Sanjeev ate 1/6 of cake he gave to his frend the remainder 1/5 how much did he keep

liq [111]

Step-by-step explanation:

$= 1 - ( \frac{1}{6} + \frac{1}{5} )$

$= 1 - ( \frac{5}{30} + \frac{6}{30} )$

$= 1 - \frac{11}{30}$

$= \frac{30}{30} - \frac{11}{30}$

$= \frac{19}{30}$

So, he keeps $\frac{19}{30}$

The equation y= 1/2 x +4 is graphed below.which equation would intersect this line at (4, 6)?

Anton [14]

Answer:

we have the equation y = (1/2)*x + 4.

now, any equation that passes through the point (4, 6) will intersect this line, so if we have an equation f(x), we must see if:

f(4) = 6.

if f(4) = 6, then f(x) intersects the equation y = (1/2)*x + 4 in the point (4, 6).

If we want to construct f(x), an easy example can be:

f(x) = y = k*x.

such that:

6 = k*4

k = 6/4 = 3/2.

then the function

f(x) = y= (3/2)*x intersects the equation y = (1/2)*x + 4 in the point (4, 6)

kati45 [8]

Answer:

$m=-7$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from chart.

Point (39, 36)

Point (40, 29)

Step 2: Find slope m

Substitute: $m=\frac{29-36}{40-39}$
Subtract: $m=\frac{-7}{1}$
Divide: $m=-7$
