Answer:
a=20
Step-by-step explanation:
4a+8-2a-3=45
-8 on both sides
4a-2a-3=37
+3 on both sides
4a-2a=40
2a=40
a=20
Answer:
a = 20
Step-by-step explanation:
Let's understand it quickly,
4a + 8 - 2a - 3 = 45
Gather the like terms on RHS and LHS,
4a - 2a = = 45 - 5
2a = 40
a = 40/2
a = 20

Which rational number is positive
Taylor and Alex are looking for a daycare for their child. They want to make sure the daycare is midway between their jobs. Taylor works at the Rogers Middle School located at (4, -5), and Alex works at St. Philip's located at (2, 5). Where should the daycare be located?
The location of the coordinate of the daycare is (3, -1.5)
Midpoint of coordinatesThe formula for calculating the midpoint of coordinate is expressed as;
M(x, y) = {(x₁+x₂/2, y₁+y₂/2)}
Given the coordinate points (4, -5) and (2, 5), on substituting, we will have:
M(x, y) = {(4+2/2, -5+2/2)}
M(x, y) = (6/2, -3/2)
M(x, y) = (3, -1.5)
Hence the location of the coordinate of the daycare is (3, -1.5)

Answer: The student is wrong because you have to figure out the area of each of the rectangles to find the total area. Add each of the areas to get your answer.
Step-by-step explanation:
Answer:
the total area is 1400
Step-by-step explanation:
The student is wrong. The shape's area can be calculated.
If you divide the shape into 3 separate rectangles horizontally
1st: area = 35 x 10 = 350
2nd area = 10 x 60 = 600
3rd area = (60 - 15) x 10 = 450

np bisects MNQ, measurement MNQ, measurement MNP = (6X-12)° and measurement PNQ = (4x+8)°. find measurement MNQ
The Required answer is ∠MNQ is (10x - 4)°
Two unique points on a line define the boundaries of a line segment. A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction.
Given NP bisects MNQ as shown in the given figure
A line segment that bisects two lines divides them into two equal parts.
Given ∠MNP =( 6x - 12)°
Given ∠PNQ = (4x + 8)°
We have to determine ∠MNQ as
∠MNQ = ∠MNP + ∠PNQ

Answer:
Step-by-step explanation:
The measure of one angle is four times the measure of its supplement. Find the measure of each angle.
The measure of the angle is 36° and its supplement is 144°.
The supplement of an angle is calculated by subtracting the value of the angle from 180°.
A linear pair of angles are supplement of one another.When two straight lines intersect at a point then any 2 adjacent angle of the four angles formed are supplementary angles. In a cyclic quadrilateral ( quadrilateral whose 4 sides touch the same circleat different points ) opposite angles are supplementary.Given that the supplement of the angle is 4 times the angle.
Let us consider the value of the angle be x°.
Therefore the value of the supplement is 4x°
Now the sum of the two supplementary angles is 180°.
∴x° + 4x° = 180°
or, 5x° = 180 °
or, x° = 36°
Therefore the larger angle = 4x° = 4 × 36° = 144° .
Hence the angles are 36° and 144° .

A survey of 279 SPC students was taken at registration. Of those surveyed: 51 students had signed up for a Language Arts course 36 students had signed up for a Humanities course 18 students had signed up for both a Math and Language Arts course 8 students had signed up for both a Math and Humanities course 9 students had signed up for both a Language Arts and Humanities course 4 students had signed up for all three courses students did not sign up for any of these classes How many students signed up for only Math (of these three)?
Treating the amounts as Venn sets, we have that 161 students signed up for only Math, considering that 40 did not sign for any.
What are the Venn sets?For this problem, we consider the following sets:
Set A: Students that have signed up for Arts.Set B: Students that have signed up for Humanities.Set C: Students that have signed up for Math.4 students had signed up for all three courses students, hence:
(A ∩ B ∩ C) = 4.
8 students had signed up for both a Math and Humanities, hence:
(B ∩ C) + (A ∩ B ∩ C) = 8
(B ∩ C) = 8.
18 students had signed up for both a Math and Language Arts, hence:
(A ∩ C) + (A ∩ B ∩ C) = 18
(A ∩ C) = 14.
9 students had signed up for both a Language Arts and Humanities, hence:
(A ∩ B) + (A ∩ B ∩ C) = 9
(A ∩ B) = 5.
36 students had signed up for a Humanities course, hence:
B + (A ∩ B) + (B ∩ C) + (A ∩ B ∩ C) = 36
B + 5 + 8 + 4 = 36
B = 19.
51 students had signed up for a Language Arts course, hence:
A + (A ∩ B) + (A ∩ C) + (A ∩ B ∩ C) = 36
A + 5 + 14 + 4 = 51
A = 28.
Considering that there are 279 students, and supposing 40 did not sign for any course, we have that:
A + B + C + (A ∩ B) + (B ∩ C) + (A ∩ C) + (A ∩ B ∩ C) + 40 = 279.
28 + 19 + C + 5 + 8 + 14 + 4 + 40 = 279
118 + C = 279
C = 161

The number of sweaters that Jaylen will purchase, based on his marginal benefit, is 5 sweaters.
What is marginal utility?Marginal utility or benefit is the added satisfaction that a consumer derives from the consumption of an additional unit of a product or service.
Using the concept of marginal utility, we can determine the number of units consumers will be willing to purchase.
The law of marginal utility states that a consumer will continue to purchase more of an item until their marginal benefit or utility is fewer than the cost of the item.
For instance, Jaylen will buy sweaters until his marginal benefit is lower than the price of a sweater ($10).
Jaylen is likely to buy 5 sweaters since his marginal benefit, though progressively reducing, still exceeds the price of the sweaters.
Data:Price per sweater = $10
Marginal Benefits
1st sweater 50
2nd sweater 35
3rd sweater 30
4th sweater 23
5th sweater 12
6th sweater 8
Thus, based on marginal utility, Jaylen will purchase 5 sweaters.

Set y = 0 in y=-x2²-4x-3.
O Factor each side of the equation.
Use substitution to create a one-variable equation.
O Combine like terms onto one side of the equation
Answer: The first step in determining the solution to the system of equations algebraically is [-4,-2].
Step-by-step explanation:
Determining the solution to the system of equations,
so, y=-x²-4x-3 and y= 2x+5, algebraically is to set the two equations are equal to:
-x²-4x-3 =2x+5
Then the solve in this equation
To put all terms into the lest side of the equation and group the terms:
solve it: -x²-4x-3-2x-5=0
-x²+(-4x-2x)+(-3-5)=0
-x²-6x-8=0

A fraction is a way to describe a part of a whole. Beth will able to fill 5 complete bottles from a single batch of liquid cleaner.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given that the recipe makes ⅔ gallons. Also, Beth puts cleaner in ⅛ gallon bottles. Therefore, we can write,
Total batch size = ⅔ gallons
Size of a bottle = ⅛ gallon
Now, the number of bottles that Beth will be able to feel from a single batch of liquid cleaner is,
Number of bottles = Total batch size / Size of a bottle
= ⅔ gallons / ⅛ gallon
= (2×8) / (3×1)
= 16 / 3
