x/50=40/64 solve for x

Answers

X/50 = 40/64

To find x cross multiply:

64 * x = 50 * 40

Simplify:

64x = 2000

Divide both sides by 64:

X = 31.25

Answer:

x = [tex]\frac{125}{4}[/tex]

Step-by-step explanation:

[tex]\frac{X}{50}[/tex] = [tex]\frac{40}{64}[/tex]

Divide both sides of the equation by the coefficient of variable

X = [tex]\frac{40}{64}[/tex] x 50

Simplify the fractions:

x = [tex]\frac{5}{4}[/tex] x 25

Write as a single fraction

x = [tex]\frac{5*25}{4}[/tex]

Calculate the product:

x = [tex]\frac{125}{4}[/tex]

Answer:

measure of Arc(DE) = 167°

Step-by-step explanation:

Since the arc EFG make a straight angle, we can infer;

180° = Arc(EF) + Arc(FG)

180° = (x-3)° + (12x - 25)°

180° = 13x - 28

208 = 13x

16 = x

Arc GF and DE are vertical angles so if you find the measure of Arc GF then it's the same as measure of Arc DE

mDE = mGF

mDE = 12x - 25

mDE = 12(16) - 25

mDE = 192 - 25

mDE = 167°

Kenzie bought 12 belts for $54 write an equation that shows the relationship between the numbers of belt B and C the total cost for the belts

Answers

Answer:

$4.50B = C

Step-by-step explanation:

Kenzie bought 12 belts for $54, which means that each belt costs $4.50.

If b=number of belts, c=the total cost, and x=the cost of one belt, the equation would be:

b(x)=c,

so:

12*$4.50=$54

OR

$4.50B=C

hope that helps! good luck!

Answer:

C = 4.50B

Step-by-step explanation:

Finding the cost of a belt

Total cost / Number of belts$54 / 12$4.50

Therefore, the relation between B, the number of belts, and C, the total cost, will be :

C = 4.50B
