I believe it is the last answer choice
Answer:
x=5
Step-by-step explanation:
since it’s isosceles trapezoid, diagonals are equal.
x+10=2x+5
x=5
<em><u>Question:</u></em>
An Internet business charges a flat rate of $6.50 for shipping. If x represents the cost of the items purchased and y represents the total cost with shipping, which equation best represents the relationship between x and y?
<em><u>Answer:</u></em>
y = 6.5 + x represents the relationship between x and y
<em><u>Solution:</u></em>
Given that,
An internet charges a flat rate of $6.50 for shipping
Let "x" be the cost of items purchased
Let "y" be the total cost with shipping
Therefore,
Total cost with shipping = flat rate of 6.50 + cost of items purchased
Thus, we get,
y = 6.50 + x
y = 6.5 + x
Thus the above equation represents the relationship between x and y
Answer:
D. 340 square inches
Step-by-step explanation:
Side length translates to 1 side of the square, so you do 10 x 10 to find the area of the square.
10 x 10 = 100
The triangle one isn't much more difficult. The formula for finding the area of a triangle is bh1/2
So:
10 x 12 = 120/2=60
From there just multiply the result by 4- the amount of triangles on the square pyramid, and you'll get your answer.
60
x 4
240 + 100 = 340 square inches
