Answer:

x = 42.9 m

Step-by-step explanation:

Corresponding sides of similar triangles MAB and MNP are proportional. This means ...

x/MP = MA/MN

However, we don't have a number for MA yet, so we need to find it.

MA +AN = MN

MA = MN - AN subtract AN

MA = 67.2 m - 32 m = 35.2 m

Now, we can use this to find x.

x = MP · (MA/MN) = (81.9 m) · 35.2/67.2

x = 42.9 m

How many times can a nine go into a 20

PolarNik [594]

A nine can go into a 20 two whole times. After that, there's still
some room left in the 20, but it's only enough room for a 2.

Which is bigger 1/3 or 3/5

GuDViN [60]

Answer: 3/5

Step-by-step explanation: Notice that the fractions that we are comparing in this problem have different denominators. When fractions have different denominators, they are called unlike fractions.

To compare unlike fractions, we must first get a common denominator. The common denominator of 3 and 5 will be the least common multiple of 3 and 5 or 15.

To get a 15 in the denominator of 1/3, we multiply the numerator and the denominator by 5 which gives us 5/15.

To get a 15 in the denominator of 3/5, we multiply the numerator and the denominator by 3 which gives us 9/15.

Notice that we now have like fractions since both fractions have a 15 in the denominator.

To compare like fractions, we simply look at the numerators.

9/15 - 5/15

Since 9 is greater than 5, 9/15 is greater than 5/15.

This means that 3/5 is bigger than 1/3.

GrogVix [38]

<em>7 grams of sugar</em>

<h2>Explanation:</h2>

________________________________________

I'll assume your answer is as follows:

<em>A bowl of cereal had 3 3/6 grams of sugar in it. If Victor ate 2 bowl a week, how many grams of sugar would he have eaten?</em>

________________________________________

If so, then we know that:

A bowl of cereal had 3 3/6 grams of sugar in it.

Victor ate 2 bowl a week

In other words, the total of sugar he ate can be calculated as:

$3\frac{3}{6}\times2 \\ \\ Converting \ mixed \ fraction \ into \ improper \ fraction: \\ \\ =(3+\frac{3}{6})\times2 \\ \\ =(\frac{3(6)+3}{6})\times 2 \\ \\ =(\frac{21}{6})\times 2 \\ \\ =(\frac{7}{2})\times 2 \\ \\ =7$

So <em>he'd have eaten 7 grams of sugar</em>

Answer:

x = 2

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

Brackets

Exponents
Multiplication
Division

Left to Right

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

0.4(12 - 3x) = 0.3(12x - 16)

<u>Step 2: Solve for </u><em><u>x</u></em>

Distribute: 4.8 - 1.2x = 3.6x - 4.8
Add 1.2x on both sides: 4.8 = 4.8x - 4.8
Add 4.8 on both sides: 9.6 = 4.8x
Divide 4.8 on both sides: 2 = x
Rewrite: x = 2
