2/5(10+x)

2.5+x

x=2.5

We can solve this problem by setting up a proportion. When creating the proportion it is important to keep the units aligned. Our proportion would look like this: 

\frac{10}{25} =  \frac{x}{40}

We are looking for x, the amount of sugar she needs with 40% sugar syrup. To solve, we can cross multiply and divide. We cross multiply 10 x 40, then divide by 25: 

10 x 40 = 400
400/25 = 16

Ms. Maryna needs 16 lbs of sugar to make 40% sugar syrup.

Use linear regression to find a

A function that fits the following points (0,5), (2,-13) is y = 9x + 5

<h3>Equation of a line</h3>

The equation of a line in slope-intercept form is expressed as;

y =mx +b

where;

m is the slope

b is the intercept

Given the following coordinates (0,5), (2,-13)

Slope = -13-5/2-0
Slope = -18/-2

Slope = 9

Since the y-intercept is b = 5, hence the equation of the line will be y = 9x + 5

Answer:

Hexagonal prism

Step-by-step explanation:

Since the base is a hexagon (six sided shape) and there are two of them, it is considered a prism. This is an Hexagonal prism.

Do not confuse it with hexagonal pyramid because:

1) It does not look like a pyramid

2) It only has one base

If x=10, write an expression in terms of x for the number 5,364
LenKa [72]

Answer:

(5,354 + x)

or

536.4*x

Step-by-step explanation:

We know that x = 10.

Now we want to write an expression (in terms of x) for the number 5,364.

This could be really trivial, remember that x = 10.

Then:  (x - 10) = 0

And if we add zero to a number, the result is the same number, then if we add this to 5,364 the number does not change.

5,364 = 5,364 + (x - 10) = 5,364 + x - 10

5,364 = 5,354 + x

So (5,354 + x) is a expression for the number 5,364 in terms of x.

Of course, this is a really simple example, we could do a more complex case if we know that:

x/10 = 1

And the product between any real number and 1 is the same number.

Then:

(5,364)*(x/10) = 5,364

(5,364/10)*x = 5,364

536.4*x = 5,364

So we just found another expression for the number 5,364 in terms of x.

Simplify the following expression by combining like terms.
Aleks04 [339]

Answer:

8x^2+3x

Step-by-step explanation:

What I read is 2x+8x^2-4x+5x

combining like terms means putting the terms that have the same variable part together

8x^2 is the only one that doesn't have any terms like it as far as the variable part

so 8x^2+2x-4x+5x

We just need to figure out 2-4+5 which is -2+5=3

So the answer is 8x^2+3x
