Lets say you are x
20<2x<40
therefore x has to be greater than 10, but less than 20
6x=_8
the only numbers between 10 and 20 that works with this equation are 13 and 18
(6x13=78 and 6x18=108)
Multiple: 4 * 1
/2 = 4 · 1 = 4
/2 = 2 · 2
1 · 2 1 · 2 = 2
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(4, 2) = 2
Multiple: 7 * 2 = 14
Multiple: 5 * 1
/3 = 5 · 1
1 · 3 = 5
/3
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(5, 3) = 1
Multiple: 3 * 5
/3 = 3 · 5
1 · 3 = 15
/3 = 5 · 3
1 · 3 = 5
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(15, 3) = 3
Add: 14 + 5 = 19
Multiple: -3 * 1
/2 = -3 · 1
1 · 2 = -3
/2
= -1.5 · 2
1 · 2
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-3, 2) = 2
Multiple: 1/2 * (-3
/2
) = 2 · (-3)
1 · 2 = -6
/2 = -3 · 2
1 · 2 = -3
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-6, 2) = 2
Add: 19 + (-3) = 16
7(4×1/2) + 3(5×1/3) + 2(-3×1/2) = 16
/1 = 16
Answer for your question is on the picture below
Hey there!
4x + 7 + 35 = 90°
4x + 42 = 90°
SUBTRACT 42 to BOTH SIDES
4x + 42 - 42 = 90 - 42
CANCEL out: 42 - 42 because it give you 0.
KEEP: 90 - 42 because it help solve for the x-value.
NEW EQUATION: 4x = 90 - 42
SIMPLIFY IT!
4x = 48°
DIVIDE 4 to BOTH SIDES
4x/4 = 48/4
CANCEL out: 4/4 because it give you 1
KEEP: 48/4 because it give you the x-value
NEW EQUATION: x = 48/4
SIMPLIFY IT!
x = 12
Therefore, your answer is: x = 12
Good luck on your assignment & enjoy your day!

I'm not too sure about this one but if you find 3% of $200 you get 6 and if you multiply that by 2 ( for the 2 years ) you'll get ( A $12 )
