Answer:

x= 1 y= 3

Step-by-step explanation:

y= 2x+1

y= 4x-1

4x-1=2x +1

4x-2x= 1+1

2x=2

x=2/2

x=1. replace x=1 in any of the equation to find y

y= 2(1)+1

y= 2+1

y=3

What is the missing length? 10.2 cm a area=51 cm2

AleksAgata [21]

Answer:

a = 10 cm

Step-by-step explanation:

Area of triangle, A = 51 cm²

base, b = 10.2 cm

Let height of triangle be a cm

Formula:-

$A=\dfrac{1}{2}\times a\times b$

$51=\dfrac{1}{2}\times a\times 10.2$

$a=\dfrac{51\times 2}{10.2}$

$a=10$

hence, the missing length is 10 cm
