Kaylis [27]2 years ago

Answer:

x\geq 12

x is greater than or equal to 12

Step-by-step explanation:

We first start off with recognizing that this is an <u>inequality</u>, and that the answer choices involve <u>solving for </u>x.

I suggest that you write out the steps <em>one-by-one</em> and don't skip any so that making a mistake is less likely.

<u>Rewrite the original equation:</u>

-\frac{3}{4}x + 2 \leq -7

<u>Use reverse PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) order to isolate </u>x:

Subtract 2 from both sides: -\frac{3}{4} x \leq -9

Divide both sides by -\frac{3}{4} (this flips the inequality symbol since we're dividing by a negative number): x\geq 12

Your final answer is:

x \geq  12

x is greater than or equal to 12

If you want to do any <u>further reading</u> on this topic, search up videos and other helpful resources by putting, "Solving Inequalities" into your preferred search engine.

A right triangle has legs measuring 4.5 meters and 1.5 meters. The length of tge legs of a second triangle are proportional to t
Leviafan [203]
If the legs of both triangles are supposed to be proportional then they would be equal in length because that's what proportional means

so if the legs of one triangle are 4.5 and 1.5 then the other triangle "if proportional" would have legs with the same measurements which are 4.5 and 1.5

The radius of a cylinder is increased by 5 percent. Given that the height is constant, find the percentage increase in volume. ​
telo118 [61]

Step-by-step explanation:

Volume =pir^h

V1=pi r1^h

V2=pir2^2h

Now,V1/V2=r1^2/r2^2

v1/v2=r1^2/(1.05)^2 ((r2=r1+5/100r1)

v1/v2=1/1.1025

v1/v2=0.907

(v1/v2-1)=0.0907×100%

(v1-v2)/v2=9.07%

increase in volume is 9.07%

Sales tax in your community is 5. 25 cents for each dollar spent. What is the total cost at the movies for three tickets at
Montano1993 [528]

Answer:

33.94

Explanation:

First start off by finding the total regardless of the 5.25 cents.

(3x8.50)+(3x1.25)+(2x1.50)=32.25

Then take that answer and multiply by your 5.25 cents per dollar

32.25x.0525 (since we're dealing with money)

then add that answer to the original 32.25

5-(-4)=5+<br> write as addition
Furkat [3]

Answer:

5+4

Step-by-step explanation:

Based off the typical rules of integers, expressions like these can be simplified to look different but mean the same thing.

5 - (-4) = 5+4

In this case, we subtracted a negative value from a positive value; by doing this, we actually added positive 4.

Based on the same principals, adding a negative number is equivalent to subtraction!

Any time you see equations similar to this, you want to cancel out the 2 negative signs to make it positive!

Please look at the attached file for more information :)
