Answer:

a=0.2b

Step-by-step explanation:

Simplifying

(3a + -1b) + 2a = 0

Remove parenthesis around (3a + -1b)

3a + -1b + 2a = 0

Reorder the terms:

3a + 2a + -1b = 0

Combine like terms: 3a + 2a = 5a

5a + -1b = 0

Solving

5a + -1b = 0

Solving for variable 'a'.

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

Add 'b' to each side of the equation.

5a + -1b + b = 0 + b

Combine like terms: -1b + b = 0

5a + 0 = 0 + b

5a = 0 + b

Remove the zero:

5a = b

Divide each side by '5'.

a = 0.2b

Simplifying

a = 0.2b

The equation below represents the trend line of a scatter plot showing the hours spent studying versus science test scores.
navik [9.2K]

Answer:

On the science test  the point  ( 0 , 424 ) the intercepts is bigger

Step-by-step explanation:

The relation hours spend vs science test score is

y  =  6.5*x  + 424

And the relation hours spend vs Maths test score is

y  =  7.2*x   + 34.7

Making   x =  0  ( student does not study at all ) we get:

For science score test woul be

y  =  0  + 424

In case of maths

y  =  0  + 34.7

That mean student without studying will get better score in science.

The point  ( 0 , 424)   ( science ) represents the interception with y axis

in Maths case such point is  ( 0 . 34.7)

dwight bought 10 acres of land and built a house on 2.0 acres. dwight wanted to plant beets on the remaining 8.0 acres. if it ta
aleksklad [387]

Using mathematical operations and unit conversions, the number of beets that Dwight can grow on the 8 acres is <u>3,885 beets</u>.

<h3>What are mathematical operations?</h3>

Mathematical operations include the use of basic math operators to calculate the values of mathematical statements.

The math operators include addition, multiplication, division, subtraction, exponentiation, and modulus.

<h3>Data and Calculations:</h3>

The measurement of the land = 10 acres

The measurement of the house on the land = 2 acres

The remaining space on the land = 8 acres

The number of beets on 1/8 (0.125) hectare = 150 beets

1 hectare = 2.47105 acres

8 acres = 3.23749 hectares (8/2.47105)

If 0.125 hectares = 150 beets

3.23749 hectares = 150/0.125 x 3.23749

= 3,885 beets

Thus, the number of beets that Dwight can grow on the 8 acres is <u>3,885 beets</u>.
