No I do not think that 12/60 and 16/40 are equivalent because onec you reduce both of the fractions it does not equal.
The ratio of length for both triangle is 4 .
thus ,
5*4 = 20
3x + 8 = 20
x = 4
28 / 4 = 7
y + 5 = 7
y = 2
Answer:
75.4
Step-by-step explanation:
A=2πrh+2πr2=2·π·2·4+2·π·22≈75.39822
Answer:
45
Step-by-step explanation:
Let X= Cost of pears Let Y= Cost of peaches.
Solve question using a system of equations.
5X + 6Y = 11.20
3X = 2Y
Simplify the second equation to solve for Y.
3X = 2Y
Y = 1.5X
Substitute Y into the first equation.
5X + 6(1.5X) = 11.20
Simplify.
14X = 11.20
Solve for X:
X = 0.8
Substitute the value into one of the equations.
3X = 2Y
3(0.8) = 2Y
2.4 = 2Y
Y = 1.2
Each pear is $0.80 and each peach is $1.20.
Hope this helps!
