Answer:
5,6,7
Step-by-step explanation:
consetive integers are 1 apart
they are
x,x+1,x+2
3 times the first added to the last is 22
3x+x+2=22
combine like terms
4x+2=22
minus 2 both sides
4x=20
divide both sides by 4
x=5

in this in this equation y equals 14 x what is the constant of proportionality
Answer:
We conclude that the value of the constant of proportionality.
k = 14Step-by-step explanation:
We know that if 'y' varies directly with 'x', we use the equation
y ∝ x
y = kx
where 'k' is called the constant of proportionality.
Given the equation
y = 14x
comparing with the equation
y = kx
Thus,
k = 14
Therefore, we conclude that the value of the constant of proportionality.
k = 14PLEASEEEEE HELPPPP!
Answer:
option 4
Step-by-step explanation:
put like terms on either side
9x + 2a = 3a - 4x
subtract both sides by 2a
9x = a - 4x
add both sides by 4x
13x = a
divide both sides by 13
x = a/13
please give thanks, hit that heart button :)
Answer:
4.) a/13
Step-by-step explanation:
9x + 2a = 3a - 4x
9x + 4x = 3a - 2a
13x = a
13x/13 = a/13
x = a/13

what is the solution (x,y) to the system of equations? x=10 3x+5y=20
Answer:
(10, -2)
Step-by-step explanation:
x = 10 (its given in the problem)
then plug in 10 for x in the second equation and solve for y
3(10) + 5y = 20
30 + 5y = 20
5y = -10
y = -2
so the solution is (10, -2)
a satellite makes 4 revolutions of the earth in one day. How many revolutions would it make in 6 ½ days
Answer:
26.
Step-by-step explanation:
1 day/24 hours, makes 4 revolutions.
4 x 6 = 24,
1/2 of 4 = 2.
24+2 = 26.
26 revolutions, if my answer is wrong someone please correct me.
make 24 using 15,15,9,6
Answer:
24 = (9 * 6) - (15 + 15)
Step-by-step explanation:
Equation = (9 * 6) - (15 + 15)
Follow PEMDAS which in this case multiply 9 x 6
= 54 - (15+15)
Now you need to add the numbers that are in the parenthesis
= 54 - 30
= 24

67, degrees.
What is the measure of \angle b∠bangle, b?
Answer:
Assuming the question is asking for angle B, it measures 23°
Step-by-step explanation:
If angle A = 67°, and angle A and angle B are complementary, then you know they add up to 90°.
angle A + angle B = 90°
67° + Angle B = 90°
Angle B = 23°

Answer:
the slope is 5/4
Step-by-step explanation:
use the formula y2 - y1 over x2 - x1, and plug in the coordinates into that
The slope of the line whose points are (1, 4) and (5, 9) will be 1.25.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is given as,
m = (y₂ - y₁) / (x₂ - x₁)
The points are given below.
(1, 4) and (5, 9)
The slope of the line is given as,
m = (9 - 4) / (5 - 1)
m = 5/4
m = 1.25
The slope of the line whose points are (1, 4) and (5, 9) will be 1.25.

SYSTEM:
log base root3 of (x-y) = 2
log base 4 of x - log base x of y = 7/6
Answer:
Step-by-step explanation:
SYSTEM:
log base root3 of (x-y) = 2 .... 1
log base 4 of x - log base x of y =7/6...2
From equation 1:
x-y = (√3)²
x - y = 3 ..... 3
From equation 2:
log base 4 of x - log base x of y =7/6
-log base x of 4 - log base x of y = 7/6
log base x of 4^-1 - log base x of y = 7/6
log base x of (1/4) - log base x of y = 7/6
According to law of logarithm
Log base x {1/4 ÷ y} = 7/6
x^7/6 = 1/4y .... 2
From 1, y = x-3
x^7/6 =1/4(x-3)
x^7/6 = 1/(4x-12)
x^7/6(4x-12) = 1

The total price of five DVDs (all the same cost) and four movie tickets (all the same cost) is $138, whereas, the total price of two DVDs and five movie tickets is $96. What is the price of one movie ticket? Answer as a number with NO units and NO decimals. Only give the answer to the question asked.
Answer:
Step-by-step explanation:
Let the price of DVDS = x
The price of movie tickets = y
The total price of five DVDs (all the same cost) and four movie tickets (all the same cost) is $138,
= 5x + 4y = $138
The total price of two DVDs and five movie tickets is $96.
2x + 5y = $96
Hence:
5x + 4y = $138.... Equation 1
2x + 5y = $96..... Equation 2
What is the price of one movie ticket?

Given that:
Number of mobile phones = 450
Cost per mobile phone = $30
Number of mobile phones purchased = 3
The total cost of 3 mobile phones = amount paid remaining :
(Cost per mobile phone * number of mobile phones purchased)
= $30 * 3
= $90
