Answer:
h ≤ 8
Step-by-step explanation:
Hans charges $7 per hour and pays $5 in equipment fees.
$5 is fixed in this case. Let the possible number of hours be h.
According to question,
Atleast means less than equal to. So,
7h-5≤51
Add 5 to both sides.
7h+5-5 ≤ 51+5
7h ≤ 56
h ≤ 8
So, the number of hours be less than equal to 8.
Complementary angels add up to 90°
so x+18°=90°
so x=90-18=72°
Answer:
52/63
Step-by-step explanation:
Given the expression;
4/7 * 13/9
WE are to take the product
= (4/9)* (13/7)
