Answer:

i < u

Step-by-step explanation:

9x - 7i > 9x - 21u (subtract 9x on both sides)

-7i > -21u (divide by -7)

i < u (sign flips because of divion by a negative)

I need a second inequality/equation to figure out i.

A high school class consists of 7 seniors, 10 juniors, 12 sophomores, and 11 freshmen. Exactly 4 of the juniors are female,

jekas [21]

Answer:

1/13

Step-by-step explanation:

There exactly 7 seniors 10 Juniors, 12 sophomores and 11 freshman

in which 4 of the juniors are Female , and exactly 2 of the sophomores are male. Therefore,

10-4= 6 juniors are male

12-2 = 10 female sophomores

Total = 7+10+12+11= 40 students

P(male junior then female soph.)= $\frac{6}{40}\times\frac{10}{39}= \frac{1}{26}$

P(female soph then male junior)= $\frac{10}{40}\times\frac{6}{39}= \frac{1}{26}$

Therefore the final answer will be = 1/26 +1/26= 1/13

0.8-3.2x<-2-2.8x please help me answer this!!!!! it is timed

Xelga [282]

Answer:

x > 7

Step-by-step explanation:

0.8 - 3.2x < -2 - 2.8x

Add 2.8x to both sides.

0.8 - 0.4x < -2

Subtract 0.8 from both sides.

-0.4x < -2.8

Divide both sides by -0.4. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality symbol changes direction.

x > 7
