Answer: 5b = 15

Step-by-step explanation:

5b + 2 = 17

     - 2     -2

5b = 15

The two steps are:

step 1  : 5b = 17 - 2

step 2 : b = 15/5

Given,

5b + 2= 17

Now,

The equation given two us is in linear form with one variable .

So,

Simplifying the equation,

5b + 2= 17

Take 2 from LHS to RHS

5b = 17 - 2

5b = 15

b = 15/5

b = 3

Thus the value of b is 3 .

Answer:The volcano has a height of nearly 22 km (13.6 mi or 72,000 ft) as measured by the Mars Orbiter Laser Altimeter (MOLA). Olympus Mons is about two and a half times Mount Everest's height above sea level.

Olympus Mons - Wikipedia

Step-by-step explanation:

Olympus Mons on Mars is the tallest mountain in the solar system, standing over 20 kilometers above its surroundings and nearly 30 kilometers above the lowest points on Mars.

The height of Olympus Mons, which is the tallest mountain in the solar system, located on Mars, is incredibly impressive in comparison to mountains on Earth. Olympus Mons towers more than 20 kilometers above its surroundings, reaching nearly 30 kilometers above the lowest elevation areas on Mars. When converted to more familiar units, this equals approximately 22 miles in height, a figure that dwarfs the height of Mount Everest, which stands at 29,029 feet or about 8.848 kilometers.

For this case we must solve the following equation:

[tex]\frac {2} {5} + p = \frac {4} {5} + \frac {3} {5}[/tex]

Since the denominators on the right side of the equation are equal, then we add the fractions:

[tex]\frac {2} {5} + p = \frac {4 + 3} {5}\\\frac {2} {5} + p = \frac {7} {5}[/tex]

We subtract [tex]\frac {2} {5}[/tex]on both sides of the equation:

[tex]p = \frac {7} {5} - \frac {2} {5}\\p = \frac {7-2} {5}\\p = \frac {5} {5}\\p = 1[/tex]

Thus, the value of p is 1.

Answer:

[tex]p = 1[/tex]

-2(-5x - 4) + 2x = 116

10x + 8 + 2x = 116

12x + 8 = 116

12x = 108

x = 9

Answer:r

Step-by-step explanation:

let x and y this numbers : x +y = -103 and x = y +59

so : y+59 +y = -103

2y +59 = -103

2y +59-59 = -103-59

2y = -162

y = -162/2

y = -81  but  x = y +59

so : x = -81+59

x = -22

The two numbers satisfying the given condition is -22 and -81.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have sum of two numbers is -103. One number is 59 less than the other.

Assume that the first number is [x]. Then, another number would be (x - 59).

We can write -

x + (x - 59) = - 103

2x - 59 = - 103

2x = - 103 + 59

2x = - 444

x = - 22

Another number would be -

x - 59 = - 22 - 59 = - 81

Therefore, the two numbers satisfying the given condition is -22 and -81.

Answer:

840,000 / 306,000 = 2.7450980392

So, Greenland is about 2 and 3/4 times larger than New Guinea.

Step-by-step explanation:

Greenland, the largest island in the world, is 534,000 square miles larger than New Guinea.

Greenland is 840,000 square miles and New Guinea is 306,000 square miles. To find out how much larger Greenland is than New Guinea, we subtract the area of New Guinea from the area of Greenland:

840,000 - 306,000 = 534,000 square miles

Therefore, Greenland is 534,000 square miles larger than New Guinea.

To determine how much larger Greenland is than New Guinea, one must subtract the size of New Guinea from the size of Greenland. Given that Greenland, the largest island in the world, is 840,000 square miles and New Guinea is 306,000 square miles, you would perform the following calculation:

840,000 - 306,000 = 534,000 square miles

Therefore, Greenland is 534,000 square miles larger than New Guinea.

Answer:

x = y + 8

Step-by-step explanation:

Given

y = x - 8 ( add 8 to both sides )

y + 8 = x

Final answer:

To make x the subject of the equation y = x - 8, simply add 8 to both sides of the equation to get x = y + 8, which is the rearranged equation.

Explanation:

To rearrange the equation y = x - 8 to make x the subject, you need to isolate x on one side of the equation. Here are the steps to do so:

Add 8 to both sides of the equation to get y + 8 = x.

Once you have done that, the equation is already solved for x, and the new equation with x as the subject is x = y + 8.

This process is common in algebra when solving linear equations or finding the equation of a line, similar to when you want to determine the line of best fit in a set of data points. For example, in the equation y = 9 + 3x, rearranging to solve for x would involve subtracting 9 from both sides and then dividing by 3.

2/3x=36

multiply by 3 both sides

x=54

The value of the number whose two thirds part is equal to the number 36 is number 54.

A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,

[tex]\dfrac{a}{b}[/tex]

Here (a) is the numerator and (b) is the denominator.

Two thirds of a number is 36. Let suppose the number is x. As it is given that the two third of this number x is equal to the 36.

Thus, we have to multiply the fraction 2/3 to x and equate it to 36.

[tex]x\times\dfrac{2}{3}=36\\x=\dfrac{36\times3}{2}\\x=54[/tex]

Step-by-step explanation:

given

[tex](1.5 \times {10}^{4} )(8 \times {10}^{8} )[/tex]

in order to make multiplication easier we need to change the 1.5 into a whole number form.

thus

[tex](15 \times {10}^{ - 1} \times {10}^{4} )(8 \times {10}^{8} )[/tex]

[tex] = (15 \times {10}^{4 - 1} )(8 \times {10}^{8} )[/tex]

First law of indices applied there

=(15×10^3)(8×10^8)

=(15×8)(10^3×10^8)

=120×10^3+8 ( first law of indices, which states that , numbers of the same base multiplying each other, take one of the base and add the exponent. and clearly both 15 and 8 are in base 10

=120×10^11

=1.20×10^2 ×10^11

=1.20×10^11+2

=1.20×10^13

We write standard numbers in scientific form as it can be written in more compact way.Think of writing a billion in copy and writing it in scientific notation.

Let us first multiply the bases which are (8×1.5) = 12 and 10⁴×10⁸ is 10⁴⁺⁸ = 10¹².

∴ (1.5×10⁴)(8×10⁸) = 12×10¹² but is scientific natation base should be less than 10 so we'll a decimal one digit before 12 like dividing it by 10 so to balance it out we also have to multiply by 10 we'll multiply that 10 to the 10¹² which will make it 10¹³.

Answer:

(a). $20,000

(b). The estimate will be lower than the actual amount.

Step-by-step explanation:

We have been given that Michael saves $423 dollars a month for college.

(a). We know that 1 year equals 12 months.

4 years = 4*12 months = 48 months.

[tex]\text{Actual amount saved}=\$423\times 48[/tex]

Since we are asked to find the estimated amount of money Michael will save in 4 years, so we will estimate both quantities as:

[tex]423\approx 400\\\\48\approx 50[/tex]

[tex]\text{Actual amount saved}=\$400\times 50[/tex]

[tex]\text{Actual amount saved}=\$20,000[/tex]

Therefore, Michael will save approximately $20,000 in 4 years.

(b).

The estimate will be lower than the actual amount as we rounded $423 down $23 to nearest hundred that is $400 and rounded 48 up 2 to nearest ten that is 40.

Therefore, the estimate will be lower than the actual amount.
