The answer is (4,6) (4,3) (5,4)
Answer:
15 nickels were there with Alexis
Step-by-step explanation:
Let there be x nickels
given that
The number of dimes is 5 less than twice the number of nickels.
no of dimes in terms of x = 2*number of nickels - 5 = 2x - 5
we know that
value of 1 nickel = 5 cents
then
value of x nickel = 5*x cents = 5x cents
we know that
value of 1 dime = 10 cents
then
value of 2x-5 dime = 10(2x - 5) cents = 20x - 50 cents
Total value of x nickel and 2x -5 dimes = 5x + 20x - 50 = 25x - 50
given that
Alexia has total of $3.25 in nickel and dimes thus 25x - 50 must be equal to $3.25
$1 = 100 cents
$3.25 = 3.25 * 100 cents = 325 cents
Thus,
25x - 50 = 325
25x = 325 + 50 = 375
x = 375/25 = 15
Thus, no of nickels = x = 15 answer
It’s gonna have to be 5c2
Answer:
228
Step-by-step explanation:
first we will find the area of the triangles on the sides of the prism.
(triangle area formula: (b*h)/2)
(6*5)/2 = 15
we multiply this by 2 since there are 2 sides that contain the same measures:
15*2 = 30
then we find the rectangles that are on the sides (not the base)
(rectangle formula: b*h)
11*6.5 = 71.5
multiply this by 2 since there are two sides:
71.5*2 = 143
finally we find the base using the same formula as we did to find the rectangles:
11*5 = 55
finally we add them all up:
30+143+55 = 228
hope this helps! :)
Answer:
43 & 96
Step-by-step explanation:
x=one number
y=other number
x+y=139
x-y=53 x=y+53
substitute for x
y+53+y=139
reduce
2y+53-53=139-53
2y=86
2y/2=86/2
y=43
x=96
