Step-by-step explanation:
you just double it
Answer:
The sum of the three inside angles of a triangle need to equal 180 degrees.
X = 180 - 79 - 73
x = 28 degrees
<span>1. Make y the subject
a) 4y=12x+18
y = 3x + 4.5
b) 2x=7-3y
3y = -2x + 7
y = -2/3x + 7/3
2.
a) what is the equation of the line which passes through both (-2,-4) and (6,16)
slope = (16 + 4)/(6 +2) = 20/8 = 2.5
y = mx + b
-4 =2.5(-2) +b
-4 = -5 +b
b = 1
equation
y = 2.5x + 1
b) what is the equation of the line perpendicular to y= 1/2X + 7 passing through point (3,9)
</span>y= 1/2X + 7
slope = 1/2
slope of line perpendicular = -2
passing through point (3,9)
y = mx + b
9 = -2 (3) + b
b = 15
equation
y = -2x + 15
Answer:
3 1/3 gum balls per friend
Step-by-step explanation:
Packs of gum balls Pete has = 4
Each pack = 5 gum balls
Total gum balls Pete has = Number of packs of gum balls × Number of gum balls in each pack
= 4 × 5
= 20 gum balls
Pete gives the same number of gum balls to 6 friends.
Each friend gets = Total gum balls / number of friends
= 20 gum balls / 6 friends
= 3 2/6 gum balls per friend
= 3 1/3 gum balls per friend
