Answer:

45

Step-by-step explanation:

solution

90+2x=4x

or,90=4x-2x

or,2x=90

or,x=90÷2

ans x=45

Answer:

[tex]90 + 2x = 4x \\ \\ 90 = 4x - 2x \\ \\ 90 = 2x \\ \\ x = \frac{90}{2} \\ \\ x = 45 \\ [/tex]

She needs to get 27/30 right.

Step-by-step explanation:

Answer:

x=10

Step-by-step explanation:

Set up the equation, (3x+6)+54=90 because both angles equal up to 90 degrees, and then solve for x.

Answer:

x=10

Step-by-step explanation:

(3x+6)+54=90

3x+6=36

3x=30

x=10

Answer:

-8

Step-by-step explanation:

Solve the equation:

-2m = 8 - m

-2m + m = 8

-m = 8

m = -8

If you would like to check the answer, plug the value of m back into the equation:

-2 (-8) = 8 - -8

16 = 16

Answer:

m = -8

Step-by-step explanation:

add m to both sides

-2m + m =8 - m + m

simplify

-m = 8

divide sides by -1

-m/-1 = 8/-1

simplify

m = -8

Answer:

n= -12

Step-by-step explanation:

Solve for n by simplifying both sides then isolating the variable.

Given :

C, D, and E  are col-linear, CE = 15.8 centimetres, and DE=  3.5 centimetres.

To Find :

Two possible lengths for CD.

Solution :

Their are two cases :

1)

When D is in between C and E .

.                   .           .

C                  D          E

Here, CD = CE - DE

CD = 15.8 - 3.5 cm

CD = 12.3 cm

2)

When E is in between D and C.

.       .                .

D      E              C

Here, CD = CE + DE

CD = 15.8 + 3.5 cm

CD = 19.3 cm

Hence, this is the required solution.

Step-by-step explanation:

In this case we have the plane P and the plane with B, C, D points on it

The intersection line is BC as we see on the picture

Answer:

I think it is A

Step-by-step explanation:

a is called the real part of the complex number and bi is called the imaginary part of the complex number. In the complex number 6 - 4i, for example, the real part is 6 and the imaginary part is -4i.

Answer:

The following properties hold for all events A, B.

• P(∅) = 0.

• 0 ≤ P(A) ≤ 1.

• Complement: P(A) = 1 − P(A).

• Probability of a union: P(A ∪ B) = P(A) + P(B) − P(A ∩ B).

For three events A, B, C:

P(A∪B∪C) = P(A)+P(B)+P(C)−P(A∩B)−P(A∩C)−P(B∩C)+P(A∩B∩C).

If A and B are mutually exclusive, then P(A ∪ B) = P(A) + P(B).

• Conditional probability: P(A | B) = P(A ∩ B)

P(B)

.

• Multiplication rule: P(A ∩ B) = P(A | B)P(B) = P(B | A)P(A).

• The Partition Theorem: if B1, B2, . . . , Bm form a partition of Ω, then

P(A) = X

m

i=1

P(A ∩ Bi) = X

m

i=1

P(A | Bi)P(Bi) for any event A.

As a special case, B and B partition Ω, so:

P(A) = P(A ∩ B) + P(A ∩ B)

= P(A | B)P(B) + P(A | B)P(B) for any A, B.

• Bayes’ Theorem: P(B | A) = P(A | B)P(B)

P(A)

.

More generally, if B1, B2, . . . , Bm form a partition of Ω, then

P(Bj | A) = P(A | Bj )P(Bj)

Pm

i=1 P(A | Bi)P(Bi)

for any j.

• Chains of events: for any events A1, A2, . . . , An,

P(A1∩A2∩. . .∩An) = P(A1)P(A2 | A1)P(A3 | A2∩A1). . . P(An | An−1∩. . .∩A

Answer:

b

Step-by-step explanation:

The decimal number 3.4 terminating decimal. So, it is rational number. Therefore, option B is the correct answer.

Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

A) The decimal number 3.456733244… is not repeating and non recurring

So, it is irrational number

B) The decimal number 3.4 terminating decimal

So, it is rational number

C) Infinity is not a rational number because it is undefined as far as being an integer.

D) ∛4 =1.58740105197 is not repeating and non recurring

So, it is irrational number

The decimal number 3.4 terminating decimal. So, it is rational number. Therefore, option B is the correct answer.

Answer:

The cargo plane flew 1208 miles, and it took 4 hours.

Step-by-step explanation:

4608 miles is the distance between the passenger plane and the cargo plane.

This distance can be expressed as the sum of the distance that the passenger plane had flown and the distance that the cargo plane had flown.

Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)

So, to find the distance flown by the cargo plane, we need both the distance between the 2 planes and the distance flown by the passenger plane.

We know that the distance apart is 4608 mi.

We can find the distance flown by the passenger plane by multiplying its speed by the time it was flying.

[tex]distance = speed * time[/tex]

Speed = 425 mph

Time = 8 hours

[tex]distance\ (passenger) = 425 * 8\\distance\ (passenger) = 3400[/tex]

The passenger plane flew 3400 mi.

Now we can find the distance flown by the cargo plane:

Distance Apart = Distance Flown (Passenger) + Distance Flown (Cargo)

[tex]4608 = 3400 + distance[/tex]

Subtract 3400 from both sides:

[tex]1208 = distance[/tex]

The cargo plane flew 1208 miles.

If we want to find for how long it flew, we can divide the distance by its speed.

[tex]distance = speed * time[/tex]

[tex]time = \frac{distance}{speed}[/tex]

Distance = 1208 mi

Speed = 302 mph

[tex]time = \frac{1208}{302} = 4[/tex]

Answer: The cargo plane flew 1208 miles, and it took 4 hours.

Answer:

23

Step-by-step explanation:

If you have something that says it is the f(x) or just f(something) then that is just telling you what the x equals. In this case, x=4 so you plug that into the equation.

This gives you f(4)=4(4)+7. From here, you will use the order of operations to solve.

f(4)=4*4+7

f(4)=16+7

f(4)=23

Answer:

f(4)=23

Step-by-step explanation:

1.f(4)=4(4)+7

2.f(4)=16+7

3.f(4)=23

Answer:

-30

Step-by-step explanation:

0,4x +2,5=0,2x - 4

0,4x - 0,2x =-4 - 2

0,2x =-6

x=-6 :0,2

x=-30

Hey there!

Your answer would be -32.5.

First, you would multiply both sides by 10, and simplify. That would bring you to 4x + 25 = 2x - 40. Now you can start isolating the varible. Subtract 25 from both sides, and simplify. That gives you 4x = 2x - 65. Next, subtract 2x from both sides, and simplify once again. That brings you to 2x = -65. Finally, divide both sides by 2 and once more, simplify. It gives you your answer x=-65/2 or -32.5

Answer:

u=2

Step-by-step explanation:

8u-21 = 2u-9

+21             +21

8u= 2u + 12

-2u    -2u

6u= 12

divide by 6, u=2 !!

Answer:

u = 2

Step-by-step explanation:

8u - 21 = 2u - 9

subtract 2 u from both sides

6u - 21 = -9

add 21 to both sides

6u = 12

divide both sides by 6

u = 2

Answer:

2.5(x)+6=3.25(x)+3 4=x. Real world problem below

Step-by-step explanation:

Nico is organizing a party. Going skating, admission is 6 dollars, and each person pays 2.5 dollars for a pair of skates. If he has 3 other people in his group, the equation is 2.5(4)+6=24. He is also looking at going to a trampoline park. It is 3 dollars to get in, and 3.25 per person for an hour on the trampolines. This equation can be shown as 3.25(4)+3 which equals 24.
