Step-by-step explanation:
9+9y=18y
9y-9= y
9(y-1)=9y−9 simplifed
9(y+1)=9*1y
9y+1=10y
1+9y=10y

There are 26 boys and 28 girls from Stella’s class riding on the bus. Some students from a different class join them, so 2 additional boys and 2 additional girls board the bus.
Does the ratio of boys to girls remain the same? Explain your answer. As part of your explanation, give both the old and the new ratios, in lowest terms, of boys to girls on the bus.
Answer:
Yes
Step-by-step explanation:
) Which ratios have a unit rate greater than 1? Choose ALL that apply. 9 5 miles : 6 hour 3 (7) 7 miles : hour 4 1 2 miles: 3 hours 8 2 NI 9 1 3) 4 miles : 3- hours 3 1 3 mile : 2- hours 3 8 } mile : 2 miles : 3 hours 5
I got this right, look....
Evidence:
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The ratios that have a unit rate greater than 1 are:
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
The unit rate of each given ratio.
9/8 miles = 5/6 hours
Multiply 6/5 on both sides.
6/5 x 9/8 miles = 1 hour
54/40 miles = 1 hour
27/20 miles = 1 hour
1.35 miles = 1 hour
4 miles = 3(1/3) hours
4 miles = 10/3 hours
Multiply 3/10 on both sides.
3/10 x 4 miles = 1 hour
6/5 miles = 1 hour
1.2 miles - 1 hour
7 miles = 3/4 hours
Multiply 4/3 on both sides.
4/3 x 7 miles = 1 hour
28/3 miles = 1 hour
9.33 miles = 1 hour
We see that,
All of them have unit rates greater than 1.
Thus,
The ratios that have a unit rate greater than 1 are:
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours

Answer:
x°=48°
Step-by-step explanation:
angle Y=x°
angle Z= angle y, because equal side of the angles are equal.
so, angle X +angleY+ angle Z=180° ( angle sum property of triangles)
therefore 84°+x°+x°=180°
2x°=180° -84°
2x°=96°
x°=48°
A line passes through the origin and has a slope of 2/3
Answer:
y=2/3x
Step-by-step explanation:
the origin is the point (0,0) and the given slope is 2/3
the equation for slope-intercept form is y=mx+b, where m is the slope and b is the y intercept
the slope is given, meanwhile, the y intercept is the point where the line passes through the y axis, and the x value is 0.
In this question, we actually have the y intercept given, which is (0,0)
we can put it all together then:
y=2/3x+0
or
y=2/3x
Hope this helps :)
Which equation best represents the relationship
between x and y in the graph?
A. y = x + 2
C. y = 2x + 2
B. y = 2x - 2
D. y = Vzx - 2
Answer:
C y= 2x +2
Step-by-step explanation:
Look at the graph and look at the dots. For example if you look at negative 1 on the x-axis there is a dot there. so it now you count up to where you see the next dot on the y-axis. Which it goes up 2, then count to the right towards the Y-Axis which is one. now you left with 2/1. since it is going up 2 it will be positive and 2 over 1 is simplified so you are left with 2x and the B will be 2 because the line goes through 2 on the y-axis. This equation should help you y=mx+b m is the slope and B is the y axis
Simplify
1/2 + (3/8 - 1/8)^2
point q is located at (18, 5). The x-coordinate of point r id half as much as the x-coordinate of point Q The y-coordinate of point r is 3 more than the y-coordinate of point q
Answer:
R (27, 8)
Step-by-step explanation:
The coordinate plane is a two-dimensional plane consisting of the y axis (vertical line) and x-axis (horizontal line). The origin is known as the zero point (reference point) is the intersection of the x axis and y axis.
A point on the coordinate plane is represented by (x, y) where x is the x coordinate and y the y coordinate.
Given point Q = (18, 5), the x coordinate is 18 and the y coordinate is 5.
Let the location of point R = (a, b)
a = x-coordinate of point Q + 1/2 of x-coordinate of point Q = 18 + (1/2)*18 = 27
b = y-coordinate of point Q + 3 = 5 + 3 = 8
Therefore R = (27, 8)

Help
Answer:
steps below
Step-by-step explanation:
Are you going to solve the value of A or just a proof the equation
cos 2A = cos² A - sin² A
2cos²A-cos2A-1 = 2cos²A - (cos² A - sin² A) - 1 = cos² A + sin² A - 1
2cos²A-cos2A-1 = 1 - 1 = 0

A sector of a circle has an area of 16.75 square inches. The central angle is 120 degrees. Calculate the length of the radius.
please help :)
Answer:
17.14
Step-by-step explanation:
Area of sector= 120/360(πr^2)
16.75^2 = 120π/360 (r^2)
(π/3)16.75^2 = π/3 r^2(π/3)
293.8 = r^2
r= √293.8
r= 17.14

Angle ABC is right-angled at C. If AC = 5cm and BC = 12cm find the length of AB
BC= 12cm
AC = 5cm
According to Pythagoras theorem ,
12^2 + 5^2 = AB^2
144+25 =169 ..
so AB^2 = 169
AB=√169 ..
Therefore, AB= 13cm ..

The ratio of adults to kids in a school is 3 : 7. If there is a total of 200 people, how many of them are students? *
Answer:
60 students 140 adults
Step-by-step explanation:
so 200 into 3 : 7
first we just do this: 200 ÷ (3+7) = 200 ÷ 10 = 20
so a 1 in the ratio is 20 people
and theres 3 : 7
so 3 * 20 = 60
7 * 20 = 140
60 kids to 140 adults
Answer:
140 are students
Step-by-step explanation:
let k = number of kids
set up proportion based on 7 out of 10 are kids
7/10 = k/200
cross-multiply: 10K = 1400
Solve the following for the variable x.
3x - 16 = 38
Answer: x= 18
Step-by-step explanation:
3x - 16 = 38
38 + 16 = 54
3x/3 = 54/3
X= 18
Step-by-step explanation:
[tex] \tt{3x - 16 = 38}[/tex]
We want to remove the 16 first. So , Since the original equation is - 16 , we are going to use the oppsite operation and add 16 to both sides.
⟶ [tex] \tt{3x - 16 + 16 = 38 + 16}[/tex]
Simplify ! - 16 + 16 = 0 on the left. 38 + 16 = 54 on the right.
⟶ [tex] \tt{3x = 54}[/tex]
Now , we need to think how to remove the coefficient 3. Since the opposite of multiplication is division , we are going to divide both sides by 3.
⟶ [tex] \tt{ \frac{3x}{3} = \frac{54}{3}} [/tex]
Simplify ! 3 / 3 = 1 on the left and 54/3 = 18 on the right . So, our answer is 18.
[tex] \pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = 18}}}}}}}[/tex]
Hope I helped ! ♡

A farmer wants to make a fenced square pen. He has a total of 100 meters of fencing. He wants to determine the possibilities for the area of the pen. Let A represent the area of the pen, in square meters.
Answer:
I put B and A= 25
I got it on another website but I'm not entirely sure.
The square is asymmetrical quadrilateral, which implies it has 4 equal sides and angles. This can also be described as a rectangle having two neighboring sides that are both the same length.
It ensures that the elements are perpendicular, either at right angles to one another.
The length of the square pen is [tex]\sqrt{A}[/tex], and the perimeter should be no more than 100 then the perimeter of a square is 4a the over is [tex]a^2[/tex] So, the equation :
[tex]\to 4\sqrt{A}=100\\\\ \to \sqrt{A}=\frac{100}{4}\\\\\to \sqrt{A}=25[/tex]
Therefore, the final answer is "25".

315
8
-0.25
✓7
17
36
Answer:
6.7234724... ; ✓7
Step-by-step explanation:
In the most simplest of terms, we can explain irrational numbers as numbers which cannot be expressed as a ratio of two integers usually because they cannot give an exact value when evaluated.
Using the values given :
6.7234724... - - >This is an irrational number because the '...' depicts that the values are unending and as such an exact expression in the form of a ratio (p/q) cannot be determined.
315, 26, 17, 8 - - - > Is a rational number, it could be express in ratio form as : 315/1. 315 is an integer and all integers are rational.
-0.25 - - > it could be expressed as - 1 /4. Hence it is a rational number.
✓7 - irrational as the simplification gives : 2.6457513...
