Answer:

The answer is 45

Step-by-step explanation:

The equation is a straightforward one, we have:

2/3x = 30

because we have a fraction on at least one side, we will cross multiply thus:

2x = 30 x 3

2x = 90

Next, we divide both sides by 2 to make x the subject of the formula, we have 2x/2 = 90/2

x = 45

Therefore, it takes Ingrid 45 minutes to complete her essay

Lara has three cats: Socks, Princess, and Luna. The ratio of Sock's weight to Princess's weight is 4:5. The ratio of Princess's
romanna [79]
A = Sock's weight
b = Princess' weight
c = Luna's weight

a : b = 4 : 5
b : c = 6 : 7

at this point, we have to change the 2 ratios (a : b and b : c) into one ratio (a : b : c)
to do that, we have to change the ratio number so the number b in both ratio is the same

a : b = 4 : 5 = 24 : 30
b : c = 6 : 7 = 30 : 35
From that we can conclude that
a : b : c = 24 : 30 : 35

Since we're looking for the ratio of Sock's weight to Luna's weight, it will be
a : c = 24 : 35
