We have that
an=<span>10 * 5n---------------> an=50*n
then
for n=1
a1=50*1=50
</span>for n=2
a2=50*2=100
for n=3
a3=50*3=150
for n=4
a4=50*4=200<span>
the answer is
</span><span>the first four terms are [50,100,150,200]</span><span>
</span>
11.) Since the standard coord. equation is "mx+b"
And since the "+b" portion is your y-intercept.
Your y-intercept would be the <span>$0.85 "for each topping"</span>
12.) Your equation needed is...
.75x+5 <span>≤ 14
x=12, meaning that she alone cannot ride more than 12 rides</span>
Simplify
-0.75x + 8 + 1.5x + 4.4
Collect like terms
(-0.75x + 1.5x) + (8 + 4.4)
Simplify
<u>0.75x + 12.4 </u>
-3(6x+5)-2(1-17x)=3(5+5x)
Mutiply the first bracket by -3
(-3)(6x)= -18x
(-3)(5)= -15
Mutiply the second bracket by -2
(-2)(1)= -2
(-2)(-17x)= 34x
Mutiply the third bracket by 3
(3)(5)= 15
(3)(5x)= 15x
-18x-15-2+34x= 15+15x
-18x+34x-15-2= 15+15x
16x-17= 15+15x
move 15 to the other side
sign changes from +15 to -15
16x-17-15= 15-15+15x
16x-32= 15x
move -32 to the other side
sign changes from -32 to +32
16x-32+32=15x+32
16x= 15x+32
move 15x to the other side
sign changes from +15x to -15x
16x-15x=15x-15x+32
x= 32
Answer: x= 32
