The required solution of the linear equation is x = 6.

What is linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Given [tex]\frac{3x}{2} - \frac{2x}{3}=5[/tex]

[tex]\frac{3x}{2} - \frac{2x}{3} = 5\\ \Rightarrow \frac{9x-4x}{6} = 5\\ \Rightarrow \frac{5x}{6} = 5\\\Rightarrow 5x = 30\\\Rightarrow x = 6[/tex]

Therefore, the required solution of the linear equation is x = 6.

answer:

-29

step-by-step explanation:

you need a graphing calculator.

so, let's start by setting up a table (for my sake because that text is confusing)

x       f(x)      g(x)      h(x)

-3      12        39          -14

0       0         3           1

1        0         7           -2

3       6        39         -20

okay, that's out of the way. now, your equation is 2 * f(3) - 3 * g(1) + h(3).

for f(3), we look at the chart to see which f(x) value matches x=3.

f(3) = 6

same with g(1) and h(3)

g(1) = 7

h(3) = -20

now, replacing the functions(x) with their numbers is the next step.

2 * 6 - 3 *7 + (-20)

(2*6) - (3*7) - 20

(12) - (21) - 20 = -29

Answer:

The sum of the angles is 180°.

We already know that one angle is 90°, and the other one is 38.

so: 180-(90+38)=52°

the exterior angle+52°= 180° (beacuse the form a flat angle)

so x=180-52

so: x=128°.

Answer:

128°

Step-by-step explanation:

We know that,

   the exterior angle of a triangle is equal to the sum of the interior opposite angles of a triangle.

Accordingly,

38 + 90 = x

128° = x

Answer: Width = 3.4 meters, Length = 6.4 meters

Step-by-step explanation:

If the width is [tex]w[/tex], then the length is [tex]w+3[/tex].

[tex]w(w+3)=22\\\\w^2 +3w=22\\\\w^2 +3w-22=0\\ \\ w=\frac{-3 \pm \sqrt{3^2 -4(1)(-22)}}{2(1)}\\\\w \approx 3.4 \text{ } (w > 0)\\\\\implies w+3 \approx 6.4[/tex]

Answer:

[tex] \huge{ \boxed{gof(3) = 9}}[/tex]

Step-by-step explanation:

In order to find gof(3), we first have to find gof(x). To find gof(x) substitute the f(x) into g(x). That is, for every x found in g(x) substitute it by f(x).

From the question

[tex]f(x) = 2 {x}^{2} - x - 15 \\ g(x) = - 5x + 9 \\ \\ gof(x) = - 5(2 {x}^{2} - x - 15) + 9 \\ gof(x) = - {10x}^{2} + 5x + 75 + 9 \\ \\ gof(x) = - {10x}^{2} + 5x + 84[/tex]

To find gof(3), substitute the value of x that is 3 into gof(x). For every x found in gof(x), replace it by 3 and solve.

[tex]gof(3) = - 10( {3})^{2} + 5(3) + 84 \\ \quad \: \: \: \: \: = - 10(9) + 15 + 84 \\ \: \: \: = - 90 + 15 + 84 \\ = 9[/tex]

We have the final answer as

Answer:

63 days

Explanation:

Given the total number of days in a yesr = 180 days

Percent of the time he walks to school = 35 %

Number of days he walks to school = 35% of 180

Number of days he walks to school = 0.35 * 180

Number of days he walks to school = 63 days

Hence the number of days he walked to schools is 63 days

Answer: B 10.6

Explanation:

We would assume that the stock tank is cylindrical. We would calculate the volume by applying the formula,

Volume = πr^h

where

π = 3.14

r is the radius of the cylinder

h is the height of the cylinder

From the information given,

diameter = 3

radius = diameter/2 = 3/2

r = 1.5

h = 1.5

Volume = 3.14 x 1.5^2 x 1.5 = 10.5975 cubic meters

By rounding to the nearest tenth,

Volume = 10.6 cubic meters

we have the expression

===========================

We know parallel lines have equal slopes, so line r has the slope of - 1.

Line r is:

Substitute the coordinates of the point into this equation and find the value of b:

The equation of line r is:

EXPLANATION

If the measure of ∠2= x+78 and the other ∠=40 degrees, by definition we know that sum of interior angles of a triangle is equal to 180 degrees.

Furthermore, we have two congruent legs, so this is an Isosceles triangle with two congruent angles (with the same measure).

Thus,

180 = 40 + 2* m∠2

Substituting m∠2 by the equation as follows:

180 = 40 + 2(x + 78)

Subtracting -40 to both sides:

180 - 40 = 2(x+78)

Simplifying:

140 = 2(x+78)

Dividing both sides by 2:

140/2 = x + 78

Simplifying:

70 = x + 78

Subtracting -78 to both sides:

70 - 78 = x

Simplifying:

-8 = x

Switching:

x = -8

Answer: The value of x is -8.

Answer:

No

Explanation:

To determine if the lengths form the side of a right triangle, use the Pythagorean Theorem:

Substitute 15,11 and 4 into the formula:

Since the Pythagorean Theorem does not hold, the side lengths(15,11,4) do not represent the lengths of the sides of a right triangle.

The proper sampling technique used when the number of samples is less than 100 is saturated sampling where the entire population will be the research sample.

What is saturated sampling ?

According to Arikunto if the population is less than 100 people so the researcher need to take all the samples namely saturated sampling.

What is stratified sampling ?

Stratified sampling is a sampling technique which used when we do a research on a heterogenous population. How to use this technique is to divide the population into several stratum and then take random samples from each stratum an then all the samples that have been taken are collected into one sample.

In conclusion, if the population has fewer than 100 people , the expert suggested to use saturated sampling.

The percent of decrease, for the amount of flour, is 56.63%.

A percentage is a number that tells us how much out of 100.

Given that, at the beginning of a baking session, there were 2.26 kilograms of flour in the bag, by the end if the baking session, there was 0.98 kilograms of flour in the bag

The amount percentage left = (2.26 - 0.98)/2.26*100 = 56.63%

Addition:

When we say "the addition," we mean adding two or more numbers together. The plus sign (+) denotes addition of two numbers, therefore three is written as three plus three. You also have control over how often the plus sign (+) is used. such as 3 + 3 + 3 + 3. Mathematical addition is an essential part of children's education. Students learn basic addition sums in primary school, including one-digit facts, math addition sums, and double-digit math addition sums.
