Answer:
b = - [tex]\frac{23}{15}[/tex]
Step-by-step explanation:
- 15b - 25 = - 2
- 15b - 25 + 25 = - 2 + 25
- 15b = 23
- 15b ÷ - 15 = 23 ÷ - 15
b = - [tex]\frac{23}{15}[/tex]

What is the perimeter of a rectangle that has a length of 9 cm and a width of 6 cm?
A. 54 sq. cm
B. 54 cm
C. 30 sq. cm
D. 30 cm
Answer:
D. 30 cm
Step-by-step explanation:
A rectangle has two of the same sides and two of another length so it would be 9+9+6+6, which is 30
Answer:
d) 30 cm
Step-by-step explanation:
P = 2 (l + w)
P = 2 (9 + 6)
P = 2 (15)
P = 30
30 sq. cm woul'd be wrong because that's indicating the area (you don't use sq. when finding perimeter)

The graph below shows the distance a car can travel, y, using x gallons of gasoline.
Part A
How many miles per gallon does the car get ?
Part B
How many miles can the car travel using 9 gallons of gasoline ?
Answer:
Part A= 25 miles Part B= 225 miles
Step-by-step explanation:
The car uses 2 gallons to travel 50 miles so 1 gallon is equal to 25 miles.
Chloe has a bird feeder in her yard. When it is full of bird seed, it weighs 1234 pounds. The birds eat 112 pounds of bird seed each week. She refills the bird feeder when it weighs less than 3 pounds. Which solution represents how many weeks, w, it will take until Chloe refills the bird feeder?
Answer:
Chloe will refill the bird feeder every 11 weeks.
Step-by-step explanation:
Since Chloe has a bird feeder in her yard, which when it is full of bird seed, it weighs 1234 pounds, and the birds eat 112 pounds of bird seed each week, since she refills the bird feeder when it weighs less than 3 pounds, to determine which equation represents how many weeks, W, it will take until Chloe refills the bird feeder, the following calculation must be performed:
(1234 - 3) / 112 = W
1231/112 = W
10.99 = W
So, Chloe will refill the bird feeder every 11 weeks.

The following are the ages (years) of 5 people in a room:
25, 22, 13, 14, 21
A person enters the room.
The mean age of the 6 people is now 22.
What is the age of the person who entered the room?
I
years
Answer:
Step-by-step explanation:
First add all of the numbers together
25+22+13+14+21=82
Now add a variable like X since we don't know the age of the sixth, and divide it by 6 since there are 6 people in the class.
82+X/6=22
(22 is the mean age)
Now solve for the equation
82+X=132
so X =50

Prove that a triangle with coordinates
A(5, 6), B(8,5), and C(2, -3) is a right triangle.
Answer:
Because the side of the triangle forms pythagoras tripple
Line AB = √10
Line BC = 10
Line AC = √90
Step-by-step explanation:
From the question,
In the triangle,
Line AB = √[(8-5)²+(5-6)²]
Line AB = √(3²+-1²)
Line AB = √(9+1)
Line AB = √10
Also,
Line BC = √[(2-8)²+(-3-5)²]
Line BC = √(-6²+(-8)²)
Line BC = √(36+64)
Line BC = √100
Line BC = 10 unit.
Finally,
Line AC = √[(5-2)²+(6+3)²]
Line AC = √(3²+9²)
Line AC = √(9+81)
Line AC = √90.
From the above length of the line in the triangle,
Line AC, Line BC and Line AC are pythagoras triple.
I.e
10² = (√10)²+(√90)²
100 = 10+90
100 = 100.
Note only a a right angle triangle obeys pythagoras theorem.

Answer:
1:C
2:B
3:D
Step-by-step explanation:
To solve these questions you need to know the exterior angle theorem.
1: 8x+2+9x+6=110
17x+8=110
17x=102
x=6
2: 30+98=?
so 128
3: 9x+11+9x+5=124
18x+16=124
18x=108
x=6
A customer at a store paid $60 for 2 large candles and 6 small candles. At the same store, a second customer paid $5 more than the first customer for 1 large candle and 4 small candles. The price of each large candle is the same, and the price of each small candle is the same.
Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y?
A.
6y = 2x + 60
4y = x + 65
B.
6y = 2x + 60
4y = x + 55
C.
2x + 6y = 60
x + 4y = 65
D.
2x + 6y = 60
x + 4y = 55

solve the simultaneous equations y=3x+2 and y=x+6
Answer:
x=2
Step-by-step explanation:
y=3x+2
y=x+6
Since you're stating that, they both equal because equation is equated to equation 2 because of the Y.
Therefore, substitute into both equations as shown:
3x+2=x+6
3x-x=6-2 (bring 2 to the other side by subtracting 2 as well as x)
2x=4
2x/2=4/2 (dividing 2 on both sides to get rid off 2 in 2x)
x=2.
The solution of the given system of equations y=3x+2 and y=x+6 using the substitution method will be x = 2 and y = 8.
What is the equation?More than one variable may be present inside a linear equation.
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given system of equations,
y=3x+2 and y=x+6
Compare both values,
3x + 2 = x + 6
3x - x = 6 - 2
x = 4/2 = 2
And, y = 2 + 6 = 8
Hence "The solution of the given system of equations y=3x+2 and y=x+6 using the substitution method will be x = 2 and y = 8".

Two angles are complementary. The larger angle is 3 degrees less than twice the measure of the smaller angle. Find the measure of each angle.
Answer:
First angle would be 31°, second angle would be 59°
Step-by-step explanation:
You can use the equation 90° = a + (2a - 3°), where a is the measure of your smaller angle.
simplify:
90° = 3a - 3°
93° = 3a
31° = a
let your second angle equal (2a - 3°)
(2(31°) - 3°) = 59°
