Solve the equation for b
Answer:
b=7a
Step-by-step explanation:
11a+b/3=6a
or, 11a+b=6a*3( when there is divide in one side it will be multiply when it is in another side)
or, 11a+b=18a(multiplying the number)
or, b=18a-11a( when there is + sign in one side it will be - sing in another side )
or, b=7a
A piece of chocolate is 4/5 inch long. Meg lays 4 chocolate pieces end to end in a row. How many inches long is the row of chocolates ( please helpppppp) ( MAP test question)
Answer:
The length of row = 3.2 inches.
Step-by-step explanation:
The length of a chocolate = 4/5 inch
Total number of chocolate pieces placed = 4
Now we have given the length of one chocolate and it is required to find the total length of the row when four chocolates are placed end to end. So in order to find the length of the chocolate row we have to multiply the size of one chocolate by the number of chocolates.
The length of row = Length of one chocolate × number of chocolates
The length of row = 4/5 × 4
The length of row = 3.2 inches.
The piece of chocolate and the number of chocolates in a row can be represented using equations.
A row of chocolate is 3.2 inches long
Given that:
[tex]L = \frac 45[/tex] ---- Length of a piece
[tex]n =4[/tex] --- number of chocolate pieces
The length of the chocolate in a row is calculated as follows:
[tex]Length = n \times L[/tex]
So, we have:
[tex]Length = 4 \times \frac 45[/tex]
[tex]Length = 4 \times 0.8[/tex]
[tex]Length = 3.2[/tex]
Hence, a row of chocolate is 3.2 inches long

Answer:
x = 1.5
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask :)
The solution of the equation, (3/2)·(4·x - 2) - 3·x = 5 - (x + 2) is; x = 1.5
What is an equation?An equation is a mathematical statement indicating equivalence between two expressions.
The equation (3/2)·(4·x - 2) - 3·x = 5 - (x + 2) can be solved step by step as follows;
Distributing the (3/2) on the left hand side, we get; (3/2)·4·x - (3/2)×2 - 3·x = 5 - (x + 2)Simplify the left hand side; 6·x - 3 - 3·x = 5 - (x + 2)Combine like terms on the left hand side; 3·x - 3 = 5 - (x + 2)Distribute the -1 on the right hand side; 3·x - 3 = 5 - x - 2Combine like terms on the right hand side; 3·x - 3 = 3 - xAdd x to both sides; 4·x - 3 = 3Add 3 to both sides; 4·x = 6Divide both sides by 4; x = 6/4Therefore, the solution of the equation is; x = 6/4, or x = 1.5

The area of the trapezoid FGHJ is 33 square units.
Given that, trapezoid FGHJ has vertices at F(2.-3), G(2, 4), H(6,4), and J(19, -3).
We need to find the area of the trapezoid.
What is the formula to find the area of trapezium?The area of a trapezium is defined as the number of unit squares that can fit into it and it is measured in square units (like cm², m², in², etc). A trapezium is a type of quadrilateral that has one pair of parallel sides(generally referred to as bases). The other pair of sides of a trapezium can be non-parallel and are known as legs. The area of a trapezium is the total space covered by a trapezium in a two-dimensional plane.
The area of a trapezium =1/2 (a+b)×h square units.
Now, area=1/2 (4+17)×6=33 square units
Therefore, the area of the trapezoid FGHJ is 33 square units.

A figure is located entirely in the third quadrant. If you reflect it over y = 0. Which quadrant will the resulting figure lie in?
Answer: Quadrant 2
=================================================
Explanation:
Check out the diagram below. An example point in the third quadrant is (-2,-5). This quadrant is the southwest quadrant. Reflect the example point over the x axis (aka the line y = 0) and we get (-2,5). This is shown when we go from point A to point B in the diagram.
The reflection rule is [tex](x,y) \to (x,-y)[/tex] showing that only the y coordinate changes from y to -y. If y is negative, then flip to positive, or vice versa. The x coordinate stays the same.
The point started in quadrant 3 and it moves to quadrant 2 after the reflection over the line y = 0.
Side note: all points on the line y = 0 have a y coordinate of 0

victora took a test and got 80 percent of her question right and anwserd 20 question correctly how many question are on the test
Answer:
25 questions
Step-by-step explanation:
First set up the equation.
[tex]\frac{20}{x} = \frac{80}{100}[/tex]
To get from 20 to 80 you have to multiply by a scale factor of 4, so do the same to the bottom as well.
Do the inverse and divide 100 by 4 to get x = 25.
There were 25 questions on Victoria's test.

25
Step-by-step explanation:
because 5 x 10 is 50 so 5 x 16 is 80 so she got an 80 but 5x 20 equals 100 so Victoria got 5 points per questions so multiply and youll find out i has to be 25 tho
