Answer:

12 11/35

Step-by-step explanation:

Given Data

First term= 15 3/5

To simple fracrion= 78/5

Second term= 3 2/7

To simple fracrion= 23/7

Hence the operation goes thus

= 78/5- 23/7

LCM = 35

=546-115/35

=431/35

=12 11/35

Answer:

[tex] 12 \frac{11}{35} = \frac{431}{35} [/tex]

Step-by-step explanation:

[tex]15 \frac{3}{5} - 3 \frac{2}{7} \\ (15 - 3) + ( \frac{3}{5} - \frac{2}{7} ) \\ 12 + ( \frac{3}{5} - \frac{2}{7} ) \\ 12 + \frac{11}{35} [/tex]

[tex] \boxed{Answer:{\boxed{\green{= 12 \frac{11}{35} = \frac{431}{35}}}}} [/tex]

Answer:

∠ABC= 82°

∠ACB= 82°

∠BAC= 16°

Step-by-step explanation:

∠ABC +∠ACB +∠BAC = 180° (∠ sum of △ABC)

(5x -3)° +(5x -3)° +(x -1)°= 180°

5x -3 +5x -3 +x -1= 180

11x -7= 180 (simplify)

11x= 180 +7 (+7 on both sides)

11x= 187

x= 187 ÷11

x= 17

∠ABC

= (5x -3)°

= [5(17) -3]°

= 82°

∠ACB

= ∠ABC

= 82°

∠BAC

= (17 -1)°

= 16°

Alternatively,

∠BAC

= 180° -82° -82°

= 16°

x is equals to 4 and y is equal to 1

Step-by-step explanation:

3x+3y=9

x-3y=7

elimination method has to do with eliminating one variable from the question to eliminate y we have to add the equations together which is 4x=16

X=4

substitute x is equal to 4 into any equation of your choice let's use equation 1

E

3(4)+3y=9

12+3y=9

12-9=3y

3=3y

divide both sides by 3 therefore y is equal to 1.

Step-by-step explanation:

First we count the number of beans in total which is 20

Then we count the number of red beans which is 6

6/20 can be simplified to 3/10

Answer:

C) 3/10

Step-by-step explanation:

There are 6 red + 5 blue + 4 green + 5 black = 20 jelly beans in total

Since there are 6 red jelly beans, the probability of randomly selecting a red jelly bean is 6 red jelly beans / 20 total jelly beans = 6/20 = 3/10

Answer:

6

Step-by-step explanation:

geometric sequence is given as Tn=ar^n-1

where Tn is the last term,a is the first term, r is the common ratio, n is the nth term

hence 48=a2^(4-1)

48=a2^3

48=a8 (divide both by 8 to ramain with a)

6=a

therefore the first term is 6 .

Answer:

-31/17

Step-by-step explanation:

csc²α-cot²α=1

cot²α=csc²α-1=(25/7)²-1=(625-49)/49=576/49

α is in 2nd quadrant so cotα is negative.

cot α=-√(576/49)=-24/7

tan α=-7/24

cos β=√2/2

sec β=2/√2=√2

sec²β-tan ²β=1

tan ²β=sec²β-1

tan²β=(√2)²-1=2-1=1

β is in 1st quadrant ,so tan β is positive.

tan β=1

[tex]tan (\alpha -\beta )=\frac{tan \alpha -tan \beta }{1+tan \alpha tan \beta } \\=\frac{\frac{-7}{24} -1}{1+(\frac{-7}{24}) (1)} \\=\frac{-7-24}{24-7} \\=\frac{-31}{17}[/tex]

Step-by-step explanation:

Answer:

Number of trout caught by Bill = 16 trout

Number of trout caught by Steve = 30 trout

Step-by-step explanation:

Given:

Total number of trout caught = 46

Number of trout caught by Steve = Number of trout caught by Bill + 14

Find:

Number of trout caught by Steve

Number of trout caught by Bill

Computation:

Assume;

Number of trout caught by Bill = a

Number of trout caught by Steve = a + 14

So,

Number of trout caught by Steve + Number of trout caught by Bill = Total number of trout caught

a + a + 14 = 46

2a = 46 - 14

2a = 32

a = 16

Number of trout caught by Bill = 16 trout

Number of trout caught by Steve = a + 14

Number of trout caught by Steve = 16 + 14

Number of trout caught by Steve = 30 trout
