Pls Help, 20 points!

skelet666 [1.2K]

Answer:

90/13, 45/13

Step-by-step explanation:

$- 2 = x \\ 7x + 9y = - 45 \\ \\ 7 \times ( - 2)y + 9y = - 45 \\ y = 9 \\ \\ 7x + 9 \times 9 = - 45 \\ x = - 18 \\ (x.y) = (- 18.9) \\ \\$

Simplify:

$- 2 \times 9 = - 18 \\ 7 \times ( - 18) + 9 \times 9 = - 45 \\ - 18 = - 18 \\ - 45 = - 45$

The area of a triangle is 80cm² and its base is 8cm. If its height is (6+k) cm, find the value if k.

Leviafan [203]

Answer:

K=14

Step-by-step explanation:

A=1/2*b*h

80=1/2*8*(6+k) multiply by 2 on both sides

160=8*(6+k) distribute by 8

160=48+8k subtract 48 from both sides

112=8k divide by 8

14=K
