Let’s take x as the price of a taco and y as the price of a serving of nachos.
22x + 17y = 71.05. First order
10x + 5y = 27.25. Second order
Multiply the first order by 5 and the second order by 11
110x + 85y = 355.25
110x + 55y = 299.75
Subtract
30y = 55.5
y = 1.85
So 10x + 5x1.85 = 27.25
10x = 27.25 - 9.25 = 18
x = 1.8
So each taco cost $1.80 and an order of nachos cost $1.85
Answer: 10y^4
Since it can go 10y^4(3y^4+1)
Step-by-step explanation:
Answer:
X = -19
Step-by-step explanation:
Add x to both sides to get rid of -x
-163 = 13x + 84
subtract 84 from both sides
-247 = 13x
divide by 13
x = -19
Answer:
Step-by-step explanation:
|√2-y|=|y-√2|
√2-y=±(y-√2)
when √2-y=y-√2
y+y=√2+√2
2y=2√2
y=√2
when √2-y=-(y-√2)
√2-y=-y+√2
or 0=0
it gives no value of y.
so only possible value is y=√2
Hello!
The statement that is true about the three quadrilaterals is the first one:

____________________________________________________________
Option #2 is incorrect because although E and F are similar, they are not congruent. They do not have the same size.
Option #3 is also incorrect because, again, D and E are similar, but they are not congruent.
Option #4 is not correct because it says that "F and D are similar but not congruent." This is not true since they are the same shape and size. Only their orientation is different, which makes them congruent.
