Answer:

Step-by-step explanation:

4d + 7e = 68

-4d - 6e = -72

e = -4

4d  + 7(-4) = 68

4d - 28 = 68

4d = 96

d = 24

Answer:

let (8,3) be (x1,y1)

(2,7) be (x2,y2)

using distance formula

√[(x2-x1)²+(y2-y1)²]

√(2-8)²+(7-3)²

√(36+16)

√52

Answer:

Step-by-step explanation:

Points A, B, and C are collinear and point B is between A and C then

AB + BC = AC

2x - 4 + 1 = x + 2

2x - 3 = x + 2

   +3          +3

2x  =  x + 5

  -x     -x

  x  =  5

AB = 2x - 4 = 2×5 - 4 = 10 - 4 = 6

AC = AB +BC = 6 + 1 = 7

Answer: The answer is B

Answer:

y = -5x + 7

Step-by-step explanation:

Graph has a slope of -5, which is the gradient

y = -5x + c

To find c you have to sub in the point (2, -3)

-3 = -5(2) + c

-3 + 10 = c

c = 7

Hence equation is:

y = -5x + 7

Step-by-step explanation:

Answer:

x = 56

Step-by-step explanation:

Step 1: Write out equation

x + 20 + x + 48 = 180

Step 2: Combine like terms (x)

2x + 20 + 48 = 180

Step 3: Combine like terms (constants)

2x + 68 = 180

Step 4: Subtract 68 on both sides

2x = 112

Step 5: Divide both sides by 2

x = 56

Answer: Amy will not have one dollar left over , but she will have to add an extra dollar to buy all that stuff.

Step-by-step explanation:

First find  the cost of the items she want to buy in total.

So she wants to buy 3 pound  of lemons at two dollars per pound that will cost her $6.

Seven frozen dinners for three dollars each will cost her  $21.

The box of rice will cost her  $4.

Add the total cost together.

21 + 4 + 6 = 31  

This means she will have to spend $31 in total and that is beyond her budget which is $30  dollars. This also means that Amy will not have one dollar left over but she will need to add one dollar.

Answer:

Amy won't have 1 dollar left, she will actually need 1 dollar because all of that would be 31 dollars.

Step-by-step explanation:

3 pounds of lemons= $6

1 box of rice= $4

7 frozen diners= $21

6+4=10

10+21=31

Step-by-step explanation:

78 + 119 + 105 + (180 - x) = 360

482 - x = 360

482 - 360 = x

122 = x

x = 122°

Answer:

it is trapezium and all angles value is 360 degree and three angles values are given then let unknown angle be y and add three angles then subtract value from 360 degree then add the value with x and subtract that value from 180 degree

What is mean?

Arithmetic Mean represents a number that is obtained by dividing the sum of the values of a data set by the total number of values

What is statistic?

A statistic (singular) or sample statistic is any quantity computed from values in a sample which is considered for a statistical purpose.

The mean takes into account the whole spread of the data among the various statistic and is helpful in comparing data.

Answer:

13

Step-by-step explanation:

time=distance÷speed

650÷50=13

The time taken by the gorilla to hit the ground will be 13 seconds.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Given that Thomas the giant gorilla climbed to the top of the building 650 feet tall. He broke loose a statue and threw it down with an initial velocity of 50 feet per second.

The time taken by the gorilla will be calculated by the formula of speed below,

Speed = Distance / Time

Time = Distance / Speed
Time = 650 / 50

Time = 13 seconds

4r-7

hope this helped :)

Answer:

-7 + 4r

Step-by-step explanation:

You need to combine like terms for this problem. All the basic numbers(without the r) are added together. -14 + 7 = -7. Then the numbers with the r's are added together. -9r + 13r = 4r. This comes out to -7 + 4r

HK consists of two part, HJ and JK

HK = HJ + JK

We know that:

HK = 12.2ft

JK = 3.1ft

HJ = ?

Let's plug our values into the equation above.

12.2ft = HJ + 3.1ft

Subtract 3.1ft from both sides.

9.1ft = HJ

Answer:

1. a

2. b

3. c

Step-by-step explanation:

1. a

For this first graph, we know that it matches a because of the domain. A tells us that the x≠-1. We know this because of the denominator.

(x+1)(x+1)=0          subtract both sides by 1]

x=-1

Therefore, a matches graph 1.

------------------------------------------------------------------------------------------------------

2. b

For graph 2, we can see that the graph is under the x-axis, meaning it is all negative. The only option that gives us a negative point is b. You can tell by the negative sign in front of the square root.

Therefore, b matches graph 2.

------------------------------------------------------------------------------------------------------

3. c

For graph 3, we see that everything is above the x-axis, meaning the graph is always positive. The option that fits this is c. In c, there are absolute values. Absolute values tell us that the answer is always going to be positive.

Therefore, c matches graph 3.

Step-by-step explanation:

This graph has a vertical asymptote at x=0, this means that it is not continues at x=0. However as the Limit, x approches 0, it is very close to 57.296.

Answer:

x= 3, y=0, z= 1

Step-by-step explanation:

Let's label the 3 given equations first.

2x +3y +4z= 10 -----(1)

3x +2y -4z= 5 -----(2)

x +4y +2z= 5 -----(3)

(1) +(2):

This is to eliminate the z term.

2x +3y +4z +3x +2y -4z= 10 +5

5x +5y= 15

Divide by 5 on both sides:

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

(3) ×2:

2x +8y +4z= 10 -----(5)

(2) +(5):

This is to eliminate z term.

3x +2y -4z + 2x +8y +4z= 5 +10

5x +10y= 15

Divide by 5 throughout.

x +2y= 3 -----(6)

(6) -(4):

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

x +2y -x -y= 0

y= 0

subst. y=0 into (4):

x +0= 3

x= 3

subst. x=3, y=0 into (3):

3 +4(0) +2z= 5

3 +2z= 5

2z= 5 -3

2z= 2

z= 2÷2

z= 1

Answer:

Step-by-step explanation:

4x - 9 = 9x - 34

-5x - 9 = -34

-5x = -25

x = 5

4(5) - 9 + 9(5) - 34

20 - 9 + 45 - 34

11 + 11 = 22

The value of CT such that J is the midpoint of CT will be 22.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given,

J is the midpoint of CT

CJ = JT

4x - 9 = 9x - 34

-9 + 34 = 9x - 4x

25 = 5x

x = 5

So CT = 2(CJ) = 2(4 x 5 - 9) = 22

Hence "The value of CT such that J is the midpoint of CT will be 22".
