Step-by-step explanation:
3y - 2x = 7
Subtract 3y from both sides;
-2x = -3y + 7
Divide both sides by -2
[tex]x=\frac{3}{2}y-\frac{7}{2}[/tex]
Solve the equation.
–9x + 1 = –x + 17
x = –8
x = –2
x = 2
x = 8
-9x + 1= -x + 17
- 9x + x= 17 - 1
-8x = 16
- x = 16÷8
x = -2
Answer:
-9x + 1= -x + 17
- 9x + x= 17 - 1
-8x = 16
- x = 16÷8
x = -2

An unused roll of paper towels is shown. What is the volume of the unused role
Answer:
1310.4
Step-by-step explanation:
26 x 12= 312 x 4.2= 1310.4
The volume of the unused role is 821.34π cm³
What is the volume?Volume is defined as the space occupied within the boundaries of any three-dimensional solid.
Given that is a figure of unused roll of paper towels, we need to find the volume of the unused role,
The volume of a cylinder with radius r and height h is V = π·radius²·height
To find the same we will subtract the volume of the inner cylinder from the outer,
Volume = 6²π(26) - (2.1)²π(26)
= 26(36π - 4.41π)
= 26(31.59π)
= 821.34π cm³
Hence, the volume of the unused role is 821.34π cm³

1. What will happen to the current if the voltage is decreased by one half while the
resistance is held constant? State the relationship of voltage and current based
on your answer.
Answer: Current will reduce by half
Step-by-step explanation:
The formula for Current is;
Current = Voltage/ Resistance
Say for instance that Voltage is 5 volts and Resistance is 2 ohms. Current will be;
= 5/2
= 2.5 amps
If Voltage is decreased by one half to 2.5 while resistance is held constant, current becomes;
= 2.5/2
= 1.25 amps
Current went from 2.5 to 1.25 amps.
This shows that current will reduce by half if the voltage is decreased by one half while the resistance is held constant.

Writing proportional equations Problem The Green Goober, a wildly unpopular superhero, mixes 333 liters of yellow paint with 555 liters of blue paint to make 888 liters of special green paint for his costume. Write an equation that relates yyy, the amount of yellow paint in liters, and bbb, the amount of blue paint in liters, needed to make the Green Goober's special green paint.
Answer:
The equation that relates the amount of yellow paint, y, and the amount of blue paint,b, in liters [tex]5y-3b=0[/tex].
Step-by-step explanation:
Given that The Green Goober mixes 333 liters of yellow paint with 555 liters of blue paint to make 888 liters of special green paint for his costume.
So,
The amount of yellow paint: the amount of blue paint [tex]= 333: 555[/tex]
If the amount of yellow paint is y and the amount of blue paint is b, then, from the above relation
[tex]y: b = 333: 555\Rightarrow \frac y b = \frac {333}{555} \\\\\Rightarrow \frac y b = \frac {3}{5} \\\\\Rightarrow 5y=3b \\\\\Rightarrow 5y-3b=0.[/tex]
Hence, the equation that relates the amount of yellow paint, y, and the amount of blue paint,b, in liters [tex]5y-3b=0[/tex].
Answer:
5y-3b=0

The radius of a semi-circle measures 5
units. Find its area.
Answer:
≈39.27 units
Step-by-step explanation:
To find the area of a semi circle, you use the formula for finding the area of a circle, which is [tex]\pi[/tex][tex]r^{2}[/tex], and then you divide that by 2 since it is half of a circle.
In this case, [tex]\pi[/tex][tex](5)^{2}[/tex] ≈ 78.54
[tex]\frac{78.54}{2}[/tex] = 39.27

If a ship travels north for 18 miles and east for 12 miles,
to the nearest tenth, approximately how far away is it
from it's starting point?
Answer:
The ship is approximately 21.6 miles away from its starting point
Step-by-step explanation:
∵ The North and the East are perpendicular
→ That means the distance between the starting position and
the ending position shows a hypotenuse of a right triangle which
its legs are the distances due to North and East
∵ The ship travels north for 18 miles
∴ leg1 = 18 miles
∵ The ship travels east for 12 miles
∴ leg2 = 12 miles
→ By using Pythagoras Theorem
∵ (hypotenuse)² = (leg1)² + (leg2)²
∴ (hypotenuse)² = (18)² + (12)²
∴ (hypotenuse)² = 324 + 144
∴ (hypotenuse)² = 468
→ Take √ for both sides
∴ hypotenuse = 21.63330765
→ Approximate it to the nearest tenth
∴ hypotenuse = 21.6 miles
∵ The hypotenuse of the right triangle represents the distance from
the starting position to the ending position
∴ The ship is approximately 21.6 miles away from its starting point

Solve the simultaneous equations:
3a-2b=14
4a+3b=13
Answer:
Step-by-step explanation:
3a-2b=14 multiply by 3
9a - 6b = 42 (1)
4a+3b=13 multiply by 2
8a +6b = 26 (2)
sum up (1) and (2)
17a = 68
a =4
b=-1
Answer:
a = 4 b = -1
Step-by-step explanation:
13 = 4a - 3b (1)
14 = 3a + 2b (2)
(1) x 2
(2) x 3
26 = 8a - 6b (3)
42 = 9a + 6b (4)
(3) + (4)
68 = 17a
68/17 = 17a/17
a = 4
Substitute back in to original equation
14 = 3(4) - 2b
14 = 12 - 2b
14 - 12 = 12 -12 - 2b
2 = -2b
Divide by -2 both sides
b = -1
Check
3(4) - 2(-1)
12 + 2 = 14

In how many ways can 3

There are 2300 ways by which we can select 3 students out of 25 students.
What is Combination?Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements.
Here total number of Students = 25
Number of selection = 3
Now,
Total number of ways by which we can select 3 out of 25 = ²⁵C₃
= 25!/3!.22!
= 25 X 24 X 23 X 22! / 3X2X1 X 22!
= 13800 / 6
= 2300
Thus, there are 2300 ways by which we can select 3 students out of 25 students.
