Question 10 will be posted separately

10 5/24 pizzas

Step-by-step explanation:

2 5/8 + 4 1/3 + 3 1/4

The common denominator is 24

2 5/8 = 2 5/8*3/3 = 2 15/24

4 1/3 *8/8 = 4 8/24

3 1/4 * 6/6 = 3 6 /24

2 15/24 + 4 8/24 + 3 6/24

9 29/24

9 + 24/24 + 5/24

9 + 1 +5/24

10 5/24

10 5/24 pizzas

Step-by-step explanation:

Total pizza = sum of pizzas

= 2⅝ + 4⅓ + 3¼

= (2 + 4 + 3) + (⅝ + ⅓ + ¼)

= 9 + [5(3) + 1(8) + 1(6)]/24

(LCM of 8,3 and 4 is 24)

= 9 + (29/24)

= 9 + 1 5/24

= 10 5/24

idk this answer sorry cant on this one.

step-by-step explanation:

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
