Answer:
19.4in
Step-by-step explanation:
1) formula for area of a triangle:
(b*h)/2=a
the area and height are already given so lets substitute them in the formula.
(b*23.8)/2=230.86
1) multiply by 2 on both sides
b*23.8=461.72
divide by 23.8 on both sides
b=19.4
the base is 19.4 in
hope this helps

Answer:
$0.22
Step-by-step explanation:
Now we know that 8 ounces total to $1.76. That means that in order to find how much 1 ounce costs, we will end up dividing both sides by 8
8 oz = $1.76
8 oz / 8 = $1.76 / 8
1 oz = $0.22
So, we now know that 1 oz is equal to 22 cents. You can also confirm your answer by multiple 0.22 by 8, and you'll see that you'll get 1.76

Step-by-step explanation:
x + (x + 2) = 158
2x + 2 = 158
-2 -2
2x = 156; divide both sides by 2, and you get x = 78
If x = 78, then x + 2 = 80
