Answer:

Step-by-step explanation:

15x - 10 = 10 + 6 + 2x

15x - 10 = 16 + 2x

Bringing like terms on one side

15x - 2x = 16 + 10

13x = 26

x = 26/13

x = 2

Answer:

I think it may be D

Step-by-step explanation:

A coefficient is the number being multiplied by the variable. A variable is a letter that holds an number like w x 7=? W=6. And a constant is the number by itself. In this expression 5000 is the constant 20 is the coefficient and teh variable is w so I think it is D

Scott wants to cover his patio with concrete pavers. If the patio is shaped like a trapezoid whose bases are 11 feet and 13 feet

GenaCL600 [577]

<u><em>Answer:</em></u>

Scott will need 168 ft² of pavers to cover his patio

<u><em>Explanation:</em></u>

Scott wants to cover a trapezoid-shaped patio

<u>This means that:</u>

To get the number of square feet of pavers he'll need, we need to get the area of his patio

<u>Area of trapezium id calculated as follows:</u>

$Area = \frac{base_{1}+base_{2}}{2} * height$

<u>We are given that:</u>

base₁ = 11 ft

base₂ = 13 ft

height = 14 ft

<u>We now substitute with the givens to get the area as follows:</u>

$Area = \frac{11+13}{2} * 14 = 168ft^2$

<u>This means that:</u>

Scott will need 168 ft² of pavers to cover his patio

Hope this helps :)

Without using logarithm tables, find the value of x given that: 2log2/3 = 1/2logx - log 18 + log 16

sweet-ann [11.9K]

Answer:

$x=\frac{1}{4}$

Step-by-step explanation:

<u>Given:</u>

$2log(\frac{2}{3})=\frac{1}{2}log(x)-log(18)+log(16)$

<u>Use the Power Rule Law:</u>

$log(\frac{2}{3}^2)=log(x^{1/2})+log(16)-log(18)$

<u>Use the Quotient Rule Law:</u>

$log(\frac{4}{9})=log(\sqrt{x})+log(\frac{16}{18})$

<u>Use the Product Rule Law:</u>

$log(\frac{4}{9})=log(\frac{16\sqrt{x}}{18})$

<u>Simplify:</u>

$log(\frac{4}{9})=log(\frac{8\sqrt{x}}{9})$

$\frac{4}{9}=\frac{8\sqrt{x}}{9}$

$4=8\sqrt{x}$

$\frac{4}{8}=\sqrt{x}$

$\frac{1}{2}=\sqrt{x}$

$\frac{1}{4}=x$
