Answer:
53lbs
Step-by-step explanation:
if he bought three bags of gravel that are 20 lbs. each then he would have 60 lbs. of gravel. In the end he only had 7 pounds left so you would subtract 7 from 60 and get 53 pounds.
7+x=60 or 60-7=53

Answer:
Answer:
y=
d−4
/c+9
Step-by-step explanation:
cy+4=d−9y
Step 1: Add 9y to both sides.
cy+4+9y=d−9y+9y
cy+9y+4=d
Step 2: Add -4 to both sides.
cy+9y+4+−4=d+−4
cy+9y=d−4
Step 3: Factor out variable y.
y(c+9)=d−4
Step 4: Divide both sides by c+9.
y(c+9) c+9
=
d−4
/c+9
y=
d−4
/c+9
Answer: AAA similarity.
Step-by-step explanation: CB is the transversal for the parallel lines AB and DE, and so by transverse property, we have ∠CED ≅ ∠CBA. Similarly, CA acts as a tranversal for the same pair of parallel lines AB and DE and using the same property, we can have ∠CDE ≅ ∠CAB. Now, in triangles CED and ABC, we have
∠CED ≅ ∠CBA,
∠CDE ≅ ∠CAB
and
∠DCE ≅ ∠ACB [same angle]
Hence, by AAA (angle-angle-angle) similarity,
△CED ~ △ABC.
Thus, the correct option is AAA similarity.
