Answer:
a.) x = 5
b.) x = 35/2 = 17.5
Step-by-step explanation:
In both problems, we are trying to solve for x, which means we need to isolate it on one side of the equation.
a.) 5/2 x + 1 = 11
5/2 x = 10
Now to divide by a fraction is the same as multiplying by the reciprocal.
x = 10 * 2/5 = 4
b.) 2/7 x - 3 = 2
2/7 x = 5
To divide by a fraction is the same as multiplying by the reciprocal.
x = 5 * 7/2 = 35/2 = 17.5

Answers
If lines and m are parallel and lines s and t are parallel. If the measure of 21 is 35°, the measure of ∠2? is : D) 145°.
Parallel lineBased on the given figure ∠1 and ∠3 form a parallel line.
Now let determine the measure of ∠2
Hence,
∠1+∠3=180 °
35° +∠3= 180 °
∠3 = 180 ° - 35°
∠3 = 145 °
The corresponding angles is ∠4 = ∠3 = 145 °
∠ 2 an ∠ 4 are as well a corresponding angles
So,
∠2 = ∠4 = 145 °

solve for z
6(x-h)=z
Answers
Answer: I hope these two answers help please mark me brainlist
Step-by-step explanation:
Simplifying
z = 6(x + -1h)
Reorder the terms:
z = 6(-1h + x)
z = (-1h * 6 + x * 6)
z = (-6h + 6x)
Solving
z = -6h + 6x
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Simplifying
z = -6h + 6x
or another answer
6(x-h)=z
Distribute 6 through the parentheses
6x-6h=z
Swap the sides of the equation
Z= 6x-6h

Answers
Answer: y= 18
Step-by-step explanation:
5y/3 = 30
First step: multiply 3 on both sides
5y/3 * 3 = 30*3
5y = 90
Second step: divide 5 on both sides (isolating variable)
5y/5 = 90/5
y = 18
Answer:
y = 18
Step-by-step explanation:
[tex]\frac{5y}{3}[/tex] = 30 ( multiply both sides by 3 to clear the fraction )
5y = 3 × 30 = 90 ( divide both sides by 5 )

The sum of two rational numbers is 4. If one of the numbers is 2/3, then what is the other number
Answers
Answer:
10/3
Step-by-step explanation:
Let x be the value of the second rational number. The first rational number is 2/3, and we are told that the sum of these numbers is 4:
x + 2/3 = 4
Therefore:
x + 2/3 = 4
x = 4 - 2/3
x = 12/3 - 2/3
x = (10/3)

According to the question:
We need to find the equation of the line:
Then,
To find the equation of the line, first, we need to find the slope of the line.
So,
From the formula of the slope of the line:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]Where,
[tex]x_1=5,y_1=7,x_2=8,y_2=12[/tex]Then,
Put all the values into the given formula:
So,
[tex]\begin{gathered} m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ m=\frac{12-7}{8-5} \\ m=\frac{5}{3} \end{gathered}[/tex]Then,
From the formula of the equation of the line:
[tex]y-y_1=m(x-x_1)[/tex]Then,
Put the value of m into the above equation:
So,
[tex]\begin{gathered} y-y_{1}=m(x-x_{1}) \\ y-7=\frac{5}{3}(x-5) \\ 3y-21=5(x-5) \\ 3y-21=5x-25 \end{gathered}[/tex]Then,

4. In the graph below, what is the line of reflection for triangle XYZ and triangle X'Y'Z"? (1 point)
the x-axis
Othe y-axis
Ox=2
Oy=2
Answers
In the graph given, the line of reflection for the triangle XYZ and triangle X'Y'Z' is x=2.
Given, the coordinates of the triangle XYZ are:
X = (4,5)
Y = (6,3)
Z = (3,2)
and the coordinates of the triangle X'Y'Z' are:
X' = (0,5)
Y' = (-2,3)
Z' = (1,2)
for image of the triangle XYZ to get reflected and become X'Y'Z',
reflection of axis takes place.
But the images are not identical and symmetrical, so the reflection is not about y axis.
we check for x=2
hence reflection of axis when x=a is :
P(x,y) →x'(2a-x , y)
therefore use the above formula and check the coordinates of the reflected image.
X(4,5) when x=2X(4,5) → X'(2(2)-4 , 5)
x(4,5) → X'(0,5)
Y(6,3) when x=2Y(6,3) → Y'(2(2)-6 , 3)
Y(6,3) → Y'(-2,3)
Z(3,2) when x=2Z(3,2) → Z'(2(2)-3 , 2)
Z(3,2) → Z'(1,2)
hence x=2 is the reflection of triangle XYZ and X'Y'Z'.
Therefore we get the requires answer.

Angles supplementary to ∠3 are ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, and ∠7.
What are supplementary angles?Two angles are considered to be supplementary if their sums total 180 degrees. If two angles in geometry add up to 180 degrees, they are said to be supplementary angles. For instance, A and B are referred to as supplementary angles if A + B = 180°. When combined, supplementary angles always make a straight angle (180 degrees).So, angles supplementary to ∠3:
∠1 is supplementary to ∠3 (Straight angle)∠2 is supplementary to ∠3 (Inversely opposite angle)∠4 is supplementary to ∠3 (Straight angle)∠5 is supplementary to ∠3 (Adjacent angles)∠6 is supplementary to ∠3 (Alternate angles)∠7 is supplementary to ∠3 (Corresponding angle)(Refer to the image attached below)

It is a number ranging from -1 to 1 that indicates the strength and direction of a link between two variables. When one variable shifts, the other shifts in the same way.
Positive correlation is graded on a scale of 0.1 to 1.0. Weak positive correlation would be between 0.1 and 0.3, moderate positive correlation between 0.3 and 0.5, and strong positive correlation between 0.5 and 1.0.

The ratio of bream to tench to carp is given by the expression; 12 : 7 : 21
What is a ratio of items?A ratio is a relationship between two or more items, that quantitatively expresses the number of times a unit item can be found within the quantity of each item in the set of items.
The given parameters are;
Number of fish in the pond = 40
The number of fish in the pond that are bream = 12
The number of fish that are tench = 1/4 of the fish that are not bream
The number of the fish that are carp = The rest of the fish that are not bream or carp
Required;
The ratio of bream to tench to carp of the fish in the pond.
Solution;
The number of fish that are either tench or carp = 40 - 12 = 28
The number of the fish that are tench = (1/4) × 28 = 7
Therefore;
The number of fish that are carp = 28 - 7 = 21
Which gives;
Number of bream in the pond = 12
Number of tench in the pond = 7
Number of carp in the pond = 21
The ratio of the number of bream to tench to carp in the pond is given by the expression;
[tex]\displaystyle{ \frac{12}{40}:\frac{7}{40}:\frac{21}{40}}[/tex]
