Answer:
x=2/3
Step-by-step explanation:
(2x+1)/2 = 2 1/3/4
Multiply 4 on both sides:
2x+1=2 1/3
Rewrite:
2x+1=7/3
Subtract 1 on both sides:
2x=4/3
Divide 2 on both sides:
x=2/3
Thus x=2/3
Hope this helps!
Answer:
P = 57/1105
P = 0.052
Step-by-step explanation:
Given:
Total number of dummy tickets = 20
Total number of tickets with value = 10 + 10 + 12 = 32
Total number of tickets in the box = 20 + 32 = 52
The probability of picking 3 tickets randomly from the box without replacement and the three are dummy (with no value) is;
P = 20/52 × 19/51 × 18/50
(As each one is picked it reduces the total number of tickets and also the number of dummy tickets by one)
P = 57/1105
P = 0.052
B=cost per boquet
v=cost per vase
3b+5v=25.75
8b+2v=29.00
use eliminateion
divide 2nd equation by 2
4b+v=14.50
multiply it by -5 and add to other equation to eliminate v
-20b-5v=-72.5
<span><u>3b+5v=25.75 +</u></span><u />
-17b+0v=-46.75
-17b=-46.75
divide both sides by -17
b=2.75
a boquet costs $2.75
Answer:
Your answer would be the first option.
A right angle is 90 degrees
An obtuse angle is more than 90 degrees and that angle is more that 90 degrees
Y = 197
197 ÷ 13 = 15 and a remainder of 2
