Answer:

El valor de x en esta ecuación es -1.

Step-by-step explanation:

4x - 8 + 9 - 6x = 3x + 6

En primer lugar, combinar términos similares en cada lado de la ecuación.

-2x + 1 = 3x + 6

A continuación, resta 3 veces en ambos lados de la ecuación.

-5x + 1 = 6

Ahora, resta 1 de ambos lados de la ecuación.

-5x = 5

Por último, divida por -5 en ambos lados de la ecuación.

x = -1

Right triangle ABC is similar to right triangle DEF. If the side lengths for triangle ABC are 15, 20, 25, respectively, which va

solniwko [45]

Answer:

$A = 15$ $B = 20$ $C = 25$

$D = 30$ $E = 40$ $F = 50$

$D = 3$ $E = 4$ $F = 5$

Step-by-step explanation:

Given

Similar Triangles: ABC and DEF

$A = 15$

$B = 20$

$C = 25$

Required

Determine the sides of DEF

No options were given, so I will solve on a general terms.

Since both triangles are similar, then the following relationship exists.

DEF = ABC * n

i.e.

$D = A * n$ $E = B * n$ $F = C * n$

Where

$n = Scale\ Factor$

Assume n = 2.

So, we have:

$D = A * n$

$D =15 *2$

$D = 30$

$E = B * n$

$E = 20 * 2$

$E = 40$

$F = C * n$

$F = 25 * 2$

$F = 50$

Assume $n = \frac{1}{5}.$

So, we have:

$D = A * n$

$D =15 *\frac{1}{5}$

$D = 3$

$E = B * n$

$E = 20 * \frac{1}{5}$

$E = 4$

$F = C * n$

$F = 25 * \frac{1}{5}$

$F = 5$

So, the possible sides are:

$A = 15$ $B = 20$ $C = 25$

$D = 30$ $E = 40$ $F = 50$

$D = 3$ $E = 4$ $F = 5$

A stack of round crackers are in the shape of an oblique cylinder. The diameter of each cracker is 6 centimeters and the height

tekilochka [14]

Answer: 294cm

Step-by-step explanation:

The volume of a oblique cylinder is given by:

Volume= πr^2h

where

π = 3.14

r = radius

h = height

Radius= diameter/2 = 6/2 = 3

We have all the values, so we put it in the formulae so we can get the answer.

Volume= πr^2h

= 3.14 × 3 × 3 × (0.4 × 26)

= 294cm

Winnie adds the smallest 30 positive even numbers. Grogg adds the largest 30 odd negative numbers. How much greater is Winnie's

MaRussiya [10]

Answer:

1830

Step-by-step explanation:

Sum of smallest 30 positive even numbers is given by

2 + 4 + 6 + 8 + ......... up to 30 terms

= 2 ( 1 + 2 + 3 + 4 + ....... + 30)

= $2 \times \frac{1}{2} \times (30) \times (30+1) = 930$

Again the sum of largest 30 odd negative numbers is given by

- 1 - 3 - 5 - 7 - ...... up to 30 terms.

= - (1 + 3 + 5 + 7 + ...... up to 30 terms)

{This is an A.P. series having first term 1, common difference 2 and the number of terms 30}

= $-\frac{30}{2} [2 \times 1 + (30-1) \times 2]$

= - 900

Now, Winnie has the sum 930 and Grogg has the sum - 900.

So, Winnie's sum is (930 + 900) = 1830 more than Grogg's sum. (Answer)
