Need help thank you very
Answer:
a)4/3
b)9/20 or 0.45
c)96
Step-by-step explanation:
a) j=3
72=20j+9p
72=20(3)+9p
72=60+9p
-9p=60-72
-9p=-12
p=-12/-9
p=4/3
b) m =1/2
20k-5=8m
20k-5=8(1/2)
20k-5=4
20k=4+5
20k=9
k=9/20 or 0.45
c) k=18
p+1/3k-20=82
p+1/3(18)-20=82
p+6-20=82
p=82+20-6
p=96

Two containers are mathematically similar. Their volumes are 54cm³ and 128cm³. The height of the smaller container is 4.5cm. Calculate the height of the larger container.
Answer:
the height of the larger container is 6 cm
Step-by-step explanation:
The computation of the height of the large container is shown below:
In the case when the factor of linear scale for two solid be k
So the factor of volume scale be k^3
Now the volume scale factor is
= 128 ÷ 54
= 64 ÷ 27
= (4 ÷ 3)^3
Now the height of the large container is
= 4.5 cm × 4 ÷ 3
= 6 cm
hence, the height of the larger container is 6 cm
In the first 8 overs the bowling rate of a cricketer is 4.5, In the last two over by giving how much run the bowling rate will be 5?
Answer:
In the last two overs, the bowler gave 14 runs.
Step-by-step explanation:
The bowling rate of 4.5 in the first 8 over means he gave 32.5 runs.
i.e.
Score given in first 8 overs = 4.5 × 8 = 36
Given that the bowling economy 5 at the end of 10 overs means the bowler must have given 10 × 5 = 50 score in the total 10 overs.
so, subtract 36 from 50 to get the score he will be giving in the last two overs.
i.e. score given the last two overs = 50 - 36 = 14
Therefore, in the last two overs, the bowler gave 14 runs.
ted's company has recieved an order to print 10^6 pages. ted's company has 100 machines , each of which can print 10^4 pages a day. ted's company can print the 10^6 pages in blank.
in exponent form, this number of days can be represented as blank
Answer:
10^0=1 day
Step-by-step explanation:
10^4 x 100=10^4 x 10²
=10^(4+2)
=10^6
Then:
10^6/10^6=10^(6-6)=10^0=1 day

Solve for x. 1/2x + 18 = 1/4x - 6
Answer:
x = -96
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
1/2x + 18 = 1/4x - 6
Step 2: Solve for x
Subtract 1/4x on both sides: 1/4x + 18 = -6Subtract 18 on both sides: 1/4x = -24Divide 1/4 on both sides: x = -9622=-2x+4(-4x-17)
solve for x pls
Answer:
x=-5
Step-by-step explanation:
22=-2x+4(-4x-17)
We move all terms to the left:
22-(-2x+4(-4x-17))=0
We calculate terms in parentheses: -(-2x+4(-4x-17)), so:
-2x+4(-4x-17)
We multiply parentheses
-2x-16x-68
We add all the numbers together, and all the variables
-18x-68
Back to the equation:
-(-18x-68)
We get rid of parentheses
18x+68+22=0
We add all the numbers together, and all the variables
18x+90=0
We move all terms containing x to the left, all other terms to the right
18x=-90
x=-90/18
x=-5
Answer:
Step-by-step explanation:
22 = -2x + 4(-4x - 17)
22 = -2x + 4*(-4x) - 4*17
22 = -2x - 16x - 68 {Combine like terms}
22 = -18x - 68 {Add 68 to both sides}
22 + 68 = -18x
90 = -18x {Divide both sides by (-18)
90/-18 = x
x = -5
What is the equation of the line shown in the graph below
A line that passes through the point -4, -3 and 2,6
Answer:
The equation is;
2y = 3x + 6
Step-by-step explanation:
We start by calculating the slope of the line
m= y2-y1/x2-x1
m = (6+3)/(2+ 4) = 9/6 = 3/2
The point slope form would be;
y-y1 = m(x-x1)
Let us use the point (-4,-3)
Thus, we have
y + 3 = 3/2(x+ 4)
2y + 6 = 3x + 12
2y = 3x + 12-6
2y = 3x + 6

The graph below shows a system of equations:
The x-coordinate of the solution to the system of equations is
Answer:
solution is (-2, 2) so x-coordinate of solution is -2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
First, we have to write down both equations.
y = x + 4
3y = -2x + 2
Now we already have an equation that we can plug into the other equation.
= 3(x + 4) = -2x + 2
= 3x + 12 = -2x + 2
= 5x + 12 = 2
= 5x = -10
x = -2
Now we know that x = -2, and the question asks for the x-coordinate, which is -2.
3x-8<-2x+22
Show it with steps please.
Answer:
x < 6
Step-by-step explanation:
1. 3x+2x = 5x
2. 5x - 8 < 22
3. 22+ 8 =30
4. 5x < 30
5. 30/5 = 6
6. x < 6
Step-by-step explanation:
3x-8<-2x+22
3x+2x< 22+8
5x<30
Divide both sides by 5
x=30

Answer:
$284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.
Step-by-step explanation:
Firstly, to calculate the portions each class should have, we should find the proportion each class takes up.
Hence, let's say A represents Mr. Aceves' class, B represents Mrs. Baca's class, and C represents Mr. Canyon's class.
The total number of box tops collected would be 3760 + 2301 + 1855 = 7916 box tops.
Therefore, the total proportions would be:
A = [tex]\frac{3760}{7916}[/tex]
B = [tex]\frac{2301}{7916}[/tex]
C = [tex]\frac{1855}{7916}[/tex]
Hence, we can finally multiply these proportions with the total prize to find the appropriate division:
Mr. Aceves' class gets [tex]\frac{3760}{7916} \cdot 600 \approx 284.99[/tex].
Mrs. Baca's class gets [tex]\frac{2301}{7916} \cdot 600 \approx 174.41[/tex].
And Mr. Canyon's class gets [tex]\frac{1855}{7916} \cdot 600 \approx 140.60[/tex].
Finally, $284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.
Hope this helped!

Jessica needs 233 feet of wood to build a fence the word comes in length of 11 feet how many pieces of wood should Jessica by Samuel needs twice as many feet as Jessica how many pieces of wood does Samuel need
Given :
Jessica needs 233 feet of wood to build a fence the word comes in length of 11 feet.[tex]N= 21\times 2[/tex]
To Find :
How many pieces of wood should Jessica by Samuel needs twice as many feet as Jessica how many pieces of wood does Samuel need.
Solution :
Total number of pieces of wood Jessica needs is :
[tex]n = \dfrac{233}{11}\\\\n = 21.18[/tex]
Since number of pieces cannot be negative.
So, n = 21
It is given that Samuel needs twice as many feet as Jessica need.
So,
N = 21 × 2 = 42
Therefore, Samuel needs 42 pieces of wood.

Step-by-step explanation:
Madelyn buys 3 bottles of orange juice at the corner store for a total cost of $2.31. If each bottle costs the same amount, how much is each bottle of juice?
Answer:
cost of each bottle of juice is $0.77
Step-by-step explanation:
Let the cost of 1 bottle be $x
multiplying both side by 3
then cost of 3 bottle will be 3*$x = $3x
given that
total cost of 3 bottles = $2.31
thus
3x = 2.31
dividing both side by 3
x = 2.31/3 = 0.77
Thus, cost of each bottle of juice is $0.77
Answer:
$0.77 for each bottle of juice
Step-by-step explanation:
Madelyn buys 3 bottles of orange juice at the corner store for a total cost of $2.31.
So,
2.31/3 = 0.77
Thus, $0.77 for each bottle of juice
