Let the number be represented by x
2x=60+ 5x -20*2=60+5*-20
2x-5x=5x-5x+60 -40=60+-100
-3x=60 -40=-40
-3x/-3=60/-3
x=-20
Therefore the number is -20
Hey there,
a-7=3(b+2), we do 3 times b and 3 times 2 according to the rule.
a-7=3b+6 we change + to - and - to + when move nums from 1 side to another one.
a=3b+13 we get the solution.
Hope this helps :)
Answer:
m∠NSR = 113°
m∠RSP = 67°
Step-by-step explanation:
Angle formed between the intersecting chords is one half the sum of the measures of the arcs intercepted by the angles.
m∠NSR = ![\frac{1}{2}[\text{arc}(NR)+\text{arc}(PQ)]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5B%5Ctext%7Barc%7D%28NR%29%2B%5Ctext%7Barc%7D%28PQ%29%5D)
= 
= 113°
Since, m∠NSR + m∠RSP = 180° [Linear pair of angles are supplementary]
113° + m∠RSP = 180°
m∠RSP = 180° - 113°
= 67°
no. he isn't correct because the scale factor is an improper fraction. 2/5 means you have 2 out of 5, but if you have 8 out of 3, that means you have 2 3s and 2 more leftover. it wouldn't be a reduction, it'd be increasing!
