Answer: 6

Step-by-step explanation:

4+(9 x 2) / (4-1)-4=6

Calculate within parentheses (9 x 2) : 18

= 4+18 / (4-1) -4

Calculate within parentheses (4-1) : 3

=4+8 / 3-4

Multiply and divide (Left to right) 18 / 3 : 6

= 4+6-4

Add and subtract (left to right) 4+6-4 : 6

Answer:

Step-by-step explanation:

Use PEMDAS

P = parenthesis

E = Exponents

M = Multiplication*

D = Division*

A = Addition**

S = Subtraction**

*either can come first, it just depends which comes first in the equation.

**either can come first, it just depends which comes first in the equation.

Step 1 : Write equation 4( 9 × 2 ) ÷ ( 4 -1 ) - 4

Step 2: Solve in parenthesis 4(18) ÷ (3) - 4

Step 3: Solve multiplication  72 ÷ 3 - 4

Step 4: Solve division 24 - 4

Step 5 : Solve subtraction 20

URGENT HELP NEEDED WITH TRIANGLES/CIRCLES! IF ET = 31, DE = 65, AND DC= 74, FIND THE PERIMETER OF DCE.

snow_tiger [21]

ES = ET

and

DS = DR

and

CR = CT ( because each pair are tangents to the circle)

So ES = 31 and Ds = 65-31 = 34

and DR = 34 and CR = 74- 34 = 40.

CT = CR = 40

Therfore the line EC = 31 + 40 = 71

Finally the perimeter = 65 + 74 + 71 = 210 (answer)

Consider the following IP problem:

Liono4ka [1.6K]

Answer:

$(3,0)$

Step-by-step explanation:

The integer points which fall in the common region bounded by the lines are

$(0,2),(2,3),(3,0)$

Since, one of the points is $(2.22...,3.11....)$ we round it to $(2,3)$

If we round up then the point will be $(3,4)$ which does not fall in the bounded region.

Also $x_1\geq 0$ and $x_2\geq 0$ no negative values are considered.

Applying in the values in the LP problem $Z=5x_1+x_2$

$Z=5\times 0+2\\\Rightarrow Z=2$

$Z=5\times 2+3\\\Rightarrow Z=13$

$Z=5\times 3+0\\\Rightarrow Z=15$

So, the LP problem is maximum at point $(3,0)$ .
