Answer:
A.
1. x = 6
2. x = 4
3. x = 2
B.
1. -2, -5, -10
2. 4, 8 , 20
Learning task 2
1. 6x
2. 3x
3. 2/3x = 72
4. 2x + 1 = 29
5. 4x + 8 = 54
B.
1. y < 100
2. y[tex]\leq[/tex]300,000
3. y[tex]\geq[/tex]20,000.00
4. 2y[tex]\geq[/tex]80
5. 2y < 90
Step-by-step explanation:
A.
1. x + 2 = 8, so x = 6
2. 3x = 12, so 12/3 = 4
3. 2x - 3 = 1, so 2x = 4, x = 2
B.
1. x is less than -1, so possible values of x are -2, -5, -10
4. x minus 4 is greater than -1, so x is greater than 3. Possible values of x are 4, 8, 20
Learning task 2.
1. Perimeter = 2(l+w), given that l = 2w. Let's say w=x. 2(x + 2x) = 2(3x) = 6x
2. Perimeter = 3*side. side = x, so 3x is the answer.
3. 2/3 of x is 72. 2/3x = 72
4. x is the number. x + 1 is the consecutive integer. x + x + 1 = 29, 2x + 1 = 29
5. 4x + 8 = 54
B.
1. Not less means <. y < 100
2. At most is [tex]\leq[/tex]. y[tex]\leq[/tex]300,000
3. At least is [tex]\geq[/tex]. y[tex]\geq[/tex]20,000.00
4. 2y[tex]\geq[/tex]80
5. 2y < 90
Hope this helps :)
Have a nice day!
