Correct answer is the last one.
(-2+3)/(6+4)= 1/10
y+3=1/10(x + 4)
y + 3 = (1/10)x + 4/10
y + 30/10 = ( 1/10)x + 4/10
y = (1/10)x + 4/10 - 30/10
y = (1/10)x - 26/10
y = (1/10)x - 13/5
10(y = (1/10)x - 13/5)
10y = x - 26
-x + 10y = -26
<span>4(x+5) = 4x +5x
Simplify by distributing and combining like terms
</span>(4)(x)+(4)(5)=4x+5x
4x+20=4x+5x
4x+20=(4x+5x)
4x+20=9x
Subtract 9x from each side
4x+20−9x=9x−9x
5x+20=0
<span />
Subtract 20 from each side
−5x+20−20=0−20
−5x=−20
Divide each side by -5
-5x ÷ -5 = -20 ÷ -5
x = 4
P.S this was actually harder than most algebra problems, so don't beat yourself about it :D<span /><span /><span /><span /><span />
Answer:
1 Dime
14 Quarters
Step-by-step explanation:
d + q = 15
0.10d + 0.25q = 3.60
d = 15 - q
0.10d + 0.25q = 3.60
0.10(15 - q) + 0.25q = 3.60
1.5 - 0.10q + 0.25q = 3.60
0.15q = 3.60 - 1.5
0.15q = 2.1
0.15q/0.15 = 2.1/0.15
q = 14
d = 15 - q
d = 15 - 14
d = 1
