The sum of three numbers is 109. The second number is 4 times the first number and the third number is 8 less that the second number. What are the three numbers?
Answer:
I think the answers are 19, 17 and 76.
I am not sure...
a 27-inch board is to be cut into three pieces so that the second piece is 3 times as long as the first piece and the third piece is 5 times as long as the first piece. if x represents the length of the first piece, find the lengths of all three pieces
Step-by-step explanation:
27 = x + 3x +5x
27 = 9x
3 = x
Board 1: (3)(1) = 3 inches
Board 2: (3)(3) = 9 inches
Board 3: (3)(5) = 15 inches
Length of the first piece is 3 inches
Length of the second piece is 9 inches
Length of the third piece is 15 inches
What are equations?An equation is a mathematical statement which equate two algebraic expressions. An equation has an equal to (=) sign in between the expression.
How to find the lengths of all three pieces?According to the problem,
The length of the board is 27 inches.The board is to be cut into three pieces .The second piece is 3 times as long as the first pieceThe third piece is 5 times as long as the first piece.x represents the length of the first piece∴ Length of the second piece = 3x inches
∴ Length of the third piece = 5x inches.
Now, all these pieces will add up to 27 inches.
∴ x + 3x + 5x = 27
⇒ 9x = 27
⇒ x = 3
Length of the first piece = 3 inches
Length of the second piece = (3 x 3) inches = 9 inches
Length of the third piece = (5 x 3) inches = 15 inches

AC CE and D is the midpoint of CE. IF CE 10x + 18, DE =7x -1, and BC = 9x - 2, find AB, AB =
Answer:
If you mean: AC=CE, the answer is: AB = 24Step-by-step explanation:
D is the midpoint of CE, then
CD = DE = 0.5CE = 0.5(10x+18) = 5x + 9
So: 5x + 9 = 7x - 1
-9 -9
5x = 7x - 8
-7x -7x
-2x = -8
÷(-2) ÷(-2)
x = 4
AC = CE = 10x + 18 = 40 + 18 = 58
BC = 9x - 2 = 36 - 2= 34
AB = AC - BC = 58 - 34 = 24
D is the midpoint of CE, so if you draw a line with those three points, it'll look like C-D-E.
Since DE = 7x-1, which also means CD = 7x-1.
CD + DE = CE, so (7x-1)+(7x-1) = 10x+18.
Therefore, x = 5 and CE = 68.
Since AC is congruent to CE, AC = 68.
Assuming the point B is somewhere between AC.
Since BC = 9x-2 and x = 5, which means BC = 43.
AC - BC = AB, so 68 - 43 = 25.
Therefore, AB = 25

-2(6m + 5) = -5m + 18
solve for m
Answer:
m =-4
Step-by-step explanation:
-12m-10=-5m+18
add 5m to both sides
-7m-10=18
add 10 to both sides
-7m=28
divide both sides by -7
m= -4
Answer: m = -4
Step-by-step explanation: First distribute to get -12m -10 = -5m+18, then add 5m on both sides to get -7m -10 = 18, then add 10 on both sides to get -7m = 28, finally divide by -7 on both sides to get m = -4.

1. What is the solution for 2x-5=7
O x = 6
O x = -6
X = 12
O x = 9
Given, equation in the question which we have to solve is
[tex]2x - 5 = 7[/tex]
Here, we need to find x. So, Let's isolate x on one side of the equation. It is present in the left hand side. Add 5 to both sides,
[tex]2x - 5 + 5 = 7 + 5[/tex]
[tex]2x = 12[/tex]
Divide 2 from both sides,
[tex] \frac{2x}{2} = \frac{12}{2} [/tex]
[tex]x = 6[/tex]
So, the correct option is A.

Answer: The answer is C. 60
Step-by-step explanation:
you have to subtract the known angles to find the missing angles opposite angle. 180-60-70=130 then look at the line KM, it has to equal 180 so subtract the angle we just got to get the other angle 180-130=60
Solve the equation for y:
2x + 5y = 20
Answer:
y = [tex]\frac{20-2x}{5}[/tex]
Step-by-step explanation:
Given
2x + 5y = 20 ( isolate the term in y by subtracting 2x from both sides )
5y = 20 - 2x ( divide both sides by 5 )
y = [tex]\frac{20-2x}{5}[/tex]

Answer:
x=55, and y=62.5
Step-by-step explanation:
The reason why x=55 is because x and the angle 125 degrees form a linear pair (180 degrees) Hence,
x+125=180
=> x=180-125
=> x=55
Now coming to y, As we see y and 125 do not form a linear pair, so we know that x=the top angle of the triangle in which angle y is there. And with the information we also find that the triangle in which y is present is an isosceles triangle, so the other 2 angle than the top angle are equal, which are y and another angle which is also y as they are the same degrees. Hence, we know x=55, then,
55+2y=180(As the angles in a triangle sum up to 180 degrees)
=> 2y=180-55
=> 2y=125
=> y=125/2
=> y=62.5

Henry needs 2 pints of red paint and 3 pints of yellow paint to get a specific shade of orange. If he uses 9 pints of yellow paint and wants the same orange color, how many pints of paint will he need altogether? Explain how you know. 2
Answer:
Henry needs 15 pints of paint altogether
Step-by-step explanation:
If Henry uses 2 pints of red paint and 3 pints of yellow paint to get a specific color, and he now uses a total of 9 pints of yellow, then
3 x 3 = 9 (yellow)
We know that what you do on one side, you do on the other.
2 x 3 = 6 (red)
You add
9 + 6 = 15. (Red and yellow paint)
Which will lead you to the conclusion of 15 pints.
Answer:
Henry will need 15 pints altogether.
Step-by-step explanation:
Add: 6 + 9 = 15 pints
