The correct answer is:
(n/5)-9
Answer:
6 1/3
Step-by-step explanation:
The numbers are constants, and the multiplication symbol is an operator.
If this equation were 4x * 6 = 24, then 4 would be a coefficient and x would be a variable. 6 and 24 are still constants and the multiplication symbol is still an operator.
Answer:
6x+4=16
Step-by-step explanation:
here you go does this work
Answer:
The cost of one shirt is $16 and the cost of one sweater is $20.
Step-by-step explanation:
Let the cost of one shirt be x and the cost of one shirt be y.
7x + 4y = 192 -----Equation 1
8x + 7y = 268 -----Equation 2
Equations 2-1:
8x + <em>7y</em> - 7x <em>- 4y</em> = 268 - 192
x + 3y = 76
x = 76-3y -----Equation 3
Subsitute x = 76-3y into Equation 1:
7x + 4y = 192
7(76-3y) + 4y = 192
532 - 21y + 4y = 192
532 - 17y = 192
-17y = 192-532
-17y = -340
17y = 340
y = 340 ÷ 17
y = 20 (The cost of one sweater is $20)
Substitute y = 20 into Equation 3:
x = 76-3y
x = 76 -3(20)
x = 76 - 60
x = 16 (The cost of one shirt is $16)
