If <span>opposite angles of a quadrilateral add to 180 then it is called a cyclic quadrilateral and a circle can be inscribed in it. Here, the opposite sides are 115 and 65 (=180), and 90 and 90 (=180), which means that it is <u>true </u>that a circle can be circumscribed about the quadrilateral above.</span>

Jeremiah went to the grocery store and bought a soda for $2 and 6 sandwich costing, x dollars. The tax on the food was a 25% inc

mrs_skeptik [129]

<h3>Answer:</h3>

A) 1.25(2 +6x)
B) $40

<h3>Step-by-step explanation:</h3>

A) Let's first consider the effect of the tax:

total payment = (food cost) + 25% × (food cost) = (1 + 0.25)×(food cost)

If the cost of a sandwich is x dollars, the cost of 6 sandwiches will be 6 times that, or 6x dollars. When the $2 cost of the soda is added, we get ...

food cost = 2 + 6x

Putting this into the equation for total payment, we find the expression to be ...

total payment = 1.25(2 +6x)

_____

B) Evaluating the expression for part A with x=5, we get ...

total payment = 1.25(2 +6·5) = 1.25·32 = 40 . . . . dollars

Theo has $5 more than Denise and Denise has $11 more than Rudy. Together they have $45. How much money does Denise have?

Blizzard [7]

Let
x------> amount of money Theo has
y------> amount of money Denise has
z------> amount of money Rudy has

we know that
x+y+z=$45-----> equation 1
x=5+y-----> equation 2
y=11+z----> equation 3

substitute equation 2 in equation 1
[5+y]+y+z=45-------> 2y+z=40-----> equation 4

y=11+z----> equation 3
2y+z=40-----> equation 4

resolves the equations system
using a graph tool
see the attached figure

the solution is
y=17
z=6
x=5+y----> x=5+17----> x=22

the answer is
<span>Denise has $17</span>

I need help on number 12

faltersainse [42]

Angle ACD and angle CAD are angles that add to 90 degrees (60+30 = 90) and they are non-adjacent. They do not share a common vertex. So this is why the two angles fit the description for number 12.

In contrast, two adjacent complementary angles are angle FDG and angle GDE. They add to 90 degrees and share the common vertex point D. They also share a common segment DG.
