<h2>Решение (а):</h2>
Чтобы найти значение x, воспользуемся перекрестным умножением.
Что значит ,
= 2 × 30 = 5 × х
= 2 × 30 = 5x
= 60 = 5x
= х = 60 ÷ 5
= х = 12
Следовательно, 2/5 = 12/30.
<h2> Решение (б):</h2>
Чтобы найти значение x, воспользуемся перекрестным умножением.
Что значит ,
= 30 × 8 = 48 × х
= 30 × 8 = 48x
= 240 = 48x
= х = 240 ÷ 48
= х = 5
Следовательно, 5/8 = 30/48 .
Answer:
Step-by-step explanation:
Solutions are intersection points, basically they are the values that satisfy both equations which happen to be the points in common or interseciton points
we see that the line intersects the circle in 2 places
2 solutions
A
Answer:
angle 1 = angle 2
Step-by-step explanation:
1 and 2 are corresponding angles meaning if they are equal but on opposite sides. If you now for example angle 1 = 20 , 2= is also 20. This is helpful to know if you want to solve for x on one of these angles
