help to solve -7 - 3a = 1 - 4a
Answer:
-7 - 3a = 1 – 4a
Step one: Add 4a to -3a
-7 + a = 1
Step two: Add 7 to 1
A = 8
You're done! A=8 for this problem!
Hopefully this helps! Feel free to mark brainliest!
Answer:
[tex]a =8[/tex]
Step-by-step explanation:
[tex]-7 - 3a = 1 - 4a[/tex]
add [tex]3a[/tex] to both sides
[tex]-7 - 3a + 3a = 1 -4a + 3a \\-7 = 1 -a[/tex]
add [tex]-1[/tex] to both sides
[tex]-7 - 1 = 1 - a -1\\-8 = -a[/tex]
multiply both sides by [tex]-1[/tex]
[tex]-8 * (-1) = -a * (-1) \\8 = a[/tex]
An equation of a line with a slope of - 4/5 that passes through the point (5,3)
Answer:
y = -(4/5)x + 7
Step-by-step explanation:
recall that the point-slope form of a linear equation is given as
y - y₁ = m (x - x₁)
in our case, we are given
slope, m = -4/5
and a point (x₁, y₁) = (5,3)
hence we simply substitute these values into the equation
y - y₁ = m (x - x₁)
y - 3 = -(4/5) (x - 5) (we will simplify this to convert to slope-intercept form)
y - 3 = -(4/5) (x) - (-4/5)(5)
y - 3 = -(4/5)x +4 (add 3 to both sides)
y = -(4/5)x +4 +3
y = -(4/5)x + 7
Distance from Starting Point of Spring (inches) 6 2 1 7 Weight on Spring (kilograms) Part A According to the graph, what is the constant of proportionality in kilograms per inch? (Note: This is also called the spring constant. The spring constant is determined by the spring's material and design.)
Answer:
The constant of proportionality is the number of kilograms that will stretch the spring by 1 inch. When y = 1, x = 1/3, so the constant of proportionality in kilograms per inch is 1/3.
the lcm and hcf of 84 and 96 pleasee
Answer: LCM=672; HCF=12
Step-by-step explanation:
LCM=Least Common Multiple
HCF=Highest Common Factor
Factor of 84: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
Factor of 96: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
From the list we can see, the highest common factor between 84 and 96 is 12.
The easiest way to find least common multiple is to time the numbers together and then divide it by their highest common factor.
84×96÷12=672

Which pair of angles are complementary but not adjacent?
Answer:
1 and 3
Step-by-step explanation:
because 5 and 3 have the same value and since 5 and 1 add up to 90 degrees, 3 and 1 must also add up to 90 degree
Angles ∠1 and ∠3 are complementary but not adjacent.
Complementary angles are two angles that add up to 90 degrees.
Adjacent angles are two angles that share a common vertex and a common side.
In the image, angles ∠1 and ∠3 share a common vertex, but they do not share a common side. They are also not adjacent to each other, as there is an angle in between them (angle ∠4).
The measure of angle ∠1 is 48 degrees. The measure of angle ∠3 is 42 degrees. Therefore, angles ∠1 and ∠3 add up to 90 degrees, making them complementary angles.

In a faraway land, there are 72% white people. There are 30% of people have a particular disease. And if you randomly select a person, that person has 20% chance of being white and have the disease. (a) What proportion of students are non-white and who is healthy? (b) Kelly’s race is white, what is the chance that she has this disease? (c) Are the events of being white and having the disease independent events? (d) If you randomly select 10 people, what is the chance that 2 have the disease?
Answer:
Step-by-step explanation:
Let the probability of people being white be P ( W ) and being diseased
be P ( D )
Given
P ( W ) = .72 , P ( D ) = .3
P ( W∩D ) = .2
a )
P ( [tex]W^c[/tex] ∩ [tex]D^c[/tex] ) = P[tex]( WUD)^c[/tex] = 1 - P ( W U D )
= 1 - [ P( W ) + P ( D ) - P ( W ∩ D ) ]
= 1 - ( .72 + .3 - .2 ) = .18
b )
P ( D / W ) = P ( W∩D ) / P(W) = .2 / .72 = .27778
c )
No , because
P ( W∩D ) = .2
p ( W) x P ( D ) = .72 x .3 = .216
so P ( W∩D ) is not equal to P ( W) x P ( D )
d )
We shall apply binomial distribution
chance = 10C₂ x .3² ( 1 - . 3 )⁸
A coat that normally sells for $800 is on sale for $760. By what percent is the original cost of the coat decreased?
Answer:At least around 30%
Step-by-step explanation:
So when looking at the question there is an 800 and 760.
So the question is basically asking you to subtract your numbers. so do "800-760" And u should get 30 :).
Answer:
95
Step-by-step explanation:
800 (the original price) - 100 perecent
760 (the decreased price) - x perecent
We multiply diganol and divided the only number left, so:
760 times 100 divided by 800.
You get 95!

The dimensions on a blueprints indicate that 1 inch equals 3.5 feet. If one wall of a room on the blueprint is 6 inches, whats the actual length of the wall
Answer:
21 feetStep-by-step explanation:
The problem bothers on the dimension of a scaled drawing/prototype
The indications on the blueprint actually represent the scale
that is 1 inch: 3.5 feet
Given that a wall is 6 inches on the blueprint, now, in reality, the actual
length will be 3.5*6= 21 feet
what is a scaled drawing?Usually, the scale is given as a ratio. A drawing, which has been reduced or enlarged or a drawing whose dimensions have been changed to a particular size other than its previous or initial size is a scaled drawing.

Does it matter which two points you start on when calculating slope?
It does not matter which of the two "slope" formulas you use, nor does it matter which point you pick to be your "first" and which you pick to be your "second". The only thing that matters is that you subtract your x-values in the same order as you had subtracted your y-values.
The table shows the number of tickets sold and the profit made at a fundraiser.
Tickets Sold
Profit

6
$54
8
$72
Which describes the relationship between the number of tickets sold and the profit?
Answer:
This is pretty simple, it tells you that two tickets are worth $18, to figure out how much one would cost you just divide 18/2 and that would equal $9. So Your answer would be Each ticket sold yields $9 of profit.
Here, Let, Number of Ticket = x
Sold profit = y
Then, relation would be: 18/2 = 9
y = 9x
In short, Your Answer would be Option B) "Each ticket sold yields $9 of profit"
Hope this helps!
Answer:
its B: Each ticket sold yields $9 of profit.

If that is the case;
[tex]Tota\l Charges = -42\ units[/tex]
We'll get the unit charge when we divide by 7.
This is so because, they all have the same charge.
[tex]Unit\ Charge = -42\ units/7[/tex]
