Answer:

Step-by-step explanation:

Consider the smaller than sign as smaller or equal to sign as I couldn,t type the sign

-4(x+3)<-2-2x

Expand the bracket

-4x-12<-2-2x

Add 2x to both sides

-2x-12<-2

Add 12 to both sides

-2x<10

add 2x to both sides

0<10+2x

minus 10 on both sides

-10<2x

SImplify

-5<x

X is larger or equal to -5 which means the option A

What is the answer of 5.21 + 0.6-0.27/3

ruslelena [56]

5.21 + 0.6 - (0.27 / 3) I assume this is the right equation
5.21 + 0.6 = 5.81
0.27 / 3 = 0.09
5.81 - 0.09 = 5.72

barxatty [35]

Answer:

Part 6)

case a) $P(odd)=\frac{1}{2}=0.5=50\%$

case b) $P(less\ than\ 3)=\frac{0}{8}=0=0\%$

Part 7)

case a) $P(yellow)=\frac{3}{20}=0.15=15\%$

case b) $P(green\ and\ red)=\frac{1}{20}=0.05=5\%$

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

Let

x------> size of the event space

y-----> size of the sample space

$P=\frac{x}{y}$

Part 6)

case a) P(odd)

In this problem we have

$x=4$

$y=8$

substitute

$P=\frac{4}{8}=\frac{1}{2}=0.5=50\%$

case b) P (less than 3)

In this problem we have

$x=0$

$y=8$

substitute

$P=\frac{0}{8}=0=0\%$

Part 7)

case a) P(yellow)

In this problem we have

$x=3$

$y=20$

substitute

$P=\frac{3}{20}=0.15=15\%$

case b) P(green and red)

$P(green)=\frac{5}{20}$

$P(red)=\frac{4}{20}$

therefore

$P(green\ and\ red)=\frac{5}{20}*\frac{4}{20}=\frac{20}{400}=\frac{1}{20}=0.05=5\%$

A jet left Paris at the same time as a

Anni [7]

Answer:

The speed of the jet is 410 mph.

Step-by-step explanation:

The jet and the passenger plane flew in opposite directions.

Given that the passenger plane flew at a speed of 450 mph, then after 11 hours, the passenger plane will fly (450 × 11) = 4950 miles.

Again, given that after 11 hours the passenger plane and the jet are 9460 miles apart.

Therefore, in 11 hours the jet flew (9460 - 4950) = 4510 miles.

Hence, the speed of the jet is $\frac{4510}{11} = 410$ mph. (Answer)

An angle measures 130° less than the measure of its supplementary angle. What is the measure of each angle?

seropon [69]

Answer:

Angle one is 130 degrees and angle two is 50 degrees

Step-by-step explanation:

You can get this answer by knowing that supplementary angles equal 180 degrees in total. So if one angle is 130 degrees less you take that and subtract it from 180 to get 50 degrees as the second angle.
