Answer:
x = 26
Step-by-step explanation:
The sum of the measures of the angles in a triangle is 180°.
(2x)° +50° +(3x)° = 180°
5x +50 = 180 . . . . . . . divide by °, collect terms
x +10 = 36 . . . . . . . . . divide by 5
x = 26 . . . . . . . . . . . . . subtract 10
One number is twelve less than another number. The total of the two numbers is 154. Find both numbers.
Answer:
83 and 71
Step-by-step explanation:
One number is twelve less than the other number
Let the one number be x
Let the other number be x - 12
Since one number is 12 , less than the other number, and the total of the two numbers is 154, then, we'll have
x + x - 12 = 154
2x = 154 + 12
2x = 166
x = 83
Therefore, both numbers would be;
First number = x = 83
Second number = x - 12 = 83 - 12 = 71
The cost of a sweater at a clothing store was $35. The sweater went on sale at a discount of 20% off the original price. What is the sale price of the sweater?
Answer:
$28
Step-by-step explanation:
First, we have to find 20% of 35.
We can do that by multiplying 0.20 by 35. (0.20 x 35)
After multiplying them, we get a product of $7.
Since the sweater went on sale and they took 20% off of the original price, we have to subtract $7 from the original price of $35. (35 - 7)
We can solve that to get us the discounted price of $28

Traveling 10 meters in 1/3 of a second how fast was it going
Answer:
I guess he was traveling 30 meters every second.
(Which is pretty slow to be honest)
Step-by-step explanation:
This question doesn't really make sense since it says it right there he traveled 10 meters in 1/3 of a second. But I'm guessing that you want to find out how many meters per second.
Since 1/3 multiplied by 3 = 1
Then 10 multiplied by 3 = 30.
So, he traveled 30 meters every second.

3. A soccer team spent $216 on 15 new soccer balls. Each ball cost the same.
Part A
Estimate the cost of each soccer ball. Write an equation and solve.
Part B
Find the exact cost of each soccer ball. Compare your answer to your estimate to check for reasonableness.
Answer:
The equation is 216/20= 10.8 so about 11 dollars each
Step-by-step explanation:
Part B 216/ 15= 14.40 14.4 and 10.8 both round down so this awnser is reasonable

Answer:
5
Step-by-step explanation:
Alright so this problem is like that other one i did where line RQx2 is equal to line SU
First we set up an equation
x+3=x-2
because line RQ is only 1/2 of line SU we multiple its side by 2 to get the new equation of
x+3=2x-4
step 1 subtract each side by 2x
-1x+3=-4
step 2 subtract each side by 3
-1x=-7
divide each side by -1
x=7
Next we plug in x (7) so 7-2=5
line RQ=5

The V(t)=1.50(1.17)^t represents the value V (t), in dollars, of a comic book t years after its purchase in 2000. Determine the annual growth rate in the value of the comic book and its value in 2025.
Answer:
Growth rate is 17%
2025 value is $76
Step-by-step explanation:
Here, we want to determine the annual growth rate
The general equation form is;
F = l( 1 + r)^n
where F is the future value
I is the initial value
r is the growth rate
n is the numbering years
To get the growth rate, we simply equate what we have in the bracket to 1 + r
Thus;
1 + r = 1.17
r = 1.17-1
r = 0.17
0.17 is same as 17/100 which is same as 17%
Secondly, we want to get the value of the book in 2025
What we have to do here is to substitute (2025-2000) for t which is 25
We have;
V(t) = 1.50(1.17)^25
V(25) = 75.986 which is approximately 76
We will see that the annual growth rate is of 17%, and in the year 2025, the value will be $75.99.
Exponential growth functions:
A general exponential growth can be written as:
f(x) = A*(1 + r)^x
Where A is the initial value and r is the growth rate. Now we can rewrite our function to get:
V(t) = 1.50*(1 + 0.17)^t
Then you can see that the growth rate is 0.17, or 17% in percentage form (to get it just multiply it bt 100%).
To get the value of the comic book in 2025 you just need to evaluate the function in t = 25 (25 years after the 2000).
V(25) = 1.50*(1 + 0.17)^25 = 75.99
So the value in 2025 is $75.99

g(x) = 2x - 4
h(x)=x+2
Find (g - h)(-4)
=============================================
Work Shown:
(g-h)(x) = g(x) - h(x)
(g-h)(x) = (2x-4) - (x+2)
(g-h)(x) = 2x-4 - x - 2
(g-h)(x) = x - 6
(g-h)(-4) = -4 - 6
(g-h)(-4) = -10
--------------------
An alternative method:
g(x) = 2x-4
g(-4) = 2(-4)-4
g(-4) = -8-4
g(-4) = -12
h(x) = x+2
h(-4) = -4+2
h(-4) = -2
(g-h)(-4) = g(-4) - h(-4)
(g-h)(-4) = -12 - (-2)
(g-h)(-4) = -12 + 2
(g-h)(-4) = -10

Answer:
726 ft
Step-by-step explanation:
The perimeter is the sum of the 4 sides, that is
x + x + 274 + x + 27 + x + 74 = 3279, that is
4x + 375 = 3279 ( subtract 375 from both sides )
4x = 2904 ( divide both sides by 4 )
x = 726
