Answer:

h=-18

Step-by-step explanation:

Here you go mate

Step 1

55 – -26h = -413  Question

Step 2

55 – -26h = -413

26h+55=-413

Step 3

26h+55=-413  Subtract 55

26h=-468

Step 4

26h=-468  Divide sides by 26

Answer

-18

Answer:

Whole numbers are 1, 2, 3, 4, and so on. Integers can be whole numbers or they can be whole numbers with a negative sign in front of them. Individuals often refer to integers as the positive and negative numbers.

Step-by-step explanation:

I usually stick to this: Name Numbers Examples Whole Numbers { 0, 1, 2, 3, 4, ... } 0, 27, 398, 2345 Counting Numbers { 1, 2, 3, 4, ... } 1, 18, 27, 2061 Integers { ... −4, −3, −2, −1, 0, 1, 2, 3, 4, ... ... −15, 0, 27, 1102 soo i didnt give u the answer but i gave u examples and my strategy

Answer:

130z-3

Step-by-step explanation:

Break down the equation:

(9[tex]z^{2}[/tex]-4)=

9z * 9z= 81z

You can't subtract 4, so I left it at (81z- 4)

(7[tex]z^{2}[/tex]+ 1)=

7z * 7z= 49z

You can't add 1, so I left it at (49z+ 1)

Then Solve:

You can add 81z and 49z.

81z+49z= 130z

-4+1= -3

Hope this helps!

Answer:

x=8 y=4

Step-by-step explanation:

Im assuming that you are learning standard form and to solve for a variable you set the other value to 0.

3x+6(0)=24

3x=24

divide by 3

x=8

Answer:

I love algebra anyways

the ans is x=8−2y its in the picture and so is the steps

(hope that helped can i plz have brainlist it will make my day :D hehe)

Step-by-step explanation:

Answer:

1. 3600 x 25 ÷100 =900

there fore the discount price is p900

3. it means if you add to integers you get 143

so x +x+1=143

2x +1=143

2x+1-1=143_1

2x=142

2x/2 =142/2

x=71

x+1=71+1=72

Answer:

Step-by-step explanation:

Answer:

w = -z(-w) + 3(-w)

Step-by-step explanation:

z = w + 3 | Given

-w + z = 3 | Subtract w from both sides.

-w = -z + 3 | Subtract z from both sides

w = -z(-w) + 3(-w) | Multiply -w on both sides.

Answer:

It is not possible for Alice to score an average of 75% because what she needs to score in the fifth exam exceeds the maximum possible score.

Step-by-step explanation:

She scored an average 68% in all 4 exams.

This means; (68% + 68% + 68% + 68%)/4

Now, a fifth exam is added and we want to know if her average can now be 75%.

Thus, let the score in the 5th exam be x and we now have;

(68% + 68% + 68% + 68% + x)/5 = 75%

Multiply both sides by 5 to get;

(68% + 68% + 68% + 68% + x) = 375%

272% + x = 375%

x = 375% - 272%

x = 103%

The maximum score is 100% and therefore it is impossible for her to score 103%. Therefore it is not possible for Alice to score an average of 75%

Answer:

x = 12

Step-by-step explanation:

Given that,

GCF of HCF of two numbers = 3

LCM of numbers = 180

First number = 45

Let another number be x.

So,

HCF×LCM = first number × second number

[tex]x=\dfrac{3\times 180}{45}\\\\x=12[/tex]

So, the other number is 12.

Answer:

1162.08

Step-by-step explanation:

zahid is paid 774.72 for 36 hrs so,

he worked 43 hrs,

so no. of hours ot: 43-36

7 hrs

now we will find the half of 774.72

387.36

now add 774.72+387.36

1162.08

so that was his earning

Answer:

the area is 110. the formula for a trapezoid is A= a+b/2 × h.

A= a+b/2 ×h= A= 9+13/2×10=110

Use this and explain yourself

Answer:

The HCF of [tex]a=2^1 \cdot 3^4 \cdot 5^1[/tex] and [tex]b = 2^3 \cdot 3^2 \cdot 5^2[/tex] is [tex]90[/tex].

Step-by-step explanation:

To calculate the HCF of two numbers given their prime factorization, we take the lowest exponent of every prime when comparing the two numbers.

So the HCF of [tex]a=2^1 \cdot 3^4 \cdot 5^1[/tex] and [tex]b = 2^3 \cdot 3^2 \cdot 5^2[/tex] is [tex]2^1 \cdot 3^2 \cdot 5^1 = 90[/tex].

Answer:

97.2m/s

Step-by-step explanation:

1 km = 1,000 m

1 h = 3,600s

so

350km/h = 350*1000/3600

= 97.222 m/s

Answer:

Irrational

Step-by-step explanation:

The square root of 3 is not a perfect square, therefore it is irrational. Another way you could see if it is rational is if it can be put in a fraction, if it can't, then it is irrational.

Answer:

Slope is 2/1x

Y- intercept = 12

Equation is y = 2x + 12

Answer:

The answer is

[tex]y = \frac{1}{3} x - 1[/tex]

Step-by-step explanation:

Let The equation is

[tex]y = mx + c[/tex]

Since the straight line intersects with Y axis at - 1

Then x equal to zero

Since m=1/3

Then

[tex]y = \frac{1}{3} x + c \\ when \: y = - \: \: and \: x = 0 \\ then \: c = - 1 \\ y = \frac{1}{3} x - 1[/tex]

Answer:

4. [tex]4x^{2} +2x-2[/tex]

Step-by-step explanation:

To add these two equations together, you have to combine like terms.  

1. [tex]x^{2} +3x^{2} = 4x^{2}[/tex]

2. [tex](-3x)+5x = 2x[/tex]

3. 7 - 9 = -2

Then you just combine all of these terms together into one equation and you have your answer.

Hope this helped!
