To divide 1/2 by 4, you can treat it as (1/2)/(4/1), and to divide fractions you flip the second fraction and multiply, so:

(1/2)*(1/4)=1/8
So each portion of chocolate was 1/8 pounds.

2 3/10 x-5/7 y-4 5/6 y-2 4/5 x

Stels [109]

Answer: im pretty sure this is correct

- 1/42 x (21x233y)

Step-by-step explanation:

first convert the expressions (2 3/10x x5/7 x y-2 4/5 x x )

then factor the expression (23/10 x- 5/7 y- 29/6 y- 14/5x )

then collect like terms (1/210 x 483 x - 150 y - 1015 - 588x)

factor the expression (1/210 x 105x 1165y)

Multiply reduce (1/210 x -5 (21x + 233y ))

= -1/42 x (21x233y)

Jordan has $40 to spend at the yard sale. He buys 6 books for $2 each. He would like to spend the rest of his money on model car

Deffense [45]

Answer:

He can buy 4 model cars

Step-by-step explanation:

∵ His total money = the cost of books + the cost of model cars

∵ He buys 6 books and the price of each book is $2

∵ The cost of each model car is $7 , let the number of model cars is c

∵ He has $40

∴ 6 × 2 + 7 × c = 40

∴12 + 7c = 40

∴ 7c = 40 - 12 = 28

∴ c = 28/7 = 4

∴ He can buy 4 model cars

Which function best fits the following points?

Goryan [66]

Given:

The graph of a scatter plot.

To find:

The function that best fits the given points.

Solution:

From the given graph it is clear that the linear function is the best fit for the given points because the points lie on a straight line or near to it.

So, options B and C are incorrect because they represent exponential and quadratic function respectively.

Let as assume the two points on the graph are (0.80,-12.82) and (2,-12.79).

Using this two points, the equation of line is:

$y-(-12.82)=\dfrac{-12.79-(-12.82)}{2-0.80}(x-0.80)$

$y+12.82=\dfrac{-12.79+12.82}{2-0.80}(x-0.80)$

$y+12.82=0.025(x-0.80)$

$y+12.82=0.025x-0.02$

$y=0.025x-0.02-12.82$

$y=0.025x-12.84$

$y=-12.84+0.025x$

It is the approximate function to the function that is in option A.

Therefore, the correct option is A.

Y + 5x = 37<br> y = -x+13<br> Show your work<br> Substitution one equation

lukranit [14]

Answer:

x= 6

Step-by-step explanation:

In substitution, replace the y in the first equation with what y equals. In this case, y= -x+13.

-x+13 +5x= 37

4x+ 13= 37

4x= 24

x= 6

Explanation: First combination like terms, -x and 5. 5x-1x = 4x. Next, follow the opposite of PEMDAS. Adding and subtracting are last, so subtract the 13 on each side. All that's left is dividing the 4 on each side, and you're left with 6.
