Find the smallest integer that satisfies the inequalities
sammy [17]

Answer:

a. x> 23 /3

b: x< 13/5

Step-by-step explanation:

A: Step 1: Subtract x from both sides.

4x−15−x>x+8−x

3x−15>8

Step 2: Add 15 to both sides.

3x−15+15>8+15

3x>23

Step 3: Divide both sides by 3.

<u>x> 23/3</u>

B: Step 1: Subtract 7x from both sides.

2x+13−7x>7x−7x

−5x+13>0

Step 2: Subtract 13 from both sides.

−5x+13−13>0−13

−5x>−13

Step 3: Divide both sides by -5.

Answer:  x< 13/5

What is the solution of
loris [4]

Answer:

x = -1/2

Step-by-step explanation:

1-3x = x+3

Add 3x to each side

1-3x+3x = x+3x+3

1 = 4x+3

Subtract 3 from each side

1-3 = 4x+3-3

-2 = 4x

Divide each side by 4

-2/4 = 4x/4

-1/2 =x

Help asap plsss!!!!!!!!!!!
Harman [31]
To find x we are gonna use the cosine formula.

Cos 0 = adj/hyp

0 represents theta

Cos 0 = adj/hyp

Cos 0 = 25/40

Convert 25/40 to decimal from

25/40 = 0.625

On a scientific calculator press the key “2nd F” or “Shift” then “cos”(which would give cos inverse) then type 0.625 equal.


Cos-1 0 0.625

= 51.31 degrees

x is therefore 51.3 degrees to the nearest tenth

How many solutions will each system of linear equations have? Match the systems with the correct number of
JulsSmile [24]

Answer:

Step-by-step explanation:

Given that,

y = x + 6 equation 1

3x - 3y = -18.  Equation 2

Substitute equation 1 into equation 2

3x-3(x+6) = -18

3x - 3x - 18 = -18

-18 = -18

Therefore, it has no solution. Check attachment for echelon matrix solution

B. y = -2x + 5 equation 1

2x + y = -7.  Equation 2

Substitute equation 1 into 2

2x -2x + 5 = -7

5 = -7

Since the equation is not balance, then, it has infinite numbers of solution.

C. y = -4x + 11.  Equation 1

6x + y = 11.   Equation 2

Substitute equation 1 into 2

6x - 4x + 11 = 11

2x = 11 - 11

2x = 0

x = 0

Also, y = -4x + 11

y = 0 + 11 = 11

Then, this has a unique solution I.e. one solution.

ted says that 3/10 multiplied by 100 equals 300000 is he Correct you the place value chart to explain your answer
kolezko [41]
Ted is incorrect because 3/10 is the same as .30 which is then multiplied by 100 and given the product of 30.
.3×100=30
