Answer:
75 + 25d > 250
d > 7
Step-by-step explanation:
Number of signatures needed : > 250
Amount of signatures ready = 75
Exoected number of signatures per day = 25
Number of days, d, needed signatures will be collected ;
Number of ready signatures + (expected number of signatures per day * number of days) > number of signatures needed
Mathematically,
75 + 25d > 250
25d > 250 - 75
25d > 175
d > 175 / 25
d > 7
Answer:
B
Step-by-step explanation:
Since <u>/</u>AOC = <u>/</u>BOC + <u>/</u>AOB, you fill in the numbers -
85 = 2x + 10 + 4x - 15
Then you combine like terms -
85 = 6x - 5
Then you add 5 to both sides -
90 = 6x
Then you divide by 6 -
15 = x
Then you substitute the x in the angles -
<u>/</u>BOC = 2(15) +10
<u>/</u>AOB = 4(15) - 15
Simplify the numbers and you get -
<u>/</u>BOC = 40
<u>/</u>AOB = 45
Parking lot A equation- $3.00 + $9.00x
Parking lot B equation- $10.00 + $6.00x
Part A- For 3 days parking lot B would be the better option- $28
Part B- For 8 days parking lot B would also be the better option- $58

Answer:
65
Step-by-step explanation:
let the son's age be x then the man's age is 5x
In 13 years
son's age = x + 13 and man's age = 5x + 13 and he is 3 times as old as son
5x + 13 = 3(x + 13)
5x + 13 = 3x + 39 ( subtract 3x from both sides )
2x + 13 = 39 ( subtract 13 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13 ← son's present age
5x = 5 × 13 = 65 ← man's present age
