Hey there!

Let's think of what 1000x means.

We know that multiplication is repeated addition. For example, 5(5) = 5+5+5+5+5. It's 5 added five times.

It's no different here. That means we have x 1000 times. If we look at a simpler situation:

5x - 3x, we have (x + x + x + x + x) - (x + x + x)

That means we're getting rid of 3 x's, which means we have 2x. If we have different coefficients but the same variable, we can just subtract or add the coefficients but keep the variable. That means:

4x - 2x = 2x and 10x - 5x = 5x

Now, we can do this problem. We want:

(1000-1)x = 999x

Your answer is D.

Hope this helps!

Zepler [3.9K]

Answer:

5 milk shakes

From the above question, we know that for the recipe

1/3 cup of milk = 1 milk shake

15/8 cup of milk = y milk shakes

We cross Multiply

15/8 cup × 1 = 1/3cup × y

y = 15/8 cup × 1 /1/3cup

= 15/8 ÷ 1/3

= 15/8 × 3

A bean plant grows at a constant rate for a month. After 10 days, the plant is
777dan777 [17]

Answer:

B. y - 35 = 2(x - 10)

Step-by-step explanation:

The height of the plant, y, after x days could be modeled by the equation

<h3>y-y0=k(x-xo)     (1),</h3><h3>where y0 was the initial height at 'x0'th. day, and k is the constant of proportionality.</h3><h3>From equation (1), k could be evaluated as follows:</h3><h3>k=(y-y0)/(x-x0) </h3><h3>From the problem statement, we may determine k by plugging in the given values, e.g. y0= 35, x0=10, y=55, x=20.</h3><h3>Thus,</h3><h3>k=(55-35)/(20-10)=2</h3><h3>Therefore, the model equation becomes</h3><h3>y-35=2(x-10)</h3><h3></h3>

x = 75°

Sum of angles in a triangle: 180°

So,

50°+55°+x=180°

105°+ x = 180°

Subtract 105° from both sides

x = 75°
