WITCHER [35]

The team won 4 gold medals, 4 silver medals and 10 bronze medals.

Step-by-step explanation:

Given,

Total medals won = 18

Ratio of gold, silver and bronze = 2:2:5

Let,

x be the original number.

Therefore,

Gold medals = 2x

Silver medals = 2x

Bronze medals = 5x

According to given statement;

$2x+2x+5x=18\\9x=18$

Dividing both sides by 9

$\frac{9x}{9}=\frac{18}{9}\\x=2$

Gold medals = 2x = 2(2) = 4

Silver medals = 2x = 2(2) = 4

Bronze medals = 5x = 5(2) = 10

The team won 4 gold medals, 4 silver medals and 10 bronze medals.

Which of the following inequalities have the same solution set? Select all that apply (>= means greater than or equal to and

Alex_Xolod [135]

<span>7n + 4 - 5n <= 2(n+2) Let's simplify these expression first 2n + 4 <= 2(n + 2) 2(n +4) = 2n + 4 The LHS and RHS expressions are the same but the inequality says contrary Hence 2n + 4 is not less than but equal to 2(n + 2). 7+ 6a >= -4(2-a) - 2a -4(2-a) - 2a = -8 + 4a - 2a = -8 + 2a. It should be obvious that 7 +6a is greater than the RHS expression. Suppose a= 2 then we have 7 + 6(2) = 19 while -8 + 2(2) = - 8 + 4 = -4 So it follows that 7 + 6a >= -4(2-4) -2a 4x >= 8. The expression is always true so the equal to option is out.</span>

Logarithms- How to answer these questions?

kotykmax [81]

Answer:

2. m = b³ (= 216)

3. logp(x) = -4

Step-by-step explanation:

2. The given equation can be written using the change of base formula as ...

... log(m)/log(b) + 9·log(b)/log(m) = 6

If we define x = log(m)/log(b), then this becomes ...

... x + 9/x = 6

Subtracting 6 and multiplying by x gives ...

... x² -6x +9 = 0

... (x -3)² = 0 . . . . . factored

... x = 3 . . . . . . . . . value of x that makes it true

Remembering that x = log(m)/log(b), this means

... 3 = log(m)/log(b)

... 3·log(b) = log(m) . . . . . multiply by the denominator; next, take the antilog

... m = b³ . . . . . . the expression you're looking for

___

3. Substituting the given expression for y, the equation becomes ...

... logp(x^2·(p^5)^3) = 7

... logp(x^2) + logp(p^15) = 7 . . . . . use the rule for log of a product

... 2logp(x) + 15 = 7 . . . . . . . . . . . . . use the definition of a logarithm

... 2logp(x) = -8 . . . . . . . . . . . . . . . . subtract 15

... logp(x) = -4 . . . . . . divide by 2
