This is incomprehensible, but I would be happy to help if you perhaps re-typed it :D
Answers + Step-by-step explanation :
a) the equation should be:
7(n + 5) = 91 since you first add 5 to n and then multiply it by 7. The answer is 91 so that is on the other side of the equal sign
b) we can solve our equation to find for n, the number jim thought of
7(n + 5) = 91
I will use the distributive property.
7n + 35 = 91
Subtract 35 on both sides
7n = 56
Now divide 7 on both sides to find n
n = 8
The number Jim was thinking of was 8! this should be correct, hope this helps!
∠A = 180° - (63°+101°)=16°
sine's rule
Angle Y is a right angle, so it’s 90 degrees. Angle W is 2x, since it’s opposite angles on a single line intersecting parallel lines. Triangles have 180 degrees, so adding up all sides creates the equation to solve:
X+Y+W=180
(3x-5)+90+2x=180
5x+85=180
5x=95
x=19
Factor x^2 + 6x - 27 using the AC method.
(x - 3)(x + 9)
Hope this helps! :)
