Answer:
1) x = 48/35, -57/35
2) x = -48/35, 57/35
Step-by-step explanation:
|2 1/3 x+0.3|=3.5
7/3x + 0.3 = 3.5
7/3x = 3.2
x = 48/35 or 1.37
7/3x + 0.3 = -3.5
7/3x = -3.8
x = -57/35 or -1.63
Answers:
x = 48/35, -57/35
|2 1/3 x-0.3|=3.5
7/3x - 0.3 = 3.5
7/3x = 3.8
x = 57/35 or 1.63
7/3x - 0.3 = -3.5
7/3x = -3.2
x = -48/35 or -1.37
Answers:
x = -48/35, 57/35
Boys = 4
Children = Boys + Girls = 4 + 2 = 6
This means that the ratio of boys to children is 4:6
You can also simplify this to 2:3
In this case, this means that for every 3 children, 2 of them will be boys.
4x+y=26 replace y with (x-4) & solve for x in this equation.
4x+(x-4)=26
4x+x=26+4
5x=30
x=30/5 <span>
x=6 answer.
y=6-4
y=2 answer.
Proof.
4*6+2=26
24=2=26
</span>26=26 <span>Y=x-4
</span>
Y · y = y²
when multiplying exponents, you add them together
