solve with substitution 3x + y =19 -6x - 5 = y​

Answer:

1

Step-by-step explanation:

As we know that addition and subtraction are inverse operations, as are multiplication and division.

The given equation is c+3=4

To solve such equations we isolate the unknown( to keep it either to the left or right of = sign) as c = 4-3  

This is also called transposing and the sign of the transposed value changes.

Hence, c = 4-3 = 1

Answer:

Random sample of 500 residents of Story County

Step-by-step explanation:

SAMPLE can be defined as the process in which some group of people are randomly selected from a large population for the sole aim of carrying out statistical analysis that will represent the whole population at large instead of carryingout the SAMPLE on each person.

Therefore based on the information given the best description of the SAMPLE will be the 500 RESIDENT OF STORY COUNTY reason been that we were told that a random SAMPLE of the 500 residents of Story County were collected which in turn represent 80,000 of the residents of Story County at large.

Answer:

A

Step-by-step explanation:

if x=19, 19x3 =57 and 57+123=180 and straight angle = 180 so A

Answer:

X=19

Step-by-step explanation:

123 and 3x are supplementary/they equal 180 added together.

Let's solve your equation step-by-step.

123+3x=180

Step 1: Simplify both sides of the equation.

3x+123=180

Step 2: Subtract 123 from both sides.

3x+123−123=180−123

3x=57

Step 3: Divide both sides by 3.

3x/3 = 57/3

x=19

Answer:

- 2.18

Step-by-step explanation:

550 × [tex]3^{x}[/tex] = 50

[tex]3^{x}[/tex] = [tex]\frac{1}{11}[/tex]

[tex]log_{3}[/tex] [tex]\frac{1}{11}[/tex] = x

x = [tex]log_{3}[/tex] 1 - [tex]log_{3}[/tex] 11

[tex]log_{3}[/tex] 1 = 0

[tex]log_{3}[/tex] 11 = 2.1826583386

x ≈ - 2.18

Answer:

[tex]m > 1.75[/tex]

Step-by-step explanation:

1) Add 0.3 to both sides.

[tex]m > 1.45 + 0.3[/tex]

2) Simplify 1.45 + 0.3 to 1.75.

[tex]m > 1.75[/tex]

Therefor, the answer is m > 1.75.

Answer:

184

Step-by-step explanation:

here's your solution

=> first term = 4 = a

=> common difference = 2 = d

=> formula = a + (n - 1) d

=> putting the value of variable

=> 4 + (91 - 1)* 2

=> 4 + (90 * 2)

=> 4 + 180

=> 184

Answer:

Slope is -3

Equation is y = -3x + 2

Step-by-step explanation:

(0 , 2) and ( -1 , 5)

m= (y2-y1)/(x2-x1)

m= (5 - 2)/(-1 -0)

m= 3/-1

m= -3

y - y1 = m(x - x1)

y - 2 = -3(x - 0)

y - 2 = -3x + 0

y = -3x + 2

Respuesta:

183x + 356y = 3763

Explicación paso a paso:

Dejar :

Número de kilos de papel = x; número de kilos de cartón = y

Kilo de papel = 183; kilo de cartón = 356

Cantidad total ganada = 3763

(Costo por kilo de papel * número de kilos de papel) + (costo de kilos de cartón * número de kilos de cartón)

(183 * x) + (356 * y) = 3763

183x + 356y = 3763

Find the surface area of the cylinder!

Equation =

(2 × 3.14 × 10) × (10 + 7) =

62.8 × 17 ≈

The surface area of the cylinder ≈ 1067.6 square metres

Answer:

Use this formula to calculate for the surface area of cylinder.

Step-by-step explanation:

A=2π r h+2 π r^2.

use r = 10 m and h = 7 m

2 (3.14) (10) 7 + 2 (3.14) 10 ^2. = 439.6 + 628 = 1067.6

round to the nearest hundredths = 1068
