Answer:
The cost for 1 chair is $2.75 and the cost for 1 table is $8.75
Step-by-step explanation:
Use the elimination method of linear equations to find your answer.
Our equations for this problem are:
3c+5t=52 and 9c+7t=86
1. Multiply the entire first equation by -3.
-3(3c+5t=52)
2. Simplify the equation from above:
-9c-15t=-156
3. Stack the two equations on top of each other and add/subtract:
-9c-15t=-156
9c+7t=86
4. You should be left with -8t=-70. Simplify this to find the value of t:
t=8.75
5. Plug the value of t into any of the original equations and solve for c.
3c+5(8.75)=52
6. Simplify the equation above:
3c+43.75=52
7. Subtract 43.75 from both sides of the equation:
3c=8.25
8. Divide both sides by 3 to get your c value:
c=2.75
Answer:
<h2>$1.44</h2>
Step-by-step explanation:
Simply divide 11.5 by 8
8 goes into 11 1 time with 3 left over.
8 goes into 35 4 times with 3 left over.
8 goes into 30 3 times with 6 left over.
8 goes into 60 7 times with 4 left over.
8 goes into 40 5 times.

<h2>Answer $1.44 a Crayon</h2>
Judi's share was (7 x $2.50) = $17.50 .
That was really one share out of eight.
So the total bill was
(8 x $17.50) = $140.00 .
He can mow 12 lawns in 4 hours.
to get the answer you just multiply the amounts of lawns he mowed by the hours it’s asking.
