Uhhhhhh ples help me
hoa [83]

Answer:

<u>Approximate values according to picture:</u>

  • a = 1.6, b = 4, c = 5.8

<u>The values of given expressions:</u>

  • a) a + b + c = 1.6 + 4 + 5.8 = 11.4
  • b) c - b + a = 5.8 - 4 + 1.6 = 3.4
  • c) c ÷ a + b = 5.8 ÷ 1.6 + 4 = 3.6 + 4 = 7.6 (3.6 is rounded)

The coordinates of the midpoint of GH are M(-2, 0), and the coordinates of one endpoint are H(4,-4).
Svetlanka [38]

The coordinate of point S from the giving coordinate point is (-8,4)

<h3>Midpoint of coordinates</h3>

The formula for calculating the midpoint of coordinate point is expressed as:

M(x,y) = {(x₁+x₂)/2, (y₁+y₂)/2}

Determine the measure of the coordinate S
-2 = 4+x₂/2

2(-2) = 4+x₂

x₂ = -4-4

x₂ = -8

Similarly

0 = -4+y₂/2

0(2) = -4+y₂

y₂ = 4

Hence the coordinate of point S from the giving coordinate point is (-8,4)

The price of an item has been reduced by 85% . The original price was $45. What is the price of the item now.
Kobotan [32]

Answer:the price for the item now it's 6.75


Step-by-step explanation:

Origin price is 45=100% after reduction comes to 85% =x

X stands for the unknown value of the reduction therefore

45=100%

X=85%

45*.85=100x


After calculation you realised the value of x reduction value it's 38.25


Hence, original price is 45 your less from the value reduced 38.25 therefore the value of the item is 6.75
