-36+7x=76-x please solve for x

Answer:

step 1

Step-by-step explanation:

Given

(x - 2)(3x + 4) ← apply distributive property

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

                        ↑ error is here , she put (x + 2)

In this exercise we have to use the knowledge of the distributive property, so In alternative 1 she made the mistake.

The distributive property is used when a number is multiplying an addition or subtraction. Simply multiply each term separately and add or subtract the result. We distribute the multiplication of the 2, to the 8 and to the 3.

Proving the mistake:

[tex](x - 2)(3x + 4) \\= (X)(3x) + (-2)(3x) + (x)(4) + (2)(4)\\and not\\(x-2)(3x) + (x + 2)(4)[/tex]

Answer:

Miguel walks 4.25 blocks more than Jila.                      

Step-by-step explanation:

Line plot shown in the question represents the distance traveled by the students from their houses to their school.

From the line plot,

Distance between 1 and 2 = [tex]\frac{1}{4}[/tex] = 0.25 blocks

Shortest distance traveled by Miguel = 0.25 blocks

Longest distance traveled by Jila = 4.5 blocks

Difference between the distances covered by Miguel and Jila = 4.5 - 0.25

= 4.25 blocks

Therefore, Miguel walks 4.25 blocks more than Jila.

Answer:

7, 8, 11, 11, 18

Step-by-step explanation:

The order you put them in is from least to greatest:

7, 8, 11, 11, 18

There, you can find the median to be 11

Answer:

It is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list. To find the mean, add up all the values in the set. Then divide the sum by how many values there are. That is the mean.

Step-by-step explanation:

X: -2,-1,0,1,2

Y: 18,14,10,6,2

Solution :

It is given that Little Snail is going to visit one of his friend at the pond which is 3 miles away.

When the snail crawls 1/2 of a mile per day, it will take him, [tex]$1 \times \frac{2}{1} \times 3$[/tex]

   =  6 days to get to the next pond.

When the snail crawls 1/3 of a mile per day, it will take him, [tex]$1 \times \frac{3}{1} \times 3$[/tex]

   =  9 days to get to the next pond.

When the snail crawls 1/4 of a mile per day, it will take him, [tex]$1 \times \frac{4}{1} \times 3$[/tex]

   = 12 days to get to the next pond.

When the snail crawls 3/4 of a mile per day, it will take him, [tex]$1 \times \frac{4}{3} \times 3$[/tex]

   =  4 days to get to the next pond.

When the snail crawls 2/3 of a mile per day, it will take him, [tex]$1 \times \frac{3}{2} \times 3$[/tex]

   =  4.5 days to get to the next pond.

Answer:

F is  not congruent

Step-by-step explanation:

1 : 1.71 : 2.43

Step-by-step explanation:

What divided by 7= 1?

7/7 = 1

So use that answer for the other two dolls.

12/7 = 1.71

17/7 = 2.43

1 : 1.71 : 2.43

Have the same ratio as

7 : 12 : 17

Answer:

y-8=-1×(x+0)

Step-by-step explanation:

m=y2-y1/x2-x1

m=0-(8)/8-(0)

m=-8/8-(0)

m=-8/8+0

m=-8/8

m=-1

y-(8)=-1×(x-(0))

y-8=-1×(x+0)

Answer:Who is BRIANNA

Step-by-step explanation:

Answer: $4,813.24

Step-by-step explanation:

This requires the use of a future value formula because we are to find the value of an amount in future after compounding it over a certain period.

Future Value = Amount * (1 + rate) ^ number of years

= 2,000 * ( 1 + 5%)¹⁸

= $4,813.24

In 18 years, the $2,000 would have increased to $4,813.24.

Answer:

18

Step-by-step explanation:

Should be D. if I'm correct. This pair of angles doesn't seem to be in the right position to form a 90 degree or a 180 degree angle, ruling out supplementary and complementary angles, and they definitely aren't vertical angles, leaving only choice D: None of the above.

Answer:

Angle of elevation = 48.60° (Approx.)

Step-by-step explanation:

Given:

Vertical Height = 150 feet

Horizontal angular length of drone = 200 feet

Find:

Angle of elevation

Computation:

Using trigonometry function

⇒ Sinθ = Perpendicular / Hypotenuse

⇒ Sinθ = Vertical Height / Horizontal angular length of drone

⇒ Sinθ = 150 / 200

⇒ Sinθ = 0.75

⇒ Sin⁻¹(0.75) = θ

Angle of elevation = 48.60° (Approx.)

Answer:

65.60

Step-by-step explanation:

Formula :

Distance between two points = √(xB−xA)2+(yB−yA)2(xB-xA)2+(yB-yA)2

Solution :

Distance between two points = √(30−−22)2+(−25−15)2(30--22)2+(-25-15)2

= √522+(−40)2522+(-40)2

= √2704+16002704+1600

= √43044304 = 65.6049
