Solve 3x+ k = c for x.
Answer:
x=(c-k)/3
Step-by-step explanation:
First, subtract k from both sides of the equation to get: 3x=c-k
Next, divide both sides by 3 to get x by itself=> 3x/3=c-k/3
The threes on the left side cancel, giving you x=(c-k)/3
What is the solution of the system of equations? Y=x-4 and y=-3x
Answer:
(-7,-3)
Step-by-step explanation:
step one) solve one equation for x.
y=-3x
-3x/-3=y/-3
x=(-y/3)
step two) plug in x for the other original problem.
y=x-4
y=(-y/3)-4
step three) solve for y.
y=(-y/3)-4
y+4=(-y/3)-4+4
3*(y+4)=(-y/3)*3
3y+12=-y
(3y+12)-3y=-y-3y
12/-4=-4y/-4
y=-3
step four) plug in -3 for y and solve for x.
y=x-4
-3=x+4
-3-4=x+4-4
-7=x

Answer:
Gradient of KL = 2
Step-by-step explanation:
From the diagram, we are to calculate the gradient of KL. Gradient is salso known as the slope of the line.
Gradient of KL = ΔOK/ΔOL
Given
OK = 2OL
Substitute into the formula
From the diagram, ΔOL = -5
ΔOK = 2ΔOL
ΔOK = 2(-5)
ΔOK = -10
Hence;
Gradient = -10/-5
Gradient of KL = 2
7. Determine the value of x for which ris if
m_1 = 80 - X; and
• m22 90 - 2x.
The given is that r║s while the angles are known.
m∠1 = 80 - x
m∠2 = 90 - 2x
m∠1 = m∠2 because of corresponding angles theorem.
So,
m∠1 = m∠2
80 - x = 90 - 2x
- x = 90 - 80 - 2x
- x = 10 - 2x
- x + 2x = 10
x = 10
The value of x is 10
The volume of a cone is represented by the formula V = 1 T?n. If the volume of a cone is 30rt and the height is 2.5, what is the radius of the cone?
Answer:
radius is 3.38cm
Step-by-step explanation:
Note: the volume of a cone is given as
[tex]V= 1/3 \pi r^2 h[/tex]
Step one:
Given Information
volume= 30cm^3
height= 2.5cm
Required
The radius of the cone
Step two:
substituting our data into the expression for the volume of a cone we can then solve for the radius r
[tex]30=1/3 *3.142*r^2 * 2.5\\\\30=1/3*7.855r^2\\\\30=2.62r^2\\\\[/tex]
divide both sides by 2.62
[tex]30/2.62= r^2\\\\11.45= r^2\\\\r=\sqrt{11.45} \\\\r=3.38cm[/tex]

Bill is planning to drive 1,000 miles to visit his family. If he plans to drive 250 miles per day, which of the
following represents the remaining distance d, in miles, that Bill will have to drive to reach his family after
driving for n days?
А
d = 1,000 + 250n
B d = 1,000n - 250
d = 250n - 1,000
D d = 1,000 - 250n
30 men repair a road in 56 days by working 6 hours daily. in how many days 45 men will repair same road by working 7 hours daily?
Answer:
Case1:
Men : 30
Work : 1
Time (day×hr): 56×6 = 336 hr.
Case2:
Men : let it be m men.
Work: 1
Time: 45×7 = 315 hr.
Work being constant in both cases, men and time are in inverse proportion i.e, more men take less time.
Product of men and time is constant in both cases.
Therefore, 30×336=m×315
Or, 30×336/315 = m
Or, m = 32.
Hence, required number of men is 32.

Two cards are drawn at random from a standard deck of cards. What is the probability of not
drawing a 10 or a Queen? Round the answer to the nearest hundredth of a percent.
Answer:
0.85
Step-by-step explanation:
A standard deck of cards has 52 cards. There are 4 10s and 4 Queens in the deck. There 8 cards that are 10s or Queens.
52 - 8 = 44
There are 44 out of 52 cards that are not 10s or Queens.
p(not 10 or Queen) = 44/52 = 0.85
Answer: 0.85

Chelsea wants to join a fitness club. The fitness club charges and initial membership fee of $30 and a monthly fee of $10.50. She has $114 to spend on a membership at the fitness club. Right and solve an equation to find the number of months Chelsea can be a member of the fitness club
Answer:
She can be a member for 8 months
Step-by-step explanation:
Let x be the number of months
30 + 10.5(x) = 114
30 + 10.5x = 114
10.5x = 114-30
10.5x = 84
x = 84/10.5
x = 8 mints

What is the equation of this parabola?
Answer:
y = - x² + 4
Step-by-step explanation:
The equation of a parabola whose vertex is on the y- axis is
y = ax² + c
where a is a multiplier and c is the y- intercept
• If a > 0 then minimum vertex
• If a < 0 then maximum vertex
Here vertex is a max, thus a = - 1 and c = 4
Then equation of parabola is
y = - x² + 4
