solve for x helpp plz !

Answer:

Yes

Step-by-step explanation:

Given expression: 3x+9

Take 3 outside from the expression, we get,

= 3(x+3), which is called the equivalent expression

Answer:

No

Step-by-step

We have to multiply the 4 by both the a and the 3 since there a parenthesis around them. This would of course be distributive property. Since you don't know what a is, it would just be 4a and since we can multiply 4 and 3 that would be 12. So, 4(a - 3) is equivalent to 4a - 12.

Answer:

A, E

Step-by-step explanation:

The mean of the pizza truck:

(400 + 800 + 1000 + 1000)/4 = 800

The mean of the burger truck:

(800 + 700 + 900 + 800)/4 = 800

A is correct, which voids answer C

The median of the pizza truck:

400, 800, 1000, 1000

              \     /

               900

The median of the burger truck

700, 800, 800, 900

            800

900>800 so E is correct, voiding all other answers

Answer:

Y=x+3

Step-by-step explanation:

Just subtract the x value from the y value and you will always get the right answer... But isn't this iready? A test?

Answer:

4 5/6

Step-by-step explanation:

4 5/6 = 29/6

5 1/6 = 31/6

29/6 + 31/6 = 60/6 = 10

9514 1404 393

Answer:

  90

Step-by-step explanation:

The number that goes in the blank is x, where ...

  0.30x = 27

Dividing by 0.30, we find ...

  x = 27/0.30 = 90

Then ...

  30% of 90 = 27

Answer:

8(2x + 5y)

Step-by-step explanation:

You cant fact (take out) 8 from both 16 and 40 since 8 is a factor for both.

Step-by-step explanation:

=16x+40y

=8(2x+5y)

Answer:

644

Step-by-step explanation:

SA=[2×(5×20 + 5×6 + 20×6)] +

[2×(4×12 + 4×6 + 12×6)] -

[ 2× 12×6]

= [2×(250)]+[2×(144)] - [144]

= 500+288-144

= 644 cm²

Answer:

D

Step-by-step explanation:

The area (A) of the triangle is calculated as

A = [tex]\frac{1}{2}[/tex] ab sinC ( a, b are the sides and C the angle between them ) , then

A = [tex]\frac{1}{2}[/tex] × 5 × 3 × sin40° = 7.5 × sin40° ≈ 4.8 units² ( to nearest tenth )

Answer:0.013

Step-by-step explanation:

Answer:

f=180-(61+87)

=180-148

=32

e=f=32

e=32

d=180-(87+32)

=61

Step-by-step explanation:

do base times height to get the area

Awnser :

Ten

Explanation :

In a relaxed practice setting with no pressure, the average player should be able to make at least ten in a row. But free throws typically come in pressure situations, so managing the pressure is as important as practicing form.

Answer: 4

Step-by-step explanation: Arrange them in number order and cross one off on the left then the right to find the middle value which should be 4

Answer:

-0.8 is the correct answer of this question

Answer:

-16/45

Step-by-step explanation:

When you mulitply these two fractions together it's best to muliteply them by the number across so therefore 8x-2= -16 and 15x3= 45 which you end up with -16/45

Step-by-step explanation:

check the pic

answer is 4

A = 11

Step-by-step explanation:

For the problem on the LHS, the 2nd line should have been written as

5(A + 1) = 3(2A - 2)

Now let's solve for A:

5A + 5 = 6A - 6

-6A - 5. -6A. - 5

______________

-A = - 11

or A = 11

This is the correct solution and it will now work out right.

Answer:

Answer: 80°

Step-by-step explanation:

Since, If two secants intersect outside the circle, then the measure of the angle formed is one half of the difference  of the measures of the intercepted arcs.

In the given diagram,

Chord VS and chord UT are intersecting externally,

Also, ∠SPT is the angle formed by the intersection of these chords.

Thus, by the above property,

⇒ Measurement of the arc VU= 80°.

Answer:

ab+ac

Step-by-step explanation:

The area of the figure is the length multiplied by the width, which is (a+b)c. By the commutative property, this is equal to c(a+b), and by the distributive property, it is also equal to ac+bc. It is not equal to ab+ac.

Answer:

c(a+b)

Step-by-step explanation:

Answer:

2167.7 sq yds

Step-by-step explanation:

SA(cone) = πr² + πrs     ('s' = slant height)

= π(15)² + π(15)(31)

= 225π + 465π

= 690π

= 2167.7

Answer:

4.87805%

Step-by-step explanation:

yuh yw

Answer:

= 4.87805% difference

Solution:

Calculate percentage difference

between V1 = 239900 and V2 = 251895

|V1−V2|[(V1+V2)2]×100=?

=|239900−251895|[(239900+251895)2]×100

=|−11995|[4917952]×100

=11995245897.5×100

=0.0487805×100
