72kg - 54kg
180kg - xkg
cross multiply
72 · x = 180 · 54
72x = 9720 |divide both sides by 72
x = 135
Answer: 135kg.
Answer:
a)
b)
c)
Step-by-step explanation:
a) The slope / gradient is the coefficient of , so for a) it will be .
C is the y-intercept, so the full equation will be .
b) Again, since the slope is 6, we know the coefficient of will be 6.
Now, we have a point on the line and so far, we know the equation is . The coordinates of the point are (2,-6). So now we substitute the y and x values into the equation in order to find C.
c) To find the gradient we must use the formula .
rise = change in y value
run = change in x value
so, the gradient
Now the equation is
Again, to find C we substitute any of the coordinates into the equation. I will use (-1,3).
so c) is
You do 9=5y-6. And then solve for y. It’s is 3.
Answer:
Option 2: m∠1 = 147°, m∠2 = 80°, m∠3 = 148°
Step-by-step explanation:
Step 1: Consider triangle ABC from the picture attached below.
Lets find angle x
x + 47 + 33 = 180 (because all angles of a triangle are equal to 180°)
x = 100°
Angle x = Angle y = 100° (because vertically opposite angles are equal)
Step 2: Find angle 2
Angle 2 = 180 - angle x (because angle on a straight line is 180°)
Angle 2 = 180 - 100
Angle 2 = 80°
Step 3: Find angle z
48 + y + z = 180° (because all angles of a triangle are equal to 180°)
z = 32°
Angle 3 = 180 - angle z (because angle on a straight line is 180°)
Angle 3 = 180 - 32
Angle 3 = 148°
Step 4: Find angle 1
Angle 1 = 180 - 33 (because angle on a straight line is 180°)
Angle 1 = 147°
Therefore m∠1 = 147°, m∠2 = 80°, m∠3 = 148°
Option 2 is correct
!!
The answer would be B
Because $2.10×7 = 14.7 and $1.85×6 = 11.1 so the new were add 14.7+11.1 Hope this helps
