Answer:
D
Step-by-step explanation:
x + 5 + 3x + C = 180 All triangles have 180 degrees.
4x + 5 + C = 180
But C must be equal to 3x. Notice the markings on the lets of the triangle.
4x + 5 + 3x = 180
7x + 5 = 180 Subtract 5 from both sides
7x = 180 - 5
7x = 175
x = 25
But angle C = 3x
C = 3*25
C = 75
Since
and
, we have

So, the equation becomes

The solutions to this equation are 4 and -5/2, so I'm afraid there's a typo in your question.
Answer:
$1.51
Step-by-step explanation:
1.25 lb. of dried fruit : 
0.5 lb. of cereal : 
Cost = $2.30 + $1.19 = 3.49
Money = $5
$5 - $3.49 = $1.51 in change
Answer:
The equation for the given maths problem is $ 34 + $ 8x = $ 90
Step-by-step explanation:
According to question :
The Total amount spent on cloths = $ 90
The cost of a pair of jeans = $ 34
The cost of each t-shirt pair = $ 8
The amount spent on t-shirt = $ 90 - $ 34 = $ 56
Let the number of t-shirt pair = x
So, $ 34 + $ 8x = $ 90
Or, $ 8x = $ 90 - $ 34
∴ x = 
Hence The equation for the given maths problem is $ 34 + $ 8x = $ 90 Answer
