D because the x-intercept would be 1/3, not 3
Answer:
The answer is b (50.24)
step-by-step explanation:
A=πr2=π·42≈50.26548
To find a unit rate, you should set the original unit to 1 and account for the other value appropriately. In this case, you would divide both sides by 5, which reveals that at a rate of $7.96 for 5 pounds, it is $1.59 per pound.
Answer:
A, B, C, D, E
Step-by-step explanation:
AB ≅ AC and AD bisects ∠A
This is given information from the diagram and the statement.
∠BAD ≅ ∠CAD
This is from the definition of angle bisector.
AD ≅ AD
This is reflective property of congruence.
ΔABD ≅ ΔACD
From the previous three statements, side-angle-side congruence tells us the triangles are congruent.
∠B ≅ ∠C
Corresponding parts of congruent triangles are congruent.
first subtract the last equation from the first. this gives:-
-x + y = -8 .....................(1)
Then multiply the first equation by 2 and add it to the 2nd equations This gives
9x = 18
so x = 2
and from equation (1) y = -8 + 2 = -6
Substituting for x and y in the second equation
z = (24 -5(2) -12) / 2 = 1
Answer is choice b.
