5.3 to be exact but does it say you round up in the problem? Cause then I’d put 5.5 cups or 6

Solve using substitution -9x+7y=-15 and -8x+y=18

Kipish [7]

Answer:

x=-3, y=-6. (-3, -6).

Step-by-step explanation:

-9x+7y=-15

-8x+y=18

------------------

y=18-(-8x)=18+8x=8x+18

----------------------------------

-9x+7(8x+18)=-15

-9x+56x+126=-15

47x+126=-15

47x=-15-126

47x=-141

x=-141/47

x=-3

-8(-3)+y=18

24+y=18

y=18-24=-6

x=-3, y=-6.

Noor brought 21 sheets of stickers. She gave 1/3 of a sheet to each of the 45 students at recess. She wants to give teachers 1 1

Tamiku [17]

Answer:

$\frac{3}{2}t+15\leq 21$

Step-by-step explanation:

Let t represent the number of teachers.

We have been given that Noor gave 1/3 of a sheet to each of the 45 students at recess.

Let us find the number of sheets given to students by Noor by multiplying the total number of students by the part of sheet given to each student.

$\text{Number of sheets given to 45 students}=45\times \frac{1}{3}$

$\text{Number of sheets given to 45 students}=15$

So, Noor gave 15 sheets to 45 students.

We have been given that Noor wants to give $1\frac{1}{2}=\frac{3}{2}$ sheet to each teachers, so the number of sheets given to t teachers will be $\frac{3}{2}t$ .

As Noor has bought 21 sheets, so the number of sheets given to students and t teachers will be less than or equal to 21.

We can represent this information in an inequality as:

$\frac{3}{2}t+15\leq 21$

Therefore, the inequality $\frac{3}{2}t+15\leq 21$ represents the number of teachers ,t, Noor could give sheets of stickers too.

Plz help me with my hw plz it's proportional relationships and please include the equation

Sphinxa [80]

The constant of proportionality is k = y/x.....k = 40/200 = 1/5

y = mx + b
slope(m) = 1/5
(200,40)...x = 200 and y = 40
now we sub...we r looking for b, the y int

40 = 1/5(200) + b
40 = 40 + b
40 - 40 = b
0 = b

so ur equation is : y = 1/5x

if pop star earned 800
800 = 1/5x
800 * 5 = x
4000 = x

Can someone help me with this.

Ber [7]

Answer:

C

Step-by-step explanation:

The secant- secant angle SPR is half the difference of the intercepted arcs, that is

55° = $\frac{1}{2}$ (RS - QT ) ← multiply both sides by 2

110° = RS - QT = RS - 50° ( add 50° to both sides )

160° = RS → C
