Which expression is equivalent to (7x – 5) – (3x - 2)

Nastasia [14]

Answer:

D

Step-by-step explanation:

We have the expression

$(7x-5)-(3x-2)$

First we need to distribute the negative throughout the parenthesis. Then we can combine like terms in order to simplify this expression

$(7x-5)-(3x-2)\\\\7x-5-3x+2\\\\4x-3$

This answer matches D.

Find x and y, given that line WS and line VT are parallel. Show all work!

bulgar [2K]

In the given diagram, the traingles USW and UTV are similar triangles and thus the following ratio equality applies to them.

$\frac{VT}{WS} =\frac{VU}{WU}=\frac{TU}{SU}$ ..........(Equation 1)

Checking the diagram given, we see that:

VT=y, WS=22, VU=8, ST=x-2

WU=WV+VU=12+8=20

TU=5

SU=ST+TU=(x-2)+5=x+3

Thus, substituting the required values in (Equation 1) we get:

$\frac{y}{22}=\frac{8}{20}=\frac{5}{x+3}$

Now, as can be clearly seen, to find y we will use the first two ratios as:

$\frac{y}{22}=\frac{8}{20}$

$y=\frac{8\times 22}{20}=8.8$

In a similar manner, to find the value of x we can use the last two ratios:

$\frac{8}{20}=\frac{5}{x+3}$

After cross multiplication we get:

$5\times 20=8(x+3)$

Which can be simplified as:

$x+3=\frac{100}{8} =12.5$

Thus, $x=12.5-3=9.5$

Therefore, the required answer is:

x=9.5 and y=8.8

4/5(x+5/6)-2/3(x-1/4)=7/6

solniwko [45]

Answer and Step-by-step explanation:

$Hello~let's~solve~your~equation:$

<u>Step 1: Simplify both sides of the equation:</u>

$(\frac{4}{5}) (x)+(\frac{4}{5})(\frac{5}{6})+\frac{-2}{3}x+\frac{1}{6} =\frac{7}{6}$ $(Distribute)$

$\frac{4}{5}x+\frac{2}{3}+\frac{-2}{3}x+\frac{1}{y\6}=\frac{7}{6}$

$(\frac{5}{5}x+ \frac{-2}{3}x )+(\frac{2}{3}+ \frac{1}{6})=\frac{7}{6}$ $(Combine~like~terms)$

$\frac{2}{15}x+\frac{5}{6}=\frac{7}{6}$

<u>Step 2: Subtract 5/6 from both sides:</u>

$\frac{2}{15}x+\frac{5}{6}- \frac{5}{6} =\frac{7}{6} -\frac{5}{6}$

$\frac{2}{15}x=\frac{1}{3}$

<u>Step 3: Multiply both sides by 15/2:</u>

$(\frac{15}{2}) *(\frac{2}{15}x)=(\frac{15}{2})*(\frac{1}{3})$

$x=$ $\frac{5}{2}$

Use the Law of Sines to solve the triangle. Round your answers to two decimal places.

mario62 [17]

Answer:

Step-by-step explanation:

The Law of Sines is

$\frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c}$

Filling in what we are given:

$\frac{sin(110.8)}{25.3}=\frac{sin(18.2)}{c}$

Cross multiply to get

$csin(110.8)=25.3sin(18.2)$ and divide to solve for side c:

$c=\frac{25.3sin(18.2)}{sin(110.8)}$ which gives you that

c = 8.45

We know that angle B has to be the difference between 180 and angle A and angle C, so

angle B = 51

Now we can solve for side b:

$\frac{sin(110.8)}{25.3}=\frac{sin(51)}{b}$ and

$b=\frac{25.3sin(51)}{sin(110.8)}$ and

b = 21.03
