Answer: 20
1) simplify 2^2 to 4
4*5
2) simplify
20
The best answer would be
2.4 x 10 ^6
10 to the sixth power multiplied by 2.4
Most likely B because one pound is equal to 6 dollars. So i think it would be x= 1 and y= 6
So put the x as the dom and 6 as the num?
Answer:
(1, 2)
Step-by-step explanation:
Given the equation of the lines x + 2y = 5 and 2x - 3y = -4
First we need to make x the subject of the formulas
For x+2y = 5
x = 5 - 2y ... 1
For 2x - 3y = -4
2x = -4+3y
x = (-4+3y)/2 ... 2
Equate 1 and 2
5 - 2y = (-4+3y)/2
2(5-2y) = -4+3y
10 - 4y = -4+3y
-4 -3y = -4-10
-7y = -14
y = 14/7
y = 2
Substitute y = 2 into 1
x = 5 = 2y
x = 5 - 2(2)
x = 5 - 4
x = 1
Hence the point where the lines meet will be at (1, 2)
Answer:
$36
Step-by-step explanation:
20x.80=16
20+16=36
