Debra spends 42 minutes each day driving to work. About how many minutes does she spend driving to work each month?
Answer:
given,
time spent each day for driving to work = 42 mins time spent for driving work each month ( m ) = ?
we know ,
1 month is equal to 12 days
so,
m = 42× 12
= 504
hence, Debra spends 504 minutes driving each month.

29 + 9x ≤ 65
solve for x
Answer:
x <= 4
Step-by-step explanation:
29+9x<65
-29. -29
9x<36
divide both sides by 9
x less than or equal to 4
Answer:
x ≤ 4
Step-by-step explanation:
29 + 9x ≤ 65
subtract 29 from both sides
29 - 29 + 9x ≤ 65 - 29
9x ≤ 36
divide both sides by 9
9x / 9 = x and 36 / 9 = 4
we're left with x ≤ 4

-5(x + 6) = -(5x-9)
Please give me answer!
Answer:
There is no solution to this equation.
Hope this helps :)
Answer:
no solution.
Step-by-step explanation:
carry the -5 and - sign and multiply the numbers within the () signs. so - 5×x and -5×6. which is -5x + -30. the other side will be -5x + 9. so then if you take away the -5x your left with -30 = 9 which is impossible.

A) assuming the car is traveling at a constant speed, at what rate is the car traveling?
The acceleration of a car that travels in a straight line at a constant speed of 100 km/h is zero. Average acceleration = (change in velocity)/(time it takes). Since the car's change in velocity is zero, its acceleration is zero.
You start at (-4, -1). You move up 2 units and right 6 units. Where do you end?

X and Y become positive by going up and right
Answer:
(2, 1 )
Step-by-step explanation:
A move of 2 units up in the positive y- directions means adding 2 to the y- coordinate.
A move right of 6 units in the positive x- direction means adding 6 to the x- coordinate.
(- 4, - 1 ) → (- 4 + 6, - 1 + 2 ) → (2, 1 )

Find the area of the circle. Round to the nearest
tenth. Do not write units of measure.
Find the area of each circle. Use 3.14 for pi.
Answer:
452.16 cm
28.26 m
113.04 km
Step-by-step explanation:
The equation for area is r^2 π
where you square the radius and multiply by 3.14 or pi or how many digits you need to use.
For example, on the first question, you multiply the radius (12) by itself or square it to get 144.
Then you multiply 144 by 3.14 to get your first answer.

find all complex solutions of 13x^2-5x+1=0
btw it doesn’t let me do the +- sign
Answer:
Step-by-step explanation:
You can make it by using division +/-. The keystrokes are
+
/
-
a = 13
b = -5
c = 1
x = [-(-5) +/- sqrt( (-5)^2 - 4*13*1) )] / 2
x = [ 5 +/- sqrt( 25 - 52) ] / 2
x = [ 5 +/- sqrt(-27)]/2
x = [5 +/- 3 sqrt(3)i ] / 2
x = 5/2 +/- 3/2 * sqrt(3) i
So x1 = 2.5 + 1.5 sqrt(3)i or
x2 = 2.5 - 1.5 sqrt(3)i

Answer:

Step-by-step explanation:
3 x 1.8 = 5.4 (m2)

Answer:
1) 5.44, 2) 3.9
Step-by-step explanation:
1) a/b + 2b - a^2 when a = 1.4 and b = 0.2
plug in the values:
1.4/0.2 + 2(0.2) - (1.4)^2 = 7 + 0.4 - 1.96 = 5.44
2) a[b-2c]^3 - d/e when a = 2, b = -0.75, c = -1, d = 0, e = -12 5/7 (rewritten to -89/7 = 12.71)
again, plug in the values:
2[-0.75-2(-1)]^3 - 0/12.71 = 2[1.25]^3 - 0 = 2[1.95] = 3.9

Morgan Office Supply sells 8 reams of Brand X paper for $40 and 4 reams of Brand Y paper for $19. What is the cost savings per ream of paper for the cheapest brand?
Answer:
$0.25 per ream
Step-by-step explanation:
The costs per ream are ...
X: $40/(8 reams) = $5/ream
Y: $19/(4 reams) = $4.75/ream
The savings per ream is $5.00 -4.75 = $0.25 for the cheapest brand.
