Mathematics

Alik [6]3 years ago
8 0

Answer:

B, the second one.

Step-by-step explanation:

Take the equation, y=2x+1. 1 is the y-intercept, so that automatically eliminates some potential answer choices. Your slope is 2/1,  so you would use rise over run to find the correct answer choice.

Answer:

Product means to multiply.

No more than 30 is basically it can be 30 OR less nothing more.
k(-5) ≤ 30
Thats your inequality.

Solution is easy.
-5k ≤ 30
Divide -5
k ≥ 6
k ≥ 6 since when you divide or multiply by a negative number the inequality is flipped.

k≥ 6 is your solution .

Identify the lengths of QS and SR
Semenov [28]
<span>The bisector of an angle of a triangle divides the opposite side into segments that are proportional to the adjacent sides  </span>⇒
<span>
10/12 = (3x+2)/(5x-0.4)
10(5x-0.4) = 12(3x+2)
50x - 4 = 36x + 24
50x - 36x = 24 + 4
14x = 28
x = 28/14
x = 2

QS = 3x + 2 = 3*2 + 2 = 6 + 2 = 8 
SR = 5x - 0.4 = 5*2 - 0.4 = 10 - 0.4 = 9.6

Answer is QS=8, SR=9.6

The average weight of 3 men a, b and c is 84 kg. another man d joins the group and the average now becomes 80 kg. if another man
Alenkasestr [34]

The weight of A is 75kg.

<h3>How to calculate the weight?</h3>

Total weight of A + B + C = 84 x 3 = 252kg

Total weight of A + B + C + D = 80 x 4 =.320 kg

Weight of D = 320 - 252 = 68 kg

Given, E = D + 3 = (68 + 3) kg = 71 kg

Total weight of B + C + D + E = (79 x 4) = 316 kg

Weight of B + C = 316 kg - 71 kg - 68 kg = 177 kg

Weight of A only will be:

= 320 kg - 177 kg - 68 kg

= 75 kg
