10/15 as a % to 2 decimal places

Answer:

False

Step-by-step explanation:

if x=4 the answer would not be -9

x+51 would add up to 55

so it would be : 4+51=55

now if we wanted the answer to be -9 , x would have to be different

-60+51=-9

but in this case x is no -60, it's 4, so no this statement is false.

Answer:

59x - 5

Step-by-step

8x^2-5x+9 - (-9x) -7−9x−7

64x - 5x + 9 - 7 - 9x - 7

59x + 9 - 14

59x - 5

Answer:

the answer is D, -8< X <2

Answer:

p <= 12 and p >= -12

Step-by-step explanation:

The absolute value of p means that p is less than 12. Then, -p must be greater than -12

p <= 12 and p >= -12

-1/5

Step-by-step explanation:

subtract -2/5with -3/5and you will get -1/5

Answer:

x = -1

Step-by-step explanation:

When an exponent is negative, you have to move it to the denominator (or to the numerator if it's already on the denominator). Since the answer is [tex]\frac{1}{2}[/tex], you know that the 2 has been raised to the power of 1 (any number to the power of 1 is the same number), so you just make it negative. Hope that helps!

Answer:

x= -3

Step-by-step explanation:

−2(8x−1)=5(1−3x)

Step 1: Simplify both sides of the equation.

−2(8x−1)=5(1−3x)

(−2)(8x)+(−2)(−1)=(5)(1)+(5)(−3x)(Distribute)

−16x+2=5+−15x

−16x+2=−15x+5

Step 2: Add 15x to both sides.

−16x+2+15x=−15x+5+15x

−x+2=5

Step 3: Subtract 2 from both sides.

−x+2−2=5−2

−x=3

Step 4: Divide both sides by -1.

Step-by-step explanation:

Answer:

John: 223 words

Joseph: 446 words

Step-by-step explanation:

Given that,

Series 1: 3, 5.5, 8..... and series 2: 33/2, 57/2, 81/2.

To find,

The value of n.

Solution,

Let n is the no of terms in both the series.

For 3, 5.5, 8

First term, a = 3 and common difference d = 2.5

Sum of n terms of a series is given by :

[tex]S=\dfrac{n}{2}(2a+(n-1)d)[/tex]

So,

[tex]S=\dfrac{n}{2}(2\times 3+(n-1)2.5)\\\\S=\dfrac{n}{2}(6+2.5(n-1))\ ....(1)[/tex]

For 33/2, 57/2, 81/2

First term, a = 33/2 and common difference, d = 12

nth term of a series is given by :

[tex]a_n=a+(n-1)d[/tex]

For 2nd terms,

[tex]a_2=\dfrac{33}{2}+(2-1)\times 12\ ....(2)[/tex]

According to question, sum of the first n terms of the arithmetical progression 3, 5.5, 8. .... is equal to the 2nth term of the arithmetic  progression 33/2, 57/2, 81/2

From equation (1) and (2) :

[tex]\dfrac{n}{2}(6+2.5(n-1))=\dfrac{33}{2}+ 12\\\\\dfrac{n}{2}(6+2.5(n-1))=\dfrac{57}{2}\\\\n(6+2.5(n-1))=57\\\\6n+2.5n^2-2.5n-57=0\\\\2.5n^2+2.5n-57=0\\\\\text{On solving the above quadratic equation, we get the value of x as follows :}\\\\x=4.126,-5.526[/tex]

Neglecting the negative value, we get the value of n = 4.126

or

n = 4

Hence, the value of n is 4.

Answer:

Step-by-step explanation:

Time for first race 57.9seconds

x=time for first half of race

x-4.7=second half of race

Equations is

x + (x-4.7)=57.9

2x-4.7=57.9

2x=57.9+4.7

2x=62.6

x=31.3

Check answer

31.3 + (31.3-4.7)=57.9

31.3 +26.6=57.9

57.9=57.9

Answer:

x = [tex]\frac{17}{14}[/tex]

Step-by-step explanation:

simplify both sides of the equation

-9x + 10 - 5x = - 7

-9x + 10 + - 5x = -7

(-9x + -5x) + (10) = -7 (combine like terms)

-14x + 10 = -7

subtract 10 from both sides

-14x + 10 - 10 = -7 - 10

-14x = -17

divide both sides by -14

[tex]\frac{-14x}{-14}[/tex] = [tex]\frac{-17}{-14}[/tex]

x = [tex]\frac{17}{14}[/tex]

Answer:

The required equation is y = 3x + 17. Correct: B)

Explanation:

Equation of a line

A line can be represented by an equation of the form

y=mx+b

Where x is the independent variable, m is the slope of the line, m is the y-intercept and y is the dependent variable.

We are given the equation of a line as (corrected)

y=-1/3x+2

Note the slope of this line is m1=-1/3

We are asked to find the equation of another line that is perpendicular to the one above. Two lines are perpendicular if their slopes comply with the following condition:

[tex]m_1*m_2=-1[/tex]

Since we have m1, find m2:

[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]

[tex]\displaystyle m_2=-\frac{1}{-\frac{1}{3}}=3[/tex]

This means the slope of the required line is 3. We only have to test the options to find which one of us contains the point (-5,2):

A) The slope of this line is 3, so we test the point (-5,2)

2=3(-5)+13=-15+13=-2

Since 2 is different from -2, this option is not correct

B) The slope of this line is 3, so we test the point (-5,2)

2=3(-5)+17=-15+17=2

Since equality stands, this is the correct option

C) The slope of this line is -3, it cannot be the required line. This option is not correct

D) The slope of this line is -3, it cannot be the required line. This option is not correct
