inna [77]

Answer:

∠ A = 48°

Step-by-step explanation:

Supplementary angles are those angles that measure up to 180 degrees.

∠A and ∠B are supplementary angles. If m ∠ A = ( 4 x − 16 ) ∘ and m ∠ B = ( 8 x + 4 ) ∘,then find the measure of ∠ A

Step 1

∠A + ∠B = 180°

(4x−16)° + (8x+4)° = 180

4x - 16 + 8x + 4 = 180

12x -12 = 180

12x = 180 + 12

12x = 192

x = 192/12

x = 16

Step 2

To find the measure of ∠ A

∠ A = 4x - 16

= 4 × 16 - 16

= 64 - 16

= 48°

Therefore,

∠ A = 48°

KatRina [158]

Let D be dogs and C be cats

<em>dogs, d, is initially five less than twice the number of cats, c</em>

D + 5 = 2C

<em>If she decides to add three more of each, the ratio  of cats to dogs will be</em>

D + 8 = 2C + 3

<em>Could Bea's Pet Shop initially have 15 cats and 20 dogs?</em>

Simply plug in the numbers

20 + 5 = 2(15)

This is clearly not true: 25 does not equal 30

WARRIOR [948]

Answer:

The answer is below

Step-by-step explanation:

Given the time taken to answer each multiple choice question as one minute, the time taken to x multiple choice question = 1 minute/question × x questions = x minutes

Given the time taken to answer each essay question as six minute, the time taken to y essay question = 6 minute/question × y questions = 6y minutes

Therefore the total time taken to complete X multiple choice question and y essay questions = the time taken to x multiple choice question + the time taken to y essay question = x + 6y
