The length of a picture is 8 times the difference of the width and 4. If the the length of the picture is 16 cm, find the width
1 answer:
Answer:
The width of the picture is 6 cm
Step-by-step explanation:
The length of the picture cm
The width of the picture cm
The length of a picture is 8 times the difference of the width and 4, so
- the difference of the width and 4
cm
- 8 times the difference of the width and 4
cm
- the length of the picture is 8 times the difference of the width and 4, so
Divide the equation by 8:
Rewrite it:
Add 4:

Answer:
PQ = 6.8
Step-by-step explanation:
Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:
LN/OQ = MN/PQ
LN = 5
OQ = 17
MN = 2
PQ = ?
Plug in the values
5/17 = 2/PQ
Cross multiply
5*PQ = 2*17
5*PQ = 34
PQ = 34/5
PQ = 6.8
