Ella and Ola had 70 mushrooms altogether. 5/9 of Ella's mushrooms are brown and 2/17 of Ola's mushrooms are white. How many mushrooms did Ella have?

45 mushrooms

Step-by-step explanation:

Ella and Ola had 70 mushrooms altogether. 5/9 of Ella's mushrooms are brown and 2/17 of Ola's mushrooms are white. How many mushrooms did Ella have?

Let the amount of Ella's mushrooms be x

Let the amount of Ola's mushrooms be y

If Ella and Ola had 70 mushrooms altogether, then;

x + y = 70

5/9 x = brown

2/17 y = white

Substiute

x + 5/9 x = 70

14 x/9 = 70

14x = 9 * 70

x = 9* 5

x = 45

Hence Ella has 45 mushrooms

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

ab will be equal to
