We have to make sure the denominators are equal.

10 goes into 5 evenly, so we only need to multiply one term to get a common denominator.

Multiply 2 by 2, and get 4, then we multiply 5 by 2 and get 10

Now the equation is 4/10 + 6/10

Since our denominators match, we can add the numerators.

4 + 6 = 10

That gives us the sum, which is 10/10 aka 1 whole

Answer:

2/5 + 6/10 = 1

Step-by-step explanation:

first let’s change 2/5 so it has the same denominator as 6/10.

2/5 * 2/2 = 4/10

now add

4/10 + 6/10 = 1

a carton contains 1 3/4 quarts of ice cream. One serving is a 1/5 of a quart. How many servings are in the carton?

Answer: 8 3/4

Explanation: Well in order to solve this equation, you must make the denominators equivalent. A common factor between 4 and 5 is 20. But since we multiplied the denominators, we have to do the same to the numerators. 3 x 5 = 15. 1 x 4 = 4. Our new fractions are now 1 15/20 and 4/20. Now that we have made our denominators equivalent, we can divide. 1 15/20 divided by 4/20 is 8 15/20. But we are not done yet, after we must simplify the fraction. Which would be 8 3/4.

14. Find the slope of the line passing through the points (8, 15) and (5,9).

gizmo_the_mogwai [7]

We have $P_1(x_1,y_1)\to P_1(8,15)$ and $P_2(x_2,y_2)\to P_2(5,9)$ .

The slope is

$m=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{9-15}{5-8}=\dfrac{-6}{-3}=\boxed{2}$

Hope this helps.

Answer:

$\large\boxed{3\sqrt{16}+\sqrt{-9}=12+3i}$

Step-by-step explanation:

$3\sqrt{16}+\sqrt{-9}\\\\\sqrt{16}=4\ \text{because}\ 4^2=16\\\\\sqrt{-9}=\sqrt{(9)(-1)}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\=\sqrt9\cdot\sqrt{-1}=(**)\\\sqrt9=3\ \text{because}\ 3^2=9\\\sqrt{-1}=i\\(**)=3i\\\\3\sqrt{16}+\sqrt{-9}=(3)(4)+3i=12+3i$

find the equation of the line that passes through (2,-1) and is parallel to 2x+y-4=0. leave your answer in the form y=mx+c

Tomtit [17]

Answer:

y = - 2x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + y - 4 = 0 ( subtract 2x - 4 from both sides )

y = - 2x + 4 ← in slope- intercept form

with slope m = - 2

Parallel lines have equal slopes , thus

y = - 2x + c ← is the partial equation

To find c substitute (2, - 1) into the partial equation

- 1 = - 4 + c ⇒ c = - 1 + 4 = 3

y = - 2x + 3 ← equation of parallel line
