X = -4
y = 1
that’s my closest guess
Answer:
21 quarters, 6 dimes, and 11 nickels
Step-by-step explanation:
# of Quarters = x.
# of Dimes = y.
# of Nickels = z.
(i)x = 3y+3.
(ii) 0.25x + 0.1y + 0.05z = 6.4
(iii) x + y + z = 38.
Multiplying (iii) by -0.05, and adding it to (ii),
we then get:
0.2x + 0.05y = 4.5.
Now plug in (i) into this.
0.65y + 0.6 = 4.5.
0.65y = 3.9
y = 6.
Since y = 6, we can subsitute this into our equation.
0.2x + 0.3 = 4.5
0.2x = 4.2
x = 21.
Since x = 21, y =6, then z = 11.
Both triangles are the same but ones bigger so that means
AB=RS
ST=BC
AC=RT
Which means
How many 6 go into 18
How many 3 go into 9
How many 5 go into 15
They all 3
So the answer is it is enlarged by 3
Here are the real answers to this besides the other person’s
Sub your values into the equation
if y = -1/6 x + b
6 = -1/6 * -6 + b
6 = 1 + b
b = 5
so y = -1/6x + 5
