Answer:
x = 3 , y = 4
Step-by-step explanation:
5x + y = 19 --------- ( 1 )
=> y = 19 - 5x
7x - 2y = 13 ------------ ( 2 )
Substitute y in ( 2 ) :
7x - 2( 19 - 5x ) = 13
7x - 38 + 10x = 13
17x = 13 + 38
17x = 51
x = 3
Substitute x in ( 1 ) :
5x + y = 19
5( 3 ) + y = 19
15 + y = 19
y = 19 - 15
y = 4
8.6 because 8 is bigger than 6
What statements are there? (If there are 3 batches, you'd have 1 cup of milk, just FYI).
PART A
move 2/3 to the right side so we could find the value of A
(2/3)A = -24
A = -24 ÷ 2/3
A = -24 × 3/2
A = -72/2
A = -36
Point A is -36
PART B
move -0.2 to the other side so we could find the value of B
-(B)/0.2 = 20
-B = 20 × 0.2
-B = 4
B = -4
Point B is -4
PART C
Find the distance between -36 and -4
d = |-36 - (-4)|
d = |-36 + 4|
d = |-32|
d = 32
The distance of the two points is 32
Answer:
$11 and $16
Step-by-step explanation:
let x be the cost of a student ticket then an adult ticket is x + 5 , then
3x + 7(x + 5) = 145 , that is
3x + 7x + 35 = 145
10x + 35 = 145 ( subtract 35 from both sides )
10x = 110 ( divide both sides by 10 )
x = 11
Student ticket costs $11 and adult ticket = x + 5 = 11 + 5 = $16
