Answer:
x = 7
Step-by-step explanation:
The corresponding sides are proportional:
(2x +1)/5 = (x +2)/3
3(2x +1) = 5(x +2) . . . . . cross multiply
6x +3 = 5x +10 . . . . . . . eliminate parentheses
x = 7 . . . . . . . . . . . . . . . subtract 5x+3 from both sides

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).
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

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

plz mark brainliest
Step-by-step explanation:
l= 3w
perimeter = 2(l+w) =2(3w+w) = 2(4w)= 8w

w=32/8 =4 inches
l= 3(4) =12 inches
area = l×w = 12×4 = 48 square inches

The width of a rectangle, in centimeters, is 17 less than 4 times its length, in centimeters. The area
of the rectangle is 15 square centimeters. What is the width, in centimeters, of the rectangle?
Answers
Answer:
Step-by-step explanation:
W = 4L-17
LW = 15
L(4L-17) = 15
4L^2-17L-15= 0
L = [17 ±√(17^2-4(4)(-15))]/[2(4)] = 5,-3/4
-3/4 is an extraneous solution
L = 5 cm
W = 4L-17 = 3 cm

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.
