Answer:
Decimal - 0.4
Fraction - 2/5
Step-by-step explanation:
A) 2(5x-3)=24
*Distribute the 2*
10x-6=24
*Add 6 to both sides*
10x=30
*Divide both sides by 10*
ANS: x=3
b) 5(2x+1)=50
*Distribute the 5*
10x+5=50
*Subtract 5 from both sides*
10x=45
*Divide both sides by 10*
x=45/10
*Simplify by dividing numerator and denominator by GCF (5)
ANS: x=9/2
Hope this makes sense!
The answer is A.20. you just add the two sides up
Into the equation y=−3x+b substitute 5 for x and 2 for y, obtaining:
2 = -3(5) + b. Then 2 = -15 + b, or b = 17.
