Given parameters:
1. [tex]-\frac{7}{8} + \frac{1}{4}[/tex]
[tex]-\frac{7}{8} + \frac{1}{4}[/tex]; find the LCM = 8
= [tex]\frac{-7 + 2 }{8}[/tex]
= [tex]\frac{-5}{8}[/tex]
2. [tex]-\frac{12}{5} + 15.3[/tex]
Make the fraction decimal;
[tex]-\frac{12}{5}[/tex] = -2.4
So;
-2.4 + 15.3 = 12.9

-28 = 5y - 8
Answer:
y=-4
Step-by-step explanation:
Hope this helps :)
Answer:
y = -4
Step-by-step explanation:
Assuming we are solving for y, start by isolating the variable:
-28 = 5y - 8
-20 = 5y (Added 8 on both sides.)
-4 = y (Divided 5 on both sides.)
What conclusion can be made?
Answer: B) The value of k must be between 1 and 2
The function f(x) has a restricted domain [1, 2] which means [tex]1 \le x \le 2[/tex]
So we can only pick inputs in that interval. If x = k, then [tex]1 \le k \le 2[/tex]

What is the slope of the line that passes through points (-6,-7) and (-24,-7) . Write your answer in the simplest form
Answer:
The slope of the line passing through both points is 0
Step-by-step explanation:
Mathematically, we can calculate the slope as follows;
m = (y2-y1)/(x2-x1)
where (x1,y1) = (-6,-7)
(x2,y2) = (-24,-7)
Thus m = (-7 -(-7))/(-24 + 6) = 0/18 = 0
The slope of both is 0
Steven has £1100.
He pays £530 for a new TV.
His mortgage payment is £480.
How much money does he have left after paying for the TV and
paying his mortgage?
Answer:
£90
Step-by-step explanation:
Total money=£1100
Cost of new tv=£530
Mortage payment=£480
Therefore total money left =1100-(530+480)
=1100-1010=£90
A store sells a 33-pound bag of oranges for \$ 3.60$3.60 and a 55-pound bag of oranges for \$ 5.25$5.25. What is the difference between the price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges?
Answer:
0.01364
Step-by-step explanation:
It is given that,
A store sells a 33-pound bag of oranges for $3.60 and a 55-pound bag of oranges for $5.25.
Price per pound of 33 pound bag is 3.60/33 = 0.10909 price per pound
Price per pound of 55 pound bag of oranges is 5.25/55 = 0.09545 price per pound
Difference between price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges is :
D = 0.10909 - 0.09545
D = 0.01364
Therefore, this is the required solution.
If <3=50, then find the rest of the angles
d)) The ratio of the monthly income and expenditure of Sunayana is 5 : 3. If she
increases her income by Rs 5,000 and decreases the expenditure by Rs 3,000, the
new ratio becomes 5:2. Find her income and expenditure.
Answer:
Sunayana's income is ₹25000 and expenditures are ₹15000.
Step-by-step explanation:
Let i denote the monthly income and e denote the expenditures.
We know that the ratio of the monthly income to expenditure is 5:3. So, we can write the following proportion:
[tex]\displaystyle \frac{i}{e}=\frac{5}{3}[/tex]
Let's multiply both sides by e. This yields:
[tex]\displaystyle i=\frac{5}{3}e[/tex]
We know that when the income is increased by 5000 and the expenditures are decreased by 3000, the new ratio is 5:2. So, we can write the following proportion:
[tex]\displaystyle \frac{i+5000}{e-3000}=\frac{5}{2}[/tex]
Let's multiply both sides by [tex](e-3000)[/tex]:
[tex]\displaystyle i+5000=\frac{5}{2}(e-3000)[/tex]
Since we know that [tex]i=\frac{5}{3}e[/tex], substitute:
[tex]\displaystyle \frac{5}{3}e+5000=\frac{5}{2}(e-3000)[/tex]
So, let's solve for the expenditures. Distribute the right:
[tex]\displaystyle \frac{5}{3}e+5000=\frac{5}{2}e-7500[/tex]
Subtract [tex]\frac{5}{2}e[/tex] from both sides:
[tex]\displaystyle -\frac{5}{6}e+5000=-7500[/tex]
Subtract 5000 from both sides:
[tex]\displaystyle -\frac{5}{6}e=-12500[/tex]
Multiply both sides by -6/5. So, the expenditures are:
[tex]e=\text{Rs }15000[/tex]
We can use the original ratio to find Sunayana's income:
[tex]\displaystyle i=\frac{5}{3}e[/tex]
Substitute 15000 for e. Evaluate:
[tex]\displaystyle i=\frac{5}{3}(15000)=\text{Rs }25000[/tex]
So, Sunayana's income is ₹25000 and expenditures are ₹15000.
And we're done!
Answer: Income = 25000, Expenditures = 15000
Step-by-step explanation:
A ratio of 5:3 can also be written in fraction form as [tex]\dfrac{5}{3}[/tex] (which is in simplified format from [tex]\dfrac{5x}{3x}[/tex]).
Adding 5000 to 5x results in 5x + 5000
Subtracting 3000 from 3x results in 3x - 3000
--> [tex]\dfrac{5x+5000}{3x-3000}[/tex]
The new ratio of 5:2 can be written in simplified fraction form of [tex]\dfrac{5}{2}[/tex].
Set the fractions equal to each. Then cross multiply and solve for x.
[tex]\dfrac{5x+5000}{3x-3000}=\dfrac{5}{2}[/tex]
5(3x - 3000) = 2(5x + 5000) Cross multiplied
15x - 15000 = 10x + 10000 Distributed
5x - 15000 = 10000 Subtracted 0x from both sides
5x = 25000 Added 15000 to both sides
x = 5000 Divided 5 from both sides
The original ratio of 5 : 3 --> 5x:3x
where 5x is the income and 3x is the expenditures results in:
income = 5x expenditures = 3x
= 5(5000) = 3(5000)
= 25000 = 15000

What is the rate of change of this table?
Answer:
- 6
Step-by-step explanation:
The rate of change of the values is the slope m
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 32) and (x₂, y₂ ) = (0, 20) ← 2 ordered pairs from the table
m = [tex]\frac{20-32}{0+2}[/tex] = [tex]\frac{-12}{2}[/tex] = - 6 ← rate of change

Solve the equation for a
5n + 34 = -2(1 - 7n)
a equals
Answer:
n = 4
Step-by-step explanation:
Where's a or did you mean n?
Answer:
n=4
Step-by-step explanation:
5n+34=-2(1-7n)
1. So first expand.
5n+34=−2+14n
2 Regroup terms.
5n+34=14n−2
3 Subtract 5n from both sides.
34=14n−2−5n
4 Simplify 14n-2-5n to 9n-2.
34=9n−2
5 Add 22 to both sides.
34+2=9n
6 Simplify 34+2 to 36.
36=9n
7 Divide both sides by 9.
36/9=9
8 Simplify 36/9 to 4
4=n
9 Switch sides.
n=4

Answer:
It's a line parallel to the y-axis
Step-by-step explanation:
Note that the similar x value in both coordinates.
Then it's a line drawn parallel to the y-axis
Therefore, the slope is infinite as it makes a right angle with the x-axis.

Use the distributive property to write an equivalent expression -3(-5x+7)
Answer:
15x - 21
Step-by-step explanation:
-3(-5x+7)
you sidtribute the 3 to both numbers by multiplying both the -5 and the 7 by -3
-3 x -5x = 15x (remember, a negative times a negative equals a positive)
-3 x 7 = -21 (A negative times a positive equals a negative)
15x - 21

You and your friend each purchase an equal number n of magazines. Your magazines cost $1.50 each and your friend's magazines cost $2 each. The total cost for you and your friend is $10.50. Write and solve an equation to find the number of magazines you purchased.
Given:
You and your friend each purchase an equal number n of magazines.
Your magazines cost = $1.50 each
Your friend's magazines cost = $2 each
Total cost = $10.50
To find:
The equation to find number of magazines you purchased.
Solution:
Your magazines cost = $1.50 each
Your friend's magazines cost = $2 each
Number of magazines purchased by you and your friend = n
Total cost = [tex]1.50n+2n[/tex]
It is given that total cost is $10.50.
[tex]1.50n+2n=10.50[/tex]
[tex]3.50n=10.50[/tex]
Divide both sides by 3.50.
[tex]n=\dfrac{10.50}{3.50}[/tex]
[tex]n=3[/tex]
Therefore, required equation is [tex]1.50n+2n=10.50[/tex] and the number of magazines purchased by you is 3.
