Answer:
AC= 20
Step-by-step explanation:
since the two figures are similar, CB Is congruent to FD
since image/preimage, 12/3 =4
The dilation is 4.
AC is congruent to EF
EF=5
4 x 5 = 20
AC=20
someone correct me if im wrong :)
Answer:
Step-by-step explanation:
-17(y - 2) = -17y + 64
-17y + 34 = -17y + 64
-17y + 17y = 64 - 34
0 = 30 (incorrect)
this system has NO SOLUTIONS
Answer:
Altogether they lost 150 pennies.
Step-by-step explanation:
X = Dante's pennies
Y = Mia's pennies
X + Y = 350 1/2 X = 2/3 Y
X = 4/3 Y
4/3 Y + Y = 350
7/3 Y = 350
Y = 350 * 3/7
Y = 50 * 3
Y = 150
X + 150 = 350
X = 200
1/2 * 200 = 2/3 * 150
100 . = 100
1/2 * 200 = 100 -> Dante lost 100 pennies
1/3 * 150 = 50 -> Mia lost 50 pennies
Altogether they lost 150 pennies.
