Joey's age is 3 less than twice his brother's age. Joey is 13 years old. How old is his brother?

Joey's brother is 8 years old.

Let's assume that:

As per the provided information, we are given that Joey's age is 3 less than twice his brother's age, we can write an equation:

[tex]\Large\qquad\quad\bigstar\:\:\boxed{\rm{\:\:y = 2x - 3\:\:}}[/tex]

We know that Joey is 13 years old. So we can substitute 13 for Joey's age in the equation and solve for x:

[tex]\Large\begin{aligned}\rm{13}&=\rm{2x - 3}\\\rm{13 \red{+3}}&=\rm{2x - \cancel{3 \red{+3}}}\\\rm{16}&=\rm{2x}\\\rm{\dfrac{16}{\red{2}}}&=\rm{\dfrac{\cancel{2}x}{\cancel{\red{2}}}}\\\bold{8}&=\rm{x}\end{aligned}[/tex]

[tex]\therefore[/tex] Joey's brother is 8 years old.

Answer:

Joey's brother is 8 years old.

Step-by-step explanation:

Let's denote Joey's brother's age as [tex]\bf{x}[/tex]. Since Joey's age is 3 less than twice his brother's age and Joey is 13 years old, we can write the equation:

[tex]\LARGE \boxed{13 = 2x - 3}[/tex]

Now, we need to isolate [tex]x[/tex]. First, we can add 3 to both sides:

Next, we can divide both sides by 2:

So, Joey's brother is 8 years old.

Answer:

x=175

Step-by-step explanation:

1st number = x

2nd number = x

3rd number = 1.6(2x)

x+x+1.6(2x)=910

x+x+3.2x=910

5.2x=910

x=175

The relation between wavelength and period of a wave is explained in the solution.

Wavelength is a characteristic of a wave that measures the distance between two points or particles that have the same phase of oscillation.

The relation between wavelength and period of a wave :-

In one period of a wave, one full cycle (peak through valley

and back to peak) passes by.

That means that the wave has moved by one wavelength.

Since speed is distance traveled / time spent, and a wave

moves a distance of one wavelength in a time of one

period, its speed must be:

speed = distance / time = wavelength / period

v = λ / p

We more often use frequency = 1 / period. Then:

speed = wavelength x frequency

v = λ x f

C. The city population increases by 1000 every year.

Step-by-step explanation:

A linear function of time means that over time, the city's population also changes and it is like a relationship between time and the growth. A and B only says that during that one year, it increased by 1000 so it is a temporary change and no growth was mentioned. C and shows that every year, there is a steady change (1000 per year) so it is a linear function. D's increase would be too drastic as the 10% increase would increase so it would not be a steady line so it is not a linear function.

Answer:

578

Step-by-step explanation:

118

+560

answer:678

678-100=578

The sum of 118 and 560 is the same as adding 100 to 578.

To find the sum of 118 and 560, we can add the hundreds, tens, and ones separately.

Starting with the ones, 8 + 0 = 8.

Then, moving on to the tens, 1 + 6 = 7.

Finally, adding the hundreds, 1 + 5 = 6. Combining these results, we get 678 as the sum.

However, if we add 100 to 578, we get 678, which is the same as the previous result. This happens because when we add 100 to the sum of 118 and 560, we essentially increase the hundreds place by 1 while keeping the tens and ones the same.

The final answer is 578.

Step-by-step explanation:

For a point to be the midpoint of a line segment, it must bisect it into two equal segments and be on the line segment (hence, colinear with the endpoints). All four B points are equidistant from points A and C, but aren’t colinear with A and C. Therefore, they aren’t all midpoints of line segment AC.

Answer:

45.1 cm^2

Step-by-step explanation:

We can break up the area of quadrilateral ABCD into the sum of the areas of right triangle ABD and triangle BCD.

Triangle ABD is a right triangle, so the legs can be used as base and heightto find the area.

area of triangle ABD = bh/2

area of triangle ABD = (AD)(AB)/2

sin <ADB = opp/hyp

sin 55 = AB/10

AB = 10 sin 55

cos <ADB = adj/hyp

cos 55 = AD/10

AD = 10 cos 55

area of triangle ABD = (10 cos 55)(10 sin 55)/2

area of triangle ABD = 23.5 cm^2

Triangle BCD is a scalene triangle. We know the measures of 2 angles and the length of the included side.

Find the measure of angle C.

m<BDC + m<CBD + m<C = 180

44 + 38 + m<C = 180

m<C = 98

Use the law of sines to BC.

BD/(sin C) = BC/(sin <BDC)

10/(sin 98) = BC/(sin 44)

BC = (10 * sin 44)/(sin 98)

BC = 7.01485

Now use BC and m<CBD to find the length of the altitude from C to side BD. Call the altitude h.

sin 38 = opp/hyp

sin 38 = h/BC

sin 38 = h/7.01485

h = 7.01485 * sin 38

h = 4.3188

Now use BD as the base and h as the height to find the area of triangle BCD.

area of triangle BCD = base * height/2

area of triangle BCD = BD * h/2

area of triangle BCD = 10 * 4.3188/2

area of triangle BCD = 21.6 cm^2

Now we add the areas of the triangles.

area of quadrilateral ABCD = 23.5 cm^2 + 21.6 cm^2

area of quadrilateral ABCD = 45.1 cm^2

Answer:

solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]

The graph is attached below.

Option C is correct option.

Step-by-step explanation:

We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]

First we will solve the inequality to find value of x

Solving:

[tex]\frac{7x-3}{9}\geq 8-2x[/tex]

Step 1: Multiply both sides by 9

[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]

Step 2: Adding 3 on both sides

[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]

Step 3: Add 18x on both sides

[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]

Step 4: Divide both sides by 25

[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]

So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]

The graph is attached below.

Option C is correct option.
