Step-by-step explanation: Hope this helps :)
Sarah is selling bracelets. The inequalities are a > 10 and 2a + 3b ≥ 60.
<u>Solution:</u>
Given, Sarah is selling bracelets and earrings to make money for summer vacation.
bracelets cost = $2
earrings cost = $3
She needs to make at least $60.
Sarah knows she will sell more than 10 bracelets.
We have to write inequalities
Now, according to given information,
Total money ≥ $ 60
Money earned from bracelets + money earned by earrings ≥ 60
2 x number of bracelets + 3 x number of earrings ≥ 60
2a + 3b ≥ 60
[ where a is number of bracelets and b is number of earrings]
And, number of bracelets is more than 10 ⇒ a > 10
Hence, the inequalities are a > 10 and 2a + 3b ≥ 60
Answer:
D: x + (x+1) + (x+2) > 60
Step-by-step explanation:
Let
x = youngest brother age
x + 1 = older brother age
x + 2 = oldest brother age
Fathers age = 60
The inequality is
x + (x+1) + (x+2) > 60
x + x + 1 + x + 2 > 60
3x + 3 > 60
3x > 60 - 3
3x > 57
x > 57/3
x > 19
x + 1
19 + 1
20
x + 2
19 + 2
21
The oldest brother is no younger than 21
The youngest brother is no younger than 19
The oldest brother is 2 years older than the youngest brother since each are one year apart.
If 45=15h then h must be 3
