Find value of x
I need it fastttttt
Answer:
x=1
Step-by-step explanation:
you have to put x on one side. send -10 to the other side. Add 10 on both sides to delete 10.
7x-10+10=3x-6+10
now it leaves you with 7x=3x+4
Now you have to send 3x to the other side because you are solving for x. subtract both sides by 3x to delete 3x on the other side.
7x-3x=3x-3x+4
how it leaves you with 4x=4
now you divide both sides by 4
4/4x=4/4
Hence, x=1
Answer:
standard form: 4x - 4 = 0
factorisation: 4(x - 1) = 0
solutions: x = 4/4 = 1
therefore, x is 1

Joe is 6 feet tall and cast a 3 foot shadow. He is standing next to a building that cast a shadow that is 20 feet long. How tall is the building.
Answer:
40 feet
Step-by-step explanation:
Answer:
40 feet tall
Step-by-step explanation:
6/2 =3
?/2 =20
*2 *2
? = 40
you do inverse operations because 6 divided by 2 is 3... the ? is the variable for how tall the building is... ? divided by 2 = 20 so you multiply 2 and 20 to get the total height

Mindy looks outside her window and sees limp tomato plants in the garden. She quickly waters the plants, and by the end of the day, the plants are upright with firm stems. How did watering the tomato plants straighten the stems?
Answer:
Do you have options.
If not I am guessing because the roots sucked the water up distributing it throughout the entire plant making it hydrated and strong to stand.

Please help asap lol ty
Answer:
x=4
y= 1/2
Step-by-step explanation:
The easiest way to solve this is to subtract the two equation from each other
wee have
4x+2y=17
- 3x+2y=13
___________
x=4
Now that we know what x is we can solve for y
4(4)+2y=17
16+2y=17
2y=1
y= .5
c = the number of Nora's coworkers who attend the picnic v = the number of veggie burgers Nora prepares Which of the variables is independent and which is dependent?
Answer: Independent variable = c
Dependent variable = v
Step-by-step explanation:
The independent variable does not depend on any other variable.Dependent variable dependent on another variable.Given variables:
c = the number of Nora's coworkers who attend the picnic
v = the number of veggie burgers
Here the number of burgers required is dependent on the number of Nora's coworkers who attend the picnic.
Therfeore, Independent variable = c
Dependent variable = v

Find the value of x please and thank you
Given:
In triangle DEF, HG is parallel to DF.
To find:
The value of x.
Solution:
In triangles DEF and GEH,
[tex]\angle DE F\cong \angle GEH[/tex] (Common angle)
[tex]\angle EDF\cong \angle EGH[/tex] (Corresponding angle)
[tex]\Delta DE F\sim \Delta GEH[/tex] (By AA property of similarity)
We know that corresponding sides of similar triangle are proportional.
[tex]\dfrac{DE}{GE}=\dfrac{DF}{GH}[/tex]
[tex]\dfrac{9+(x+5)}{x+5}=\dfrac{12}{6}[/tex]
[tex]\dfrac{x+14}{x+5}=2[/tex]
[tex]x+14=2(x+5)[/tex]
[tex]x+14=2x+10[/tex]
Isolating variable terms, we get
[tex]x-2x=-14+10[/tex]
[tex]-x=-4[/tex]
[tex]x=4[/tex]
Therefore, the value of x is equal to 4.
Did you sleep with a comfort object as a child? Do you still? No
need to stuff that teddy bear from your infant years in your closet the
next time you have a guest over—the odds are good that he or she has
a comfort object, too. A study conducted by Sleepopolis and
OnePoll reported that 34% of adults still sleep with a stuffed animal,
blanket, or other sentimental object, according to a survey of a random
sample of 100 adults. A similar study, based on a random sample of 80
children reports that 75% of children sleep with a comfort object.
Do these data provide convincing evidence that the proportion of adults
who sleep with a comfort object is less than the proportion of children
who sleep with a comfort object? Justify your answe
Answer:
depends how random it was, it could vary between countries and stuff. but lets say its random between ethnicities. I think it doesn't really have enough people to be sure, I would say a thousand and not 100, but that's just me.

0. Multi-Step Nathanial has a dog walking
business. He charges $3 for every 15 minutes
of walking. How much will Nathanial charge to
walk a dog for one hour?
Answer:
Nathanial will charge $12
Step-by-step explanation:
If he charges $3 per 15 minutes, one hour is 60 minutes. And 60 divided by 15 is 4 so you do 3x4 because he charges $3 per 15 minutes.

how many solutions does 2x+6=7x5 have
Answer:
14.5
Step-by-step explanation:
2x=7*5-6 will be 14.5
Answer:
One solution.
Step-by-step explanation:
Since the right side of the equation is a constant, there can only be one solution:
[tex]2x+6=7*5[/tex]
[tex]2x+6=35[/tex]
[tex]2x=35-6[/tex]
[tex]2x=29[/tex]
[tex]x=14.5[/tex]
14.5 is the only answer.

can someone please help me with this question
Answer:7 weeks
Step-by-step explanation:
Multiply each equation by a constant that would help to eliminate the y terms.
2x-5y = -21
3x-3y = -18
What are the resulting equations?
6x-15y = -63
- 15x+15y = 90
6x-15y = 63
-15x+15y = 90
6x-15y=-63
- 15x+ 15y = -90

Answer: 6:5 ; 18:15 ; 36:30
Step-by-step explanation:
6/5 = x/15
5x = 6(15) use cross multiply
5x = 90
x = 18
6/5 = 36/x
6x = 5(36) use cross multiply
6x = 180
x = 30
Answer:
Answer below
Step-by-step explanation:
For every 6 taxis, there are 5 busses
if there are 15 busses, thats 3 sets of 5
6x3 is 18. so for every 15 busses, there are 18 taxis
If there are 36 taxis, thats 6 sets of 6
since there are 5 busses for every 5 taxis
5x6 is 40
for every 30 busses, there are 36 taxis
Identify the best measure of Sin C
Answer:
[tex]\sin C=\frac{28}{35}[/tex]
Step-by-step explanation:
In a right triangle, [tex]\sin\theta =\frac{\text{opp}}{\text{hyp}}[/tex]. In this case, the side opposite to angle [tex]C[/tex] is 28 and the hypotenuse is 35. Therefore, the exact value of [tex]\sin C[/tex] is [tex]\boxed{\frac{28}{35}}[/tex].

The total bill for a group of friends having dinner was $130. They paid the entire bill using only $5 and $ 10$ bills. In total, there were 16 bills used. How many of each type of bill were used to pay the bill?
Answer:
6 five dollar bills and 10 ten dollar bills
Step-by-step explanation:
130 = 5x + 10y
x + y = 16
A boat travels 10 miles per hour upstream and 16 miles per hour downstream. How fast is the current?
Answer: The speed of the current is 3 miles per hour.
Step-by-step explanation:
Let x = speed of boat , y= speed of current.
Given:
x-y=10 (Upstream) ...(i)
x+y= 16 (Downstream) ...(ii)
Adding (i) and (ii), we get
2x=26
⇒ x= 13
Put x=13 in (i), we get
13-y=10
⇒ y=13-10
⇒ y=3
Hence, the speed of the current is 3 miles per hour.
