If 35% of a number is 21 and 90% of the same number is 54, find 55% of that number.

inn [45]

Answer:

Step-by-step explanation:

The number is 60:

Divide the amount and decimal of the percentage to be extracted

Case 1

$\frac{21}{0.35} =60$

Case 2

$\frac{54}{0.9} =60$

Now the 55% of this number is:

$60(0.55)=33$

Y=mx+b (-6,-3) and (0,9)

Leno4ka [110]

Answer:

y = 2x + 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 6, - 3) and (x₂, y₂ ) = (0, 9)

m = $\frac{9+3}{0+6}$ = $\frac{12}{6}$ = 2

The line crosses the y- axis at (0, 9) ⇒ b = 9

y = 2x + 9 ← equation of line
