3a + 2 - 5a = -14. Can someone solve this for me.

Answers

Answer:

a=8

Step-by-step explanation:

3a + 2 - 5a = -14

Combine like terms

-2a +2 = -14

Subtract 2 from each side

-2a +2-2 = -14-2

-2a = -16

Divide each side by -2

-2a/-2 = -16/-2

a = 8

Answer:

a = 8

Step-by-step explanation:

-2a + 2 = -14

-2a = -16

-16/-2 = 8

a = 8

Is (0,2),(1,4), (2,5), (3,6) a function

Answers

Answer:

This relationship is a function

Step-by-step explanation:

By definition a relation is defined as a function if and only if for each input value x there is only one output value y.

In this case we observe the following ordered pairs

(0,2),(1,4), (2,5), (3,6)

We see that each value x has only a value of y.

x = 0,\ y = 2\n\nx = 1,\ y = 4\n\nx = 2,\ y = 5\n\nx = 3,\ y = 6

Therefore this relationship is a function

What is the value of 2x{6+[12/(3+1)}-1

Answers

The value of an expression is calculated by simplifying the expression.

The value of the expression is 17

The expression is given as:

\mathbf{2 * \{6+[12 / (3+1)\}-1}

Simplify 3 + 1

\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+[12 / 4\}-1}

Divide

\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+[3\}-1}

Remove square bracket

\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{6+3\}-1}

Add

\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * \{9\}-1}

Remove curly bracket

\mathbf{2 * \{6+[12 / (3+1)\}-1 = 2 * 9-1}

Multiply

\mathbf{2 * \{6+[12 / (3+1)\}-1 = 18-1}

Subtract

\mathbf{2 * \{6+[12 / (3+1)\}-1 = 17}

Hence, the value of the expression is 17

Which is greater 1/5 or 1/10

Answers

1/5.  One fifth is equal to 0.2,  while 1/10 is 0.1
1/5 would be greater. Say you had two pizzas both the same size one was cut into five slices the other cut into ten the pizza only cut into five slices would give you the larger slices.

How do you figure this out

Answers

I'm not sure if you're looking for a percentage or a decimal, but to find the answer you just need to do 160 รท 16 = 10. This means that, if you want it as a fraction, the answer is 1/10, and if you want it as a percentage, the answer is 10%. I hope this helps!
