Please help me Solve -2a -5>3

worty [1.4K]

Answer:

a < -4

Step-by-step explanation:

Step 1: Write out inequality

-2a - 5 > 3

Step 2: Add 5 to both sides

-2a > 8

Step 3: Divide both sides by -2

a < -4

Here, we can see that any value of a less than -4 works. So a could be -124 or -5, or even -1271293587923857 and it would work.

SVEN [57.7K]

Cost of painting is GHe 109,320

Given:

Floor measure = 15 m by 8 m

Cost of carpeting = GHe 890 per square meter

Total cost of painting and carpeting = GHe 216,120

Find:

Cost of painting

Computation:

Area of floor = 15 × 8

Area of floor = 120 square meter

Cost of carpeting = 120 × 890

Cost of carpeting = GHe 106,800

Cost of painting = Total cost of painting and carpeting - Cost of carpeting

Cost of painting = 216,120 - 106,800

Cost of painting = GHe 109,320

The figure shown is an equilateral triangle. Calculate the length of each side and give your answer in cm.

cricket20 [7]

Given at you have an equilateral triangle, all sides have the same length.

Therefore,
First side 2x-7 = Second side x+y-9 = Third side y+5

Let us look at the second and third sides for now:
x+y-9 = y+5
x = y+5 - (y-9)
x = y-y+5+9
x = 14

Then we look at equating the first and third sides:
2x-7 = y+5
y = 2x-7-5

Substitute x =14 in the equation above:
y = 2(14)-7-5
= 28-7-5
= 21-5
= 16

The length of the third side is:
y+5 = 16 +5 = 21

Given that the length of each sides are the same in an equilateral triangle, all sides have the length 21cm.
