Hello,
let x the first angle
5x the second
2/3 x the third
x+5x+2/3x=180
==>20x/3=180
==>x=27 (°)
5x=5*27=135
2/3*x=2/3*27=18
27+135+18=180
scale factor is
1 inch -> 1 foot
174 inch -> 174 ×1 = 174 feet
so length of scaled model of car would be 174 feet
Answer:
y = -1 , x = 4
Step-by-step explanation:
(4x - 5y = 11) x8
(8x - 5y = 27) x4
32x - 40y = 88
- - -
32x - 20y = 108
[0. 20y = -20] divide both by 20
y = -1
8x - 5y = 27
8x - 5(-1) = 27
8x = 27 + 5
8x = 32 ( divide both by 8)
x = 4
Answer:
t =2 years
Step-by-step explanation:
P = 2400
Rate of interest = r = 5 %
I = Interest = 240
Prt = I
![\dfrac{2400*5*t}{100}=240\\\\\\24*5*t=240\\\\t= \dfrac{240}{24*5}\\\\](https://tex.z-dn.net/?f=%5Cdfrac%7B2400%2A5%2At%7D%7B100%7D%3D240%5C%5C%5C%5C%5C%5C24%2A5%2At%3D240%5C%5C%5C%5Ct%3D%20%5Cdfrac%7B240%7D%7B24%2A5%7D%5C%5C%5C%5C)
t = 2 years
LHS=2^2+11+15
=4+11+15
=30
RHS=(3)(something that gives us 30 when multiplied by 10)
Therefore the answer is 10 (3*10=30)
