Answer:

$\large\boxed{Q\#1.\ A)\ \dfrac{8}{3}x+6}\\\boxed{Q\#2.\ A)\ \dfrac{1}{3}(p+45)}$

Step-by-step explanation:

$Q\#1:\\\\\dfrac{2}{3}(4x+9)\qquad\text{use the distributive property}\\\\=\left(\dfrac{2}{3}\right)(4x)+\left(\dfrac{2}{3}\right)(9)=\dfrac{8}{3}x+(2)(3)=\dfrac{8}{3}x+6\\\\Q\#2:\\\\\dfrac{1}{3}p+15=\dfrac{1}{3}p+\dfrac{1}{3}\cdot(3)(15)=\dfrac{1}{3}p+\dfrac{1}{3}\cdot45=\dfrac{1}{3}(p+45)$

10n + 0.3 = 0.1n + 0.3

egoroff_w [7]

Answer:

n = 0

Step-by-step explanation:

Let's solve for n, according to the linear equation given, this way:

10n + 0.3 = 0.1n + 0.3

10n - 0.1n = 0.3 - 0.3 (Like terms)

9.9n = 0

n = 0/9.9

Find the y and x intercept 6x-8y=48

Crank

6x-8y=48

to find the x intercept set y=0

6x - 8*0 = 48

6x = 48

divide by 6 on each side

x =48/6

x=8

(8,0)

to find the y intercept set x=0

6(0) - 8y = 48

0 - 8y = 48

-8y = 48

divide by -8 on each side

y = -6

(0,-8)

Option a: multiply $\frac{2}{5}$ by 4.

Explanation:

The expression is $\frac{2}{5} \div \frac{1}{4}$

Dividing the two fractions which is the same as multiplying the first fraction by the reciprocal value of the second fraction.

Hence, it can be written as

$\frac{2}{5} \times \frac{4}{1}=\frac{8}{5}$

Hence, $\frac{8}{5}$ is the quotient.

Option a: multiply $\frac{2}{5}$ by 4.

To determine the quotient, let us multiply the term $\frac{2}{5}$ by 4, we get,

$\frac{2}{5} \times 4=\frac{8}{5}$

Hence, $\frac{8}{5}$ is the quotient.

Thus, Option a is the correct answer.

Option b: multiply $\frac{2}{5}$ by $\frac{1}{4}$

To determine the quotient, let us multiply the term $\frac{2}{5}$ by 4, we get,

$\frac{2}{5} \times \frac{1}{4}=\frac{1}{10}$

$\frac{1}{10}$ is not the quotient. Since, the quotient is $\frac{1}{10}$ which is not equivalent to $\frac{8}{5}$ and hence we cannot multiply $\frac{2}{5}$ by $\frac{1}{4}$

Hence, Option b is not the correct answer.

Option c: multiply $\frac{5}{2}$ by $\frac{1}{4}$

To determine the quotient, let us multiply the term $\frac{5}{2}$ by $\frac{1}{4}$ , we get,

$\frac{5}{2} \times\frac{1}{4}=\frac{5}{8}$

$\frac{5}{8}$ is not the quotient. Since, the quotient is $\frac{5}{8}$ which is not equivalent to $\frac{8}{5}$ and hence we cannot multiply $\frac{5}{2}$ by $\frac{1}{4}$

Hence, Option c is not the correct answer.

Option d: multiply $\frac{5}{2}$ by 4

To determine the quotient, let us multiply the term $\frac{5}{2}$ by 4, we get,

$\frac{5}{2} \times4=10$

10 is not the quotient. Since, the quotient 10 which is not equivalent to $\frac{8}{5}$ and hence we cannot multiply $\frac{5}{2}$ by 4.

Hence, Option d is not the correct answer.

Solve 3x+5=18 in slope form?

prisoha [69]

There is no such thing as the slope form of an equation with only a single variable.

If 3x + 5 = 18, then x = 4 and 1/3 .

There's only a slope if the equation makes a line on a grapoh.
This equation only makes a single point.
