Answer:
x = -1
Step-by-step explanation:
First you multiply by crossover and you get 3(5-x)=18
Then divide the two wings and you'll get 5-x=6
Then you need to separate the x from the numbers
so you move 5 to the right side and you get -x=6-5
Then you calculate it and you get -x=1
and x= -1
hope it helped <3
Answer:
[tex]x=-1[/tex]
Step-by-step explanation:
Given the equation
[tex]\frac{5-x}{9}=\frac{2}{3}[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}9[/tex]
[tex]\frac{9\left(5-x\right)}{9}=\frac{2\cdot \:9}{3}[/tex]
[tex]5-x=6[/tex]
[tex]\mathrm{Subtract\:}5\mathrm{\:from\:both\:sides}[/tex]
[tex]5-x-5=6-5[/tex]
[tex]-x=1[/tex]
[tex]x=-1[/tex]

Answer:
the first picture A.
Step-by-step explanation:
Vertical angles are just two angles that lie across from each other. The other 3 pictures are referring to adjacent angles which are two angles that lie directly next to each other.

A Toyota Prius can drive 70 miles on two gallons of gas. At this rate, how far can the Prius travel on 13 gallons of gas? Include your units.
Answer:
460 miles
Step-by-step explanation:
Since it is a ratio problem, you see that the prius drives 70 miles on 2 gallons of gas which gives you 70:2 or 70/2.
You also set up the other ratio as a fraction with the unknown value as x --> x/13.
now, you cross multiply
70/2=x/13
70*13=910
910/2=460
460 miles
Answer:
455 miles
Step-by-step explanation:
Distance Prius can travel with one gallon of gas:
70/2
= 35 miles
Distance Prius can travel with 13 gallons of gas:
35*13
= 455 miles

what is the graph of 4x + 8y = 16?
Answer:
See attachment for what the graph looks like.
Step-by-step explanation:
When you graph these equations, convert 4x+8y=16 into slope-intercept form, which should be y= -1/2x+2.
In this case, 2 is the y-intercept, the part of the line that intercepts with the y-axis, with a negative (goes downward) slope of 1/2.
The line should intersect at (0,2) and have a slope of -1/2.
The x-intercept of the line is at 4 and the y-intercept of the line is at 2. Then the graph is sketched below.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
x/a + y/b = 1
Where 'a' is the x-intercept of the line and 'b' is the y-intercept of the line.
The equation of the line is given below.
4x + 8y = 16
Convert the general form of the line into an intercept form. Then we have
4x + 8y = 16
x/4 + y/2 = 1
The x-intercept of the line is at 4 and the y-intercept of the line is at 2. Then the graph is sketched below.

Step-by-step explanation:
Answer:
$36.
Step-by-step explanation:
(Hot dog) 2 for 5: Unit price is 5/2 = 2.5
(Soda) 3 for 3 so unit price is 1 for 1.
6 sodas = 6 dollars
12 Hot dogs = 12. x 2.5 = 30 dollars.
Price for both = 30 + 6 = 36.

Which cannot be the angle measurements of triangle ABC? OmZA = 55°, mZB = 65°, mZC = 60°
OmZA = 60°, mZB = 60°, mC = 60°
MZA= 57°, MZB = 58°, mZC = 65°
MZA = 61°, mZB = 57°, mZC = 61°
Answer:
D. m<A = 61°, m<B = 57°, m<C = 61°
Step-by-step explanation:
The sum of all interior angles of a triangle is always equal to 180°.
Therefore, any set of given angle measurement of a triangle should sum up to 180°.
From the options given, the following angle measurements given in option D,
,m<A = 61°, m<B = 57°, m<C = 61° cannot be angle measurements of ∆ABC. This is because they sum up to give 179° instead of 180°.

A small deck of 5 cards consists of 3 red Jards and 2 green cards.
Draw 7 times with replacement.
Find the probability that a red card is drawn exactly 3 times.
Answer:
Approximately [tex]0.19[/tex].
Step-by-step explanation:
The cards were drawn with replacement. Therefore, the probability of drawing a red card will be [tex](3 / 5)[/tex] at every one of the seven draws. The probability of not drawing a red card would be [tex](1 - (3/5)) = (2/5)[/tex].
One way to get three red cards out of the seven draws would be [tex]\verb!red!\; \verb!red!\; \verb!red!\; \verb!green!\; \verb!green!\; \verb!green!\; \verb!green![/tex]. That corresponds to a probability of [tex](3/5)^3\, (2/5)^{7-3}[/tex].
However, there are many other ways to get three red cards during the seven draws. For example:
[tex]\verb!red!\; \verb!red!\; \verb!green!\; \verb!red!\; \verb!green!\; \verb!green!\; \verb!green![/tex], [tex]\verb!red!\; \verb!red!\; \verb!green!\; \verb!green!\; \verb!red!\; \verb!green!\; \verb!green![/tex].[tex]\cdots[/tex].[tex]\verb!green!\; \verb!green!\; \verb!green!\; \verb!green!\; \verb!red!\; \verb!red!\; \verb!red![/tex].There are [tex]\displaystyle {\genfrac{(}{)}{0}{0}{7}{3}} = 35[/tex] such ways in total to choose three draws out of seven draws.
These ways are mutually-exclusive. Each of these ways has a probability of [tex](3/5)^3\, (2/5)^{7-3}[/tex]. The probability for getting a red card on exactly three out of the seven draws would be:
[tex]\displaystyle {\genfrac{(}{)}{0}{0}{7}{3}} \, (3/5)^3\, (1 - (3/5))^{7-3} \approx 0.19[/tex].

A cat walks 3 meters toward a laser, then jumps 5 meters due south of the laser when it
sees a thing. What is the displacement of the cat (to the nearest tenth)?
Answer:
Displacement is 5.8 meters
Step-by-step explanation:
Here, we want to calculate the displacement of the cat
When we talk of displacement, we mean distance traveled in a specified direction
To find the displacement of the cat, we calculate the distance between where the cat is now from where it started off
So to calculate this, we shall have a right angled triangle where the displacement we want to calculate will be the hypotenuse
We proceed to use Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides
Mathematically, we have ;
D^2 = 3^2 + 5^2
D^2 = 9 + 25
D^2 = 34
D = √34
D = 5.8309
To the nearest tenth, the displacement is 5.8 meters
