Answer:
yes it is all obtuse angles have measures greater than 90°.
Answer:
5 a^3 c
Step-by-step explanation:
5 • a • a • c • a
There are 3 a's so it becomes a^3
5 a^3 c
Answer:
y=3
Step-by-step explanation:
5y-2(3)=9
5y-6=9
+6 +6
5y=15
/5 /5
y=3
Answer:
Total cost = <em>$</em> 4.55
Step-by-step explanation:
2(8a + 5b) -(2a + 3b)
<em>Part A: Simplify the expression shown above</em>
Exapanding the brackets;
16a + 10b - 2a - 3b
Collecting like terms;
16a - 2a + 10b - 3b
14a + 7b
<em>Part B: If a represents apples that cost $0.25 each and b represents bananas that cost SO. 15 each, what is the total cost based on the expression above?</em>
a = 0.25
b = 0.15
14a + 7b
Inserting the values into the equation;
14 (0.25) + 7(0.15)
Total cost = <em>$</em> 4.55
