Answer:
15 cm by 12 cm.
Step-by-step explanation:
Given:
Amanda uses a rectangular canvas for a panting.
The length is 
centimeters.
The width is 
centimeters, and is 4/5 of the length .
Question asked:
.What are the dimensions of the canvas ?
Solution:
<u>As given that the width is </u>
of the length.
Adding both sides by 
Subtracting both sides by 
By cross multiplication:-
By diving both sides by 70
<u>Now, substituting the value:-</u>
The length = cm
= 
The width = cm
= 
Thus, length and width of canvas are 15 cm and 12 cm.
Answer:
Step-by-step explanation:
m∠2 ≅ m∠7 [Alternate exterior angles]
m∠7 + m∠8 = 180° [Linear pair theorem]
m∠2 + m∠8 = 180° [Substitution property]
∠2 and ∠8 are supplementary [Definition of supplementary angles]
We can see that the lines intersect at (-5,3) on the graph, so that eliminates choices B and D. Both A and C say that the first line is y=x+8, which is true. A says that the second line is y+x=-2, and after isolating y, we get y=-x+2, which seems correct. Do the same for C, and you will find that it says the other equation is y=x-2, which is not true because it must have a negative slope. So your answer will be choice A.
