Like terms are a number that have the same variable (ex. a, b, etc.) and the same exponent. on number one, 11 & 9 are like terms so 11+9=20. number one is 20-2e

1/64. Because 2 raised to the -6 power is 1/64 and its in fraction form. It wouldn’t be -12 because you do Not multiply 2 and -6 together. It wouldn’t be -64 or 1/16 either.

I have 25 red and white marbles in my pocket. If the ratio red to white is 2:3, how many white marbles do I have?
torisob [31]

Answer:

we have 10 red marbles and 15 white marbles

Step-by-step explanation:

<u>Step 1:</u> Given data

Total marbles = 25

Ratio red: white = 2:3

<u>Step 2:</u> Write an equation

Red marbles = X

White marbles = Y

X+ Y = 25

X = 2/3 Y

2/3 Y + Y = 25

5/3 Y = 25

Y = 15

X =2/3 * 15 = 10

To control this we can plug this in the equation X + Y = 25

10 + 15 = 25

10/15 = 2/3

This means we have 10 red marbles and 15 white marbles

Please help me with this math problem.
Shalnov [3]

Answer:

y - 5 = \frac{5}{4} (x - 1).

Step-by-step explanation:

The relation between variable x and y is linear as the increase of y with respect to x is uniform.

That means the slope of the graph obtained from plotting the points on the coordinate plane is constant and it can be obtained by taking any two pairs of points.

Now, the equation of this straight line graph can be obtained from any two pairs of the given points.

Let us assume the points are (1,5) and (5,10)

Therefore, the required equation of the straight line is  

\frac{y - 10}{10 - 5} = \frac{x - 5}{5 - 1}

⇒ y - 10 = \frac{5}{4} (x - 5)

⇒ y - 10 = \frac{5}{4}x - \frac{25}{4}

⇒ y - 5 = \frac{5}{4} x + 5  - \frac{25}{4}

⇒ y - 5 = \frac{5}{4} (x - 1). (Answer)
