(3/8)d=12 is the starting equation. You need to separate d from the rest of the numbers by dividing both side by (3/8) or multiplying both sides by the reciprocal of (3/8) which is (8/3).
Then multiply 12(8/3) which is 32.
(3/8)d=12
d=12(8/3)
d=32
Alyssa's dog weighs 32 pounds
Answer:
It is 7
Step-by-step explanation:
y = mx+b
y is the total cost.
x is the number of hours.
b : that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hours
Let z be any number (like x would be)
if we set z equal to 2x-6y, then we get z = 2x-6y
The system
2x-6y = 8
2x-6 = 3
turns into this new system
z = 8
z = 3
but z is a single number. It can't be both 8 and 3 at the same time. So there are no solutions
Answer:
The correct answer would be: D
Step-by-step explanation:
C is an interior angle, so it is out of question.
That leaves D, A, and B.
A and B are not correctly put in my opinion, because both angles are put in a circle probably suggesting it is equal to 360°, even though a whole trapeziods exterior angle alone is not supposed to equal to 360° because the entirety of it is supposed to be equivalent to that amount.
Leaving D, being the correct answer
I hope this helps
