Answer:
3 2/5
Step-by-step explanation:
Assuming that you meant 17/5, because 5/17 can't be made into a mixed fraction: The closest multiple of 5 is 15. There is 2 left over. So, that makes 3 2/5.

Step-by-step explanation:
Given
-30 = - 0.4 k
30 = 0.4k
k = 30 / 0.4
k = 75
hope it helps :)
Answer:
Simplifying
-38 = -0.4k
Solving
-38 = -0.4k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '0.4k' to each side of the equation.
-38 + 0.4k = -0.4k + 0.4k
Combine like terms: -0.4k + 0.4k = 0.0
-38 + 0.4k = 0.0
Add '38' to each side of the equation.
-38 + 38 + 0.4k = 0.0 + 38
Combine like terms: -38 + 38 = 0
0 + 0.4k = 0.0 + 38
0.4k = 0.0 + 38
Combine like terms: 0.0 + 38 = 38
0.4k = 38
Divide each side by '0.4'.
k = 95
Simplifying
k = 95

How do you create and solve equations in one variable given a real–world situation?
Step-by-step explanation:
1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)
ex: if x+9=32
subtract 9 from both sides to get rid of it
x=23
2) if there is another constant but this constant is being multiplied/divided then do the opposite operation to remove it
you could multiply by 3 on both sides:
x+9=69
x=60

5.(x+3) = 2x-3 Help pls
Answer:
x= -6
Step-by-step explanation:
5.(x+3) = 2x-3
5x+15=2x-3
5x-2x+15=-3
5x-2x=-3-15
3x=-3-15
3x=-18
x=-6
Step-by-step explanation:
5(X+3) =2X_3
Expand the brackets
5X + 15 = 2X _ 3
CLT(Collect like terms)
5X_2X= _3 _ 15
3X = _ 18
DBS( Divide both sides) by 3
3X/ 3 = _18 / 3
X = _9

A line goes through the point (-8,9), and has a slope of 3/4
Write in form of a Ax + B and C for this line
Answer:
[tex]y=\dfrac{3}{4}x+15[/tex]
Step-by-step explanation:
Given that,
A line goes through the point (-8,9), and has a slope of 3/4.
We need to express in the form of Ax+B for this line.
We have, m = 3/4
So,
[tex]y=\dfrac{3}{4}x+B[/tex]
Put y = 9 and x = -8 in the above equation.
[tex]9=\dfrac{3}{4}(-8)+B\\\\9=-6+B\\\\9+6=B\\\\B=15[/tex]
So,
[tex]y=\dfrac{3}{4}x+15[/tex]
It is the required equation of the line.

Answer:
2t+5
Step-by-step explanation:
Please help ASAP math
Answer:
(1,-4)
Step-by-step explanation:
First manipulate the second equation so that y is by itself
x-y=5
-y=-x+5
y=x-5
then substitute that y in for the y in the above equation and solve for y
y=-2x-2
x-5=-2x-2
3x-5=-2
3x=3
x=1
Now that you have the x-coordinate, find the y-coordinate by plugging in the x-value in either of the equations
y=-2x-2
y=-2(1)-2
y=-2-2
y=-4
I see that you're using deltamath, and I think for the graph questions, you could first place a point for the y-intercept of one of the equations, and then place another point that is on the graph of the equation. Once you plotted both lines, just see the point where they meet and that is where the two systems of equations meet.

Find the perimeter of the triangle with vertices D(5, 6), E (10, 9), and F(7, 11). Do not
round before calculating the perimeter. After calculating the perimeter, round your
answer to the nearest tenth.
The perimeter is
units.
Answer:
Perimeter of triangle = 14.82 approx.
Step-by-step explanation:
Given:
D(5, 6)
E (10, 9)
F(7, 11)
Find:
Perimeter of triangle
Computation:
Distance = √(x1-x2)² + (y1-y2)²
Perimeter of triangle = DE + EF + FD
Perimeter of triangle = √(5-10)² + (6-9)² + √(10-7)² + (9-11)² + √(7-5)² + (11-6)²
Perimeter of triangle = √25 + 9 + √9 + 4 + √4 + 25
Perimeter of triangle = √34 + √13 + √29
Perimeter of triangle = 5.83 + 3.6 + 5.3851
Perimeter of triangle = 14.8151
Perimeter of triangle = 14.82 approx.

What is 7 and three tenths minus 5 and seven tenths
Answer:
1.6
Step-by-step explanation:
7 and three tenths = 7 + 3/10 = 7.3
5 and seven tenths = 5 + 7/10 = 5.7
7.3-5.7 = 1.6 or can be written as 1 and six tenths, or 1 and three fifths.
How do you solve 2.5x + 10 = 50?
Answer:
I think the answered is x = 16 hope I right
Answer:
X = 16
Step-by-step explanation:
2.5x+10 = 50
distribute the ten to the other side by substracting
2.5x = 50-10
2.5x = 40
Now divide 2.5 on both sides
2.5x/2.5 = 40/2.5
x = 16

X + 14 = 56 What would I do to both sides to answer this equation? O Multiply both sides by 14 © Subtract both sides by 14 Subtract both sides by 14 Add both sides by 14
To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that
X + 14 - 14 = 56 - 14
X=42
Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.

In the first equation, sub in (-3x/2) for y:
3x+4y=12
3x+4(-3x/2)=12
3x-(12x/2)=12
3x-6x=12
-3x=12
x=-4
y=-3x/2
y=-3(-4)/2
y=12/2
y=6
Since x=-4 and y=6, (-4,6) is a solution.
