Jaylin's test grades in History class → 92, 89, 85, 89 and 90
Let the marks achieved in the final semester = x
Total marks achieved = 92 + 89 + 85 + 89 + 92 + x
= 447 + x
Minimum or the average marks required in 6 semester = 90
Total marks required in 6 semesters = 90×6
= 540
447 + x = 540
x = 540 - 447
x = 93
Therefore, Jaylin should achieve minimum 93 marks in the last semester.

Leah scored a total of 18 points in the basketball game, and she scored p points in the second half of the game. Write an expression to determine the number of points she scored in the first half of the game. Then, find the number of points she scored in the first half of the game if she scored 2 points in the second half of the game.
Answer: 16 points for the first half game
Step-by-step explanation:
1st half = ?
2nd half= p
Total = 18
The expressions to get the score of the 1st game is 18 -p
If she scored 2points in the second half game that means p=2
To get the 1st half of the game you should do 18-2=16
Help please.. for my sister .... I’m older and I don’t get this
Answer: C. Point M
Step-by-step explanation:
There are 10 tick marks. The tick marks could be guessed to be 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.50. 1/3 as a decimal is 0.33. The point should be between the(6th tick mark) 0.3 and (7th tick mark) 0.35 based on the assumed tick marks. Looking at the number line, the point that is between the 6th and 7th tick mark is M. Therefore, the answer is Point M.14 + x = -9 What is the answer?

The midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8), what are
the coordinates of B?
Answer:
Step-by-step explanation:
(x - 3)/2= 1
x - 3 = 2
x = 5
(y - 8)/2 = -2
y - 8 = -4
y = 4
(5, 4) coordinates for B
The coordinates of B are (5, 4) if the midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8),
What is an ordered double?It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).
[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]
It is given that:
The midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8).
Let the coordinate of B is (x, y)
From the midpoint theorem:
(x - 3)/2= 1
x - 3 = 2
x = 5
For y coordinate:
(y - 8)/2 = -2
y - 8 = -4
y = 4
(5, 4) coordinates for B
Thus, the coordinates of B are (5, 4) if the midpoint of AB is M(1,-2). If the coordinates of A are (-3, -8),

Solve the equation 5x+(-2)=6x+4
Answer:
x = -6
Step-by-step explanation:
Step 1: Write out equation
5x + (-2) = 6x + 4
Step 2: Simplify
5x - 2 = 6x + 4
Step 3: Subtract 5x on both sides
-2 = x + 4
Step 4: Subtract 4 on both sides
-6 = x
Step 5: Rewrite
x = -6
Answer:
x = -6
Step-by-step explanation:
[tex]5x+(-2)=6x+4[/tex]
Open the parenthesis
[tex]+(-2) =-2\\\\5x -2 =6x+4[/tex]
Collect like terms and simplify

Balloon A is released 5 feet above the ground. Balloon B is released at ground level. Both balloons rise at a constant rate. Which situation can you represent using an equation of the form y = kx? Explain.
Answer:
The situation of balloon B
Step-by-step explanation:
Balloon A is released 5 feet above the ground and our ground level be 0 feet. Let k be the rate at which it rises and t the time it takes to rise. Its height y, above the ground after time x is y = kt + 5
For Balloon B since it is released at ground level at which ground level is taken as 0 feet, let t be the time it takes to rise above the ground and k the rate at which it rises above the ground. Its height y above the ground after tie x is y = kt
Since the expression for Balloon B is y = kt and the expression for Balloon A is y = kt + 5, only the situation of Balloon B can be expressed in the form y = kx.
This is because the rate of rise of Balloon B follows a direct proportionality while the rate of rise of Balloon follow a joint proportionality since it starts from a point other than ground level.

*Instead of rewriting PF to QF +43 in part (a), you could also leave PF as it is and rewrite QF as PF -43 after the line I labelled as equation 2. The working would be about the same, just that you would not need to add 43 again in picture 3 because we would be working with PF. (PF would be factorised out instead)

[tex]3(m - 5) + 11 = - 85[/tex]
Answer:
Bro this some alien hyroglyphics
Step-by-step explanation:
Answer:
m = - 27
Step-by-step explanation:
Given
3(m - 5) + 11 = - 85 ← distribute and simplify left side
3m - 15 + 11 = - 85
3m - 4 = - 85 ( add 4 to both sides )
3m = - 81 ( divide both sides by 3 )
m = - 27
Find the measure of an angle if its measure is 26 degrees more than three times its compliment?
16
141
74
42
The complement = x
The angle we are finding = 3x + 26
Complementary angles are angles that add up to 90 degrees.
90 = x + 3x + 26
Combine like terms
90 = 4x + 26
Subtract 26 from both sides
64 = 4x
Divide both sides by 4
16 = x
The angle we are trying to find = 3(16) + 26 = 48 + 26 = 74 degrees

Answer:
B I believe
Step-by-step explanation:
A line passes through the points (3,7) and (5,19) Part A: find the slope
Part B: what is a possible equation of a line parallel to the line through (3,7) and (5,19)
Y=mx + b
Answer:
The slope is 6. For the first line you could do y=6x+7, and the line parallel to that could be y= 6x+3
Step-by-step explanation:
For it to be parallel the slopes have to be the same and the y intercepts (b) have to be different. And I found the slope by doing y-y/x-x
