Answer:
x = -3
Step-by-step explanation:
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 1.4 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
0.7x - 1.4 = -3.5
→ First multiply everything by 10 to make everything into a whole number
7x - 14 = -35
→ Plus 14 to both sides to isolate 7x
7x = -21
→ Divide both sides by 7 to isolate 7
x = -3
Answer:
87.5
Step-by-step explanation:
Answer: it is 1/6
You can solve by saying, 1 out of 6 in each tray is red, so my fraction should be 1/6.
It doesn't matter the amount of trays because the pattern is always the same.
But if you want to check it out you can do it in this way.
You know there is 1 red color per tray, if there are 20 then you'd have 20 of them, in each tray there are 6 colors so the total is 120.
Now you solve it if there are 20 red colors out of 120 them the answer is 20/120, thus you get 1/6
Step-by-step explanation:
Fruit : yoghurt : total
2 : 3 : 2 + 3
2 : 3 : 5
5 parts = 185
1 part = 185 ÷ 5 = 37
3 parts = 37 x 3 = 111g
The mass of the yoghurt is 111g
