Answer:The sitting fee is 15 dollars
Step-by-step explanation:If you were to use the formula y=mx+b then the starting equation would be y=12x+b. It already gave you the cost for the amount of photos respectively so 51=12(3)+b. 12 times 3 equals 36 and 51 minus 36 equals 15. The same way would be used for 87 dollars and 123 dollars while using the amount of photos respectively. 87=12(6)+b. 12 times 6 equals 72. 72 plus 15 equals 87. 123=12(9)+b. 12 times 9 equals 108. 108 plus 15 equals 123. Therefore the sitting fee is 15. (51=12(3)+15, 87=12(6)+15, 123=12(9)+15)
Answer:
4 over 5
Step-by-step explanation:
The simplist form of 8/10 is 4/5.
A) 2(5x-3)=24
*Distribute the 2*
10x-6=24
*Add 6 to both sides*
10x=30
*Divide both sides by 10*
ANS: x=3
b) 5(2x+1)=50
*Distribute the 5*
10x+5=50
*Subtract 5 from both sides*
10x=45
*Divide both sides by 10*
x=45/10
*Simplify by dividing numerator and denominator by GCF (5)
ANS: x=9/2
Hope this makes sense!
