find the value of x that makes def ~ xyz
x=
Answer:
x = 3.5
Step-by-step explanation:
[tex] \triangle DEF \sim \triangle XYZ\\\\
\therefore \frac{DE}{XY} =\frac{DF}{XZ} \\\\
\therefore \frac{5}{7.5} =\frac{7}{3x} \\\\
\therefore 3x = \frac{7.5\times 7}{5} \\\\
\therefore x = \frac{7.5\times 7}{3\times 5} \\\\
\therefore x = \frac{52.5\times 7}{15} \\\\
\therefore x = 3.5[/tex]
Step-by-step explanation:
If [tex]\triangle[/tex]DEF~[tex]\triangle[/tex]XYZ
[tex]\tt{\dfrac{DE}{XY}=\dfrac{EF}{ZY}=\dfrac{DF}{XZ} }[/tex]
According to the question
[tex]\tt{\dfrac{5}{7.5}=\dfrac{3}{4.5}=\dfrac{7}{3x} }[/tex]
[tex]\tt{\dfrac{3}{4.5}=\dfrac{7}{3x} }[/tex]
[tex]\tt{ 9x=4.5×7}[/tex]
[tex]\tt{ 9x=31.5 }[/tex]
[tex]\tt{ x=\dfrac{22.5}{9} }[/tex]
[tex]\tt{x=3.5 }[/tex]

Carlos wants to rent a car for the particular car you on gentle rental charges 185 per week plus $0.25 per mile driven rental charges a flat fee of 275 per week what is the number of miles driven so that rented from dental rental cause carlos less than renting from rental giant
Answer:
The indifference point is 360 miles.
Step-by-step explanation:
Giving the following information:
Rental 1:
Total cost= 185 + 0.25*x
x= miles driven
Rental 2:
Total cost= $275
Now, we need to equal both formulas and isolate x:
185 + 0.25x = 275
0.25x = 90
x= 90/0.25
x= 360
The indifference point is 360 miles.

Hi , I have geometric question
What is x angel ?
36 ft
27 ft
What is the length of the hypotenuse?
C
feet
is this right? Whats the answer to C?
Answer:
a. Multiplication property of equality
b. Distributive property
c. addition property of equality
Step-by-step explanation:
The first one is wrong because you are multiplying the 2 on both sides to make it equal. There was nothing that they substituted for.
The second one will be the distributive property not the subtraction property of equality. They distributed the 2 into the [tex]\frac{1}{2}x[/tex] and the [tex]-5[/tex]. So that clears up that this step was the distributive property.
This one will be the addition property of equality because when you have a negative number you do the inverse so they added the 10 on both sides. Therefore it's the addition property of equality.

Will give brainliest.
Answer:
slope=1/2
the given point=(0, 13/2)
Step-by-step explanation:
change the equation to the y=mx+b format
y-8=1/2(x-3)
y=1/2x-3/2+8
y=1/2x+13/2
m=slope
1/2=slope
given point(y-intercept)= the constant
given point=13/2

Jenny planned to solve 2/3 of homework
On Saturday she solved 28 problems, which is 7/8 of the planned number
Planned number is:
28 : 7/8 = 28 * 8/7 = 32 problems
Jenny's homework was:
32 : 2/3 = 32 * 3/2 = 48 problems

Deborah bought a computer for 25% off the list price. If the list price is $2,428, how much did Deborah spend? A. $607 B. $1,821 C. $2,115 D. $2,403
Answer:
Option A, [tex]\$607[/tex]
Step-by-step explanation:
Given: Deborah bought a computer for [tex]25\%[/tex] off the list price.
The list price is [tex]\$2,428[/tex].
To find: The amount Deborah spent on the computer.
Solution: We have,
List price of the computer [tex]=\$2,428[/tex].
Deborah bought the computer for [tex]25\%[/tex] off the list price.
The amount Deborah spent on the computer [tex]=25\% \times 2,428[/tex]
[tex]=\frac{25}{100}\times2428=\frac{2428}{4} =\$ 607[/tex].
So, Deborah spent [tex]\$607[/tex] on the computer.
Hence, option A is correct.

Back in ye olden days, cell phone companies charged for texting. A cell phone company charges 10 cents per text message if a customer sends up to 100 messages per month, 8 cents for 101-200 messages, and 6 cents for 201-300 messages. If today is the last day of the month, and you've sent 200 texts, is it worth it to send 1 more text message?
Answer: It is worth it.
Step-by-step explanation:
If a customer sends 101 - 200 texts in a month, they get charged 8 cents per text.
If they send 201 - 300, they get charged 6 cents per month.
If you have sent 200 texts, your charge for the month will therefore be:
= 200 * 8
= $16.00
If you send the 201th text, you will be charged 6 cents per text. Total charge would be:
= 201 * 6
= $12.06
If you send 1 more text, it will be worth it because you will save:
= 16 - 12.06
= $3.94
