Perform the operations and write the answer in simplest form 2 2/5 + 3 1/4

iragen [17]

Answer: 2 2/3

Step-by-step explanation:

we have to turn this into a improper fractions first (so its something like a bobble-head)

(2 2/5) 5 x 2 = 10 + 2 = 11/5

(3 1/4) 3 x 4 = 12 + 1 = 13/4

Then add those two.

11/5 + 13/4

11 + 13 = 24

5 + 4 = 9

so now its time to put it in simplest form 8/3

Now 8 divided by 3...BUT WAIT...3 can't go into 8

Now we turn it into a Mixed Number 2 2/3

Instructions: Simplify the algebraic expression.<br><br> −12(32x−10y)

allochka39001 [22]

Answer:

-384x - 120y

Step-by-step explanation:

General Concepts and Formulas:

Brackets

Parentheses

Exponents

Multiplication

Division
Addition
Subtraction

Steps:

1) Distribute

$-12(32x-10y)$

We must distribute the expression above by multiplying -12 by the coefficients and then adding the variables.

So first, multiple -12 by 32 and add the variable 'x' when getting the product:

-12(-384x - 10y)

Now that we have one part, let's solve the other part.

We now must multiple -12 by -10, which gets us 120, now we must plug in:

(-384x - 120y)

(Remove parenthesis)

⇒ -384x - 120y

Suppose a hot air balloon begins descending at a rate of 30ft/min from an elevation of 1250ft. Write an equation to model the ho

galina1969 [7]

Base elevation is 1250 ft
rate is 30 per minute 30m
so, h = 1250 - 30m
as an inclusion, 30 ft per minute is also like 0.5 per second like 1250 - 0.5s
1250/30 means it would be about 42 minutes once it touches the ground.

Find the measure of angle x in the figure below: A triangle is shown. At the top vertex of the triangle is a horizontal line ali

VLD [36.1K]

Answer:

$x=35^\circ$

Step-by-step explanation:

From the diagram which I have drawn and attached below:

$56^\circ+y+51^\circ=180^\circ$ (Sum of Angles on a Straight Line)\\y=180^\circ-(56^\circ+51^\circ)\\y=73^\circ$

Next, in the triangle, the sum of the three interior angles:

$y+x+72^\circ=180^\circ\\$Since y=73^\circ\\73^\circ+x+72^\circ=180^\circ\\x=180^\circ-(73^\circ+72^\circ)\\x=35^\circ$

The value of angle x is 35 degrees.
