Which statement correctly explains how Marì could find the solution to the following system of linear equations using
elimination?
2f-5g=-9
-7+3g=4
Given that,
The equations : 2f-5g=-9 and -7f+3g=4
To find,
The solution of the above equations.
Solution,
We have,
2f-5g=-9 ....(1)
-7f+3g=4 ......(2)
Multiply equation (1) by 7 and equation (2) by 2.
14f-35g=-63 ....(3)
-14f+6g=8 ......(4)
Add equation (3) and (4)
14f-35g -14f+6g = -63 + 8
-29g = -55
g = 55/29
g = 1.89
Put the value of g in equation (1).
2f-5(1.89)=-9
2f = -9+5(1.89)
f = 0.225
Hence, the solution of the above equations are g = 1.89 and f = 0.225.

A 36 inch post cast a shadow of 24 inches. At the same time a telephone pole cast a shadow of 22 ft 8 in. What is the height in feet of the telephone pole?
Answer:
The height of the telephone pole is of 408 inches = 34 ft.
Step-by-step explanation:
Each foot has 12 inches.
A 36 inch post cast a shadow of 24 inches.
This means that the shadow is [tex]\frac{24}{36} = \frac{2}{3}[/tex] of the real height.
At the same time a telephone pole cast a shadow of 22 ft 8 in.
Each feet has 12 inches, so it has:
22*12 + 8 = 272 in.
2/3 of the real height is 272 in. So
[tex]\frac{2h}{3} = 272[/tex]
[tex]h = \frac{272*3}{2}[/tex]
[tex]h = 408[/tex]
The height of the telephone pole is of 408 inches = 34 ft.
Find the slope of the line.

Step-by-step explanation:
The radius of the base of a cylinder is decreasing at a rate of 121212 kilometers per second. The height of the cylinder is fixed at 2.52.52, point, 5 kilometers. At a certain instant, the radius is 404040 kilometers. What is the rate of change of the volume of the cylinder at that instant (in cubic kilometers per second)
Answer:
7536 [tex]km^3/sec[/tex]
Step-by-step explanation:
Given that:
Rate of decreasing of radius = 12 km/sec
Height of cylinder is fixed at = 2.5 km
Radius of cylinder = 40 km
To find:
The rate of change of Volume of the cylinder?
Solution:
First of all, let us have a look at the formula for volume of a cylinder.
[tex]Volume = \pi r^2h[/tex]
Where [tex]r[/tex] is the radius and
[tex]h[/tex] is the height of cylinder.
As per question statement:
[tex]r[/tex] = 40 km (variable)
[tex]h[/tex] = 2.5 (constant)
[tex]\dfrac{dV}{dt} = \dfrac{d}{dt}\pi r^2h[/tex]
As [tex]\pi, h[/tex] are constant:
[tex]\dfrac{dV}{dt} = \pi h\dfrac{d}{dt} r^2\\\Rightarrow \dfrac{dV}{dt} = \pi h\times 2 r\dfrac{dr}{dt} \\$Putting the values:$\\\Rigghtarrow\dfrac{dV}{dt} = 3.14 \times 2.5\times 2 \times 40\times 12 \\\Rigghtarrow\dfrac{dV}{dt} = 7536\ km^3/sec[/tex]
which algebra tiles are used in this equation:
4x + 7 = 23
Answer:
4x+7=23
4.4+7=23
Step-by-step explanation:
23-7=16
16/4=4
The algebra tiles used in the equation 4x + 7 = 23 are four x-tiles, seven unit tiles, and 23 unit tiles.
To model the equation 4x + 7 = 23 using algebra tiles, we would use variable tiles (x-tiles) and unit tiles.
For the term 4x, we would use four x-tiles since the coefficient is 4.
For the term 7, we would use seven unit tiles since it is a constant.
The equal sign (=) does not have a specific tile representation; it simply indicates the equation's balance.
On the other side of the equation, for the term 23, we would represent it using 23 unit tiles.
So, the algebra tiles used in this equation would be four x-tiles, seven unit tiles, and 23 unit tiles.

Jacks father drives to work in 30 min when driving at his usual speed. When traffic is bad, he drives 30mph slower and the trip takes one hour longer. How far is Jacks Fathers work from home in miles
Answer:
The distance of Jack's Father's work from home in miles is 45 miles.
Step-by-step explanation:
a) Data and Calculations:
Normal time taken by Jack's father to drive to work = 30 minutes
Time taken when traffic is bad = 1 hour longer
Speed when traffic is bad = 30 mph slower
Distance covered when traffic is bad, with time taken as 1 hour 30 minutes = time * speed = 1.5 * 30 = 45 miles
b) Jack's father normally drives at 90 mph (45 *2), this is why it normally takes him 30 minutes between his home and workplace when the traffic is not bad. However, when traffic is bad, it takes him one hour longer and he drives at 30 mph slower.

5(x + 5y) - {2x – [3x – 3(x – 2y) + y]} simplfy
Answer:
3x+20y
Step-by-step explanation:
First write down the expression.
5(x + 5y) - {2x – [3x – 3(x – 2y) + y]}
Now, the first thing you would have to do is the first parenthesis
5(x+5y)
5x+25y
So far, the expression looks like this: 5x+25y - {2x – [3x – 3(x – 2y) + y]}
No we would do the smallest parenthesis in the expression.
Which is: (x – 2y)
But since there is nothing to simplify, we move on
Next one is [3x – 3(x – 2y) + y]
We have to do 3(x-2y) first
This is equal to: 3x-6y
So far, the expression looks like this:5x+25y - {2x – [3x – 3x-6y + y]}
The next step is still in the other parenthesis up top
Which is: [3x – 3x-6y + y]
We have to add up the x's and y's
Which is -5y
Our expression now looks like this:5x+25y - 2x-5y
Since we don't have anymore parenthesis, we look for the same letter and add or subtract them.
We have to do 5x-2x=3x
25y-5y=20y
So that means our final answer is :3x+20y
Hope this answer is correct!

X and Y are whole numbers.
X% Y finds the remainder after you divide X by Y.
For example, 7 % 3, means divide 7 by 3 and determine what is left over (7 divided by 3
equals 2 and the remainder is 1). So, 7% 3 equals 1.
Question
If X is a number. Which of the following will find the last digit of X?
For example, the last digit of 1327 is 7.
O A:X% 2
O
B:X%3
O C:X% 5
O D:X% 10
O EX% 100
Answer:
x%3
Step-by-step explanation:
The remainder of a division is the whole number, after the complete division. The expression that finds the last digit of 1327 is: [tex]X \% 10[/tex]
Given that:
[tex]X = 1327[/tex]
To do this, we simply test the given options.
[tex]X \%2 = 1327 \% 2[/tex]
When 1327 is divided by 2,
The result is 663, remainder 1
So, we have:
[tex]X \%2 = 1[/tex]
[tex]X \%3 = 1327 \% 3[/tex]
When 1327 is divided by 3
The result is 442, remainder 1
So, we have:
[tex]X \% 3 = 1[/tex]
[tex]X \% 5 = 1327 \% 5[/tex]
When 1327 is divided by 5
The result is 265, remainder 2
So, we have:
[tex]X \% 5 = 2[/tex]
[tex]X \% 10 = 1327 \% 10[/tex]
When 1327 is divided by 10
The result is 132, remainder 10
So, we have:
[tex]X \% 10 = 7[/tex]
[tex]X \% 100 = 1327 \% 100[/tex]
When 1327 is divided by 100,
The result is 13, remainder 27
So, we have:
[tex]X \% 100 = 27[/tex]
Hence, the expression that finds the last digit is: [tex]X \% 10[/tex]
Because the result is 7
