Final answer:

The problem is a middle school mathematics question about algebra and age. By setting up an equation and solving it, we found that Josh is currently 27 years old.

Explanation:

The subject of this question is Mathematics, and it is likely a Middle School level problem. To solve this, we set up an equation based on the information provided: Let's denote Delaney's current age as D. According to the question, Josh is 4 years older than Delaney, so Josh's current age is D + 4 years. In 5 years, Delaney will be D + 5 years old, and Josh will be (D + 4) + 5 which simplifies to D + 9 years old. We know that the sum of their ages in 5 years will be 60. Therefore, the equation is:

D + 5 + D + 9 = 60

Combining like terms, we get:

2D + 14 = 60

Subtracting 14 from both sides, we get:

2D = 46

Divide both sides by 2 to find Delaney's current age:

D = 23

Now, we can determine Josh's current age by adding 4:

Josh's age = D + 4 = 23 + 4 = 27

Therefore, Josh is currently 27 years old.

Answer:

the range will be 248 ≤ x ≤ 370

Step-by-step explanation:

The given inequality models the range of amount of gems.

132 ≤ 1/2x + 8 ≤ 193

So we have to solve the inequality for the value of x.

132 ≤ [tex]\frac{1}{2}x[/tex] + 8 ≤ 193

Now we subtract 8 from the inequality.

132 - 8 ≤ ([tex]\frac{1}{2}x[/tex] + 8) - 8 ≤ 193 - 8

124 ≤ [tex]\frac{x}{2}[/tex] ≤ 185

Now we multiply the inequality by 2

124 × 2 ≤ [tex](\frac{x}{2})[/tex] × 2 ≤ 185 × 2

248 ≤ x ≤ 370

So the range will be 248 ≤ x ≤ 370

The equation of a line with a given slope and passing through a point can be found using the point-slope formula.

To find the equation of a line with a given slope (m) passing through a point (a, c), we can use the point-slope formula. The point-slope formula is given by:

y - c = m(x - a)

where (x, y) represents any point on the line. This equation represents a line with slope m passing through the point (a, c).

The factors of 26 are one, two, 13 and 26. One and the number itself, in this case 26, are always factors. Since 26 is an even number, which means that it ends in zero, two, four, six or eight, it's evenly divisible by two. Two times 13 equals 26.

Answer:

Negative.

Step-by-step explanation:

The answer is negative, because if the number of integers you are multiplying is odd, then the sign is negative. But if the number of integers you are multiplying is even, then the sign is negative. In this case, three is odd, so the sign is negative.

Answer:   B. 25%

Step-by-step explanation:

Given : Number of boys in the class = 13

Number of girls in the class = 9

Total students  = 13+9=22

Now, the number of ways to choose first boy then a girl =[tex]13\times9=117[/tex]     (1)

Number of ways to choose nay two students :-

[tex]{22}P_{2}=\dfrac{22!}{(22-2)!}\\\\=\dfrac{22\times21\times20!}{20!}=462[/tex]     (2)

Now, the probability that the first student chosen is a boy and the second student chosen is a girl :-

[tex]\dfrac{117}{462}=0.253246753247\approx0.25[/tex]   [Divide (1) by (2)]

In percent , [tex]0.25\times100=25\%[/tex]

Hence, approximately 25% chance that the first student chosen is a boy and the second student chosen is a girl.

Answer:

divide the unit by the the total amount

The answer is 0. 74

Answer:

58%

Step-by-step explanation:

Let us suppose x percent of 86 is 50.

Therefore, we have the below equation

x% of 86 = 50

Eliminating percentage, we get

0.0x × 86 = 50

Solve for x

[tex]0.0x\times86=50\\\\0.0x=\frac{50}{86}\\\\x=\frac{50}{86}\times100\\\\x=58.1[/tex]

Hence, in nearest whole percent, we have

x = 58%

Therefore, 58% of 86 is 50

The temperature at midnight was 25 degrees.

We have at one winter night the temperature fell 16 degrees between midnight and 5 A.M. By 9 A.M. the temperature had doubled from what it was at 5 A.M. By​ noon, it had risen another 12 degrees to 30 degrees.

We have to determine the temperature at​ midnight?

Degree of hotness or coldness measured on a definite scale is called Temperature. When the temperature of the body is high it is called hot body and when it is low it is called cold body.

According to the question -

Assume the temperature at mid - night be x and at 5 AM be y.

Then -

x - y = 16

At 9 A.M. , assume the temperature to be z. Then -

z = 2y

At Noon -

z + 12 = 30

z = 30 - 12

z = 18 degree

At 9 A.M., we have -

z = 2y

18 = 2y

y = 9 degrees

At mid - night, we have -

x - y = 16

x - 9 = 16

x = 25 degrees

Hence, the temperature at midnight was 25 degrees.

Given : Charles will babysit for up to 4 hours and charges $7 per hour.

To find : Write a function in function notation for this situation ?

Solution :  

Let the work done by Charles in 'x' hour.

The charges is $7 per hour.

To create a function of x,

The cost function of 'x' hour is [tex]C(x)=7x[/tex]

Charles will babysit for up to 4 hours.

Answer:

5

Step-by-step explanation:

I put 5.7143

but they told me it was 5

ur welcome

none of them.

 Product means multiplication, so the product of 5 and a number means 5 times a number which is 5x

 so if 5x = 14

x = 14/5 = 2.8

x = 2.8 which isn't a choice.

Answer:

The answer is B 1/20

Step-by-step explanation:

The word "Product" means multiplication, and we need to find the value of "x" here's an equation:

5 times x = 1/4

5 times 1/20 = 1/4
