Estimate 1 7/8 - 1 1/2

Mathematics
1 answer:
OLEGan [10]3 years ago
3 0

Answer:

1⅞ - 1½ ≈ ½

Step-by-step explanation:

Estimation is mental arithmetic. Practice until you can do this in your head.

Here's one way to estimate with mxed numbers.

Step 1. Separate into whole number and fractional parts

1⅞ - 1½ = 1 + ⅞ - 1 - ½

Step 2. Solve the whole number parts

1 - 1 = 0

Step 3. Solve the fraction parts by estimating.

We will round to the nearest ½, so we should round up a number greater than ¾.

(a) ⅞ is greater than ⁶/₈ (¾), so we round it up to ⁸/₈:

⅞ - ½ ≈ ⁸/₈ - ½

(b) Convert each fraction to a common denominator.

We can write ⁸/₈ as ²/₂

⁸/₈ - ½ = ²/₂ - ½

(c) Solve the fraction part

²/₂ - ½ = ½

Step 4. Combine the whole and fraction parts

0 + ½ = ½  

So, 1⅞ - 1½ ≈ ½

X = 2y
2x + 2y = 24
So if x = 2y that means 2x = 4y. Which means that 2x + 2y = 24 can be written as 4y + 2y = 24. Simplified to 6y = 24. Now we need to get 1y so we divide both sides by 6, 6y/6 = y and 24/6 = 4. so y = 4. so x= 2y can be written as x = 8.

Need help with this math.
madreJ [45]

The end behavior of the function y = x² is given as follows:

f(x) -> ∞ as x -> - ∞; f(x) -> ∞ as x -> - ∞.

<h3>How to identify the end behavior of a function?</h3>

The end behavior of a function is given by the limit of f(x) when x goes to both negative and positive infinity.

In this problem, the function is:

y = x².

When x goes to negative infinity, the limit is:

lim x -> - ∞ f(x) = (-∞)² = ∞.

Meaning that the function is increasing at the left corner of it's graph.

When x goes to positive infinity, the limit is:

lim x -> ∞ f(x) = (∞)² = ∞.

Meaning that the function is also increasing at the right corner of it's graph.

Thus the last option is the correct option regarding the end behavior of the function.

<h3>Missing information</h3>

We suppose that the function is y = x².
