The cost of two tables and three chairs is $705. If the table costs $40 more than the chair,find the cost of the table and the c
Nadusha1986 [10]

Answer:

the cost of the table is \$165

the cost of the chair is \$125

Step-by-step explanation:

Let

x-----> the cost of the table

y----> the cost of the chair

we know that

2x+3y=705 -----> equation A

x=y+40 -----> equation B

substitute equation B in equation A

2(y+40)+3y=705

2y+80+3y=705

5y=705-80

y=625/5

y=\$125

Find the value of x

x=y+40  ----> x=125+40=\$165

Slove this question c^2-81=0
Firdavs [7]
To solve a square root, get the ^2 on one side and the 81 on the other side.
add 81 to both sides.

c^2 = 81
to clear the power of 2, take the square root of both sides.
c = + - sqrt81
c = + - 9
c = 9 and c = -9
