Multiply a two-digit number by a single-digit number and has exercises on that. Or multiply a three or four-digit number, and has lots of exercises on that.
Xy = 450
y = x/2 => x=2y substituted inside first equation will get 2y*y=450 => y^2 = 225
y=15 because 15*15=225
x=2y so x=2*15 = 30
x=30
y=15
hope this will help you
Answer:
(-2.5,1)
Step-by-step explanation:
Let the point be (m, n). Using section formula we have
m=(5*(-1)+3*(-5))/(5+3)=-20/8=-2.5
n=(5*(7)+3*(-9))/(5+3)=1
Answer:
x = 35, y = 26.5
Step-by-step explanation:
x = 35 ( Alternate angles are congruent )
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2y - 10 + 35 + 102 = 180, that is
2y + 127 = 180 ( subtract 127 from both sides )
2y = 53 ( divide both sides by 2 )
y = 26.5
