Answer:
h
Step-by-step explanation: h
(-3/8)(+8/15)
Answer will be a negative number. Whenever multiplying a - negative number * a + positive = - negative number.
(-3/8)(+8/15)
Cross out -3 and 15 . Divide by 3. -3/3,=-1 15/3
= -1/5
Cross out 8 and 8. Divide by 8.
8/8= 1 , 8/8= 1
-1/5*1/1= -1/5
Answer : -1/5
Answer:
w = 13
Step-by-step explanation:
Using the method of cross- multiplying
• 
= 
⇒ ad = bc, thus
42(w + 11) = 28(w + 23) ← distribute parenthesis on both sides
42w + 462 = 28w + 644 ( subtract 28w from both sides )
14w + 462 = 644 ( subtract 462 from both sides )
14w = 182 ( divide both sides by 14 )
w = 13
Step-by-step explanation:
- Divide both sides of the equation by the same term
6m/6 =12/6
- Cancel terms that are in both the numerator and denominator
- Divide the numbers
m=2
