what is -5x + 3y= 12 in slope intercept form?
Answer:
y = (5/3)x + 4
Step-by-step explanation:
-5x + 3y = 12 (What you start with)
3y = 12 + 5x (Adding 5x to both sides)
y = (5/3)x + 4 (Dividing the equation by 3)
Determine the value of x and y

Painter has 7/8 liters of paint remaining each statue requires 1/20 how many statues can she paint
Answer:
1/20 liters per statue
so you divide 7/8 by 1/20
7/8*20/1
17.5 statues
but there cant be decimal statues,
so 17 statues is the answer
Answer:
17 statues.
Step-by-step explanation:
7/8 / 1/20
= 7/8 * 20
= 140/8

The figure is made up of a square and a rectangle. Find the area of the shaded region.
first we do
square is length 6 so base =6
10-6=4
the rectangle is 2 by 4
base=4
square is 6 by 6
rectangle is 4 by 2
split the triangles up
area of triangle=1/2base times height
rectangle triangle base=4
height=2, area=1/2 times 2 times 4=4
square triangle
flip 90 degrees clockwise so we have base=2
height=6
area=1/2 times 2 times 6=6
add
4+6=10
total area=10m^2
if p is directly proportional to 7 and p=12 when t =4 find the value of t when p=18
Answer:
When p=18, t=6
Step-by-step explanation:
If p and t are directly proportional, then:
p = k.t
Where k is the constant of proportionality.
We are given an initial condition: when p=12, then t=4. Substituting in the equation:
12 = k.4
Solving for k
k = 12/4 =3
The equation is:
p = 3t
Now we are required to find the value of t when p=18:
18 = 3t
Solving for t:
t = 18/3 = 6
t = 6
Thus, when p=18, t=6

Step 2: Solve for y
Add 6 to both sides: 3(2y - 3) = -6Divide 3 on both sides: 2y - 3 = -2Add 3 to both sides: 2y = 1Divide 2 on both sides: y = 1/2Answer:
Step-by-step explanation:

step 1
3(2y-3)-6=-12 equation
step 2
3(2y-3)-6=-12 simplify
(3)(2y)+(3)(-3)+-6=-12
step 3
(3)(2y)+(3)(-3)+-6=-12 distribute
6y+(-9)+(-6)=-12
step 4
(6y)+(-9+-6)=-12 combine the terms
6y-15=-12
step 5
6y-15(+15)=-12(+15) add +15 to both sides
6y=3
step 6
6y/6=3/6

Eber ran 3 miles. He stopped to take a break every {3}{4) mile.How many times did Eber stop, including his final stop at the end of the run?
Answer:
4 times
Step-by-step explanation:
The total model is 3 miles, divided by 3/4 equals the multiplication problem 3/1 times 3/4 but use the reciprocal of 3/4 which is 4/3 so it would be 3/1 times 4/3 which is 12/3 which is equivalent to 4. :)
There are 4 times did Eber stop.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Eber ran 3 miles.
And, He stopped to take a break every 3/4 mile.
Now,
Let number of times stop = x
So, We can formulate;
⇒ 3/4x = 3
⇒ x = 3 × 4 / 3
⇒ x = 12/3
⇒ x = 4
Thus, There are 4 times did Eber stop.

In a particular triathlon the athletes cover 1/24 of the total distance by
swimming, 1/3 of it by running, and the rest by bike. What is the ratio of
the distance covered by bike to the distance covered by running?
Answer:
15/8
Step-by-step explanation:
Let "d" be the total distance, that is, the distance for swimming (s), running (r) and going by bike (b).
d = s + r + b [1]
1/24 of the total distance is covered by swimming.
s = 1/24 d [2]
1/3 of the distance is covered by running.
r = 1/3 d [3]
If we replace [2] and [3] in [1], we get
d = 1/24 d + 1/3 d + b
b = d - 1/24 d - 1/3 d
b = 24/24 d - 1/24 d - 8/24 d
b = 15/24 d = 5/8 d
The ratio of the distance covered by bike to the distance covered by running is:
b/r = (5/8 d)/(1/3 d) = 15/8
Select all ordered pairs that satisfy the function y=4x+3.
I suppose that you should have given some pairs to choose from.
Anyway, I can tell you how to do it. Given a pair [tex](a,b)[/tex], you have to substitute [tex]a[/tex] and [tex]b[/tex] to [tex]x[/tex] and [tex]y[/tex] respectively, and see if you get something true.
For example, the pair [tex](1,7)[/tex] satisfies the function, because the substitution yields
[tex]7=4\cdot 1+3[/tex]
which is true. On the other hand, the pair [tex](19,3)[/tex] doesn't satisfy the function, because
[tex]3=4\cdot 19+3[/tex]
is clearly false.

In a study, subjects are randomly assigned to one of three groups: control, experimental A, or experimental B. After treatment, the mean scores for the three groups are compared. The appropriate statistical test for comparing these means is:
Answer:
Analysis of variance
Step-by-step explanation:
The appropriate statistical tool for this is the analysis of variance. The analysis of variance, also known as the ANOVA, is a statistical method which has the ability to separate data from observed variance into various components which is then use for more tests.
The anova gives an analysis of the differences that are in the group means of a sample.
The appropriate statistical test for comparing these means is Analysis of variance.
ANOVA stand for Analysis of variance. It is a statistical models and its associated estimation procedures are used to analyze the differences among means.
It simply provides a statistical test for two or more population to check if the means are equal or not, and therefore generalizes the t-test beyond two means.
Hence, the appropriate statistical test for comparing these means is Analysis of variance.

Theo borrows $8,000 for college expenses. He will pay a total of $10,280 after 6 years. What percent of interest did Theo pay?
i will give you 10 coins
9514 1404 393
Answer:
4.75%
Step-by-step explanation:
When simple interest is charged, the payback amount is ...
A = P(1 +rt) . . . . for annual rate r and a term of t years
Using the given values, we can solve for r.
10280 = 8000(1 +6r)
1.285 = 1 +6r . . . . . . . . divide by 8000
0.285 = 6r . . . . . . . . . . subtract 1
0.285/6 = r = 0.0475 = 4.75% . . . . . . divide by 6; express as %

Marshall has $0.34 in dimes and pennies. He has 7 coins altogether. How many coins of each kind does he have?
Dimes are 0.10 each
Pennies are 0.01 each

Then you would have 3 dimes .
3 x 0.10 = 0.30
4 x 0.01 = 0.04
0.30 + 0.04 = 0.34
