In Ellens Math class, there are 2 boys for every 3 girls. if there are 21 girls in the class, how many boys are in the classroom.
Answer:
14 boysStep-by-step explanation:
Given,
There are 3 girls for every 2 boys
So,
For every 1 girl
[tex] = \frac{2}{3} \: boys [/tex]
Therefore,
For every 21 girls,
[tex] = \frac{2}{3} \times 21 \: boys[/tex]

solve the following equations 6÷x=18
[tex]\boxed{\underline{\bf \: ANS WER}}[/tex]
[tex] \sf \frac{6}{x} = 18 \\ [/tex]
Variable x cannot be equal to 0 as division by zero is not defined. Multiply both sides of the equation by x.
[tex] \sf \: 6=18x [/tex]
Swap sides so that all variable terms are on the left-hand side.
[tex] \sf \: 18x=6 [/tex]
Divide both sides by 18.
[tex] \sf \: x=\frac{6}{18} \\ [/tex]
Reduce the fraction [tex] \sf\frac{6}{18}[/tex] to its lowest terms by extracting and cancelling out 6.
[tex] \sf \: x=\frac{1}{3} \\ [/tex]
[tex] \sf \: x=\frac{1}{3}\approx \boxed{\underline{0.33... }}\\ [/tex]

put in order , smallest to largest 0.13 ,0.7 , 0.6
Answer:
0.13, 0.6, 0.7
Step-by-step explanation:
Basically when comparing a decimal from least to greatest look at the tenths place. Whoever's is the smallest, is the smallest decimal. Then you look at the second smallest etc. If two tenths are the same then you would compare the hundredths place so on.

You have one box that is 1 4/11
feet tall and a second box that is 1.36 feet tall. Write the decimal expansion for
. If you stack the boxes, about how tall will the stack be?
The stacked boxes would be 2.72 feet tall
The height of the stacked box is the sum of the lengths of the two boxes
1 4/11 is a mixed number and it has to be converted to a decimal
A mixed number is a number that has a whole number and a proper fraction.
A proper fraction is a fraction is which the numerator is less than the denominator.
The whole number is 1 and the proper fraction is 4/11
To convert to a decimal, divide the numerator by the denominator. Add this number to the whole number
4/11 = 0.36
1 + 0.36 = 1.36 feet
Height of the stacked boxes = 1.36 + 1.36 = 2.72 feet

|2x+9|>10=5 Please help ASAP
Simplifying
2x + 9 + -10 = -5
Reorder the terms:
9 + -10 + 2x = -5
Combine like terms: 9 + -10 = -1
-1 + 2x = -5
Solving
-1 + 2x = -5
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '1' to each side of the equation.
-1 + 1 + 2x = -5 + 1
Combine like terms: -1 + 1 = 0
0 + 2x = -5 + 1
2x = -5 + 1
Combine like terms: -5 + 1 = -4
2x = -4
Divide each side by '2'.
x = -2
Simplifying
x = -2

Solve for x: 4x + 1/2 (2x + 4) > 12
( 9th grade Algebra 1)
Answer:
x > 2
Step-by-step explanation:
Distribute and cross-simplify 1/2 with parenthesis
4x + x + 2 > 12
Solve left side
5x + 2 > 12
Subtract 2 from both sides
5x > 10
Divide both sides by 5
x > 2

A solution to a system of equations are where the two lines cross over each other.
System A the graph shows one line which means the two lines are on top of each other. This means any point on the lines are a solution so there are infinite number of solutions.
System B, the lines cross at one point is there is only one solution which is at (-3,2)
System C the two lines are parallel to each other and never cross so there are no solutions.
Step-by-step explanation:
(i) Infinite solution
If there is only one line then it is a infinite solution.
(ii) One solution
Both are intersecting each other.
Solving
-x - 1 = x + 5
-x - x = 5 + 1
-2x = 6
x = 6/-2
x = -3
y = -x + 5
y = -3 + 5
y = 2
(iii) No solution
Because they are parallel to each other
if x=1+3i ,y=x-i find the value of x^2-y^2
Answer:
Step-by-step explanation:
x = 1 + 3i
x^2 = (1 + 3i)(1 + 3i)
f: 1 * 1 = 1o: 1 * 3i = 3ii: 3i * 1 = 31L: = 3i * 3i = 9i^2 = - 9x^2 = 1 + 6i - 9 = -8 + 6i
By a similar method
y = (x - i)
y^2 = x^2 - 2i*x + i^2
y^2 = x^2 - 2ix - 1
y^2 = -8+6i - 2i(1 + 3i) -1
y^2 = -8+6i -2i - 6i - 1
y^2 = -8 - 2i - 1
y^2 = - 9 - 2i
x^2 - y^2 = -8 + 6i - (9 - 2i)
x^2 - y^2 = -8 + 6i - 9 + 2i
x^2 - y^2 = -17 + 8i

For which discriminant is the graph possible?
A. b2 – 4ac = 0
B. b2 – 4ac = 6
C. b2 – 4ac = –2
Answer:
A. b2 – 4ac = 0
Step-by-step explanation:
Hey user☺☺
Option a is correct
Because the graph has only one solution.
As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.
Hope this will help☺☺
