5p = 20
5 5
p = 4
(p, c) = (4, 7)
Answer:
c= 7 p=4
Step-by-step explanation:
3p + 4c = $40
therefore
15p + 20c = 200
5p + 2c = 34
therefore
15p + 6c = 102
14c = 98
98/14=7
c = 7
5p + 2(7) = 34
5p + 14 = 34

A garden patio is covered wit grey slabs and yellow slabs .1/5 of the slabs are grey a)write down the ratio of grey slabs to yellow slabs give your answer in its simplest form b)there are 55 slabs in total work out the number of yellow slabs
Answers
Answer:
1:u
Step-by-step explanation:
Grey slabs = 1/5 of total slab
Say total slab = x
Then,
Grey slabs = 1x/5
We can represent
Yellow slabs = u/5
Then ratio of Grey to yellow would be;
Gray slabs / Yellow slabs = (1x/5)/(u/5)
=1/u
= 1:u
Since there are 55 slabs in total, then
Yellow slab would be = 55/5 = 11

A line passes through the point (8,-9) and has a slope of -5/4.
Write an equation in point-slope form.
Answers
Answer:
y=-5/4x-19
Step-by-step explanation:
y=-5/4(x(-8))-9
y=-5/4x-10-9
y=-5/4x-19
M = -5/4
2. Y- intercept
Y = mx + b
-9 = (-5/4)(8) + b
-9 = -10 + b
-9 + 10 = -10 + 10 + b (the ten cancels out and we are just left with our b)
1 = b
So, therefore, the equation is:
Y = -5/4x + 1

Your Olympic team wins 48 medals in the spring. The medals are gold, silver, and bronze in a ratio of 2 : 1 : 5. How many of each medal did your team win?
Answers
Answer:
12, 6 and 30
Step-by-step explanation:
Step one:
given data
Number of medals = 48 medals
The given ratio is = 2:1:5
The total ratio is = 2+1+5= 8
Step two;
Applying the part to all method
for Gold we have
2/8=x//48
cross multiply
8x= 48*2
divide both sides by 8
x= 96/8
x= 12
gold is 12
for silver we have
1/8=x//48
cross multiply
8x= 48*1
divide both sides by 8
x= 48/8
x= 6
silver is 6
for bronze we have
5/8=x/48
cross multiply
8x= 48*5
divide both sides by 8
x= 240/8
x= 30
Bronze is 30

write the equation of the graphed in NO SPACES ALL LOWERCASE
Help !!
Answers
Answer:
The equation of the graphed line is:
y = 2Step-by-step explanation:
From the graph, it is clear that the line is a horizontal line at y = 2.
We know that a horizontal line has a slope of 0 because the value of y does not change no matter what the value of x we put in.
In other words, the equation of the horizontal line would always get the form:
y = k
where k is the y-intercept of the line.
Determining the y-intercept of the line:
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 2
Thus, the y-intercept k = 2
Thus, if we substitute the y-intercept k = 2 in the equation y = k, we get the equation
y = 2
Therefore, the equation of the graphed line is:
y = 2Last four steps that could perform to solve the equation 4(3x-20)-x=16-x
Place the steps in correct order
Add x to both sides, add 20 to both sides, divide both sides by 3, add 16 to both sides, divide both sides by 4, divide both sides by 12, distribute 4 to get 12x-20

Answer:
add x to both sidesdivide both sides by 4add 20 to both sidesdivide both sides by 3Step-by-step explanation:
Your steps in order would be ...
add x to both sidesdivide both sides by 4add 20 to both sidesdivide both sides by 3__
Executing these steps, we get ...
4(3x -20) = 16 . . . . . add x
3x -20 = 4 . . . . . . . . divide by 4
3x = 24 . . . . . . . . . . .add 20
x = 8 . . . . . . . . . . . . . divide by 3, giving the solution

Additional comment
If you were to distribute the 4 first, you would have ...
12x -80 -x = 16 -x
Now, you can add x and add 80 to get ...
12x -80 = 16
12x = 96
Then dividing by 12 gives ...
x = 8

The most important outcome of the Adams-Onis Treaty of 1821 was that Florida became a territory of the United States. Spain no longer had a US presence. Spain gave up rights to Alabama and Georgia. Florida became the twenty-seventh state to enter the Union.
Answers
Answer:
Florida became a territory of the United States.
Step-by-step explanation:
i got it right on Edge
The correct option for the given statement is Florida became a territory of the United States.
Adams-Onís TREATY:-
The Adams-Onís Treaty between the United States and Spain was negotiated by Secretary of State John Quincy Adams and the Spanish Minister to the United States, Don Luis de Onís, and signed in February 1819.
The principal elements in the treaty were the acquisition of Florida by the United States and the establishment of a boundary line between Spanish territory and the United States.
After the Louisiana Purchase in 1803, Pres. Thomas Jefferson argued that Florida was included in Louisiana. In 1810 and 1812 the United States annexed sections of West Florida.
In the treaty Spain gave East and West Florida to the United States, and the United States agreed to assume claims by citizens of the United States against Spain.
Hence, the answer is Florida became a territory of the United States.
