11a+9=4a+30 what is the answer

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

Carly has 2 dimes and 4 nickels in her pocket.

Let's assume Carly has x dimes in her pocket. Since Carly has 2 more nickels than dimes, she would have x + 2 nickels. The value of x dimes is 10x cents and the value of (x + 2) nickels is 5(x + 2) cents. Since Carly has 40 cents in total, we can set up the equation: 10x + 5(x + 2) = 40.

Simplifying the equation gives us: 10x + 5x + 10 = 40. Combining like terms gives us: 15x + 10 = 40. Subtracting 10 from both sides gives us: 15x = 30. Dividing both sides by 15 gives us:
x = 2.

Therefore, Carly has 2 dimes and 4 nickels.

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 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).

Answer:

y<3

Step-by-step explanation:

Do you do rsm lol

y<3 is the value.

In mathematics, an inequality is a relation that makes a non-equal assessment between two numbers or different mathematical expressions. Its miles are used most often to evaluate numbers at the quantity line by means of their size. There are several unique notations used to represent exceptional types of inequalities:

The notation a < b means that a is less than b.

The notation a > b approach that a is greater than b.

The range of y which will satisfy this inequality will result in the first fraction of a larger value as compared to the second fraction.

Multiplying both sides of an inequality by 12, we get:

12×10>12×3y-7/12

2(7-2y)>3y-7

14-4y3y-7

14+7>3y+4y

21> 7y

Answer:

The function is [tex]C(x)=7x[/tex]

Step-by-step explanation:

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.

So, The cost for 4 hour is [tex]C(x)=7\times 4[/tex]

[tex]C(x)=\$28[/tex]

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.

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.

Answer:

1/6

Step-by-step explanation:

1/2 * 1/3 = 1/6.

Answer:- 512

Explanation:-

We know that [tex](m+1)^{th},\ (T_{m+1})[/tex] in the binomial expansion [tex](p+q)^n[/tex] is given by

[tex]T_{m+1}=^nC_m\ p^{n-m}q^m[/tex]

Assume that [tex]x^9y[/tex] occurs in the [tex](m+1)^{th}[/tex] term of the expansion of [tex](2y+4x^3)^4=(4x^3+2y)^4[/tex]

[tex]T_{m+1}=^4C_m\ (4x^3)^{4-m}(2y)^m[/tex]

Comparing power of x and y in  [tex]x^9y[/tex]  we get m=1

Thus term for m=1 [tex]=\ ^4C_1\ (4x^3)^{3}(2y)^1=^4C_1=\frac{4!}{(4-1)!1!}(64x^9)(2y)=4(128x^9y)=512x^9y[/tex]

Thus the coefficient of [tex]x^9y[/tex] is 512.

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

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.
