Answer:

-5 ≠ 23

Step-by-step explanation:

5(3−4)=8+15

5(-1) = 8 + 15

-5 = 23

-5 ≠ 23

Answer:

t = -4

Step-by-step explanation:

-6-9t+4=34

-9t=34+6-4

-9t=36

-t=36/9

-t = 4

t = -4

Answer:

t = -4

Step-by-step explanation:

-6-9t+4=34

Combine like terms

-9t -2 = 34

Add 2 to each side

-9t -2+2 = 34+2

-9t = 36

Divide by -9

-9t/-9 = 36/-9

t = -4

Answer:

27

Step-by-step explanation:

Number of member of staff that drank tee = total number of member of staff - number that drank coffee - number that drank both tea and coffee

100 - 48 - 25 = 27 members of staff

Answer:

use the slope formula to find the slope of a line given the coordinates of two points on the line and the slope formula is m=( y2- y1)/ (x2 - x1) or the change in the y values over the change in x values.The coordinates of the point represent x1 and y1. The coordinates of the second points are x2, y2.

Step-by-step explanation:

That appears to be approximately 45 degrees, so to the nearest 10, I would put that at about a 50 degree angle.

Answer:

x=3

Step-by-step explanation:

5(2)^x=40

Divide each side by 5

5 /5 *(2)^x=40/5

2^x = 8

Rewriting 8 as 2^3

2^x = 2^3

The bases are the same so the exponents are the same

x=3

Answer:

x = log(40)

Step-by-step explanation:

[tex]5(2)^{x} =40[/tex]

[tex]10^{x} =40[/tex]

[tex]10^{x} =40[/tex]

x = log(40)

Answer:

it think it is 26

Step-by-step explanation:

= x = 6

Answer:

I think it will be combined and simplified

Answer:

Simplified/combined

Explanation:

In order to simplify an algebraic expression you need to combine all of the like terms which have the same variables and powers.

Answer:

If a line is parallel with Another...

They will have the same Gradient or equal Gradient (m)

So for two parallel lines

m=m'

So the gradient of the second or other line would be Same

Now

y= -3x + 10

comparing with

y= mx + c

m = -3

So the other line would have the same gradient.

from the options provided in the comment section...

y= -3x + 12

Is your Most probable answer cos it has the same gradient

Answer:

10, 100, 1,000, 10,000, 100,000

If you are adding one zero in the end for every number, then 100,000 will be your next number

Answer:

31

Step-by-step explanation:

y=2x^2 - 2x + 7

Let x= -3

y=2(-3)^2 - 2(-3) + 7

 =2 (9) +6 +7

 = 18 +6+7

 = 31

[tex]\tt{y = 2 {x}^{2} } - 2x + 7 \: ,when \: x \: = \: - 3[/tex]

[tex]\quad \quad \quad \quad \tt{y = 2 {x}^{2} } - 2x + 7[/tex]

[tex]\quad \quad \quad \quad \tt{y = 2 {( - 3)}^{2} } - 2( - 3)+ 7[/tex]

[tex]\quad \quad \quad \quad \tt{y = 2(9) +6 + 7}[/tex]

[tex]\quad \quad \quad \quad \tt{y = 18 +6 + 7}[/tex]

[tex]\quad \quad \quad \quad \tt{y = 24 + 7}[/tex]

[tex]\quad \quad \quad \quad \tt{y = 31}[/tex]

[tex]\quad \quad \quad \quad \boxed{\tt{\color{green}y = 31}}[/tex]

Answer:

10

Step-by-step explanation:

d = √(x2  -x1)² + (y2 - y1)²

√(-6 - 0)² + [1 - (-7)]²

√(-6)² + (8)²

√(36) + (64)

√100

= 10

Answer:

Probability that he chooses blue next is 4/7.

Step-by-step explanation:

In total, there are 35 marbles, since 20 + 15 = 35

There are 20 blue marbles out of the 35 marbles, so that's 20/35.

20/35 simplified is 4/7.

Answer:

x < -1/2

Step-by-step explanation:

x - 8 > 5x

-8 > 5x -x

-8 > 4x

Divide through by 8

-1/2 > x or x < -1/2.

That is ofcourse if I interpreted the first part correctly.

Step-by-step explanation:

Angle C: 50 degrees

Angle E: 55 degrees

Angle D: 50 degrees

Angle A: 125 degrees

Angle B: 75 degrees

Step-by-step explanation:

Everything Shoes:

E * 0.8 = 115

E = 115/.8 = $143.75

~~~~~~~~~~~~~~~~

B * 0.15 = 7

B = 7/.15

B = $46.67

Answer:

8/12 = x/14

Not sure if this is a proportion but this is how I would solve it.
