If you do 22÷9 and see the hole number: 2. Then do 2 x 9 and you get 18. Now do 22-18 and you get 4. So do 2 4/9. Always have the denominator stay the same.
Answer:
<h2>
50°</h2>
Step-by-step explanation:
AB = AC
So, it is a isosceles triangle.
<B = <C = 65°
Sum of angles of triangle = 180°
< A + < B + <C = 180°
plug the values:
X + 65° + 65° = 180°
Calculate the sum
X + 130° = 180°
Move constant to R.H.S and change its sign
x = 180° - 130°
Calculate the difference
X = 50°
Hope this helps...
Good luck on your assignment...
In December she would have saved $1585 because 1235 + 250 = 1485. You can find how much money she raised in those 2 months by adding the totals of both months together, so 1485 + 1235 = 2720. She saved $2720 in the 2 months.
X= width
length= 3x-7
Area: (x)(3x-7)=40
= 3x^2-7x=40
= 3x^2-7x-40=0
Factorise the equation: (3x+8)(x-5)=0
x=-8/3 (reject because width cannot be negative) or x=5
so width is 5cm and length is 3(5)-7= 8cm !
