Answer:
$151.88 costs to Dan algebraic form
$245/2 = $122.50+20+15 = 157.5 is the answer though.
Step-by-step explanation:
35x+20(x-1)
35x + (20x -1)
35x +20x -1
35x -20x-20
x= 53/11
53/11 = 4.81
4.81 x 20 = $96.20 on chairs
4.81 x 15 = 72.15 on umbrella
96+72 = 168.35
245-168.35 = 76.65
76.65 + 20 = 96.65
Because we subtracted to get 168.35 we have the difference of $15 which is the difference of what he and she paid we half this amount = $7.50 half the 0.45 additional found on Dans $96.65 = $0.22 and find $7.72 balance to add to his 96.20
Added together his costs out of 245 was $104.37+ 76.65 = $181.20
Costs of umbrella = 76.65/2 = 39.325
181.20 -29.325=151.87 rounded up to 151.87
As x = 53/11 the decimal of this is 4.81 = x
Answer:
1.052
Step-by-step explanation:
Add 1 to the percent increase.
1 + 5.2% = 1 + 5.2/100 = 1 + 0.052 = 1.052
Answer: 1.052
First, we need the probability of picking an odd number.
There are 5 cards in total, and 3 odd cards (3, 5, and 7).
That means that the probability that we'll draw an odd card would be 
.
Then, we have 4 cards left, and 2 even cards (4 and 6), meaning that the probability that we draw an even card will be 
or 
.
To find the probability that these would happen in consecutive draws, we just multiply the probabilities together.
or 0.3.
To convert this into a percentage, we multiply the decimal by 100.
.
So the probability of picking an odd number and then picking an even number is 30%.
Hope this helps!
Asssuming blanks are plus
5(x+1)=4(x+8)
distribute
a(b+c)=ab+ac
5(x+1)=5x+5
4(x+8)=4x+32
5x+5=4x+32
minus 4x from both sides
x+5=32
minus 5 from both sides
x=27
Answer:
To find the intercepts, equate one variable to
0
and solve for the other variable:
y-intercept
Set

Next. we can plot the two points on the grid:
graph{((x-5)^2+(y)^2-0.125)((x)^2+(y+3)^2-0.125)=0 [-20, 20, -10, 10]}
Then, draw a line through the two points:
graph{(3x - 5y -15)((x-5)^2+(y)^2-0.125)((x)^2+(y+3)^2-0.125)=0 [-20, 20, -10, 10]}
