Step-by-step explanation:
Given
Required
Using 
, what is the most expensive she can buy?
Subtract $15.32 from both sides
This means that she can not afford items that cost more than $13.68
i.e. the shin guards which costs $14.98
The items she can afford and their prices are:
The most expensive of them all is:
Answer:
Step-by-step explanation:
Solution by substitution method
3x+5y=7
and 4x-y=5
Suppose,
3x+5y=7→(1)
and 4x-y=5→(2)
Taking equation (2), we have
4x-y=5
⇒y=4x-5→(3)
Putting y=4x-5 in equation (1), we get
3x+5y=7
⇒3x+5(4x-5)=7
⇒3x+20x-25=7
⇒23x-25=7
⇒23x=7+25
⇒23x=32
⇒x=32/23
→(4)
Now, Putting x=32/23
in equation (3), we get
y=4x-5
⇒y=4(32/23)-5
⇒y=(128-115)/23
⇒y=13/23
∴y=13/23 and x=32/23
Answer:
a=4+2/x <-- 2 over x its a fraction
Step-by-step explanation:
Sinα=h/w
w=h/sinα, we are told that h=15 ft and α=70° so
w=15/sin70° ft
w≈15.96 ft (to nearest hundredth of a foot)
D— put 7 over 1 and then change division sign to multiplication & then flip 9/5 to 5/9
