answer is down below
Step-by-step explanation:
u have ur two brackets.
(9b+3)(b-7)=0
take 1 bracket at a time
9b+3=0
solve it so:
9b+3=0
9b=-3
b= -3 / 9
<u>Ans: b=-1/3</u>
take the other bracket
b-7=0
solve it:
<u>Ans: b=+7 </u>
Answer:
5 dollars
Step-by-step explanation:
Let's call the price of a package of pens n, and the cost of a box of paper r.
3n+r=26
2n+7r=49
Multiply the first equation by 7:
21n+7r=182
Subtract the second equation from the first:
19n=133
Divide both sides by 19 to isolate n:
n=7
Plug this back in to find the value of a box of paper:
3(7)+r=26
21+r=26
r=5
Hope this helps!
You need to divide the 3 blocks of clay by the 4 friends. 3 goes in the dividend and the 4 is outside. 3 divided by 4 is equal to 0.75 or 3/4, so each friend gets 0.75 or 3/4 clay
Your 3rd option, or (-6,-3,0,3,6) would be the answer
