Answer:

5

Step-by-step explanation:

this can be solved using simultaneous equation

2a + 3b = 19  equation 1

1a + 4b = 17    equation 2

Multiply equation 2 by 2

2a + 8b = 34  equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Answer:

B

Step-by-step explanation:

So wiggly, remember that slope is change in y/change in x, or in simpler terms, y/x. Thinking of this, y/x must simplyfy to -3. Or, you can think of it as -3/1.

So know that we have rewrote this as a slope of -3/1, lets use it. Where do we start? Well, we must start at point A, which is at 2 x and 7 y.

Now, going to the  RIGHT(+1x) and going DOWN(-3y) we will go from 2x and 7y to 3x and 4y.

Are we on a point yet? Nope, lets do this again.

Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 13x and 4y to 4x and 1y.

Are we on a point yet? Still no, lets try this one more time.

Now going to RIGHT again(+1x) and going DOWN again(-3y) we will go from 4x and 1y to 5x and -2y.

Are we on a point? YUP. We cna see that point B is at 5x and -2y.

Hope you get it right ;)

Answer:

35 degrees and 50 degrees

Step-by-step explanation:

The sum of all the angles in a triangle must be 180 degrees. So 180 - 95 = 85 leftover for the other two angles. Since we have a ratio of 7:10, we can add that up to get 17 total pieces of that 85-degree angle. 85 / 17 = 5, so each piece is 5 degrees. Therefore, the other two angles are 7*5 = 35 degrees and 10*5 = 50 degrees.

Answer:

3. D) 26, 7, 31

4. B) 6, 34, 27

Step-by-step explanation:

Both #3 and #4 use the same strategy: the two shorter sides' sum has to be greater than the longer side.

#3:

2 + 8 is 10, which is less than 13. So A wouldn't form a triangle.

12 + 22 is 34, which is the length of the longer side. So B wouldn't form a triangle either.

14 + 18 is 32, which is less than 40. So C wouldn't form a triangle.

7 + 26 is 33, which is greater than 31. So D would form a triangle.

D. 26, 7, and 31 are the only lengths of the ones shown that form a triangle.

#4:

17 + 18 is 35, which is greater than 19. So A would form a triangle.

11 + 22 is 33, which is greater than 25. So C would also form a triangle.

5 + 18 is 23, which is greater than 20. So D would form a triangle.

6 + 27 is 33, which is less than 34. So B wouldn't form a triangle.

B. 6, 34, and 27 are the only lengths of the ones shown that don't form a triangle.

Answer:

Step-by-step explanation:

Ok so for question one we use the Pythagorean theorem, which is a^2+b^2=c^2

a is the shortest leg, b is the leg that is not the hypotenuse. and c is the hypotenuse which is the opposite leg to the right angle.

Question 1: a=9,b=12,c=x

(9)^2+(12)^2=(x)^2

81+144=(x)^2

225=(x)^2

x=15

Question 2: a=10,b=24,c=x

(10)^2+(24)^2=(x)^2

100+576=(x)^2

676=(x)^2

x=26

Question 3: a=3,b=7,c=x

(3)^2+(7)^2=(x)^2

9+49=(x)^2

58=(x)^2

x=root58, or 7.615773

Question 4: a=6,b=x, c=10

(6)^2+(x)^2=(10)^2

36+(x)^2=100

Subtract 36 from both sides

(x)^2=64

x=8

Question 5: a=6,b=x, c=24

(6)^2+(x)^2=(24)^2

36+(x)^2=576

Subtract 36 from both sides

(x)^2=540

x=6root15, or 23.2379

Question 6: a=1, b=1, c=x

(1)^2+(1)^2=(x)^2

1+1=(x)^2

2=(x)^2

x=root2, or 1.414213562

Question 7: a=8, b=x, c=21

(8)^2+(x)^2=(21)^2

64+(x)^2=441

Subtract 64 from both sides

(x)^2=377

x=root377, or 19.41648784

Question 8: a=24, b=x, c=30

(24)^2+(x)^2=(30)^2

576+(x)^2=900

Subtract 576 from both sides

(x)^2=324

x=18

Question 9: a=5,b=9, c=x

(5)^2+(9)^2=(x)^2

25+81=(x)^2

106=(x)^2

x=root106, or 10.29563014

Question 9 Part B: a=3, b=5, c=y

(3)^2+(5)^2=(y)^2

9+25=(y)^2

34=(y)^2

root34, or 5.830951895=y

Answer:

$300

Step-by-step explanation:

$400 is 100% of the price

25% is  a quarter of 100%

A quarter of 400 is 100 so the discount was    $100

400-100 =300

Answer:

C. 3n(6) + (6 – 2)

Step-by-step explanation:

C. 3n(6) + (6 – 2) has a coefficients, a product and a sum

Coefficients = 3

3 is the coefficients of n

Product means multiplication

3n(6) = product of 3n and 6

Sum means addition(+)

3n(6) + (6 – 2) = the addition of 3n(6) and (6 - 2)

3n(6) + (6 – 2)

= 18n + (4)

= 18n + 4

Answer:

There are 30 gifts altogether.

Answer:

s = 23 - e

Step-by-step explanation:

In this expression, s is equal to the amount of extra credit Sofia earns. She earns e less points than the 23 points Zeke earns.

So, s (Sofia's points) = 23 (Zeke's points) - e (the difference in points).

The expression is s = 23 - e.

Good luck ^^

Answer:

37

Step-by-step explanation:

x = 1st number

y = 2st number

z = 3rd number

x + y + z = 235

y = x + 15

z = 8x

x + x + 15 + 8x = 235

10x = 220

x = 22

y = 37

z = 176

The second number is 37.

Given that,

Based on the above information, the calculation is as follows:

x + y + z = 235  

y = x + 15  

z = 8x

Now  

x + x + 15 + 8x = 235

10x = 220

x = 22

So,

y = 22 + 15

= 37

Answer:

y = -2x + 11

Step-by-step explanation:

If you already have the slope, all you need to do is find the y-intercept.

y = -2x + b

1 = -2(5) + b

1 = -10 + b

11 = b

The equation is y = -2x + 11
