Answer:
20 minutes
Step-by-step explanation:
Plan A
C = 40 + 0.05m
Plan B
C = 0.25m
we want to find the number of minutes m such that the two plan cost the same.
Hence
40 + 0.05m = 0.25m
40 = 0.20 m
m = 40/ 0.20
m = 400 / 2
m = 20 minutes.

X+2y, if X=-2 and Y=4
Answer:
6
Step-by-step explanation:
X=-2
Y=4
X+2y
= -2 + 2(4)
= -2 + 8
= 6
the answer is:
6
because:
X=-2
Y=4
X+2y
= -2 + 2(4)
= -2 + 8

Answer:
2a. (360x +495)/(8x +11) = 45
2b. 2((8x+11) +45) = 16x +112
Step-by-step explanation:
a) The area is the product of length and width.
A = LW
We are given ...
W = 8x +11
A = 360x +495
The value of length can be found by solving for L:
L = A/W
L = (360x +495)/(8x +11)
The long-division solution to this is shown in the attachment.
L = 45 . . . . simplified expression for length
__
b) The perimeter of the tank is twice the sum of length and width:
P = 2(L +W)
Substituting the values for L and W, this is ..
P = 2(45 +(8x +11)) . . . . expression for length of edge seal
P = 2(8x +56)
P = 16x + 112 . . . . . . simplified expression for seal length
Sandi got 1/1/4 pounds of gummy worms if she left the store with 3 pounds of gunmys worms and skittles ,how many pounds of skittles did she get
Answer:
1 3/4 lbs of skittles
Step-by-step explanation:
Easy way: 3lbs - 1 1/4lbs = 1 3/4lbs
Complex way:
(I'm assuming "1/1/4" means "1 1/4")
This is simply ~Subtraction~
The total is 3lbs(t) and 1 1/4 of that 3lbs is gummy worms(g). What is left of the 3lbs is skittles(s).
So we need to know what added to 1 1/4 equals 3.
Equation: t= 1 1/4 + s
Equation: t= 1 1/4 + s
We can replace (t) with 3 because we know this variable.
1. 3= 1 1/4 + s
To isolate the variable (s) we need to subtract 1 1/4 on both sides of the equation
2. 3(- 1 1/4)= 1 1/4(- 1 1/4) + s
The right side cancels out = 0 and the left = 1 3/4
3. 1 3/4= s
Flip it around for the traditional view
4. s = 1 3/4
In word form: Skittles equal 1 3/4 (don't forget to add lbs or pounds back into the final answer)

-m/3 = -4
-m = -4*3
-m = -12
m=12

70° ? 127° 146° Can I get some help with this?
Answer:
93 degrees
Step-by-step explanation:
First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,
180-127= 53.
180-146=34.
Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.
x=93
Now, just flip the angle around and "?" = 93 degrees.
Answer: 93 degrees
===========================================================
Explanation:
Let x be the question mark angle we want to find.
Let y be adjacent to the 127 degree angle
Let z be adjacent to the 146 degree angle.
Refer to the diagram below.
Note that in the diagram, I have a second copy of 'x' because the two x angles are vertical angles. Vertical angles are always congruent.
Let's find angle y
127+y = 180
y = 180-127
y = 53
Do the same for angle z
z+146 = 180
z = 180-146
z = 34
Then notice how,
x+y+z = 180
x+53+34
x+87 = 180
x = 180-87
x = 93

You are going on a long trip and want to calculate your Miles per gallon. When you start your trip your odometer read 95842 miles. At the end of your trip your odometer reads 95975 miles. You started with a full tank and to return to a full tank you put in 7 gallons of gas total. What is your miles per gallon?
Answer:
19 miles per gallon
Step-by-step explanation:
95975 - 95842 = 133
133 divided by 7 = 19
If a + b = 20 and ab = 75, find the value of a? + b2.
Answer:
a² + b² = 250
Step-by-step explanation:
Given
a + b = 20 ( square both sides )
(a + b)² = 20² , that is
a² + b² + 2ab = 400 ( substitute ab = 75 )
a² + b² + 2(75) = 400
a² + b² + 150 = 400 ( subtract 150 from both sides )
a² + b² = 250
