Answer:
question 9
= –12
while question 11=, x= –72
Step-by-step explanation:
question 9=
u= –16+4= –12
question 11=
cross multiplication
x = -36 multiplied by 2 =
-72
I HOPE THIS HELPED IF WRONG IM SORRY
Answer:
x > 2.8
Step-by-step explanation:
x < -x + 7(x - 2)
Expand using the Distributive Property
x < -x + 7x - 14
x < 6x - 14
Subtract x from both sides
0 < 6x - 14 - x
0 < 5x - 14
Add 14 for both sides
5x > 14
x > 14/5
x > 2.8
Let p and c be the pieces of pie and cake respectively.
We have p+ c= 100 (because the total number of pieces of pie and cake is 100).
On the other hand, we have $4p+ $5c= $473
or 4p+ 5c= 473
p+c=100
4p+5c=473
Solving the set of equations above, we have: p= 27, c=73.
They sold 27 pieces of pie~
Answer:
y = 3
Step-by-step explanation:
(Assuming that 2x - 11 = y)

Answer:
133 degrees
Step-by-step explanation:
The angle 47 degrees is on a straight line, and the angles on a straight line add up to 180 degrees.
So, to find the angle parallel to 47 degrees, subtract 47 degrees from 180 degrees
180 - 47 = 133 degrees
Now, the relationship between the angle that is 133 degrees and the angle of x is that they are corresponding angles.
And corresponding anglea are the same.
Thereforw, x = 133 degrees
hope this helps :)
