A. 2/15
B. 8/15
C. 5/6
D. 6/5
Answers
Answer:
D
Step-by-step explanation:
since all you need to do is set up the equation 4/5/2/3 which is basically dividing the fractions so it would be set up as this 4/5*3/2 which is 12/10 and simplifed would be 6/5 also 6/5*2/3 is 4/5 so it would be the correct answer.

if u wouldnt mind giving me brainliest, just tryna rank up
The value of the expression at y = 2.5 is 6.25.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
y²
Substitute y = 2.5
= y²
= 2.5²
= 2.5 x 2.5
= 6.25
Thus,
The value is 6.25.

In a regular polygon, the measure of an interior angle is 6.5 times the measure of an exterior angle. How many sides does the polygon have?
Answers
Answer:
15 sides
Step-by-step explanation:
Always the sum of interior angle and exterior angle = 180
Let the exterior angle = x
Interior angle = 6.5 *x = 6.5x
x + 6.5x = 180
7.5x = 180
x = 180/7.5
x = 24
Exterior angle = 24°
Sum of exterior angles of any polygon = 360
number of side = Sum of exterior angles ÷ measure of each exterior angle
= 360 ÷ 24
= 15

Solve for a:
a – 17 = -15
A. a = -32
B. a = 2
C. a = 32
D. a = 12
Answers
Answer:
B
Step-by-step explanation:
a-17=-15
so the whole point of solving problems like this is to get the variable on one side (a in this case) and the constants on the other side (-17 and -15 in this case).
so to get rid of the 17 because its negative you have to add 17 or do the inverse sign but whatever you do to on side you have to do to the other side so you add 17 to both side
-17+17 they cancel out
-15+17=2
so now we get that a=2
your answer would be B
hope this helps :D

Use the drop-down menus to build an equation that could be used to find the percent change, p, in the number of students.
Answers
Answer:
26.7%
Step-by-step explanation:
The positive change from 15 to 19 is 4.
Find the value of the fraction 4/15 and multiply the result by 100% to obtain the final answer:
4/15 = 0.26667
Multiplied by 100%, 0.26667 becomes 26.7%: the percentage change in the number of students

Answer: He works 16 hours a day
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
121×43=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
12×41×3=483
Since 48 divided by 3 equals 16 then,
483=16
Therefore:
121÷34=16
Solution by Formulas
Apply the fractions formula for division, to
121÷34
and solve
12×41×3
=483
=16
Therefore:
121÷34=16
