Answer:

6

Step-by-step explanation:

3+6=9 9x7=63

Answer: 6

Step-by-step explanation:

You can set the unknown number as x and then you would add 3 to x and multiply that by 7.

The equation would be 7(x+3)=63

7(x+3)=63

7x+21=63

7x=42

x=6

The answer is 6

Answer:

Step-by-step explanation:

Check the attached diagram... since they are parallel lines, those angles should be equal. now as per the theorem of opposite angles, (3x + 10)° should be equal to 70° .

(3x + 10)° = 70°

3x = 60°

x = 20

Answer:

The number of rabbits Katniss caught = 10 rabbits

Step-by-step explanation:

The number of squirrels Katniss caught = 3 × (The number of deer she caught)

The number of rabbits Katniss caught = The number of squirrels she caught - 5

The total number of animals she caught = 10 + 4 × (The number of deer she caught)

Let the number of deer Katniss caught = D

∴ The number of squirrels she caught = 3×D

The number of rabbits Katniss caught =  3×D - 5

The total number of animals she caught = 10 + 4 × D

Therefore, we have;

The number of squirrels she caught + The number of deer she caught + The number of rabbits she caught = 10 + 4 × D

3×D + D + 3×D-5 = 10 + 4 × D

7·D - 5 = 10 + 4·D

7·D - 4·D = 10 + 5

3·D = 15

D = 15/5 = 5

∴ The number of deer Katniss caught = D = 5

The number of rabbits Katniss caught =  3×5 - 5 = 10

The number of rabbits Katniss caught = 10 rabbits.

Answer:

the points: (8,5) (6,4) (4,3) (2,2) (0,1) (-2,0) (-4,-1) (-6,-2) (-8,-3)

Step-by-step explanation:

the point (4,3) should be dotted first, start from the (0,0) go right 4 spaces then up 3 spaces. the slope 1/2 means up 1 space then right two spaces to start plotting points on the graph. and to continue the bottom of the line it would be -1/-2 which is down 1 space then left 2 spaces.

Answer:

B would be the answer

Step-by-step explanation:

If you reflect the triangle ABC onto EDC then you will see that they are congruent and equal.  

this means that <ABC ~ <EDC

The AA postulate states that if two corresponding angles of two or more triangles are congruent then the triangles are similar.   If you translate ABC onto EDC you can see that all of the angles let alone two are all congruent thus proving that ABC = EDC

Pls mark brainliest if I helped.. Thanks:)

Option (B) is the correct answer.

According to the AA postulate, triangles are comparable if two matching angles of two or more triangles are congruent.

Given that,

∠ABC = 45° and ∠ECD = 45°

Angle-Angle or AA similarity postulate,

When triangle ABC reflect onto EDC, then triangle will be congruent and equal.  

Implies that ΔABC ≅ ΔDEC.

Hence, option (B) is the correct answer.

Answer:

A) -2x + y = 3

Step-by-step explanation:

The equation of the line that is perpendicular to the given line and passes through its y-intercept is -2x + y = 3.

We are given that;

The equation= 2x + 4y - 12

Now,

The given line is 2x + 4y - 12 = 0.

To find the slope of a line perpendicular to this line, we need to find the slope of the given line first.

Rewrite the equation in slope-intercept form which is given by:

y = mx + b

where m is the slope and b is the y-intercept.

2x + 4y - 12 = 0

4y = -2x + 12

y = (-1/2)x + 3

Hence, the slope of the given line is -1/2.

The slope of a line perpendicular to this line is the negative reciprocal of this slope which is given by:

[tex]m(perpendicular)[/tex] = -1/m = -1/(-1/2) = 2

To find an equation of a line that passes through the y-intercept of the given line and has a slope of 2.

The y-intercept of the given line can be found by setting x = 0:

2(0) + 4y - 12 = 0

y = 3

Hence, the y-intercept of the given line is 3.

The equation of a line with a slope of 2 and passing through (0,3) can be found using point-slope form which is given by:

y - y1 = m(x - x1)

where (x1,y1) = (0,3) and m = 2.

Substituting these values we get:

y - 3 = 2(x - 0)

y - 3 = 2x

y = 2x + 3

Therefore, by the equation answer will be -2x + y = 3.

The equation in a point-slope form that  represents their distance from

home, y miles, after x hours, is y - 110 = 55(x - 2)

Step-by-step explanation:

The point-slope form of the linear equation is

[tex]y-y_{1}=m(x-x_{1})[/tex] , where

m is the slope of the line (average)

[tex](x_{1},y_{1})[/tex] is a point on the line

→ The family is driving home  from vacation at an average speed

    of 55 miles per hour

∴ m = 55

→ After 2 hours they  are 110 miles from home

∵ x is the number of hours

∵ y is the distance in miles after x hours

∴ [tex]x_{1}[/tex] = 2

∴ [tex]y_{1}[/tex] = 110

→ Substitute these values in the form of the equation above

∴ y - 110 = 55(x - 2)

The equation in a point-slope form that  represents their distance from

home, y miles, after x hours is y - 110 = 55(x - 2)

x>10

Answer:

y=-0.2x+5. Correct choice: A)

Step-by-step explanation:

Modeling With Equations

Let's call x the number of minutes and y the distance from home. The correct model should meet both conditions:

After 5 minutes, Ye is 4 miles from home. This is the ordered pair (5,4)

After 15 minutes, Ye is 2 miles from home. This is the ordered pair (15,2)

A) y=-0.2x+5. Testing the first point (5,4): y=-0.2*5+5=4. Correct

Testing the second point (15,2): y=-0.2*15+5=2. Correct

This is the correct choice.

B) y=11/7x-27/7. Testing the first point: (5,4) y=11/7*5-27/7=4. Correct

Testing the second point (15,2). y=11/7*15-27/7=138/7. Incorrect

Incorrect choice.

C) This equation is equal to the choice B), thus this one is incorrect.

D) y=5x-0.2. The first point (5,4) yields to:

4=5*5-0.2=24.8 Incorrect.

Answer:

225 wpm

Step-by-step explanation:

Ok, I'm gonna solve it as I type this:

So you know that she types 27k words in two hours so you can divide it by 2 to get the words per hour. 27000 divided by 2 is equal to 13500 or also 13.5k.

Now you know the hours, you can divide that by 60 to get the words per minute since there are 60 words per hour.

You get 225 words. (That is a very fast speed lol I do 140)

So 225 words per minute.
