Answer:
Equation: 5.5x = 168.5
Solution: 30 shirts
Step-by-step explanation:
First, create the equation where x is the number of shirts.
Since each shirt is $5.50, the cost of the shirts will be 5.50x
Set this equal to 168.50, since that is how much money Kareendeep has.
So, the equation will be 5.5x = 168.5
Now, solve this for x, the number of shirts she can buy:
5.5x = 168.5
Divide each side by 5.5
x = 30.6
Since we can only have a whole number of shirts, she can only buy 30 shirts.
So, the answer is 30 shirts.
Answer:
63.5
Step-by-step explanation:
The diagonals of a rhombus bisect opposite angles.
The longer diagonal bisects the 42° angle
The larger angle of the rhombus is 180 - 42 = 138
Let x = the length of the longer diagonal
You know two sides and the included angle of a triangle.
Using the law of cosines we get
x^2 = 34^2 + 34^2 - 2(34)(34) cos 138
= 1156 + 1156 - 2312 c0s 138
= 4030.1508...
x = sq rt 4030.1508...
= 63.5
