Answer:
4+11=15
Step-by-step explanation:
c=4 11=b
4(c) + 11(d) = 15
Step-by-step explanation:
you have the formula and the numbers. just calculate !
cost of membership
y = 100 - 0.02x
a)
for x = 2600
y = 100 - 0.02×2600 = 100 - 52 = $48
b)
the reduction element of the cost of membership is the
"- 0.02x" part.
we want to refuse the membership costs by $41, so
0.02x = 41
x = 41/0.02 = $2,050
c)
the same as b)
just now the membership costs need to be reduced to 0.
so, that means we need to reduce by $100 !
0.02x = 100
x = 100/0.02 = $5,000
5x + 2y = 7 . . . (1)
y = x + 1 . . . (2)
Putting (2) into (1) gives
5x + 2(x + 1) = 7 => 5x + 2x + 2 = 7 => 7x = 7 - 2 = 5 => x = 5/7
From (2) y = 5/7 + 1 = 12/7
Therefore, solution is {(5/7, 12/7)}
Answer:
1 7/24.
Step-by-step explanation:
7/8 + 3/4 - 1/3 The LCD of 3,4 and 8 is 24 so we have:
21/24 + 18/24 - 8/24
= 39/24 - 8/24
= 31/24
= 1 7/24.
Answer:
The corresponding angles theorem works for cases where we have two parallel lines intersecting another line.
Two lines are parallel if, at any point, the distance between these two lines is always the same.
Now, if we look at the image, we can see that the distance between the two horizontal lines changes (is smaller at the right and larger at the left)
Thus, these lines are not parallel.
Then the corresponding angles theorem can not be used here, and we have that:
∠9 ≠ ∠10
