Answer: C
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
Opening the brackets, we have
5x – 5 = 20x –200
Collecting like terms, we have:
5x – 20x = –200 + 5
– 15x = –195
Dividing both sides by the coefficient of "x"
–15x/–15 = –195/–15
x = 13
Answer:
so Y= 150 + 50x
Step-by-step explanation:
so y = 150 + 50 x 2 will = 250
50 x 2 = 100
100 + 150Y
= 250
Answer:
5083
Step-by-step explanation:
6^3 + 5(8 + 15)
Simplify the bracket first
6 x 6 x 6 + 5 (23)
216 + 5 (23)
221 (23)
221 x 23 = 5083
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.
