-4/9x=16/27 alguien que me ayude

Andre45 [30]

<h3>Answer</h3>

First multiply everything by 27

$- \frac{4}{9} x = \frac{16}{27} = \\ 27 \times ( - \frac{4 }{9}x) = 27 \times \frac{16}{27}$

Then approximate the terms with 27 if it's possible (27 and 9) (27 and 27)

$3 \times ( - \frac{4}{1} ) = 16$

So now multiply again

$3 \times ( - 4) = - 12$

And you have

$- 12x = 16$

$x = - \frac{16}{12} = - \frac{4}{3}$

You're welcome if it's right

Answer:

Top question: -7°

Bottom question : 18°

Step-by-step explanation:

Top question:

The base angles of am isosceles triangle are congruent:

x + 46 = 39 because the base angles of an isosceles triangle are congruent

x + 46° = 39°

x = -7°

Bottom question

The missing angle is 3x because the base angles are congruent

To find the value of x, we must add all the angles inside the triangle, and find the value of x that makes it equal to 180°

3x + 3x + 4x = 180°

10x = 180°

x = 18°

Sorry for the late post!

1 Javier has at most $15.00 to spend today. He buys a bag of pretzels and a bottle of juice for $2.59. If gasoline at this store

Art [367]

Answer:

Javier can buy at maximum about 3.7 gallons of oil.

Step-by-step explanation:

Let g represent the amount of gasoline in galloons.

We know that Javier has at most $15.00 to spend. In other words, the total cost after buying the snacks and gasoline must be less than or equal to 15.

He already bought a snack and a drink for a total of $2.59.

And each gallon of gasoline costs $3.39.

So, we can write the following inequality:

$2.59+3.39g\leq 15.00$

To find how many galloons of gasoline Javier can buy, we will need to solve for g.

So, subtract 2.59 from both sides. This yields:

$3.39g\leq12.41$

Divide both sides by 3.39:

$g\leq3.66$

So, Javier can buy at maximum about 3.7 gallons of oil.

And we're done!

Henry had 20 convertibles and 5 trucks in his miniature car collection. After Henry's aunt bought him some more miniature trucks

saw5 [17]

Answer:

Her aunt buy 75 trucks.

Step-by-step explanation:

Given:

Henry had 20 convertibles and 5 trucks in his miniature car collection. After Henry's aunt bought him some more miniature trucks, Henry noticed that a fifth of his collection were convertible.

Now, to find the trucks her aunt buy.

Let the total collection of Henry be $x.$

Number of trucks Henry had in his collection = 5.

Number of convertibles Henry had in his collection = 20.

As, Henry's $\frac{1}{5}$ collection were convertible.

Now, to get the total number of collection:

$\frac{1}{5}\ of\ x=20.$

$\frac{1}{5} \times x=20$

Multiplying both sides by 20 we get:

$x=100.$

Total collection of Henry = 100.

So, the total number of trucks he had in his collection is:

Total collection of Henry - number of convertibles Henry had in his collection.

$=100-20$

$=80.$

Hence, Henry had total 80 trucks in his collection.

And 5 trucks he had already in his miniature car collection.

Now, to get the number of trucks her aunt buy we subtract trucks he had already in his miniature car collection from the total number of trucks in Henry's collection:

Total number of trucks in Henry's collection - Number of trucks already in his miniature car collection.

$=80-5$

$=75.$

Therefore, her aunt buy 75 trucks.
