Answer: 5th week
Step-by-step explanation:
E= -12w+568
520= -12w+568
520+12w=568
12w=48
w=4
4+1=5th week
Answer:
To find the LCM you must find all factors of the numbers, and then multiply all the factors together including the ones that are not shared among the numbers.
For example,
Factors of 10: 2×5
Factors of 30: 2×3×5
LCM of 10 and 30: 2×3×5 = 30
However do note not to multiply a factor more than once if it is shared among two numbers.

Answer:
The additional information required to prove ΔDEF ~ ΔPQR is the value of the ratio DE/PQ which has to be equal to three-halves for ΔDEF to be similar to ΔPQR
Step-by-step explanation:
Given DF/PR = FE/RQ = 3/2
The Side Side Side, SSS, similarity theorem states that where there are two triangles that have corresponding sides that are proportional to each other, the two triangles are said to be similar
Given ΔDEF and ΔPQR, have sides DF/PR = FE/RQ, to prove that ΔDEF and ΔPQR, then the additional information required is the ratio of the third sides of the triangles which is DE/PQ.
If DE/PQ = Three-halves, the two triangles ΔDEF and ΔPQR are similar, if not, that is DE/PQ ≠ Three-halves, then the two triangles ΔDEF and ΔPQR are not similar.
