Answer:
2. Open the bracket
Step-by-step explanation:
1. Given:
[tex]3(x + 2) = 12[/tex]
2. Open the bracket, by multiplying 3 on every term in the bracket.
[tex] (3 \times x) + (3 \times 2) = 12 \\ 3x + 6 = 12[/tex]
3.Subtraction Property of equality:
[tex]3x + 6 - 6 = 12 - 6[/tex]
4. Simplify:
[tex]3x = 6[/tex]
5. Divide property of equality:
[tex] \frac{3x}{3} = \frac{6}{3} [/tex]
6. Simplify:
[tex]x = 2[/tex]

determine the area of the triangular ABC with AC =5cm and height DB=30mm
Answer:
Step-by-step explanation:
AC² = AD² + DB ²
25 = AD² + 9
AD²= 25 - 9
AD² = 16
AD = 4
Area = 4*3 /2
= 6cm
sunayana thought of number. She trebled it and subtracted 7 from it. If she got 8, find the number she thought of.
Answer:
Number she thought = 5
Step-by-step explanation :
-The number sunayana took :- x
- The number after she trebled it :- 3x
So,
-3x - 7 = 8
= 3x = 7 + 8
= 3x = 15
= x = 15 / 3
= x = 5

What is an equation of the line that passes through the points (-6, -4) and (3, 8)
Answer:
y = [tex]\frac{4}{3}[/tex] x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, - 4) and (x₂, y₂ ) = (3, 8)
m = [tex]\frac{8-(-4)}{3-(-6)}[/tex] = [tex]\frac{8+4}{3+6}[/tex] = [tex]\frac{12}{9}[/tex] = [tex]\frac{4}{3}[/tex] , then
y = [tex]\frac{4}{3}[/tex] x + c ← is the partial equation
To find substitute either of the 2 points into the partial equation
Using (3, 8 ) , then
8 = 4 + c ⇒ c = 8 - 4 = 4
y = [tex]\frac{4}{3}[/tex] x + 4 ← equation of line
According to the histogram, there are two possible values for the maximum number of hours studied. What are they?
Answer:
15
Step-by-step explanation:
because most children like to spend time and other children like an to not spent time on studying
The two possible values for the maximum number of hours studied are 6 hours and 8 hours.
Given,
A histogram with the number of hours on the x-axis and frequency on the y-axis.
We need to find the two possible values for the maximum number of hours studied.
What is a frequency?Frequency means the number of times an event occurs.
Example:
A, B, and C choose green balls.
D, E, M, and N choose red balls.
The frequency that a green ball is chosen is 3.
The frequency that a red ball is chosen is 4.
We have,
The histogram where the bar with the highest frequency is at 15 on the y-axis and the bar is between 6 to 8 hours on the x-axis.
So, we can say that the two possible values for the maximum number of hours studied are 6 hours and 8 hours.
Thus the two possible values for the maximum number of hours studied are 6 hours and 8 hours.

Answer:
64w^2
Step-by-step explanation:
Because 8w is in parentheses, you must apply the exponent to both the 8 and w.
So, it becomes (8*8)(x*x) which equals (64)(x^2).
Which then gives you your final answer, 64x^2.

Solve for n in the literal equation a(n − 5) + 6 = bn.
Answer:
(6-5a)/(b-a) = n
Step-by-step explanation:
a(n − 5) + 6 = bn
Distribute
an -5a +6 = bn
Subtract an from each side
an -5a+6 -an = bn-an
6-5a = bn-an
Factor out n
6-5a = n(b-a)
Divide each side by (b-a)
(6-5a)/(b-a) = n
Answer:
[tex]a(n - 5) + 6 = bn \\ an - 5a + 6 = bn \\ an - bn = 5a - 6 \\ n(a - b) = 5a - 6 \\ n = \frac{5a - 6}{a - b} \\ thank \: you[/tex]

I need help please :)))) I don't understand how to do it. Thank you ! :))))
Step-by-step explanation:
supplement means their addition is equal to 180°
since m<x and m<y are supplement then m<x+m<y=180
and <y supplement to <z (their addition equals to 180°)
since m<y and m<z are supplement then m<y+m<z=180
m<x+m<y= m<y+m<z
m<y cancelled
m<x= m<z
_________________
FOR EXAMPLE
Given that <x and <y are supplement
and <y and <z are supplement
if <x= 45°
that means that <y = 135°
so that <x +<y = 180°
45+135= 180 ✓
and <y and <z are supplement
m<y+ m<z = 180°
then m<z= 45°
m<x+m<y= m<y+m<z
m<x +135= 135+m<z
then m<x= m<z = 45°

Step-by-step explanation:
AB = AW + WB
But AW also equals WB because of the bisecting point
x + 6 = 3x
6 = 2x
x = 3
AW = 3 + 6 = 9
WB = 3(3) = 9
9 + 9 = 18°

State the type of graph that is characteristic of velocity with depth
Graphs and functions are used to show relationships between variables.
The term "graph" as used in this question represents functions. There are several types of functions, some of them are:
LinearPowerQuadraticPolynomialThe question is incomplete, so I'll give a general explanation of how to identify the graph
Linear function:
This is represented by a straight line, and the equation is [tex]y = mx + b[/tex]
Power function
This is when a variable is raised to the power of a fixed number. It is represented as: [tex]y = x^n[/tex]
Quadratic Function
A quadratic function has the form: [tex]y = ax^2 + bx + c[/tex]
Polynomial function
A polynomial function is a function where the exponents of the variable are non-negative. The form of a polynomial function is: [tex]y = ax^m + bx^{m-1} + cx^{m-2} + ........ + d[/tex]
There are several other functions (sinusoidal, constant, inverse, rational functions, etc.)
Compare the missing graph of this question to the attached graphs (see attachment), to determine the graph type.
