C= chair cost
t= table cost
Create two equations with the given information. Solve for one variable in equation one. Substitute that answer in equation two. Then you can solve for the needed information.
3c+2t=$18
5c+6t=$48
3c+2t=18
Subtract 2c from both sides
3c=18-2t
Divide both sides by 3
c=(18-2t)/3
Substitute the value for c in equation two:
5c+6t=$48
5((18-2t)/3)+6t=48
(90-10t)/3+6t=48
Multiply everything by 3 to eliminate fraction
(3)((90-10t)/3)+(3)(6t)=(3)(48)
90-10t+18t=144
90+8t=144
Subtract 90 from both sides
8t=54
Divide both sides by 8
t=$6.75 cost for table
Substitute the t value to solve for c:
3c+2t=18
3c+2(6.75)=18
3c+13.50=18
3c=4.50
c=$1.50 chair cost
Check:
5c+6t=$48
5(1.50)+6(6.75)=48
7.50+40.50=48
48=48

Answer:
x<1.5
explanation: move 4 to other side subtract it with 26.5 then divide it by 15
Answer:
24000
Step-by-step explanation:
If you would like to solve the equation 4/5 * x = 2/5, you can calculate this using the following steps:
4/5 * x = 2/5 /*5
4 * x = 2 /4
x = 2/4
x = 1/2
The correct result would be 1/2.
Answer:
21.67
Step-by-step explanation:
look at the number in the 0.01 value then the number next to it
if it's five or above then the 7 goes up if it's 4 and below then the number stays the same. in this case the number will stay the same
