∠A and \angle B∠B are supplementary angles. If m\angle A=(4x-30)^{\circ}∠A=(4x−30)

and m\angle B=(4x-14)^{\circ}∠B=(4x−14)

, then find the measure of \angle A∠A.

Answers

Answer 1

Answer:

the measure of ∠A. is 87∘

Step-by-step explanation:

Two angles are said to be supplementary angles if the sum of those angles is 180 degrees.

_________________________________________________

Given

∠A=(4x−30) ∘

∠B=(4x−14) ∘

Fir angles to be supplementary

∠A + ∠B = 180

(4x−30) ∘ + (4x−14) ∘ = 180∘

(8x -54 )∘ = 180∘

=> 8x =  180∘ +  54∘= 234∘

=> x = 234∘/8 = 29.25∘

Thus,

∠A=(4x−30) ∘

∠A=(4*29.25−30) ∘ =( 117 - 30 ) ∘ = 87∘

Thus,

the measure of ∠A. is 87∘

Answer:

x = 2

Step-by-step explanation:

six times a number decreased by 8 is less than five times the number plus 21

Answers

Answer:

6 ( or any number that isn't a common multiple of 5 and 6 ) you should probably double-check just in case.

Step-by-step explanation:

Question = 6x - 8 < 5x +21

so we know that the product of 6x must be divisible by 6 and 5x must be devisable by 5.  so the first factor of 6 is 6 so:

(6 x 6) - 8 < (5 x 6) + 21

36 - 8 < 30 + 21

28 < 51

so x = 6

Honestly, any number would work because 6x is obviously more than 5x, but since for 6x you subtracting 8 and for 5x you adding 21 the answer will always be 6x - 8 < 5x + 21. Unless you use a common multiple of 6 and 5 as your x because then six times that number will always be more than 5 times that number. So for example 30 is a common multiple of 6 and 5 so:

(6 x 30) - 8 is more than (5 x 30) + 21

180 - 8 is more than 150 + 21

172 is more than 171

hope that helps  : )

Representing the problem using mathematical equation, the inequality which represents the scenario is n < 29

Let the number be represented as n :

6n - 8 < 5n + 21

We can then solve for n

6n - 5n < 21 + 8

n < 29

Therefore, the inequality expression which represents the possible values of n for which the expression is true is n < 29

At the supermarket, you can fill your own honey bear container. A customer buys 12 oz of honey for $5.40.
How much does honey cost per ounce?
How much honey can you buy per dollar? Round to the nearest hundredth.

Answers

Answer: a. $0.45; b. 2.22 oz

Step-by-step explanation:

From the question, we are informed that acustomer buys 12 oz of honey for $5.40.

a. How much does honey cost per ounce?

To calculate this, we divide $5.40 by 12oz. This will be:

= $5.40/12

= $0.45

b. How much honey can you buy per dollar?

Since 1 ounce cost $0.45, the number of honey that can be bought for $1 will be:

= $1/$0.45

= 2.22 oz
