Answer:
Step-by-step explanation:
Let d represent the number of dimes. Then 40-d is the number of nickels. The value is ...
0.10d +0.05(40 -d) = 2.60
0.05d = 0.60 . . . . . subtract 2.00
d = 0.60/0.05 = 12 . . . . . the number of dimes
40 -d = 40 -12 = 28 . . . . .the number of nickels
__
There are 0 quarters. There are 28 nickels.

Answer:
all sides are 7 units
Step-by-step explanation:
Since the triangle is equilateral then all 3 sides are equal in length
equate any 2 sides and solve for d
KL = LM
d + 2 = 12 - d ( add d to both sides )
2d + 2 = 12 ( subtract 2 from both sides )
2d = 10 ( divide both sides by 2 )
d = 5
KL = d + 2 = 5 + 2 = 7
LM = 12 - d = 12 - 5 = 7
KM = 4d - 13 = (4 × 5) - 13 = 20 - 13 = 7
Answer:
58
Step-by-step explanation:
58.58 - 0.58 = 58
Solpe intercpt form is y=mx+b
m=slope
b=y intercept
so exg
if you have
3x+8y=8
subtract 3x from both sides
8y=3x+8
divide boh tsides by 8
y=8/3x+1
y intercpt=1
slope=8/3
