What do you mean by that?
Answer: 6 large frames and 12 small frames
Step-by-step explanation:
We define the following:
x = number of large frames
y = number of small frames
Make the following equations:
x + y = 18
19x + 9y = 222
Use system of equations to solve. We find the value of x first.
y = 18 - x
⇒ 19x + 9(18 - x) = 222
⇒ 19x + 162 - 9x = 222
⇒ 10x + 162 = 222
⇒ 10x = 60
⇒ x = 6
Find value of y:
6 + y = 18
y = 12
∴ 6 large frames and 12 small frames were purchased.
The answer to this question is A $1.42 because the first customer paid $12 for 14 postcards
The only that has the shape of the one below.
y = -4(x^3 + 7x^2+8x - 16)
Let x = 1
y = - 4(1 + 7 + 8 - 16)
y = 0
y = -4(x -1)(x^2 + 8x + 16)
y = -4(x - 1)(x + 4)^2
Here, EJI + FJE = 180 [ Linear-Pair Equation ]
FJE + 135 = 180
FJE = 180 - 135
FJE = 45
Now, FJH + FJE = 180 [Linear-Pair Equation ]
FJH + 45 = 180
FJH = 180 - 45
FJH = 135
Hope this helps!
