Answer:
C. 25x+12y+4≤ 130
Step-by-step explanation:
Each ticket cost $25, so x would be the number of tickets she has to buy.
25x
Each T-shirt cost $12, so y would be the number of T-shirts she can buy.
12y
And since there is an service fee for the entree purchase, that's another $4.
+4
The cost of everything has to be less than $130, so the equation would be:
25x+12y+4≤ 130
Step-by-step explanation:
1) 3 – 36i = 9a + 4bi
3 = 9a => a = 3/9 = ⅓
-36 = 4b => b = -36/4 = -9
2) a – 15i = -7 – (2b-3)i
a = -7
-15 = -(2b-3)
2b-3 = 15
2b = 18
b = 18/2= 9
Answer:
Step-by-step explanation:
If AB = AD, then you have that triangle ABD is an isosceles triangle (it has two equal sides). If it is isosceles, then the angles opposite to angles those equal sides must be equal. Then angle ADB = 
. and by the property of all internal angles of a triangle have to add to 
, we get that:
Answer:1/6 plus 1/6 is 1/3
Step-by-step explanation:
Answer:
The missing y -coordinate is 0.
Step-by-step explanation:
Here we know the slope but must find the y-coefficient of one of the points.
y - 2
The slope is m = 1/2 = rise / run = ----------
3 - 7
y - 2
or 1/2 = ---------- which simplifies to -2 = y - 2, which yields y = 0.
-4
The missing y -coordinate is 0.
