Answer:

D) y \geq \frac{-4}{5} +8 .\\\\ y \geq \frac{1}{2} +3.

Step-by-step explanation:

Given  : Graph .

To find : shows the solution to which system of inequalities.

Solution : We have given a graph with two solid lines.

We can see from the given graph line both the line are solid  and shaded up So ,

We will use the greater than sign for shaded up and equal to sign for solid line .

One of line has y - intercept ( where the line cut at y axis ) is 8 and slope is \frac{-4}{5} .

Other line has y - intercept ( where the line cut at y axis ) is 3 and slope is  \frac{1}{2} .

Then inequality is

y \geq \frac{-4}{5} +8 .\\\\ y \geq \frac{1}{2} +3.

Therefore, D) y \geq \frac{-4}{5} +8 .\\\\ y \geq \frac{1}{2} +3.

the length of a rectangle is 5cm longer than twice the length of the width. if the perimeter of the rectangle is 88, what Is the
o-na [289]
Width=x
length=2x+5
perimeter of a rectangle=2(length)+2(width)
We can suggest this equation:
88=2(2x+5)+2x

88=4x+10+2x
6x=88-10
6x=78
x=78/6
x=13

width=x=13
length=2x+5=2(13)+5=26+5=31

Answer: the width would be 13 cm.

£140 is divided between Angad, Nick & June so that Angad gets twice as much as Nick, and Nick gets three times as much as Ju
kramer

Answer:

84

Step-by-step explanation:

Let's say Nick gets amount N, Angad amount A, and June amount J.

Here's what we know:

A+N+J=140

A=2*N

N=3*J.

Let's plug these values in.

N=3*J, so A+N+J=140 can now be A+3*J+J=140.

A=2*N, and N=3*J, so A=2*3*J=6*J. Then, A+3*J+J=140 is now 6*J+3*J+J=140, so 10*J=140 and J=14. N = 3*J=42 and A=2*N=84. Checking this, 14+42+84=140, so we are good to go!

The answer to a,b and c
GuDViN [60]

Answer:

16/45; 4/45; 1125

Step-by-step explanation:

Since you know that 4/9 and 1/5 are used, make them common denominators. So 4/9 would turn into 20/45 and 1/5 would be 9/45. It results in 29/45, but that is the amount spent, so you would subtract 45-29/45, resulting in 16/45. For B, you know that she spent 3/4 of the savings, so you know that 1/4 is not being spent. So use 1/4 multiplied by 16/45 from part A to get 4/45. For C, you know that 4/45 is $100, so I multiplied 45x100 to get 4500 and then divided by 4 to get 4500/4.
