Answer:
50. ☺️☺️
Step-by-step explanation:
I'm going to assume you need this inequality solved.
First, write it as numbers, not words.
7/10n + 14 < 49
where "n" is the unknown number.
Second, if I were you, I'd change that fraction into a decimal, as it'll make life easier later on.
7/10 = 0.7
Now, solve it like you would any other equation.
0.7n + 14 < 49
0.7n +14 - 14 < 49 - 14
0.7n < 35
0.7n ÷ 0.7 < 35 ÷ 0.7
n < 50
The answer is n < 50
I'm sorry but I'm not into square roots yet :(
38 + 4 = 42 (1 year); 42 + 4 = 46 (2 years); 46 + 4 = 50 (3 years); 50 + 4 = 54 (4 years); 54 + 4 = 58 (5 years)
45.5 + 2.5 = 48 (1 year); 48 + 2.5 = 50.5 (2 years); 50.5 + 2.5 = 53 (3 years); 53 + 2.5 = 55.5 (4 years); 55.5 + 2.5 = 58 (5 years)
It will take 5 years before the trees are the same height, 58 inches.
It can be deciamls, fractions etc
Answer:
Jeremy's house is 4.5 inches far from his friend's house on the map
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The house of Jeremy's friend is 72 miles away from his home
∴ The actual distance between the two houses is 72 miles
∵ The scale on Jeremy's map is 
inch is equivalent to 8 miles
∴ Each miles on the map represents actual distance 8 miles
By using the ratio method
→ Map length : Actual length
→ inch : miles
→ : 8
→ x : 72
By using cross multiplication
∵ x × 8 = × 72
∴ 8 x = 36
- Divide both sides by 8
∴ x = 4.5
x represent the distance between the two houses on the map
Jeremy's house is 4.5 inches far from his friend's house on the map
