Equation 1 is 2W - 6 = L
equation 2 is 140= W * L
L=10
W=8
Answer:
Step-by-step explanation:
x + 2y = 14 ...............(1)
6x + 3y = 21 ..............(2)
Solve for x in equation 1
When x + 2y = 14
Therefore x = 14 - 2y ...................(3)
Now put equation 3 in equation 2 and solve
6x + 3y = 21 .............(2)
6(14 - 2y) + 3y = 21
Open the bracket and resolve
84 - 12y + 3y = 21
-9y + 84 =21
Now collect the like terms
-9y + 84 = 21
-9y = 21 - 84
-9y = -63
Divide through by -9 to get y
y = -63/-9
y = 7
Substitute for y in equation( 3 )to x
x= 14 - 2y............(3)
So, x = 14 - 2(7)
x = 14 - 14
x = 0.
Therefore x = 0 and y = 7
Check: From equation (1)
x + 2y = 14
Now, put x = 0 and y = -2
Therefore, 0 +2(7) =14
0 +14 = 14
Answer:
Pic attached.
Step-by-step explanation:
Your slope is 
and your y-intercept is -3. Plot your y-intercept on the y axis at -3 and then go up 3 and over 2, plot another point.

Answer:
5 tens and 8 ones gives 58
Step-by-step explanation:
We have to describe 58 as a sum of tens and ones
We know that first digit from the right is the ones place
Second digit is the tens place
Hence, 5 tens and 8 ones gives 58
Also, we can see that
10+10+10+10+10=50 (5 tens)
and 1+1+1+1+1+1+1+1=8 (8 ones)
on adding both we get 58
Hence, 5 tens and 8 ones gives 58
The measure of CB from the given figure is 8cm
<h3>What is a triangle?</h3>
A triangle is 2 dimensional shape with 3 sides and angles. The types of triangle that we have are;
- Equilateral triangle
- Scalene triangle
- Isosceles
The given triangle is a scalene triangle since <u>none of the sides are equal</u>
From the figure shown, we can see that the mea<em>sure of DF is equivalent to CE and EB</em>
Since CB = CE + EB
Given the following parameter
DF = 4cm
CE = EB = DF = 4cm
Substitute
CB = 4cm + 4cm
CB = 8cm
Hence the measure of CB from the given figure is 8cm
