5x - 15 = 50
Add 15 to both sides
5x = 65
Divide both sides by 5
x = 13
Hope this helped :)
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
Use combination
There are 4 queen cards in a deck of 52 cards
Probability = 4C2 / 52C2
I calculate 4C2 first
4C2 = 4! / (2! 2!)
4C2 = (4 × 3 × 2 × 1) / (2 × 1 × 2 × 1)
4C2 = 6
Then I calculate 52C2
52C2 = 52! / (50! 2!)
52C2 = (52 × 51)/2
52C2 = 1.326
Hence, the probability is
Probability = 4C2 / 52C2
Probability = 6/1,326
Probability = 1/221
Answer:
1) x > -12
Step-by-step explanation:
first, subtract 7 from each side of the inequality to get:
-2/3x < 8
multiply each side by the reciprocal of -2/3 which is -3/2 to get:
x > -24/2
notice the symbol has been reversed because that is the rule whenever you multiply or divide an equality be a negative value
simplified, answer is x > -12
1/2 of 2 is 1 .
1/2 of 3 is (1 and 1/2).
1/2 of 4 is 2 .
