can someone please tell me how to do 2x=3y and 4x-3y=12 using substitution to solve the system of equations.
Answer:
Step-by-step explanation:
you divide the two to the y, which is x=3/2y
then, you simplify the second equation to y, which is -3y= -4x+12
then, you substitute the x=3/2y into the second equation,
-3y = -6+12
-3y = 6
y = -2
Substitute the y into the first equation, x= 3/2y,
x = -3
Kim drove k miles to see her family. Tran drove 3 times as far as Kim to get to his family's city, plus another 28 miles to get to their house. Which expression represents the number of miles Tran drove?
Answer:
[tex]3k+28[/tex] miles
Step-by-step explanation:
We are given that
Kim drove distance to see her family=k miles
We have to find the expression which represents the number of miles Tran drove.
According to question
3 times of k=3k
Now, adding 28 to 3k
Therefore, the expression is given by
3k+28
Hence, the expression which represents the number of miles Tran drove
[tex]3k+28[/tex] miles

11 - 2x = 45
what are the steps to this
Answer:
x = -17
Step-by-step explanation:
11 - 2x = 45
We first want to subtract 11 from both sides, so that we have the variable and it's factor on its own side. Making the equation:
-2x = 34
Next, we are going to divide each side by the variables' factor, which in this case is -2. However, there is a slightly longer way to do this, but when you're doing it by hand, it is much easier. I will be showing that way below.
So, instead of dividing either side by -2, we are going to divide both sides by 2. Giving us:
-x = 17
This next step is easy peasy. Since the negative is on the variables side and we need the variable to be positive, we just switch the position of the negative to the numerical side. Shown below.
-x = 17
to
x = -17
So, our final answer is x = -17
Hope this helps!
Answer:
Step-by-step explanation:
Solution
11 - 2x = 45
or, 2x=11-45
or, 2x=-34
x=-17

y is such that 4y - 7 ≤ 3y and 3y ≤ 5y + 8.
A. What range of values of y satisfies both inequalities?
B. Hence express 4y - 7 ≤ 3y ≤ 5y + 8 in the form a ≤ y ≤ b, where a and b are both integers.
( I will give brainliest to whoever answers correctly)
Answer:
-4 ≤ y ≤ 7
Step-by-step explanation:
Inequalities
Solve the system of inequalities:
4y - 7 ≤ 3y [1]
3y ≤ 5y + 8 [2]
A.
Subtracting 3y to [1]:
y - 7 ≤ 0
Adding 7:
y ≤ 7
Subtracting 5y to [2]:
-2y ≤ 8
Dividing by -2 (and flipping the sign):
y ≥ -4
The solution of the system is all the values of y greater or equal to -4 and less or equal to 7.
B.
The solution can be expressed as:
-4 ≤ y ≤ 7

Solve for x in simplest form.
2= 1/2 (5x-8)
Answer:
x = [tex]\frac{12}{5}[/tex]
Step-by-step explanation:
Given
2 = [tex]\frac{1}{2}[/tex] (5x - 8) ( multiply both sides by 2 to clear the fraction )
4 = 5x - 8 ( add 8 to both sides )
12 = 5x ( divide both sides by 5 )

Answer:
$36
Step-by-step explanation:
2/3 = $24
divide 24 by 2 to find 1/3
1/3 = $12
3/3 = (12 + 12 + 12 )
3/3 = 36

This is a simple problem.
One circle labeled likes 13 overlaps another circle labeled male 16. The overlap is labeled 6. A 4-column table with 3 rows. The first column has no label with entries female, male, total. The second column is labeled likes with entries a, c, 19. The third column is labeled dislikes with entries 15, 16, e. The fourth column is labeled total with entries b, d, 50.
A group of 50 people were asked their gender and if they liked cats. The data from the survey are shown in the Venn diagram.
Determine the value for each variable in the two-way table.
a =
b =
c =
d =
e =
Please give me the right answer!
Answer:
E = 15 +16 = 31
6 males like cats ( the middle section) so C = 6
d = 6 +16 = 22
a = 19-6 = 13
b = 50-22 = 28
so in order: a = 13, b = 28, c = 6, d = 22, e = 31
Step-by-step explanation:
The required value for each variable in the two-way table is given as, a = 13, b = 28, c = 6, d = 22, and e = 31.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
From the table,
e = 15 + 16 = 31
At the middle of the table, c = 6 {6 males like cats}
d = 6 + 16 = 22
a = 19 - 6 = 13
b = 50 - 22 = 28
Thus, the required value for each variable in the two-way table is given as, a = 13, b = 28, c = 6, d = 22, and e = 31.

What must m∠QPS be for PQRS to be a parallelogram?
Answer:
It’s B
Step-by-step explanation:
For the shape to be a quadrilateral, then the value of ∠QPS must be (b) 59 degrees
For quadrilateral PQRS to be an actual quadrilateral, then:
[tex]\angle RQP = \angle PSR[/tex] --- opposite angles of quadrilateral[tex]\angle QPS + \angle PSR = 180[/tex] --- adjacent angles of quadrilateral[tex]\angle RQP = \angle PSR[/tex] implies that:
[tex]6x + 13 = 7x - 5[/tex]
Collect like terms
[tex]6x - 7x = -13 - 5[/tex]
[tex]-x = -18[/tex]
Multiply both sides by -1
[tex]x = 18[/tex]
[tex]\angle QPS + \angle PSR = 180[/tex] implies that
[tex]\angle QPS + 7x - 5 = 180[/tex]
Substitute 18 for x
[tex]\angle QPS + 7(18) - 5 = 180[/tex]
Collect like terms
[tex]\angle QPS= 180 +5 - 7(18)[/tex]
[tex]\angle QPS= 59[/tex]
Hence, the measure of angle QPS must be (b) 59 degrees

A side of the triangle below has been extended to form an exterior angle of 146°. Find
the value of x.
146°
.
Answer:
The measure of angle x° = 34°.
Step-by-step explanation:
It is given that a
We know that side of the triangle below has been extended to form an exterior angle of 146°.
It is clear that x° and 146° are adjacent angles.It is clear that x° and 146° lie on a straight line.We know that a straight line makes a straight angle of 180°.
Thus,
The sum of x° and 146° must be 180°.
x° + 146° = 180°
subtract 146° from both sides
x° + 146° - 146° = 180° - 146°
x° = 34°
Therefore, the measure of angle x° = 34°.

How many centimeters are there in 2 yards if there are 2.54 centimeters per inch. Show your work and express your answer without rounding.
Answer:
There are 182.88 cm in 2 yards.
Step-by-step explanation:
Given that,
1 inch = 2.54 cm
We need to find how many centimeters are there in 2 yards.
We know that,
1 yard = 36 inch
⇒ 2 yards = (2×36) inches
= 72 inches
It means,
72 inches = (72 × 2.54) cm
= 182.88 cm
Hence, there are 182.88 cm in 2 yards.

Colin buys a car for £45500. It decreases in price 6% per year. How much will it be worth in 3 years?
Answer:
The answer is 33,710 euros.
Step-by-step explanation:
Start by multiplying 45,550 by 6%. This will give 2,730. over the next three years the price decreases, so multiply 2,730 by 3, which is 8,190. Finally, subtract 45,550 by 8,190 to get 33,710.
Isabelle has $5.45 in her purse. If she has five more nickels than dimes, and twice as many quarters than dimes, how many of each type of coin does she have?
Answer:
Nickel = 13
Dimes = 8
Quarters = 16
Step-by-step explanation:
Let N denote Nickel,
Let D denote dime
Let Q denote quarter
Now, from online conversions;
1 nickel = 5 cents
Also, 1 dime = 10 cents
Also, 1 quarter = 25 cents
Isabelle has $5.45 which is also 545 cents.
Thus, we have;
5N + 10D + 25Q = 545 - - - (eq 1)
We are told that;
she has five more nickels than dimes, and twice as many quarters than dimes.
Thus;
N = D + 5
Also, Q = 2D
Plugging them for N and Q in eq 1 givens;
5(D +5) + 10D + 25(2D) = 545
5D + 25 + 10D + 50D = 545
25 + 65D = 545
65D = 545 - 25
65D = 520
D = 520/65
D = 8
Thus; N = D + 5 = 8 + 5 = 13
Q = 2D = 2 × 8 = 16
