Answer:

The answer would be 1.5kg.

Step-by-step explanation:

2/.25=.50

.50x4=2

100%-25%=75%

75%=1.5kg

Answer:

b=-3

Step-by-step explanation:

distribute 3(b-2) and you get 3b-6.

-3+4b=3b-6

add 3 on both sides.

4b=3b-3

-3b on both sides

b=-3

Complete question :

A dolphin starts at an elevation of -16 3/4 feet. He kicks 5 times and increases his elevation by the same amount for each kick. He is now at an elevation of -5 1/4 feet. Which equation can be used to find x, the number of feet the dolphin traveled with each kick?

Answer:

2 3/10 feets

Step-by-step explanation:

Initial elevation = - 16 3/4 feets

Number of kicks = 5

Increase in elevation is the same for each kick

Final elevation = - 5 1/4 feets

Number of feets, x, dolphin travels per kick ;

Total elevation achieved after 5 kicks : ; change in elevation

Final elevation - initial elevation

16 3/4 - 5 1/4

67 /4 - 21/4

(67 - 21) / 4

= 46/4

Since change in elevation per kick is the same;

Number of feets traveled per kivk is ;

x = 46/4 ÷ 5/1

x = 46/4 * 1/5

x = (46*1) / (4*5)

x = 46/20

x = 2 6/20 = 2 3/10

Dolphin travels 2 3/10 feets per kick

Answer:

4 is greater

Step-by-step explanation:

A negative divided by a positive = a negative.

No matter what y is, it will be a negative number.

Meaning, 4 a positive number, will be greater no matter what y is

Answer:

angle p+30=180=

=180-30=150

angle Q+55=180

=180-55=125

angle R+95=180

=180-95=85

Step-by-step explanation:

[tex]log \frac{a}{b} = loga - logb[/tex]

logx - log3 = log(x-2)

[tex] log( \frac{x}{3} ) = log(x - 2)[/tex]

[tex] \frac{x}{3} = x - 2[/tex]

x = 3(x - 2)

x = .......

Answer is 154

Step-by-step explanation:

Answer:

sine 23 = x/21

Multiply both sides by 21

21 x sine 23 = x

Now, use a calculator and find the answer of the 21 times the sine of 23:

x = -17.7706284876

Answer:To create an equivalent expression, you simply need to move the base and exponent to the other side of the fraction line and change the exponent to positive: 1/(24)

Answer:

x=15, y=12, z=20

Step-by-step explanation:

y is the geometric mean of the two segments it divides.

9 · 16 = y^2

y=12

Use the pythagorean theorem to find x and z.

16^2 + 12^2 = z^2

z^2 = 400

z=20

9^2 + 12^2 = x^2

x^2 = 225

x=15

Answer:

F(x)= 3x-4

Step-by-step explanation:

To find the slope use the formula y2-y1  

                                                          x2-x1

(2,2)

(0,-4)

-4-2 = -6   = 3x

0-2      -2

Step-by-step explanation:

6x - x² = k

=> x² - 6x + k = 0,

For there to be at least 1 real solution,

The discriminant b² - 4ac must be at least 0.

We have (-6)² - 4(1)(k) >= 0.

Therefore 36 - 4k >= 0, k <= 9.

Hence the largest value of k is 9.

Answer:

9

Step-by-step explanation:

Rearranging, this is the equation x^2 - 6x  = -k. Completing the square, we add 9 to both sides, and x^2 - 6x + 9 = 9 - k. Factoring the left side, we have (x - 3)^2 = 9 - k. In order for this equation to have at least one real solution, the right-hand side must be nonnegative. Thus, we have 9 - k [tex]\geq[/tex] 0 and k [tex]\leq[/tex] 9. Thus, the largest possible value of k is 9.

Answer:

y = -5x + 4

Step-by-step explanation:

Solve for y

10x + 2y = 8

2y = -10x + 8

y = (-10x)/2 + 8/2

y = -5x + 4

Answer:

Step-by-step explanation:

Kendra has a goal to walk 10 miles in one week.

She has already walked 2 miles on Monday and 3 miles on Tuesday. This means that she has already walked:

= 2 + 3

= 5 miles

If she wants to walk a total of 10 miles with w being the remaining miles, the expressions will therefore be:

w + 5 = 10

or;

10 - 5 = w

Answer:

x = 1

Step-by-step explanation:

[tex]\frac{4x-1}{2}+\frac{3x+4}{3}= \frac{23}{6}[/tex]

[tex]\frac{3(4x-1)}{6}+\frac{2(3x+4)}{6}= \frac{23}{6}[/tex]

[tex]\frac{12x-3+6x+8}{6}=\frac{23}{6}[/tex]

18x + 5 = 23

18x = 23 - 5

18x = 18

x = 1

Therefore, x = 1 is the solution of the given expression.

Answer:

x=5 and y=-2

Step-by-step explanation:

3x+5y=5

-(7x+5y=25)

y= -2

Answer:

y = ~-0.43x + 1.43

Step-by-step explanation:

You are solving for Y.

3x + 7y = 10

7y = -3x + 10 ^ Subtraction Property of Equality

y = ~-0.43x + 1.43 ^ Division Property of Equality
