Answer:

15x + 15

Step-by-step explanation:

Combine like terms. Like terms are terms with the same amount of variables. Set the equation so that the terms are grouped:

6x + 9x + 6 + 9

Combine like terms:

(6x + 9x) = 15x

(6 + 9) = 15

15x + 15 is your answer.

Given that rectangle MNOP ~ rectangle STUV, what is the length of ¯¯¯¯¯¯ T U ?Rectangle M N O P is shown with segment N O labele

Sergeu [11.5K]

Answer:

$TU = 15$

Step-by-step explanation:

Given

$\square MNOP \simeq\ \square STUV$

$NO = 10$

$OP = 4$

$TU = x$

$UV = 6$

Required

Determine the length of TU (i.e. x)

Because both shapes are similar, then the following equivalent ratios exist:

$NO : OP = TU : UV$

Substitute values for NO, OP, TU and UV

$10 : 4 = x : 6$

Represent as fraction

$\frac{10 }{ 4 } = \frac{x }{ 6}$

Multiply both sides by 6

$6 * \frac{10 }{ 4 } = \frac{x }{ 6} * 6$

$6 * \frac{10 }{ 4 } = x$

$x = 6 * \frac{10 }{ 4 }$

$x = \frac{60 }{ 4 }$

$x = 15$

Hence:

$TU = 15$

Alex777 [14]

As shown in the question, the translation changes the points as follows:

$(x,y)\rightarrow(x+2,y-2)$

Therefore:

$\begin{gathered} C(-5,-1)\rightarrow C^{\prime}(-3,-3) \\ D(-4,3)\rightarrow D^{\prime}(-2,1) \\ E(-3,2)\rightarrow E^{\prime}(-1,0) \\ F(-2,0)\rightarrow F^{\prime}(0,-2) \end{gathered}$

At a picnic there were 3 times as many adults as children and twice as many women as men. If there was a total of x men, women,

Dennis_Churaev [7]

Answer:

$\dfrac{x}{4}$

C is correct.

Step-by-step explanation:

At a picnic,

Number of adults is 3 times as number of children.

Number of women is twice as number of men.

Total number of men, women and children at the picnic be x

Let number of children be c

Let number of men be m

Let number of women be w

# Number of women is twice as number of men, w = 2m

# Number of adults is 3 times as number of children, w + m = 3c

2m + m = 3c (∴ w=2m )

c = m

Total number of men, women and children at the picnic be x

∵ c + m + w = x

m + m + 2m = x

4m = x

Number of men, $m=\dfrac{x}{4}$

Hence, The total number of men will be $\dfrac{x}{4}$
