Answer:

x = 4

Step-by-step explanation:

By BPT

$\frac{10 - x}{x} = \frac{3}{2} \\ \\ 2(10 - x) = 3x \\ \\ 20 - 2x = 3x \\ \\ 20 = 2x + 3x \\ \\ 20 = 5x \\ \\ x = \frac{20}{5} \\ \\ x = 4$

In Carna's desk drawer, there are 16 paper clips and 20 elastic bands. In Noelia's office supply tray, there are 10 paper clips

Nimfa-mama [501]

Answer:

Carna has a lower ratio of paper clips to elastic bands

0.2

Step-by-step explanation:

step one

given data

In Carna's desk drawer

number of paper clips 16

number of elastic band= 20

ratio of paper clips to elastic bands

16:20= 1/5 =0.2

Noelia's office supply tray

number of paper clips 10

number of elastic band= 13

ratio of paper clips to elastic bands

10:13= 0.76

Carna has a lower ratio of paper clips to elastic bands

0.2

‼️‼️solve by substitution {-r+T=5 , -2r+T=4. all these problems w work shown (along w the other problems i posted) r due in the

Luden [163]

Answer:

#4: (r,t) = (1,6) #5: (x, y) = (- $\frac{1}{2}$ ,4) #6: (x, y) = (3, 5) #7: (p, r) = (10, $\frac{14}{3}$ )

Step-by-step explanation:

#4:

Solve for t.

t = 5 + r

Substitute the given value of t into equation

-2r + 5 + r = 4

Solve for r

r = 1

substitute the given value of r into equation

t = 5 + 1

solve for t

t = 6

solution is ordered pair (r, t) = (1,6)

#5:

Solve for y.

y = 2 - 4x

Substitute the given value of y into equation

2x - (2- 4x) = -5

Solve for x

x = - $\frac{1}{2}$

substitute the given value of x into equation

y = 2 - 4x (- $\frac{1}{2}$ )

solve for y

y = 4

solution is ordered pair (x, y) = (- $\frac{1}{2}$ ,4)

#6:

Solve for x

x = -12 + 3y

Substitute the given value of x into equation

2 (-12 + 3y) + y = 11

Solve for y

y = 5

substitute the given value of y into equation

x = -12 + 3 x 5

solve for x

x = 3

solution is ordered pair (x, y) = (3, 5)

Solve for r

r = $\frac{14}{3}$

Substitute the given value of into equation

-2p + 3x $\frac{14}{3}$ = -6

Solve for p

p = 10

solution is ordered pair (p, r) = (10, $\frac{14}{3}$ )

Between emma and dave, we have 7/10ths of the money

3x + 2x = 7/10

5x = 7/10

x=(7/10)/5

x= 14/100

Dave will get 28/100 or 7/25ths

Check : 30/100 Colin
42/100 Emma
