Answer: The number is 1
Step-by-step explanation:
5x + 7 = 9x + 3
5x + 7 - 5x = 9x - 5x + 3
7 = 4x + 3
7 - 3 = 4x + 3 - 3
4 = 4x
x = 1
Check work:
5(1) + 7 = 12
9(1) + 3 = 12
It works

Given isosceles right triangle CDE with m∠D = 90, sin C = sin D
Answer:True
Step-by-step explanation:
Given
[tex]\angle D=90^{\circ}[/tex]
For isosceles triangle , CD=DE (x=y)
from figure,
[tex]\sin C=\dfrac{y}{H}\\\\\sin D=\dfrac{x}{H}\\\\\text{CD=DE}\\\\\therefore \sin C=\sin D=\dfrac{x}{H}=\dfrac{y}{H}[/tex]
Thus, the given statement is true
In a maths class the girl to boy is 7:5 If there are 20 boys how many girls are in the class
Answer:
Let the total no of girls be x
the number of boys=7:5
total no of students =20
now,
no of girls =7/5=x/20
or, 20*7=5x
or 140=5x
or,x=140/5=28
therefore the number of girls =28
what's is m when u are looking for x or y intercept
Answer:
Slope.
Step-by-step explanation:
mx+b
Answer:
Slope
Step-by-step explanation:
The equation of lines are normally formatted in "slope-intercept form"
(y = mx + b)
The b in the equation would be the y-intercept of the line.
The m represents the slope.
The x and y can be replaced with any x and y value from the line (if necessary)
Which function rule for points would create the translation shown above?
(x, y) + (x+4, y+3)
(x, y) + (x-4, y-3)
(x, y) + (x+10, y+7)
(x, y) + (x-10, y-7)
Answer:
Option A
Step-by-step explanation:
Coordinates of the given points A and A',
A → (-6, -2)
A' → (-2, 1)
Rule for the translation of point A to A',
A(-6, -2) → A'(-6+h, -2+k)
Since, coordinates of A' are (-2, 1)
Therefore, -6 + h = -2
h = 6 - 2 = 4
And (-2 + k) = 1
k = 3
Therefore, rule for the translation will be,
(x, y) → (x + 4, y + 3)
Option A will be the answer.

when

find,
y
when
x
=
225
Answer:
y = 75
Step-by-step explanation:
Given that:
y [tex]\alpha[/tex] [tex]\sqrt{x}[/tex]
⇒ y = k[tex]\sqrt{x}[/tex]
where k is the constant of proportionality.
When y = 45, x = 81, then;
45 = k[tex]\sqrt{81}[/tex]
45 = 9 k
k = [tex]\frac{45}{9}[/tex]
= 5
k = 5
So that,
y = 5[tex]\sqrt{x}[/tex]
the value of y when x = 225 is;
y = 5[tex]\sqrt{x}[/tex]
= 5 x [tex]\sqrt{225}[/tex]
= 5 x 15
y = 75

Barton has 4 strawberries and Ona has 8. If they want to redistribute their strawberries so they each have an equal number, how many strawberries should Ona give to Barton? There are a total of strawberries. There are a total of people. The expression to find the mean, or balance point, is . should give 2 strawberries to for the number of strawberries to be balanced.
Answer:
2 strawberries
Step-by-step explanation:
Given that:
Number of strawberries :
Ona has 8
Barton has 4
For both Ona and Barton to have the same Nunber of strawberries :
(Ona + Barton) /2 = (8 + 4) / 2 = 12 /2 = 6
That means both Ona and Barton will have 6 strawberries each
Hence,
Barton who has 4 strawberries needs 2 more while Ona who has 8 will give out 2
Hence, Ona should give two strawberries to Barton.
Answer:
total strawberries 12
total 2 people
expression to find the mean 12/2
ona should give barton 2 strawberries so the number balance's out

A random sample of students were asked whether they prefer milk juice or water is it results are summarized in the table.
Answer:
C
Step-by-step explanation:
The probability of students response is milk is 0.311.
What is probability?Probability deals with the occurrence of a random event. The chance that a given event will occur. It is the measure of the likelihood of an event to occur.The value is expressed from zero to one.
For the given situation,
The table shows the students preference of milk, juice or water.
Total number of students preferred milk = 14
Total number of students = 45
Thus the probability that the students response is milk is
[tex]P(e)=\frac{14}{45}[/tex]
⇒ [tex]P(e)= 0.311[/tex]
Hence we can conclude that the probability of students response is milk is 0.311.

Step-by-step explanation:
Answer:

Step-by-step explanation:
Hello There!
First things first, we should find the rate of change / slope
given two points we can find the slope by using the slope formula which is
(let m be slope)
[tex]m = \frac{y_2-y_2}{x_2-x_2}[/tex]
To find the slope all we have to do is plug in the points
(1,5),(2,10)
remember the first numbers in an ordered pair are the x values and the second numbers are the y values
we also plug in the points of the second ordered pair first so
[tex]m=\frac{10-5}{2-1} \\10-5=5\\2-1=1\\m=\frac{5}{1} or5[/tex]
Knowing the slope we can create an equation to find the x value (a)
y=5x
given the y value we plug in y and solve for x
15=5x
divide each side by 5
15/5=3
5x/5=x
we're left with
x=3
so we can conclude when y =15 x = 3 therefore 3 is your answer
