Answer:Joan's height is 127 centimetres

Step-by-step explanation:

 Step 1

Joan  is  4 feet 2 inches tall and we want to change to centimeters .

we first change her height to inches

1 Foot = 12 Inches

Therefore  4 Feet = 4 x 12 = 48 inches

Total height in inches =48 inches + 2 Inches = 50 inches

Step 2 --Now, we have gotten her height in inches, we can now  change  to centimetres.

We have that

 1  inch =2.54 centimeters

50inches = 50 x 2.54 cm

=127 centmeters.

Joan's height is 127 centimetres

an oil company drilled several walls.fifty wells, or 25%,produced oil.what was the total number of wells that were drilled
Phantasy [73]
25% is equal to 100/25=1/4

We can substitute this into an equation to get the total number of wells where n can be equal to the total number of wells.

1/4*n=50
n/4=50
n=50*4
n=200

The total number of wells that were drilled was 200.

Determine which of the following statements is NOT correct. 00:00 The equation x + 1.793 = 2.42 can be rewritten as x-1.793 = 2.
Mademuasel [1]

• x+1.793= 2.42

x-1.793= 2.42-1.793 FALSE

• 5.25x = 15.75

Solve for x, by dividing both sides of the equation by 5.25

x = 15.75/5.25

x = 3 TRUE

• The equation x = 2.4 *11.62 can be rewritten as x = 11.62 * 2.4. TRUE

• The solution to the equation x + 9.43 = 16.09 is x = 6.66.​

x+9.43 = 16.09

Subtract 9.43 from both sides of the euqation:

x-9.43+9.43= 16.09-9.43

x = 6.66 TRUE

<u>Correct Question</u>

In the table shown, the sum of each row is shown to the right of the row and the sum of each column is shown below the column. What is the value of L?

\left|\begin{array}{c|c|c|c}-&-&-&-\\J&K&J&5\\K&K&L&13\\L&J&L&15\\-&-&-&-\\11&7&15\end{array}\right

Answer:

L=7

Step-by-step explanation:

From the first row: 2J+K=5

Therefore: K=5-2J

From the second column, 2K+J=7

Substitute K derived above into 2K+J=7

2K+J=7

2(5-2J)+J=7

10-4J+J=7

-3J=7-10

-3J=-3

J=1

Recall: K=5-2J

K=5-2(1)=3

K=3

From the third column, J+2L=15

1+2L=15

2L=15-1=14

L=7

Therefore, the value of L=7

CHECK:

\left|\begin{array}{c|c|c|c}-&-&-&-\\1&3&1&5\\3&3&7&13\\7&1&7&15\\-&-&-&-\\11&7&15\end{array}\right
