How do you subtract an integer from another integer without using a number line or counters? Give an example.

1 answer:

8 0

If they are two positive numbers, do it normally. If there is a negative and a positive, change it to addition and switch the SECOND integer sign. Only works with two integer…s in a subtraction question.

QUESTION ONE-

Cross multiply:

5 * 15 = 12 * y

Simplifying

5 * 15 = 12 * y

Multiply 5 * 15

75 = 12 * y

Solving

75 = 12y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-12y' to each side of the equation.

75 + -12y = 12y + -12y

Combine like terms: 12y + -12y = 0

75 + -12y = 0

Add '-75' to each side of the equation.

75 + -75 + -12y = 0 + -75

Combine like terms: 75 + -75 = 0

0 + -12y = 0 + -75

-12y = 0 + -75

Combine like terms: 0 + -75 = -75

-12y = -75

Divide each side by '-12'.

y = 6.25

Simplifying

y = 6.25

QUESTION TWO-

Cross multiply:

8 * w = 20 * 6

Simplifying

8 * w = 20 * 6

Multiply 20 * 6

8w = 120

Solving

8w = 120

Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Divide each side by '8'.

w = 15

Simplifying

w = 15

QUESTION 3-

Cross multiply:

s + 1 * 8 = 4 * 4

Simplifying

s + 1 * 8 = 4 * 4

Reorder the terms:

1 + s * 8 = 4 * 4

Reorder the terms for easier multiplication:

8 * 1 + s = 4 * 4

1 * 8 + s * 8 = 4 * 4

8 + 8s = 4 * 4

Multiply 4 * 4

8 + 8s = 16

Solving

8 + 8s = 16

Solving for variable 's'.

Move all terms containing s to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 8s = 16 + -8

Combine like terms: 8 + -8 = 0

0 + 8s = 16 + -8

8s = 16 + -8

Combine like terms: 16 + -8 = 8

8s = 8

Divide each side by '8'.

s = 1

Simplifying

s = 1

Ok, primero haces estas hostilidades de considerable duración y magnitud. En el uso de las ciencias sociales, se agregan ciertas calificaciones. Los sociólogos suelen aplicar el término a tales conflictos sólo si se inician y conducen de acuerdo con formas socialmente reconocidas. Tratan la guerra como una institución reconocida en la costumbre o en la ley. Los escritores militares suelen limitar el término a las hostilidades en las que los grupos contendientes tienen el mismo poder para hacer que el resultado sea incierto durante un tiempo. Los conflictos armados de estados poderosos con pueblos aislados e impotentes suelen denominarse pacificaciones, expediciones militares o exploraciones; con los estados pequeños, se les llama intervenciones o represalias; y con grupos internos, rebeliones o insurrecciones. Tales incidentes, si la resistencia es lo suficientemente fuerte o prolongada, pueden alcanzar una magnitud que les dé derecho al nombre de "guerra".

Solve using elimination<br><br> 2x+5y=34<br> x+2y=14

Darina [25.2K]

2x + 5y = 34

x+2y = 14

Multiply the second equation by two to create like terms for one variable.

2(x+2y = 14)

2x + 4y = 28

2x + 5y = 34

2x + 4y = 28 -- Subtract.

y = 34.28 = 6

Solve for x

x + 2(6) = 14

x + 12 = 14

x = 2

Check:

2 + 2(6) = 14

2 + 12 = 14

14 = 14

Answer:

X = 2

Y = 6
