Answer:
-7 and 21
Step-by-step explanation:
y-2y=7 (sub x=7 to the equation)
-y=7
y=-7 (not sure of its correct)
if y=-7,
x-2(-7)=7 (sub y=-7 into equation)
x-14=7
X=7+14
X=21

Answer: " b = 3 ⅕ ; or, write as: 3.2 .
_____________________________________
Given: "A = (1/2) * b * h " ;
↔ A = (b * h) / 2
2A = (b*h) ;
2A/ h = b ;
↔ b = (2A) / h ;
Given A = 48 ; and h = 30 ; Plug in these values; and solve for "b" ;
→ b = (2*48) / 30 ;
= 96/30 ;
= (96÷6) / (30÷6) ;
→ b = 16/5 ; = 3 <span>⅕ ; or, write as: 3.2 .
