Shortest side (a) = 58
middle side (b) = 64
longest side (c) = 77
the 3 sides a + b + c = 199
b = a + 6
c = a + 19
substitute your new values for b & c into your original formula, so:
a + (a+6) + (a+19) = 199
3a + 25 = 199
3a = 174
a = 58
then substitute 58 into your b & c formulas to figure out the rest
b = a + 6 = 58 + 6 = 64
c = a + 19 = 58 + 19 = 77
Hello!
You solve this algebraically.
6(t - 2) = 2(9 - 2t)
Distribute the 6
6t - 12 = 2(9 - 2t)
Distribute the 2
6t - 12 = 18 - 4t
Add 4t to both sides
10t - 12 = 18
Add 12 to both sides
10t = 30
Divide both sides by 10
t = 3
The answer is 3
Hope this helps!
Answer:
- 9 students : 1 table
- 87 pebbles per aquarium
- 10 slices for each child
Step-by-step explanation:
A "unit" rate is one that has a denominator of 1 unit.
12 apples : 3 baskets has a denominator of 3, so is not a unit rate. It could be made into a unit rate of 4 apples : 1 basket by dividing the numbers by 3.
Similarly, $5 for 4 muffins has a denominator of 4, so is not a unit rate. The equivalent unit rate is ($5/4) per muffin, or $1.25 per muffin.
All of the other offered choices are unit rates. (See list above.)
Answer:
It is an imaginary number.
Step-by-step explanation:
In this example, the real number is -2 is being multiplied by the imaginary unit, i, which i can be also expressed as (√-1).
