y = 9
D. x = 9, y = 4

C. x=4,y=9

Step-by-step explanation:

The given information show that

x+11y=103 (1)

9x+10y=126 (2)

Isolate x from (1)

x=103-11y

Substitute x=103-11y into (2)

9(103-11y)+10y=126

927-99y+10y=126

-89y=-801

y=9

So x=103-11x9=4

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..
