Answer:
s = 180
Step-by-step explanation:
s is the total number of seventh-grade students
1/10s take French which is 18
1/10s = 18
s = 18(10)
s = 180
Evaluate: 2(1/4) + 2/5 ÷ (-1/2) - 1/4
⇛9/4 + 2/5 ÷ (-1/2) - 1/4
Take the LCM of the 4 and 5 is 20.
Again, 2 and 4 is 4.
⇛[(54+8)/20] ÷ [(-2 - 1)/4]
⇛62/20 ÷ (-3/4)
⇛62/20 × 4/-3
⇛62/{5*(-3)}
⇛62/-15.
Answer:
Option B and D
Step-by-step explanation:
Multiply 80 by 1/10
Divide 80 by 10
I can't explain it with words so here's the equation, hopefully you understand:
875/125=7
I think you should try your best and just never get but just always keep trying because if you give up that means you're not track so just keep trying and get it right.
