Which system of linear equations can be solved using equation [x y] = [1/4 3/4 1 2] [28 -12]
-8x+3y=28
4x-y=-12
Step-by-step explanation:
Let's find x and y from matrices and then check for this systems.
[tex]\left \[[ {{\frac{1}{4} *28-\frac{3}{4}-12 } \atop {1*28-2*12}} \right.][/tex]
Simplify, so we got

So x=-2
y=4
So we need to put those values and check system.

A sporting goods company near the beach rents bicycles for $10 plus &5 per hour. Write an equation in
slope-intercept form that shows the total cost, y, of renting a bicycle for x hours. How much would it cost
Emily to rent a bicycle for 6 hours?
Answer:
It will cost Emily $40 to rent the bike for 6 hours.
Step-by-step explanation:
SOLUTION:
Total cost equals = (cost per hour × number of hours) + initial bike cost.
Let, y be total cost and x = renting a bicycle for x hours.
y=5x+10
To calculate Emily's cost for 6 hours, let x=6.
y=5(6)+10
y=30+10
y=40
It will cost Emily $40 to rent the bike for 6 hours.

Of 20 people who drink coffe 12 don’t put sugar what fraction would represent the people that use sugar in there coffee
Answer:
Fraction 8/20
Step-by-step explanation:
So only 12 people don't use sugar so if we were to put a fraction for people who don't put sugar then it would be.
12/20
The 20 stands about how many people their are and the 12 stands for how many people don't put sugar.
So now we are supposed ot do peope who put sugar so it would look like this
8/20
How I got the 8 is that I took the 20 people and subtrack it with the people who don't get sugar which is 8 and 8 people use sugar so theirs our answers.
8/20
2.7% of X equals 50,000. what is X?
don't give fake answers just for points YOU WILL BE REPORTED
Answer:
x = 1851851.851....
Step-by-step explanation:
Given statement:
2.7% of x equals 50,000.
When we convert the statement into an equation, we get;
⇒ 2.7% × x = 50,000
A percentage is always written as (Percent)/100 in fraction form. Thus;
⇒ 2.7/100 × x = 50,000
Using cross multiplication:
⇒ 2.7 × x = 50,000 × 100⇒ 2.7 × x = 5,000,000To determine the value of x, we need to isolate it. This can be done by dividing the cooeficient of x both sides.
Divide both sides by 2.7
⇒ (2.7 × x)/2.7 = 5,000,000/2.7⇒ x = 1851851.851....Answer:
Percent in decimal form:
[tex]\sf 2.7\% = \dfrac{2.7}{100} = 0.027[/tex]
Therefore:
27% of X = 50000
[tex]\sf \implies 0.027 \cdot X=50000[/tex]
[tex]\sf \implies X=\dfrac{50000}{0.027}[/tex]
[tex]\sf \implies X=\dfrac{50000 \times 1000}{0.027 \times 1000}[/tex]
[tex]\sf \implies X=\dfrac{50,000,000}{27}\quad \textsf{(as a fraction)}[/tex]
[tex]\sf \implies X=1,851,852\quad \textsf{(nearest whole number)}[/tex]

jack is a single-father of two children. he earns a net income of $3000 each month and is considering getting a second job to make end meet. his grocery shopping methods are erratic with random tips throughout the week. he typically spends $600 a month on food. what percent of his bet income is going toward food? should he consider budgeting more or less for groceries
Answer:20%
Step-by-step explanation:
Solution for 600 is what percent of 3000:
600:3000*100 =
( 600*100):3000 =
60000:3000 = 20
Now we have: 600 is what percent of 3000 = 20
Question: 600 is what percent of 3000?
Percentage solution with steps:
Step 1: We make the assumption that 3000 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that $100%=3000.
Step 4: In the same vein, x%=600.
Step 5: This gives us a pair of simple equations:
$100%=3000(1).
x%=600(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% / %=3000/600
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100%=600/3000
--->=20%
Therefore, $600 is $20% of $3000.
you ordered 7.48 worth of food at sonic before tax . if tax is 7% , how much tax will you pay and whats the total .
Answer:
Tax = $0.5236
Total = $8
Step-by-step explanation:
$7.48 * 0.07(tax rate) = $0.5236
$0.5236 is the add-on tax you will pay at a rate of 7%
Simply add $0.5236 to your bill before tax of $7.48 to find your total of $8.0036
8.0036 is too low to round to a monetary value, so in total you would pay
approximately $8

Which statements are true about x? Select three options.
The element x is an illustration of sets and the true statements about x are: x ∈ B ∪ C, x ∈ B ∩ C and x ∈ A ∪ C
How to determine the true statements?From the Venn diagram in the complete question, we have the following highlights:
Element x is present in set BElement x is present in set CThe above means that:
The element is a common element in the intersection of sets B & C and in the union of sets B & C.
This is represented as:
x ∈ B ∪ C and x ∈ B ∩ C
Also, we can say that the element is a common element in the union of sets A & C and in the union of sets A & B.
This is represented as:
x ∈ A ∪ B and x ∈ A ∪ C
Hence, the true statements about x are: x ∈ B ∪ C, x ∈ B ∩ C and x ∈ A ∪ C

Caroline was out at a restaurant for dinner when the bill came. Her dinner came to $22. After adding in a tip, before tax, she paid $25.08. Find the percent tip.
Caroline paid 14% of the cost of the dinner as a tip.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What is percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Extra pay or tip = 25.08 - 22
= $3.08
Now,
Percentage of tip corresponding to the bill amount,
= 3.08 / 22 × 100
= 14%
Thus, Caroline paid 14% of the cost of the dinner as a tip.

Identify the algebraic description that maps a point (3, 7) onto another point (-5, 7).
A) (x,y) → (x-8, y)
B) (x,y) → (x, y - 8)
C) (x, y) → (x, y + 8)
D) (x,y) → (x+8, y)
Answer:
A) (x, y) → (x - 8, y)
Step-by-step explanation:
(3, 7) → (-5, 7)
Without adding or subtracting any values, we can immediately tell that the y-value did not change, but the x-value did. With this, we are left with choices A and D.
A) (x, y) → (x - 8, y)
(3, 7) → (3 - 8, y)
(3, 7) → (-5, 7)
This matches our problem, and therefore, A is the correct answer.
Hope this helps!
Answer:
A) (x, y) → (x-8, y)
Explanation:
Present Point: (3, 7)
Future Point: (-5, 7)
The change be: (x, y)
Solve:
(3, 7) + (x, y) → (-5, 7)
change side
(x, y) → (-5, 7) - (3, 7)
simplify the following
(x, y) → (-8, 0)
Therefore, we identify this using (x - 8, y)
