Answer:
(2, 5)
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
- 2x + y = 1 → (2)
Substitute y = x + 3 into (2)
- 2x + x + 3 = 1
- x + 3 = 1 ( subtract 3 from both sides )
- x = - 2 ( multiply both sides by - 1 )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = 2 + 3 = 5
Solution is (2, 5)
Answer:
Density is directly related to the mass and the volume. In fact, it tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume. If the mass has a large volume, but a small mass it would be said to have a low density.

Answer:
x<2
Step-by-step explanation:
multiply 5 by the numbers inside the parenthesis
5x-10<-3x+6
add 10 to both sides
5x-10+10<-3x+6+10
simplify
5x<-3x+16
add 3x to both sides
5x+3x<-3x+16+3x
simplify
8x<16
divide by 8
8x/8 < 16/8
x<2
To solve for X: First you multiply x and 6 then subtract 21 on both sides and then divide by 6
531 = ( X × 6) + 21
531 = 6X + 21
510 = 6X
85 = X
