x=4/7
Step-by-step explanation:
get x alone.
1st get 3 on the other side of the = sign by using the opposite sign. the opposite of addition is subtraction
-5x+3=2x-1
-3 -3
-5x=2x-1-3
-5x=2x-4
now we get the xs together. the opposite of addition( the 2 is positive) is subtraction
-5x=2x-4
-2x -2x
-7x=-4
now let's get the -7 out of here. -7 is multiplying by x. the opposite of multiplication is division.
<u>-7x</u><u> </u>= <u>-</u><u>4</u>
-7. -7
x=-4/-7
negative divided by a negative is a positive
x=4/7
Answer:
117 degrees
so a line is 180 degrees so the 63 +x=180
find x
180-63=117
sine:<span> the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right triangle) to the hypotenuse.
</span>cosine: the trigonometric function that is equal to the ratio of the side adjacent to an acute angle (in a right-angled triangle) to the hypotenuse.
tangent: <span>a straight line or plane that touches a curve or curved surface at a point, but if extended does not cross it at that point.</span>
Answer:
1/4
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
the probability that a randomly chosen radio station in this city is a college radio station = number of college stations / total number of city radio stations
= 5/20
To transform to the simplest form. divide both the numerator and the denominator by 5
= 1/4
Answer:
2 1/2
Step-by-step explanation:
If you do the step by step calculation:
Step 1: Simplify both sides of the equation.
2(12+2x+15+2x)=74
(2)(12)+(2)(2x)+(2)(15)+(2)(2x)=74(Distribute)
24+4x+30+4x=74
(4x+4x)+(24+30)=74(Combine Like Terms)
8x+54=74
8x+54=74
Step 2: Subtract 54 from both sides.
8x+54−54=74−54
8x=20
Step 3: Divide both sides by 8.
8x divide by 8 and that is 20 divided by 8
leaves you with the answer 5/2.
If you then turn the improper fraction into a mixed fraction you get 2 and one half.
Answer= 2 1/2 or "a" <u>DEPENDS ON WHAT QUIZ YOU HAVE</u>
