Answer:
[1, ∞)
Step-by-step explanation:
To solve a compound inequality, first separate it into two inequalities and solve them separately:
Solution of Inequality 1:
x + 7 ≥ 4
⇒ x ≥ 4 - 7
⇒ x ≥ -3
Solution of Inequality 2:
11x - 8 ≥ 3
⇒ 11x ≥ 3 + 8
⇒ 11x ≥ 11
⇒ x ≥ 1
As both graphs overlap for x ≥ 1, this is the solution.
Therefore, in interval notation: [1, ∞)
Answer:
Leo is 1 year old.
Step-by-step explanation:
Given:
Lily's age = 5
Leo's age =
we need to find the Leo's age.
Solution:
Leo's age =
where x ⇒ Lilly age
But Lilly's age = 5 years (given)
So we will substitute the value of x as 2 in Leo's age expression.
On Substituting we get;
Leo's age =
Hence Leo is 1 year old.
Answer:
$147.25
Step-by-step explanation:
The hat shop wants to markup the hat that they bought for $95 by 55%.
This means that they want to increase the price by 1.55 of 95.
Multiply 95 by 1.55 to calculate the 55% increase of the hat.
The selling price of the hat should be $147.25.
The answer is B the second one
