The one with the word bank is in this order, right angle, acute angle, straight angle and then obtuse then you try to guess an estimate a right angle is always a 90 degree angle and a straight angle is always 180 degrees the given part of the angle would be subtracted by 180 for example 180-130 which means X= 50 degrees

Match each expression to another expression with the same value. 24 ÷ 3 53 × 7 56 − 21 4 − 3 40 × 2 8 × 50 8 × (5 × 12 − 10) (8

FrozenT [24]

Answer:

a. 24 ÷ 3 = 8 ⇒ i. 8 × 3 ÷ (6 − 3) = 8

b. 53 × 7 = 371 ⇒ h. (8 × 7 − 3) × 7 = 371

g. 8 × (5 × 12 − 10) = 400 ⇒ f. 8 × 50 = 400

Step-by-step explanation:

Given:

We have to match the equivalent expressions:

a. 24 ÷ 3 f. 8 × 50

b. 53 × 7 g. 8 × (5 × 12 − 10)

c. 56 − 21 h. (8 × 7 − 3) × 7

d. 4 − 3 i. 8 × 3 ÷ (6 − 3)

e. 40 × 2

Solution:

a. 24 ÷ 3 = 8

b. 53 × 7 = 371

c. 56 − 21 = 35

d. 4 − 3 = 1

e. 40 × 2 =80

f. 8 × 50 = 400

g. 8 × (5 × 12 − 10) <em>Using PEMDAS rule.</em>

⇒ $8\times (60-10)$

⇒ $8\times 50$

⇒ $400$

h. (8 × 7 − 3) × 7

⇒ $(56-3)\times 7$

⇒ $(53)\times 7$

⇒ $371$

i. 8 × 3 ÷ (6 − 3) = 8

⇒ $\frac{8\times 3}{3}$

⇒ $\frac{24}{3}$

⇒ $8$

Answers:

a. 24 ÷ 3 = 8 ⇒ i. 8 × 3 ÷ (6 − 3) = 8

b. 53 × 7 = 371 ⇒ h. (8 × 7 − 3) × 7 = 371

g. 8 × (5 × 12 − 10) = 400 ⇒ f. 8 × 50 = 400

c,d and e didn't have any match

a is equivalent to i,b equivalent to h and g is equivalent to f.

Find the degree of the monomial.<br> 4b3c6

Bingel [31]

Answer:

Well it would be 1 if 4b3c6 is what is actually given, but if it was (4b^3)(c^6) it would be 6 or if it was (4b)(3c^6), it'd still be 6

Angelo drew a scale model of the flagpole at school. If the actual pole is 15 feet tall, and his drawing is 10 inches tall, what

Darya [45]

Answer: $\frac{2}{3}$

Step-by-step explanation:

Given

Angelo drew a model with his drawing length 10 inches tall

The actual pole length is 15 feet tall

drawing scale is the ratio of drawing length to the actual length i.e.

$\Rightarrow \text{Scale used l=}\dfrac{10}{15}\\\\\Rightarrow l=\dfrac{2}{3}$
