Answer: The hook would be 2.2 inches (approximately) above the top of the frame
Step-by-step explanation: Please refer to the picture attached for further details.
The top of the picture frame has been given as 9 inches and a 10 inch ribbon has been attached in order to hang it on a wall. The ribbon at the point of being hung up would be divided into 5 inches on either side (as shown in the picture). The line from the tip/hook down to the frame would divide the length of the frame into two equal lengths, that is 4.5 inches on either side of the hook. This would effectively give us two similar right angled triangles with sides 5 inches, 4.5 inches and a third side yet unknown. That third side is the distance from the hook to the top of the frame. The distance is calculated by using the Pythagoras theorem which states as follows;
AC^2 = AB^2 + BC^2
Where AC is the hypotenuse (longest side) and AB and BC are the other two sides
5^2 = 4.5^2 + BC^2
25 = 20.25 + BC^2
Subtract 20.25 from both sides of the equation
4.75 = BC^2
Add the square root sign to both sides of the equation
2.1794 = BC
Rounded up to the nearest tenth, the distance from the hook to the top of the frame will be 2.2 inches
Answer:
A.) After adding 4 to both sides, the equation is
C.) The equation can be solved for x using exactly one more step by multiplying both sides by
D.) The equation can be solved for x using exactly one more step by dividing both sides by
Step-by-step explanation:
The correct questions is as follows:
Carina begins to solve the equation -4-2/3x=-6 by adding 4 to both sides. Which statements regarding the rest of the solving process could be true? Check all that apply.
A.) After adding 4 to both sides, the equation is -2/3x=-2.
B.) After adding 4 to both sides, the equation is -2/3x=-10 .
C.) The equation can be solved for x using exactly one more step by multiplying both sides by -3/2.
D.) The equation can be solved for x using exactly one more step by dividing both sides by -2/3.
E.) The equation can be solved for x using exactly one more step by multiplying both sides by -2/3.
Given equation:
To show the steps we will carry out in order to solve for
Solution:
Solving for
Step 1:
Adding both sides by 4
Thus, we get:
Thus statement A is correct.
Step 2:
Multiplying both sides by
Thus, we get:
[Two negatives multiply to give a positive]
This proves that statement C is correct.
Or Step 2:
Dividing both sides by
Thus, we get:
[On dividing with a fractional divisor, we take reciprocal and multiply it with the dividend.]
[Two negatives multiply to give a positive]
This prove that statement D is correct.
