Percy wants to buy a guitar that costs $56. He plans to save the same amount of money each week for 7 weeks. How much money should Percy save each week so that after 7 weeks he will have exactly enough for the guitar? $5 $8 $48 $64
Answer:
$8
Step-by-step explanation:
Let x represent the amount of money he has to save each week.
We can use this to set up an equation:
[tex]7x=56[/tex]
Now, we have to "isolate the variable". This means we must have a resulting equation of [tex]x=\text{something}[/tex].
In this case, we can use the Division Property of Equality to divide both sides by 7:
[tex]\frac{7x}{7}=\frac{56}{7}\\x=8[/tex]
Therefore he must say $8 each week for 7 weeks so that he can buy the guitar.

Answer:
x = y - 6
Step-by-step explanation:
Use PEMDAS to move x to the other side.
y=x+6
Subtract 6 from both sides to get rid of 6 on one side to make x the subject.
y-6=x

[tex]\mathbb{SOLUTION\;WITH\;STEPS:}[/tex]
Hi! Hope you are having a nice day!
In order to make x the subject, we need to solve for x.
It's easy, right?
We have
y=x+6
Move x to the left. Be sure to use the opposite operation.
y-x=6
Now, move y to the right:
-x=6-y
x=-6+y
or
x=y-6
There's an easier way:
y=x+6
y-6=x
x=y-6 (See? We ended up with the same answer :) )
Hope you could understand everything.

2x + 4x = 180
6x = 180
x = 30
2x = 2(30) = 60
4x = 4(30) = 120

8x + 10x = 180
18x = 180
x = 10
8x = 8(10) = 80
10x = 10(10) = 100
4.
7x + 8x = 180

The value of the variable x will be 60°. Then the measure of the angles ∠GFH and ∠CBD will be 60° and 120°.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The angles ∠GFH = x and ∠CBD = 2x.
From the figure, the angles ∠GFH and ∠CBD are supplementary angles.
∠GFH + ∠CBD = 180°
x + 2x = 180°
3x = 180°
x = 60°
Then the measure of the angles ∠GFH and ∠CBD will be
∠GFH = 60°
∠CBD = 2 × 60°
∠CBD = 120°
The value of the variable x will be 60°. Then the measure of the angles ∠GFH and ∠CBD will be 60° and 120°.

NEED HELP ASAP! Which of the following could be the second equation in the system of equations seen below, so that the system has infinite solutions? Select all that apply.
Answer:
B, E, F
Step-by-step explanation:
If the system has infinite solutions, then the 2 equations will be identical.
So we are looking for an equation, which, when simplified or rearranged or multiplied by a constant, will be the same as the given equation [tex]4x-6y=12[/tex]
If we multiply equation A by 2 we get: 4x + 6y = 12
This is not the same as the original equation since the operation sign is addition rather than subtraction.
If we divide equation B by 5 we get: 4x - 6y = 12
This is identical to the original equation, and therefore could be the second equation.
Equation C: y = (2/3)x + 12
Multiply by 3: 3y = 2x + 36
Multiply by 2: 6y = 4x + 72
Rearrange: 4x - 6y = -72
If we divide equation D by 1.5 we get: 4x - (8/3)y = 8
Equation E: y = (2/3)x - 2
Multiply by 3: 3y = 2x - 6
Multiply by 2: 6y = 4x - 12
Rearrange: 4x - 6y = 12
This is identical to the original equation, and therefore could be the second equation.
Equation F: 3y = 2x - 6
Multiply by 2: 6y = 4x - 12
Rearrange: 4x - 6y = 12
This is identical to the original equation, and therefore could be the second equation.
Suppose a triangle has a side lengths AB, BC, and x where AB=2 • BC. Find the possible range for x in the terms of BC.
The possible range for x, in the terms, of BC is BC < x< 3BC.
Triangle Inequality TheoremIn mathematic, there is a rule for triangle side lengths. This rule says that the sum of the lengths of any two sides of a triangle is greater than the length of the one side (third side). Therefore,
[tex]L1+L2 > L3\; (1)\\ \\ L1+L3 > L2\; (2)\\ \\ L2+L3 > L1\; (3)[/tex]
The question gives three sides: AB (L1), BC (L2) and x (L3). Also, you know that AB=2 BC.
Applying the equation (1) of rule for triangle side lengths, you have:
L1+L2> L3
AB+BC > x
2BC+BC > x
3BC > x
x< 3BC
Applying the equation (2) of rule for triangle side lengths, you have:
L1+L3 > L2
AB+x >BC
2BC+x > BC
x > -BC
Applying the equation (3) of rule for triangle side lengths, you have:
L2+L3 > L1
BC + x > AB
BC + x > 2BC
x > BC
The intersection of the inequalities results is the solution of this problem. Then, the possible range for x, in the terms, of BC is BC < x< 3BC. See the attached image.

17, 18, 19Help! How do I do this?
Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
and the sum of all angles around one point at one side of a line is also airways 180° (because you can imagine that point to be the center of a circle, and the line would cut that circle in half = 180° for every half).
in the triangle LKM we know 2 angles already :
angle 1 = 44°
angle K = 90° (right angle).
so, angle 2 = 180 - 90 - 44 = 46°
and so, angle 5 = 180 - 46 = 134°.
as the angles around point L on line KL are the angles 2 and 5.
angle 5 = 134°
