n Ms. Salmon’s 4th grade class, there are half as many boys as there are girls. There are 30 students all together. How many are boys? How many are girls? Explain how you solved the problem.
Answer:
10 boys, 20 girls
Step-by-Step Explanation:
So there are 30 students
Our first assumption is 15 boys, 15 girls. 50-50, right?
But there are half as many boys as girls.
So there's twice as many girls in the class.
Let's have B = boys and G = girls
B + 2G = All 30 Students
2G = 2/3 (20/30)
B = 1/3 (10/30)
20 + 10 = 30
10 boys, 20 girls.
Hope this helps! I suggest asking your teacher for help just to make sure you understand it.
What is the slope of the line that passed through the points (-3,-3) and (-5,-2)
Answer: -1/2
Step-by-step explanation:
Formula for finding slope: (y1 - y2) / (x1 - x2).
This is because the slope is the change of y and x values, so we shall find the difference between the y and x points.
Let x1 be -3, and y1 be -3, and the second point- let x2 be -5, and y2 as -2.
We plug them in and we get (-3 - (-2)) / (-3 - (-5)).
= -1 / 2

fill in the blank to make the two fractions equivalent. 4/5 = ?/25
Answer:
20
Step-by-step explanation:
5 times 5 is 25 so that is the bottom and 4 times 5 is 20, so it is 4/5 and 20/25.
Answer:
20
Step-by-step explanation:
First 4x5 =20 which means it's going to be 20/25 if you don't understand let me help. You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.
Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:
25
1
So now that we've converted 25 into a fraction, to work out the answer, we put the fraction 4/5 side by side with our new fraction, 25/1 so that we can multiply those two fractions.
That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look: 4 x 25
5 x 1
=
100
5
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 100 and 5 is 5.
We can now divide both the new numerator and the denominator by 5 to simplify this fraction down to its lowest terms.
100/5 = 20
5/5 = 1
When we put that together, we can see that our complete answer is:
20
1
The complete and simplified answer to the question what is 4/5 of 25 is:

En invierno, el precio de las manzanas subió repentinamente $0.75 por kilo. Sam compró 3 kilos de manzana al precio nuevo, por un total de $5.88
Answer:
X + 0.75 x 3 = 5.88
Step-by-step explanation:
Explicación paso a paso:
X = 1k de manzanas
0.75 = lo que aumenta el valor de X
3 = los 3k de manzanas que equivalen a 5.88 como resultado
esa es la ecuacion, solo queda resolverla despejando las X del kilo para descubrir cuanto cuesta un solo kilo de manzanas
The cost of the apples was $1.21 per kg before winters.
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have in winters, the price of apples suddenly rose by $0.75 per kilo. Sam bought 3 kilos of apples at the new price, for a total of $5.88.
Assume that the cost before winters be $x per kg. Then, during the winters, the cost would be $(x + 0.75) per kg.
Now -
3 kg of apple cost $5.88
1 kg of apple will cost $(5.88/3) = $1.96 per kg
So, we can write -
(x + 0.75) = 1.96
x = 1.21
Therefore, the cost of the apples was $1.21 per kg before winters.

Step-by-step explanation:
it is undefined because its a vertical line.
Answer:
slope is undefined u
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 3 ) and (x₂, y₂ ) = (1, 0 )
m = [tex]\frac{0-(-3)}{1-1}[/tex] = [tex]\frac{0+3}{0}[/tex] = [tex]\frac{3}{0}[/tex]
Since division by zero is undefined then the slope of the line is undefined
find g(4x)
g(x)=x²-4
Answer:
g(x) = x² - 4 is already in form of a variable, I.e., x
g(4x) takes another variable, I.e., 4x
Same as before, 4x takes over x:
=> g(4x) = (4x)² - 4
(ax)² = a²x², where a is some arbitrary constant. Answer:=> g(4x) = 16x² - 4
OR
=> g(4x) = 4{4x² - 1}
[tex]\large{\rm{\underline{\underline{Answer:}}}}[/tex]
Given g(x) = x² - 4 which is function of x and changes with the value of xNow we have g(4x). This means, we have to replace x by 4x and correspondence to this, the equation will change. I.e.
⇛ g(4x) = (4x)² - 4
⇛ g(4x) = 16x² - 4 / 4(4x² - 1) [answer]

C) No; 3.8 + 7.4 is greater than 11.
D) Yes; 3.8 + 7.4 is greater than 11.
Using the sum of the sides of the triangle, it is found that the correct option is:
D) Yes; 3.8 + 7.4 is greater than 11.
What is the condition of the sum of the sides of the triangle?In a triangle, the sum of the lengths of the two smaller sides has to be greater than the length of the greater side.In this problem:
The lengths of the smaller sides are 3.8 and 7.4.Of the greater side, is 11.Hence:

Capitals hockey game was 18,397. This year, the
average attendance was 18,506. By what percent did
the attendance increase from 2010 to now? Round your
answer to the nearest tenths place.
Answer:
0.5924%.
Step-by-step explanation:
The requried percentage change in attendance increase from 2010 to now is 0.608%.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
In 2010, the average attendance at a Washington capitals hockey game was 18,397.
This year, the average attendance was 18,506.
Percentage change = 18506 - 18397/18397 × 100%
= 0.608%
Thus, the requried percentage change in attendance increase from 2010 to now is 0.608%.

Subtract the linear expressions.
(−3.6x+9.4)−(1.9x+3.6)
What is the difference?
Enter your answer in the box.
Answer:
-5.5x + 5.8
Step-by-step explanation:
(-3.6x + 9.4) - (1.9x + 3.6)
(-3.6x + 9.4) - 1.9x - 3.6
-5.5x + 5.8
The required difference between linear expressions is -5.5x + 5.8.
What is the linear expression?Linear expressions are mathematical statements with a minimum of two terms containing variables or numbers.
The linear expressions are given in the question
(-3.6x + 9.4) - (1.9x + 3.6)
We have to determine the difference between linear expressions
(-3.6x + 9.4) - (1.9x + 3.6)
Distribute the negative sign in the above expression
-3.6x + 9.4 - 1.9x - 3.6
Rearrange the terms of variable x in the expression
-3.6x - 1.9x + 9.4 - 3.6
Apply the arithmetic operation in the likewise terms
-5.5x + 5.8
Therefore, the required difference between linear expressions is -5.5x + 5.8.
