The rule for dilation (about the origin) is
(x,y)->(kx,ky) where k is the dilation factor.

Let's try a few points,
D(4,8)->D'(2,4)=((1/2)4,(1/2)8) => k=1/2
F(8,8)->F'(4,4)=((1/2)8,(1/2)8) => k=1/2
We can repeat the same verification with points E & G with the same results, so
Answer: scale factor is 1/2, or 0.5.

wariber [46]

1st Picture:
$3)- \frac{6}{7} +\frac {10}{11}
\\\\LCD:77
\\\\\frac{6}{7}* \frac{11}{11} + \frac{10}{11}*\frac{7}{7}= \frac{66}{77} + \frac{70}{77} = \frac{136}{77} = 1\frac{59}{77} 
 \\ \\ 4) 3\frac{6}{7}* 2 \frac{1}{10}= \frac{27}{7} * \frac{21}{10} = \frac{567}{70} =\frac{81}{10} = 8\frac{1}{10}
\\\\5)2\frac{1}{2}+3\frac{1}{3}
\\\\LCD: 6
\\\\ 2\frac{3}{6} + 3\frac{2}{6} =5\frac{5}{6}
\\\\6)5\frac{1}{8}*-6\frac{6}{11}=\frac{41}{8}* \frac{72}{11}=\frac{2952}{88}=\frac{369}{11}=33\frac{6}{11}$

2nd Picture:

$1)80 percent of 80 = .8*80 =64
\\\boxed{64}
\\\\2)95percent of 100=.95*100=95
\\\boxed{95}$

Answer:

x = no solutions

Division
Addition
Subtraction

Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define equation

4x - 5 = x - 1 + 3x

Step 2: Solve for x

Combine like terms: 4x - 5 = 4x - 1
Subtract 4x on both sides: -5 ≠ -1

Here we see that -5 does not equal -1.

∴ This equation has no solutions.
