5x - 40 + 3x + 2x + 20 = 180
10x - 20 = 180
10x -20 + 20 = 180 + 20
10x = 200
10x / 10 = 200 / 10
x = 20

A carpenter has a wooden stick that is 84 centimeters long. She cuts off 25% from the end of
the stick. Then she cuts the remaining stick into 6 equal pieces. What is the length of each
piece?
How did you get 63?
Answers
=======================================================
Explanation:
25% = 25/100 = 0.25
25% of 84 = 0.25*84 = 21
So 21 cm has been cut off, leaving 84-21 = 63 cm left over
Or you could say that if 25% has been cut off, then 75% of the stick remains
So, 75% of 84 = 0.75*84 = 63 cm remains.
The remaining length of 63 cm is cut into 6 equal pieces
Each smaller piece is 63/6 = 10.5 cm long
Five years ago you deposited a sum of money into a savings account which has earned $150 in interest. The interest rate for the account is 3% simple interest per year. How much money was originally deposited in the account?
Answers
Answer:
$1000
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year,
then, solving our equation
I = 1000 × 0.03 × 5 = 150
I = $ 150.00
The simple interest accumulated
on a principal of $ 1,000.00
at a rate of 3% per year
for 5 years is $ 150.00.
Find a pair of numbers that have a sum of −3 and a difference of −7.
Answers
Answer:
x = -5 and y = 2
Step-by-step explanation:
You want to start by writing these two equations:
x + y = -3
and
x - y = -7
Then, you want to add the solutions to these two equations, like so:
-3 + -7 = -10
Then, to find the x value, because x > y, divide the answer by two:
-10/2 = -5
So, the x value is -5.
With this information, you can figure out that the y value is 2.
Check the answer:
-5 + 2 = -3
-5 - 2 = -7

Answer : 34
Step-by-step explanation:
Solution,
Given,
base = 16
perpendicular = 30
hypotenuse = ?
Now,
By the formula of Pythagoras Theorem,
h^2 = p^2 + b^2
h^2 = 30^2+16^2
h^2 = 900+256
h = sqrt ( 1156 )
h = 34
Therefore, the value of x (hypotenuse) is 34.

Answers
Answer:
3, 5
Step-by-step explanation:
It is counting up by +2
Answer:
3 and 5
Step-by-step explanation:
The common difference d in an arithmetic sequence is
d = a₂ - a₁ = - 1 - (- 3) = - 1 + 3 = 2
To obtain a term in the sequence add d = 2 to the previous term, that is
a₄ = a₃ + 2 = 1 + 2 = 3
a₅ = a₄ + 2 = 3 + 2 = 5

Mr. Gorelick has gone crazy. He has climbed up to the rafters of the gym 35 feet up and has taken with him a large number of basketballs. Mr. Gorelick can throw a basketball so hard at an angle of declination of 40 degrees that it will knock you out for 17 hours. How far does one of his basketballs travel before hitting someone in the head?
Answers
Answer:
Let the amount of feet be x
Let declination be y
so 35x at a declionation of 40 degrees 35x+40y=feet traveled before hitting the head
35x
40y
35x +40y= 40-y =35x+40-y
and 35x=35-x
35+40=x-y
The ball travels 43ft

Solve for the slope, x- and y-intercepts given the equation below.
7x + 2y = -10
x-intercept:
y-intercept:
Slope:
Answers
Y intercept: (0, -5)
Slope: -7/2
7x+2y=-10
2y=-10-7x
Y=(-7x-10)/2
The slope is the coefficient of x right now, so the slope is -7/2.
The x-intercept’s y is always 0, so we plug that into the equation as y=0.
7x+2y=-10
7x+2(0)=-10
7x+0=-10
X=-10/7
Therefore, the x-intercept is (-10/7,0).
Now, you do the same thing for the y-intercept where x=0 to find your y-intercept.
