Answer:

1. \: 2 \frac{1}{6}  \\ 2. \:  \frac{8}{9}  \\ 3. \: 4 \frac{5}{7}  \\ 4. \: 4 \frac{9}{10}

Step-by-step explanation:

<h2>1</h2>

5 \frac{1}{2}  - 1 \frac{2}{3}  \\  = \frac{33}{6}  -  \frac{10}{6}  \\  =  \frac{13}{6}  \\  = 2 \frac{1}{6}

<h2>2</h2>

4 \frac{2}{9}  - 3 \frac{1}{3}  \\  =  \frac{38}{9}  -  \frac{30}{9}  \\  =  \frac{8}{9}

<h2>3</h2>

8 - 3 \frac{2}{7}  \\  =  \frac{56}{7}  -  \frac{23}{7}  \\  =  \frac{33}{7}  \\  = 4 \frac{5}{7}

<h2>4</h2>

7 \frac{2}{5}  - 2 \frac{1}{2}  \\  =  \frac{74}{10}  -  \frac{25}{10} \\ =  \frac{49}{10}  \\  = 4 \frac{9}{10}

skelet666 [1.2K]
We have x + y = 140 degrees and x = 5y - 13 ;
Then, 5y - 13 + y = 140;
6y - 13 = 140;
6y = 153;
y = 153 ÷ 6;
y = 25.5 degrees;
x = 140 - 25.5;
x = 114.5 degrees;

Help me with #4
Sladkaya [172]

Step-by-step explanation:

a. lim(x→2) [g(x) + h(x)]

Use additive property of limits.

= lim(x→2) g(x) + lim(x→2) h(x)

= 0 + 5

= 5

b. lim(x→2) [3 h(x)]

Use multiplication property of limits.

= [lim(x→2) 3] [lim(x→2) h(x)]

= 3 lim(x→2) h(x)

= 3 (5)

= 15

c. lim(x→2) [g(x) h(x)]

Use multiplication property of limits.

= [lim(x→2) g(x)] [lim(x→2) h(x)]

= (0) (5)

= 0
