Craig grades 9 test every 22 minutes if craig has 63 test to grade how long will it take him

The answer would be 156 min or 2h and 32 min, the way you would find it is by dividing 63 by 9 and that would get you 7, then you multiply 7 by 22 resulting in 156, then you would simplify it down to 2hours and 32 minutes.

The New Orleans Saints scored 7 fewer points than twice the points scored by the Pittsburgh Steelers. The two teams together sco

zalisa [80]

Answer:

(m) + 2 (m) - 7 = 32 is the needed expression.

Points scored by Pittsburgh Steelers = 13

Points scored by New Orleans Saints = 19

Step-by-step explanation:

Let us assume the points scored by Pittsburgh Steelers = m

So, the Points scored by New Orleans Saints

= 2 (Points scored by Pittsburgh Steelers ) - 7

= 2 (m) - 7

Also,the total points scored by both teams = 32

So the points scored by( New Orleans Saints + Pittsburgh Steelers) = 32

⇒ (m) + 2 (m) - 7 = 32

or, 3 m = 32 + 7 = 39

⇒ m = 39/ 3 = 13, or m = 13

So, the points cored by Pittsburgh Steelers = m = 13

and the points scored by New Orleans Saints = 2m - 17

= 2(13) - 7 = 19

I will set it up and you finish.

Let a = adult

Let s = students

s = 2a

Here is your system of equations:

a + s = 366
s = 2a

Take it from here.

Solve the equation. Then check your solution. – two-fifths + a = One-fifth a. Three-fifths c. StartFraction 3 Over 10 EndFractio

VLD [36.1K]

Answer:

a = Negative one-fifth

Step-by-step explanation:

The given equation is :

$\dfrac{2}{5}+a=\dfrac{1}{5}$

We need to find the value of a.

Subtract 2/5 from both sides.

$\dfrac{2}{5}+a-\dfrac{2}{5}=\dfrac{1}{5}-\dfrac{2}{5}\\\\a=\frac{1}{5}-\frac{2}{5}\\\\a=\dfrac{-1}{5}$

So, the correct answer is Negative one-fifth. Hence, the correct option is (b).

Which linear function represents the line given by the point-slope equation y + 7 = –2/3(x + 6)?a. f(x) = –2/3x – 11b. f(x) = –2

Pavel [41]

Answer:

option C

$y=\frac{-2}{3}x-11$

Step-by-step explanation:

The point slope equation of a line is given by

$y-y_1=m(x-x_1)$

Where m is the slope and (x1,y1) is the point on the point

$y + 7 =\frac{-2}{3}(x + 6)$

We need to write the equation in y=mx+b form

multiply -2/3 inside the parenthesis

$y + 7 =\frac{-2}{3}x-4$

Subtract 7 from both sides

$y=\frac{-2}{3}x-11$
