The 3 angles of a triangle will add up to 180 degrees.
5x + 2x + 3 + 3x - 3 = 180...combine like terms
10x = 180
x = 180/10
x = 18
one angle is : 5(x) = 5(18) = 90 degrees
the other angle is : 2x + 3 = 2(18) + 3 = 39 degrees
the last angle : 3x - 3 = 3(18) - 3 = 51 degrees
Answer:
Step-by-step explanation: l = 5 + w
p = 168
...
p = 2l + 2w
168 = 2(5+w) + 2w
168 = 10 + 2w + 2w
168 - 10 = 4w
158 = 4w
1 = 5 + 39.5
Answer:
Step-by-step explanation:
Let x represents the number of red roses and y represents the number of white roses.
Given : Javier is purchasing a bouquet of roses from a floral shop. He wants the bouquet to have at least 12 roses.
i.e. the required inequality for this statement will be :-
No. of red roses +No. of white roses ≥ 12
i.e.
Also, Red roses cost $2.75 each and white roses cost $3.50 each and he wants to spend less than $35.
i.e. $2.75(No. of red roses)+$3.50(No. of white roses)≤ $35
i.e.
Now, From (1) and (2) the system of inequalities represents the situation :
