We know that the angle of a straight line is 180°.
So we know that (5x-5) + (2x+10) = 180
We will then solve for x
5x - 5 + 2x + 10 = 180
7x + 5 = 180
7x = 175
x = 25 (just an explanation of how we get 25)
To get angle 1, we will then plug in x=25 into the first equation to get
5(25)-5 = 125-5 = 120°
Answer:
The consultant sold 15 circular stones and 22 rectangular ones
Step-by-step explanation:
let quantity of circular stones be X , rectangular ones be Y
thus:,We can deduce that,
26x+34y=1138...... equation 1
He sold total of 37 ,both stones
x+y=37... equation 2
Solving simultaneously
make Y subject of the formula in equation 1
34y=1138-26x
Answer: 330
Step-by-step explanation:first you subtract 50 from 120 = 70 then 70 x the number of days which is 4 = 280 + the seashells at the beginning which is 50 = 330.
4/5 is equal to 0.8 when you divide 4 by 5. 2/3 is 0.66 when you divide 2 by 3. So 4/5 is bigger than 2/3.
