mother gave her marbles for
her birthday. Virginia lost 13
of them. If she has 24 marbles
left, write and solve an
equation to find how many her
mother gave her.
Answers
Answer:
37
Step-by-step explanation:
If she has 24 left, and lost 13, you add 13 and 24 to find the original amount.
Virginia's mother gave her 37 marbles for her birthday.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
Virginia's mother gave her marbles for her birthday.
Let number of marbles = x
Here, Virginia lost 13 of them and she has 24 marbles left.
So, We get;
⇒ x - 13 = 24
Solve for x;
⇒ x = 24 + 13
⇒ x = 37
Thus, Virginia's mother gave her 37 marbles for her birthday.

x = - 1
Step-by-step explanation:
y = 4x + 3
y = -x - 2
Find x:
4x + 3 = -x - 2
5x + 3 = - 2 (Adding x to both sides)
5x = - 5 (Subtracting 3 from both sides)
x = -1 (Dividing 5 from both sides)

w=32/8 =4 inches
l= 3(4) =12 inches
area = l×w = 12×4 = 48 square inches
what is the surface area of this shape?
Answers
Answer:
361.88 in.²
Step-by-step explanation:
Surface area of triangular prism = 2(B.A) + PH
Where,
B.A = base area of triangular base = ½*bh = ½*8*6 = 24 in.²
P = perimeter of triangular base = 7.21 + 7.21 + 8 = 22.42 in.
H = height of the prism = 14 in.
Surface area of the prism = 2(24) + 22.42×14
= 48 + 313.88
= 361.88 in.²

I KNOW SPEAK SPANISH GO TO A MEXICAN SITE NOT A AMERICAN SITE
x=5
y=52
since AB and BC are the same length, you know it is an isosceles triangle
so two of the angles are the same
angle A and angle C are the same
so y = 52
A = C :. y = 52
all angles of a triangle add to 180
so add 52 and 52 to get 104
subtract 104 from 180 to get 76
set 14x + 6 = 76
14x = 70
x = 5

HELP AGAIN PLEASE 20 POINTS What methods can be used to solve a system of equations and when would you use each? Be sure to include systems with nonlinear equations.
Answers
Answer:
The three ways to solve a system of equations are substitution, elimination, and graphing. You can use these methods to solve any system of equations, it just depends on which method you use.
Step-by-step explanation:
In the substitution method, you get one variable isolated on one side of an equation, then use that equation to substitute the variable with what it's equal to into the second equation to solve the equation.
In the elimination method, you get all the variables in your equations together one side, and the constant on the other. Then, multiply or divide one or two equations to get one variable with the same coefficient for both equations (be sure to multiply or divide both sides to each equation), and add or subtract the equations together to get rid of that variable (make sure to add the left sides of the equations together and the right sides of the equations together, no the opposite!) and solve the equation.
In the graphing method, you solve for y in each equation, graph both equations on a coordinate plane, and find the point of intersection for both lines to solve the equation (For example, if the point of intersection is (2, 7), the answer to your equation would be X = 2 and Y = 7).

Answers
Answer:
77.5 degrees and 102.5 degrees
Step-by-step explanation:
Given that : one angle is25 degrees greater than another. Let the two angles be represented by a and b. Since one angle is 25 degreess greater than another, then:
b = a + 25 degrees
But;
a + b = 180 degrees (sum of angles on a straight line)
a + a + 25 degrees = 180 degrees
2a = 180 degrees - 25 degrees
a = 77.5 degrees
b = 77.5 degrees + 25 degrees = 102.5 degrees
Therefore the measures of all angles formed by the lines is either 77.5 degrees or 102.5 degrees.

Solve the system using the substitution method
x = -6y - 4
6x - 12y = 24
Answers
Answer:
x = 2, y = -1
Step-by-step explanation:
We have a solution system, x = -6y - 4 and 6x - 12y = 24.
Now, since are not only asked to use the substitution method, but at the same time know the value of x, let's plug the first system into the second.
x = -6y - 4
6(-6y - 4) - 12y = 24
-36y - 24 - 12y = 24
-48y - 24 = 24
Add 24 to both sides :
-48y = 48
Divide -48 by both sides :
y = -1
Now that we have y, we can replace it into the second system again to get x.
6x - 12(-1) = 24
6x + 12 = 24
Solve for x by first getting rid of 12 from both sides :
6x = 12
Divide 6 by both sides :
x = 2
Therefore, x = 2 and y = -1
