Answer:
x=7
y=18
The length of each of the two shorter sides is 14.
The length of each of the two longer sides is 19.
Step-by-step explanation:
2x+5 = x+12 and y-4 = x+5
Solve for x first
2x+5-5 = x+12-5 Subtract 5 from both sides to eliminate it.
2x-x = x-x+7 Subtract x from both sides to eliminate it.
x=7 Now, substitute 7 for x in y-4 = x+5 to solve for y.
y-4 = (7)+5
y-4 = 12
y-4+4 = 12+4 Add 4 to both sides to eliminate it.
y = 18
Finally, we can substitute 7 for x and 18 for y in all equations to see the lengths of each side.
(18)-4=14 The length of each of the two shorter sides is 14.
2(7)+5=19 The length of each of the two longer sides is 19.
Answer:
3.36 or 336/100
Step-by-step explanation:
2 4/5 x 2 x 3/5 = 3.36 in decimal form or 336/100 in fraction form
Answer:
the relationship between fractions, decimals and percents is that they are just different numerical expressions of the same value.
Step-by-step explanation:
For example, 50% = 
= 0.50
It's a rational number because 25 is perfect square, taking the square root gives the rational integers +5 or -5
