Answer:
Step-by-step explanation:
they are opposite angles, so we put them equal to each other.
25.
6a+10= 130
6a=120 a=20 so now we plug it in 6(20) +10= 130
26. 4a-4=2a+30
2a=34 a=17 sso now we plug in 4(17)-4= 64 2(17)+30= 64
27. 6y+1=4y+9 2x-5=x+7
2y=8 x=2
y=4
now plug in 6(4)+1=25 4(4)+9=25 2(2)-5= -1 (2)+7=9
Answer:
13%
Step-by-step explanation:
the cost price of 1/3 of the sugar = 1/3 x 4500 = 1500
gain=
x 100
let x = unknown selling price
(x - 1500) / 1500 = 0.1
to solve for x, multiply both sides of the equation by 1500
x - 1500 = 150
x = 1650
the selling price of the 1/3 of sugar that yielded a 10% gain is 1650
to determine the gain percent of the remaining sugar, the selling price of the remaining sugar has to be determined . Let the selling price be represented by a
Based o the information in the question and the previous solution, the following equation can be derived
{(a + 1650) - 4500} / 4500 = 0.12
Solve for a
Multiply both sides of the equation by 4500
a + 1650 - 4500 = 540
a = 3390 = selling price of 2/3 of the sugar
Percent gain that the 2/3 of the sugar should be sold can be determined by taking the following steps
first find cost price of the 2/3 of sugar = 2/3 x 4500 = 3000
gain = (3390 - 3000) /3000 = 0.13 = 13%
0.1 x 2 = 0.2 When you multiply 0.1 and 2, you move the decimal once because there is one decimal place.
