Answer:
3/5 * 4/7 = 12/35
you can find the answer by multiplying the numerator by the other numerator and the denominator by the other denominator
[tex]\frac{3}{5} \times \frac{4}{7}[/tex] in its simplest form is [tex]\frac{12}{35}[/tex]
To evaluate the given multiplication in its simplest form, we will find the product of the given two fractions.
First, let us write the given fractions properly
That is,
[tex]\frac{3}{5} \times \frac{4}{7}[/tex]
Now, we will carry out the multiplication operation
[tex]\frac{3}{5} \times \frac{4}{7} = \frac{3 \times 4}{5 \times 7}[/tex]
Then, we get
[tex]\frac{3}{5} \times \frac{4}{7} = \frac{12}{35}[/tex]
(NOTE: This is the simplest form as both the numerator and the denominator do not have a common factor)
Hence, [tex]\frac{3}{5} \times \frac{4}{7}[/tex] in its simplest form is [tex]\frac{12}{35}[/tex]

(3 x 10) x 8 = x(10 x 8)
Answer:
Here you go
Step-by-step explanation:
(3 x 10) x 8 = x(10 x 8)
What you do the distributive property so multiply 3x10 and you get 30 and multiply by 8 you get 240 so one side is solved. Now multiply 10x8 you get 80 and remember to multiply the variable x so you get 80x=240 now divide 80 both sides and you will get 3 as your total answer
Answer:
3
Step-by-step explanation:
(3x10)=30
30x8=240
(10x8)=80

If the Perimeter of the triangle 15 centimeters, what is the value of n
Answer:
Step-by-step explanation:
n+2n+1+5n-6=15
= 8n + 1 - 6= 15
= 8n + 1 - 6 + 6 = 15 + 6
= 8n +1 = 21
= 8n + 1 - 1 = 21 - 1
=8n = 20
= 8n / 8 = 20 / 8
= n = 2.5
the value of ‘n’ is 2.5
The value of n in the triangle is 2.5
How to determine the value of n?The perimeter of the triangle is the sum of its side lengths.
So, we have:
P = n + 2n + 1 + 5n - 6
Evaluate the like terms
P = 8n - 5
The perimeter is 15.
So, we have:
8n - 5 = 15
Add 5 to both sides
8n = 20
Divide by 8
n = 2.5
Hence, the value of n is 2.5

His total savings, S, in x months is given by the function S(x) = 250x + 500. The function E(x) = represents Ashton’s total expenses in x months. Ashton’s expenses for 3 years total $
Answer:
E(x) = 40x² + 2150x - 500E(36) = $128740Step-by-step explanation:
Earnings = A(x)Savings = S(x)Expenses = E(x)Savings = Earnings - Expenses ⇒ Expenses = Earnings - Savings
E(x) = A(x) - S(x)E(x) = 2400x + 40x² - (250x + 500) E(x) = 2400x + 40x² - 250x - 500 E(x) = 40x² + 2150x - 500E(3 years) = E(36 months)

235 people are at RSM summer camp. There are 35 more boys than girls, and 70 fewer adults than girls. How many people of each group are at the camp?
Answer:
The number of girls are 90 girls
The number of boys are 125 boys
The number of adults are 20 adults
There are 90 girls, 125 boys and 20 adults at the camp
Step-by-step explanation:
The total number of people is given as 235 people
The number of boys = 35 + The number of girls
The number of adults = The number of girls - 70
Let the total number of girls = G
Therefore, we have;
The number of boys = 35 + G
The number of adults = G - 70
The total number of persons = The number of boys + The number of adults + The number of girls
Therefore;
235 = The number of boys + The number of adults + The number of girls
Which gives;
235 = 35 + G + G - 70 + G = 3·G - 35
235 = 3·G - 35
3·G - 35 = 235
3·G = 235 + 35 = 270
G = 270/3 = 90
The number of girls = 90
The number of boys = 35 + The number of girls = 35 + 90 = 125
The number of boys = 125
The number of adults = The number of girls - 70 = 90 - 70 = 20
The number of adults = 20.
Answer:
There are 90 girls, 125 boys, and 20 adults.
Step-by-step explanation:
Let x be the number of girls. How many boys were there?
x + 35
How many adults were there?
x - 70
We know that 235 people are at RSM summer camp. Use this to make an equation.
x + (x + 35) + (x - 70) = 235
x + x + 35 + x - 70 = 235
3x - 35 = 235
3x - 35 + 35 = 235 + 35
3x = 270
3x ÷ 3 = 270 ÷ 3
x = 90
x, x + 35, x - 70
90, 125, 20

I need help please it’s really hard and I don’t understand it
The line segment HI has length 3x - 5, and IJ has length x - 1.
We're told that HJ has length 7x - 27.
The segment HJ is made up by connecting the segments HI and IJ, so the length of HJ is equal to the sum of the lengths of HI and IJ.
This means we have
7x - 27 = (3x - 5) + (x - 1)
Solve for x :
7x - 27 = (3x + x) + (-5 - 1)
7x - 27 = 4x - 6
7x - 4x = 27 - 6
3x = 21
x = 21/3

Solve the equation for the indicated variable. A=r+rvf, for v
Answera=frv+r
Step-by-step explanationa=r+rvf
To solve for a variable in an equation means that we change the subject of the formula. The solution to the equation for variable v is:
[tex]\frac{A - r}{rf} = v[/tex]
Given that:
[tex]A = r + rvf[/tex]
Subtract r from both sides
[tex]A - r = rvf[/tex]
Divide both sides by rf
[tex]\frac{A - r}{rf} = v[/tex]
Rewrite as:
[tex]v=\frac{A - r}{rf}[/tex]
Hence, the solution to the equation for variable v is:
[tex]\frac{A - r}{rf} = v[/tex]

b. (0,6) is the point ___ of the way from R to S.
Answer:
a) (8,12) is the point [tex]\frac{3}{5}[/tex] of the way from R to S, b) (0, 6) is the point [tex]\frac{1}{5}[/tex] of the way from R to S.

Let be [tex]X[/tex] a point in the line between endpoints [tex]R[/tex] and [tex]S[/tex]. The ratio of the line segment [tex]RX[/tex] to the line segment [tex]RS[/tex] is given by:
[tex]r = \frac{RX}{RS}[/tex]
Where:
[tex]RX = \sqrt{(x_{X}-x_{R})^{2}+(y_{X}-y_{R})^{2}}[/tex]
[tex]RS = \sqrt{(x_{S}-x_{R})^{2}+(y_{S}-y_{R})^{2}}[/tex]
Let be [tex]x_{R} = -4[/tex], [tex]y_{R} = 3[/tex], [tex]x_{S} = 16[/tex] and [tex]y_{S} = 18[/tex].
a) If we know that [tex]x_{X} = 8[/tex] and [tex]y_{X} = 12[/tex], the ratio of the line segment [tex]RX[/tex] to the line segment [tex]RS[/tex] is:

[tex]RX = 15[/tex]
[tex]RS =\sqrt{[16-(-4)]^{2}+(18-3)^{2}}[/tex]
[tex]RS = 25[/tex]
Then,
[tex]r = \frac{15}{25}[/tex]
[tex]r = \frac{3}{5}[/tex]
(8,12) is the point [tex]\frac{3}{5}[/tex] of the way from R to S.
b) If we know that [tex]x_{X} = 0[/tex] and [tex]y_{X} = 6[/tex], the ratio of the line segment [tex]RX[/tex] to the line segment [tex]RS[/tex] is:
