Answer:
Length = 14 m, Width = 7 m
Step-by-step explanation:
Let the length is l and width is b.
Width, b = l-7
Area of the rectangle, A = 98 m²
We know that, the area of a rectangle is as follow :
So,
Length can't be negative. So,
Width, b = 14-7 = 7 m
So, the dimensions of the rectangle are 14 m and 7 m respectively.
Answer:
x = -0.2
Step-by-step explanation:
Cross multiply
9* 0.2(6x + 1) = 3.6 * 0.5x Combine the coefficients on the right.
1.8 (6x + 1) = 1.8 x Remove the brackets on the left
1.8*6x + 1.8 = 1.8x Multiply the factors on the left. Don't do anything with the plus sign
10.8x + 1.8= 1.8x Subtract 1.8 from both sides
10.8x = 1.8x - 1.8 Subtract 1.8x from both sides
10.8x - 1.8x = -1.8
9x = - 1.8 Divide by 9
x = -1.8/9
x = - 0.2
Check
This is one question you should check. There's lot's of room for an error.
<em><u>LHS</u></em>
0.2(6x+1)/3.6
0.2(6 * -0.2 + 1) / 3.6
0.2( - 1.2 + 1) / 3.6
0.2( - 0.2) / 3.6
- 0.04 / 3.6
- 0.011111111
<em><u>RHS</u></em>
0.5 ( - 0.2)/9
-0.1/ 9
- 0.0111111 And the left and right side check.
This as a mixed number is 1 4/5 because when we do 9/1 x 1/5 it gets us 9/5. We have to change 9/5 as a mixed by seeing how much times the numerator which here is 1, and how much nummbers are left over so 4 and we leave the denominator as 5, so we get 1 4/5
Answer:
(1,3),(1,4),(1,5),(1,6),(2,3),(2,4),(2,5)
Step-by-step explanation:
x+y<8. Let y=1, then x=(3, 4,5,6). If y=2, x=(3, 4,5).
Answer:
C, 360
Step-by-step explanation:
Interior angle sums can be found using the equation (N=-2)*180, where N equals the number of sides of the polygon.
