Answer is D) take 5 blocks away from the left side.

There are 8 blocks on the left and only 3 on the right, 8 - 3 = 5

Since there are 8 block on the left side and 3 on the right side, they have to have the same amount to be equal.

A) 8 = 3 + 3 → 8 = 6? No, this isn't right

B) 8 = 4 + 3 → 8 = 7? Nope

C) 8 - 3 = 3 → 5 = 3? No

D) 8 - 5 = 5 → 3 = 3? Yes, so to balance the two sides you would need to take 5 blocks from the left side (or add 5 to the right side but that isn't a choice)

Write a linear equation in point-slope form to model the situation below:

Lilit [14]

Answer:

y - 14.95 = 18.075(x-1)

Step-by-step explanation:

If an internet company charges $14.95 per month and a setup fee, then we can say

1 month = $14.95

If the total cost for 9 months is $159.55

Then we can write both cases as a coordinate (1, 14.95) and (9,159.55)

The equation of a line in point slope form is expresses as

y-y0 = m(x-x0)

Find the slope m

m = 159.55-14.95/9-1

m = 144.6/8

m = 18.075

Substitute m = 18.075 and any of the coordinate in the equation to have;

Using the coordinate (1, 14.95)

y - 14.95 = 18.075(x-1)

Hence a linear equation in point-slope form that model the situation is y - 14.95 = 18.075(x-1)

(UFRGS) Se 10x = 20y , atribuindo 0,3 para log2, então o valor de é

sveticcg [70]

Answer:

$\frac{x}{y}=1.3$

Step-by-step explanation:

Informação recuperada:

(UFRGS) Se 10x = 20y , atribuindo 0,3 para log 2 , então o valor de x/y é

1) Primeiro, passando o 10 para o 2º membro como base do logaritmo:

$10x=20y \Rightarrow x=log_{10}20y$

2) Aplicando a propriedade do produto de logaritmo:

$log(AB)= logA+logB$

$x=log_{10}20y \Rightarrow x=log(2+10)y\Rightarrow x=(0.3+1)y \Rightarrow x=1.3y$

3) Como quero o quociente divido ambos os lados por y

$\frac{x}{y}=\frac{1.3y}{y}\Rightarrow \frac{x}{y}=1.3$
