Answer:
Slope is 4/3
Step-by-step explanation:
We need to turn this into slope intercept form to find the slope,
slope intercept form is y=mx+b, we just need to "rearrange" the problem using reverse operations and get our slope
4x+3y=2
4x-4x+3y=2-4x subtract 4x from both sides ⇒ 3y=4x-2
we need to get rid of the 3, so divide both sides by 3
[tex]\frac{3y}{3} =\frac{4x-2}{3}[/tex] and we get
y=4/3x-2/3
Our slope is 4/3

At the grocery store, 6 pints of ice cream cost $8.94. How much would 35 pints of ice cream cost?
Answer:
52.15
Step-by-step explanation:
you need to find how much each pint cost by itself so...
8.94 divided by 6 is 1.49
then 1.49 x 35 = 52.15
and that is your answer
Answer:
$52.15
Step-by-step explanation:
i just dived 8.94 by 6 then multiplyed that answer by 35
½(4x - 8) = 6x + 10 solve for x and show work.
Answer:
x = -7/2
Step-by-step explanation:
½(4x - 8) = 6x + 10
simplify
2x - 4 = 6x + 10
subtract 6x from both sides
-4x - 4 = 10
add 4 to both sides
-4x = 14
divide both sides with -4
x = -14/4
simplify
x = -7/2
Answer:
½(4x - 8) = 6x + 10
4x-8=12x+20
-20-8=12x-4x
-28=8x
x=-28/8=3.5

Allison's cupcake and cookie budget for her party is $105. She would like to have at least 40 cupcakes and cookies combined, and would like to have at most 5 more
cupcakes than cookies. If cupcakes sell for $2.50 and cookies for $1.50, which system of inequalities could help Allison determine possible numbers of cupcakes (a) and
cookies (b) that she should buy? (a > 0,b> )
Answer:a+b ≥40
5+a≤ b
2.50a+1.50b≤ 105
i believe
Step-by-step explanation:
The equations would be:
a+b ≥40 (cupcakes +cookies must be at least 40 total)
5+a≤ b
(At most 5 more cupcakes then cookies)
2.50a+1.50b≤ 105
(The cost of cookies and cupcakes must be less than $105)
for a certain base, b, logb^8=3 and logb^0.5=-1 The value of logb^4b is 0, -3, 3
Answer:
3.
Step-by-step explanation:
From the question given above, the following data were obtained:
Logᵦ 8 = 3
Logᵦ 0.5 = – 1
Logᵦ 4B =?
Next, we shall determine the value of B. This can be obtained as follow:
Logᵦ 8 = 3
8 = B³
Take the cube root of both side.
B = 3√8
B = 2
Finally, we shall determine the value of Logᵦ 4B. This can be obtained as follow:
Logᵦ 4B =
B = 2
Logᵦ (4×2) = Logᵦ 8
Recall from the question given:
Logᵦ 8 = 3
Therefore,
Logᵦ 4B = Logᵦ 8 = 3
Thus, the value of Logᵦ 4B is 3.
Answer:
It ends up being 3

a train travelling at 60 km per hour completes the journey in 8 hour. How much faster would it have to travel to cover the same distance in 6 hour
Answer:
Total distance covered: 60x8 = 480
Speed needed to cover distance of 480 km in 6 hrs = 480/6 = 80 km/hr.
initial velocity : 60 km/hr.
Train needs to run faster with speed of 20km per hour to achieve same distance in 6 hrs.

Each wall measures about 65 feet tall and 80 feet wide. If Os Gemeos did a sketch on paper that was 8 inches tall for one wall, how wide would their sketch have to be to stay in proportion?
Given :
Wall measures about 65 feet tall and 80 feet wide.
To Find :
If Os Gemeos did a sketch on paper that was 8 inches tall for one wall, how wide would their sketch have to be to stay in proportion.
Solution :
Let, width of sketch is x.
Since, they are in proportion :
[tex]\dfrac{65}{10}=\dfrac{65+8}{x}\\\\x = \dfrac{10\times 73}{65}\\\\x = 11.23\ feet[/tex]
Therefore, width of sketch should be 11.23 feet.
Hence, this is the required solution.
A rectangular yard measuring 39ft by 63ft is bordered (and surrounded) by a 2 ft fence. Inside, a walk that is wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.
Given :
A rectangular yard measuring 39 ft by 63 ft is bordered (and surrounded) by a 2 ft fence.
To Find :
The area of this walk.
Solution :
Area of whole park :
[tex]A=39\times 63\ ft^2\\\\A=2457\ ft^2[/tex]
Now, length and breadth after removing the fences is l = 63 - 2( 2) = 59 ft and b = 39 - 2( 2 ) = 35 ft.
Area of inner park :
A' = 35 × 59 ft²
A' = 2065 ft²
Therefore, area of fencing is 2457 - 2065 = 392 ft² .
Hence, this is the required solution.
At school on Friday the ratio of students who purchased a lunch to students who brought lunch was 4:3. Based on the ratio, how many brought lunch out of 490 students?
Answer:
210 students brought lunch
Step-by-step explanation:
At school on Friday the ratio of students who purchased a lunch to students who brought lunch was 4:3.
The ratio is
Students who purchased: Students who brought
= 4 : 3
The total proportion
= 4 + 3 = 7
The total number of students from the question is : 490
Hence, The number of students that brought lunch is calculated as:
3/7 × 490
= 210 students
Hence, 210 students brought lunch
The Big Ben clocktower in London is approximately 316 feet tall. Shana is standing nearby and notices that she casts a 4-foot shadow. If Shana is 5 feet tall, find the length of Big Ben's shadow?
Answer:
The length of Big Ben shadow is 252.8 feet
Step-by-step explanation:
The given parameters are;
The height of the Big Ben clocktower in London ≈ 316 feet tall
The length of the shadow Shana casts = 4-foot
The height of Shania = 5 feet
Therefore, we have, by similar triangles;
[tex]\dfrac{The \ length \ of \ the \ shadow \ Shana \ casts }{The \ height \ of \ Shania} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{The \ height \ of \ the \ Big \ Ben \ clocktower}[/tex]Substituting the values, gives;
[tex]\dfrac{4 \ feet}{5 \ feet} = \dfrac{The \ length \ of \ the \ shadow \ The \ Big \ Ben \ casts}{316 \ feet}[/tex]
[tex]The \, length \, of \, the \, shadow \, The \, Big \, Ben \ clocktower \ casts = 316 \ feet \times \dfrac{4 \ feet}{5 \ feet} = 252.8 \ feet[/tex]
The length of the shadow The Big Ben clocktower casts = The length of Big Ben shadow = 252.8 feet
Answer:
252.8 feet

Answer:
Mark the lower tick marks with hour numbers; see what hour corresponds to 2/3 mile
Step-by-step explanation:
The upper number line is marked off in 1/3 mile increments.
The tick marks on the lower line divide the unit distance into 6 parts, instead of 3, so each mark on the lower line corresponds to 1/6 mile.
The problem statement tells you the completion rate is 1/6 mile per hour, so we can number the lower tick marks 0, 1, 2, 3, 4, 5, 6 hours, leaving the marks on the upper number line at 1/3 mile, 2/3 mile, and 1 mile.
Then the lower tick mark we have labeled 4 hours will correspond to the upper tick mark labeled 2/3 mile.

To solve the problem using number lines, mark the number lines with values that correspond. Extend the numbering as required to answer the question asked.

John keeps chickens and rabbits in his fenced backyard. He counts a total of 32 heads and a total of 72 legs in his backyard. Write and solve a system of equations in order to find: How many chickens are in John's backyard? Chickens How many rabbits are in John's backyard? Rabbits
Answer:
System of Equations
c + r = 32 ..... Equation 1
2c + 4r = 72......... Equation 2
We have 28 chickens and 4 rabbits
Step-by-step explanation:
Let the number of chickens be represented by c
The number of rabbits be represented by r
From the question, John counts:a total of 32 heads
32 heads = a total of 32 animals
Hence:
c + r = 32....... Equation 1
c = 32 - r
Also, John counts:
A total of 72 legs in his backyard.
Chickens have: 2 legs
Rabbits have: 4 legs
Hence:
2c + 4r = 72......... Equation 2
System of Equations is:
c + r = 32 ..... Equation 1
2c + 4r = 72......... Equation 2
Lets us substitute 32 - r for c in Equation 2
2(32 - r) + 4r = 72
64 - 2r + 4r = 72
Collect like terms
- 2r + 4r = 72 - 64
2r = 8
r = 8/2
r = 4
This means we have 4 rabbits
Note:
c = 32 - r
r = 4
c = 32 - 4
c = 28
Hence, we have 28 chickens
