This is all if you don't solve as a quadratic equation.
Look at the other answer.
Answer:
<em><u>x = 9.75</u></em>
Step-by-step explanation:
Step 1. Distribute the 2(Do 2 times 2x and 2 tiems 5)
4x + 10 = 49
Step 2. Subtract 10 from both sides.
4x = 39
Step 3. Divide it all by 4 to isolate the variable.
x = 9.75
<em>Answer:</em>
<em>x = 10</em>
<em>Step-by-step explanation:</em>
<em>Hi !</em>
<em>2(x - 3) = 14</em>
<em>2x - 6 = 14</em>
<em>2x = 14 + 6</em>
<em>2x = 20</em>
<em>x = 20 : 2</em>
<em>x = 10</em>
<em>Good luck !</em>
Answer: 1a. $190
b. The total cost of making 20 bracelets.
c. $350
d. The total cost of making 100 bracelets.
e. $1150
f. The total cost of making 500 bracelets.
g. 150 bracelets
h. 425 bracelets
Step-by-step explanation:
1a. C(20)=150+2(20)
C(20)=150+40
C(20)=$190
b. The total cost of making 20 bracelets.
c. C(100)=150+2(100)
C(100)=150+200
C(100)=$350
d. The total cost of making 100 bracelets.
e. C(500)=150+2(500)
C(500)=150+1000
C(500)=$1150
f. The total cost of making 500 bracelets.
g. 450=150+2b
2b=300
b=150 bracelets
h. 1000=150+2b
2b=850
b=425 bracelets
Answer:
To find the solution, plug in 8 for d
d=-3x2+16
8=-3x2+16 Subtract 8 from both sides
0=-3x2+8
Now, use the quadratic equation to solve for x
a=-3
b=0
c=8
x=1.63 or
C. 1.6s
Step-by-step explanation:
If you have 12 dollars and you buy 3 paper back books, they each cost the same amount. So you would divide 12 dollars among 3 books to get the same answer for all of them. 12 divided by 3 equals the answer.
Then if you have 28 dollars and you buy 7 paper back books, they all cost the same amount. So that would be 28 divided by 7, equals the same answer.
