What is the value of x?

Mathematics
1 answer:
Anit [1.1K]2 years ago
7 0

Answer:

Step-by-step explanation:

Set this up according to the Triangle Proportionality Theorem:

\frac{3x}{4x}=\frac{3x+7}{5x-8}

Cross multiply to get

3x(5x-8)=4x(3x+7)

and simplify to get

15x^2-24x=12x^2+28x

Get everything on one side of the equals sign and solve for x:

3x^2-52x=0 and

x(3x-52)=0

By the Zero Product Property,

x = 0 or 3x - 52 = 0 so x = 17 1/3

help me its easy Triangle DOG is an isosceles triangle with DO = OG, and mD = 18. What is mO? A. 18 B. 36 C. 144 D. 162
S_A_V [24]
Angle D and angle G are the base angles, which means they are equal. If D = 18, then G = 18. Since the sum of the angles of a triangle equals 180 degrees, subtract 18 + 18 from 180 to get angle O.
180 - 36 = 144
Angle O = 144

Hope this helps =)

you should spend one week worth of pay on rent. she makes 32,000 a year. what is max she should spend
deff fn [24]

Hi!


We know she makes $32,000 a year, but we need to know how much she makes in a week. Which leads us to the question,"How many weeks are in a year?".


There are about 52 weeks in a year.


To found out how much money she makes per week, divide.


money per week

32000/52 = 615.384615


I'm not sure if they want you to round up, or round down, or what, but the exact answer is 615.384615.


Hope this helps! :) -Peredhel

7<br> Slope<br> 6'<br> y-intercept (0, – 6)<br> What is the equation
Hitman42 [59]

Answer:

y = 7x -  6

Step-by-step explanation:

We are given the slope of 7 and the y-intercept of (0, -6).

We can easily write this in slope-intercept form.

y=mx+b

m - slope

b - y-intercept

Replace 'm' with '7' and 'b' with '-6'.

y=mx+b\rightarrow \boxed {y=7x-6}

Hope this helps.
