Answer:
A) 4*4x-4*3 and 16x-12
B) 12y+15y and 27y
Step-by-step explanation:
For A when you do the distributive property, you get:
4(4x-3)
4*4x-4*3 (which is one of the choices)
16x-12 (which is one of the choices)
For B when you combine like terms, you get:
12y+5y+10y
12y+15y (which is one of the choices)
27y (which is one of the choices)
Answer:
the area in square yards is 100πyd^2
Step-by-step explanation:
The computation of the area is shown below:
Area = πr^2
= π10^2
= 100πyd^2
Hence, the area in square yards is 100πyd^2
We simply applied the above formula to determine the area
Answer:
see below
Step-by-step explanation:
Let f = number of friends
all but one friend got 6 pieces and 1 friend got 2 for a total of 50 pieces
6(f-1) + 2 = 50
Subtract 2 from each side
6(f-1) +2-2 = 50-2
6(f-1) = 48
Divide by 6
6(f-1)/6 = 48/6
f-1 = 8
Add 1 to each side
f-1+1=8+1
f=9
Jack has 9 friends at the party
With Jack and his mom, there are 11 people
<em><u>The correct answer is 60 seats on the left side</u></em>, but you might also want to know how I got that answer . . .
Let's say, n = number of rows
Since we know the airplane has an equal number of rows on the right side as it does on the left side, then we can mathematically show that:
number of sears on the right side = 3n = 90 seats
number of sears on the left side = 2n = ? seats
3n = 90
n = number of rows = 90/3 = 30 rows
Thus:
2n = 2(30) = <u><em>60 seats on the left side</em></u>
<em>as for how many seats all together, just add . . 90 + 60 = 150 seats total</em>
| 3x - 1 | + 7 = 2
| 3x - 1 | = 2 - 7
| 3x - 1 | = -5.....no solution because an absolute value cannot equal a negative number.
| 2x + 1 | + 4 = 3
| 2x + 1 | = 3 - 4
|2x + 1 | = -1...same thing...no solution..cannot equal a neg. number
so Eq. 1 and Eq. 2 both have NO SOLUTIONS :)
