Answer:
Step-by-step explanation:
the ratio of 24 to 36 is the same as x to 12
= 
then
12*(
)=x
= x
8 = x
that's it :)
Answer:
0.514
Step-by-step Explantion:
Denominator = 500 = 2^2 * 5^3
257/500 = 257/2^2*5^3 = 2*257/2*2^2*5^3 = 514/2^3*5^3 = 514/(2*5)^3 = 514/10^3 = 0.514
Answer:
x=4 y=10
Step-by-step explanation:
y=5x-10
y=3x-2
We'll use the 2nd equation as a basis :
y=3x-2
3x-2=5x-10
0=2x-8
8=2x
4=x
We then use y=3x-2 to find y:
y=3(4)-2
y=12-2
y=10
Answer:
(x + 8) (x-8)
Step-by-step explanation:
x^2-64
Solve
a^2 - b^2 = (a+b) (a-b)
Where a = x , b = 8
(x + 8) (x-8)
Average price=total price/total weight, let p be the average price:
p=(3*4+5*4*(100-20)/100)/8
p=(12+16)/8
p=$3.50/lb
