Let x be the larger number and y be the smaller number.
Using the given info, we get
x = 4y - 2
We also know that 
x + y = 18
Substitute x = 4y -2 into x + y = 18
(4y -2) +y = 18
5y - 2 = 18
5y = 20
y = 4
Enter this value into x = 4y - 2
x = 4(4) - 2
x = 14
The larger number is 14 and the smaller one is 4.

Evaluate the expression:–|20| + |5|
Svetradugi [14.3K]
-|20| + |5| = -15

Steps:
Apply absolute rule: |a| = a, a >/ 0
|20| = 20
= -20+5
Apply absolute rule: |a| = a, a >/ 0
|5| = 5
= -20+5
Refine 
= -15

Help me with this immediately​
BARSIC [14]

Answer:

complementary angles, x=19

Step-by-step explanation:

since the two parts of the angle add up to 90, they are complementary angles.

you can find x by adding them and setting it equal to 90:

3x-2+2x-3 = 90

5x-5 = 90

5x = 95

x = 19

The edge roughness of slit paper products increases as knife blades wear. Only 1% of products slit with new blades have rough ed
Masteriza [31]

Answer: Our required probability is 2.8%.

Step-by-step explanation:

Since we have given that

Probability of products slit with new blades have rough edges P(X) = 1%

Probability of products slit with blades of average sharpness exhibit roughness P(Y) = 3%

Probability of products slit with worn blades exhibit roughness P(Z) = 5%

Let A be the  selected product that exhibit edge roughness.

P(A|X) = 25% = 0.25

P(A|Y) = 60% = 0.60

P(A|Z) = 15% = 0.15

So, the probability of products that exhibit edge roughness is given by

P(X)P(A|X)+P(Y)P(A|Y)+P(Z)P(A|Z)\\\\=0.01\times 0.25+0.03\times 0.60+0.05\times 0.15\\\\=0.028\\\\=2.8\%

Hence, our required probability is 2.8%.

Determine f(9/2) for the function f(x)=3x-5
ANEK [815]

Answer:

f(9/2) = 17/2

Step-by-step explanation:

f(x) = 3x-5

let x=9/2

f(9/2) = 3*9/2 -5

f(9/2) = 27/2 - 5

get a common denominator

f(9/2) = 27/2 - 10/2

f(9/2) = 17/2
