Step-by-step explanation:

given,

measures of 3 angles of triangle,

angle 1 = 3x

angle 2 = 2x + 15°

angle 3 = 3x + 5 °

sum of the angles should be 180°

so,

angle 1 + 2 + 3 = 180°

after inserting the values we got,

3x + 2x + 15 + 3x + 5 = 180°

→ 8x + 20 = 180°

→ 8x = 180 - 20 = 160°

→ x = 160/8 = 2

→ x = 20

therefore,

angle

1 = 3x = 3 × 20 = 60

2 = 2x + 15 = 2(20) + 15 = 55°

3 = 3x + 5 = 3(20) + 5 = 65°

as given,

their sum should be 180° so,

60 + 55 + 65 = 180°

hope this answer helps you dear....

I guess dear the measure of the angles of traingle have x in their expression!...if they have than this is the answer!

sherry has five times as many computer games as jay . Nairan has three times as many computer games as jay. sherry has 16 comput

Naddika [18.5K]

Answer:

Jay has 8 computer games

Step-by-step explanation:

Let

x -----> the number of computer games Sherry has

y -----> the number of computer games Jay has

z -----> the number of computer games Nairan has

we know that

$x=5y$ ----> equation A

$z=3y$ ----> equation B

$x=z+16$ ----> equation C

Substitute equation A and equation B in equation C and solve for y

$5y=3y+16$

$5y-3y=16$

$2y=16$

$y=8$

therefore

Jay has 8 computer games

Jill has been watching the squirrels that live in her neighborhood. The number of squirrels changes each week. n f(n). 1 8. 2 12

qaws [65]

Answer: D) $f(n)=8(1.5)^{n-1}$

Step-by-step explanation:

From the given table we can see that this is not representing a linear function as the rate of change is not constant.

So it can be exponential growth function $A(b)^{n-1}$ , where A is the initial amount , b is the multiplicative rate of growth and n is the time period in weeks.

Now here at n=1 , f(n)=8

Therefore, A=8

Now, for n=2

$f(2)=8(b)^{2-1}\\\Rightarrow12=8b\\\Rightarrow\ b=\frac{12}{8}\\\Rightarrow\ b=1.5$

By substitute the values of A and b in the above equation, we get the equation $f(n)=8(1.5)^{n-1}$

Therefore, the function best shows the relationship between n and f(n) is

$f(n)=8(1.5)^{n-1}$ , where n is the number of weeks.

What would you multiply the dividend and divisor by in the following division problem so that the divisor would become a whole n

horsena [70]

Devisor is the bottom number
hmm

11.75=11 and 3/4
so times it by 4 to clear denomenator
but do it by top and bottom

23.4/11.75 times 4/4=93.6/47

so times it by 4/4
