Answer:[tex]-\frac{3}{8} x +7y=-1[/tex]
Step-by-step explanation:
Standard form is ax+by=c, where a,b,c are coefficients.
We are given [tex]7y=\frac{3}{8} x-1[/tex]. All we have to do is move some terms around so that the X is on the left side.
[tex]7y=\frac{3}{8} x-1[/tex] [subtract both sides by 3/8x]
[tex]-\frac{3}{8} x +7y=-1[/tex]
This gives out final answer of [tex]-\frac{3}{8} x +7y=-1[/tex].

with the ground. What’s the horizontal distance between the base of the ladder and the wall? Round your answer to the nearest tenth of a foot if necessary.
A right triangle is created by the wall and the ladder's base. 9.3 feet are horizontally between the wall and the ladder's base.
What are right triangles?A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or formerly rectangle triangle, is a triangle with one right angle, or two perpendicular sides.
The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
So, the parameters listed are:
69-degree angle.
Ladder length (l) equals 26 feet.
The following cosine ratio is used to compute the horizontal distance (h).
cos(θ) = h/l
Replace known values:
cos(69) = h/26
Make the topic "h":
h = 26 * cos(69)
Consider the product:
h = 9.3
Therefore, a right triangle is created by the wall and the ladder's base. 9.3 feet are horizontally between the wall and the ladder's base.

Ben and tom each take driving test. The probability that ben and tom will pass is 0. 87 and 0. 7 respectively
The probability that ben and tom will pass is 0. 87 and 0. 7 respectively will be 0.38
The answers to the questions are as follows:
Please refer to the attached file for point a.
Since both of them pass their driving tests at the same time, we double the odds of each one passing, which results in a probability of "56%".
Tom passes but Ben fails, or Tom passes but Ben succeeds. Therefore, the likelihood and the response is "38%."
(a)The tree diagram is attached.
P(Ben Fails)=1-0.8=0.2
P(Tom Fails)=1-0.7=0.3
(b)Probability that both will pass their driving test.
P(both will pass)=0.8 X 0.7 =0.56
(c)Probability that only one of them will pass their driving test.
P(Tom Bass, Ben Fails OR Ben Pass, Tom Fails)
=(0.7 X 0.2)+(0.8 X 0.3)

The total number of $12 tickets are 120 while the $15 tickets are 180.
What is algebraic expression?In addition to using operational signs, algebraic expressions also include numbers and variables. Examples include multiplication, multiplication with the natural exponent, division, and addition, subtraction, and exponentiation. The term "fractional expression" refers to division in an algebraic expression with variables.
The term "rational numbers" refers to numbers that can be expressed as fractions. Integers, repeating decimals, and terminating decimals are a few examples.
Given that x stands for $12 tickets and y stands for $15 given as the equation
12x + 15y = 4140
x + y = 300
y = 300 - x
Substitute the value of y in the first equation
12x + 15(300 - x) = 4140
12 x + 4500 - 15x = 4140
12x - 15x = 4140 - 4500
-3x = −360
x = 360/3
x = 120
y = 300 - (120)
y = 180
Thus, The total number of $12 tickets are 120 while the $15 tickets are 180.

Explain how your equation determines a linear measurement when the original equation determined a cubic measurement
The volume of a cone is V = πr²h/3
The equation rewritten to solve for the height is V = πr²h/3
How to determine the equationIt is important to note that the formula for volume of a cone is expressed as;
V = πr²h/3
The parameters are;
V is the volume of the coneπ takes the constant value, 22/7 or 3. 142h is the height of the coneSince the ice cream fits inside the cone and the height still holds the ice cream, let's make the height subject of formula.
Let's take the following steps;
V = πr²h/3
cross multiply the equation, we get;
V × 3 = πr²h × 1
Multiply the values
3V = πr²h
To make the variable 'h' stand alone, let's divide both sides of the equation by its coefficient
3V/πr² = πr²h/πr²

A toy store had 4 boxes that weighed a total of 34 kilograms. If each box had the
same amount of weight, how much did each box weigh? Between what two whole
numbers does your answer lie?
The weight lies between the whole numbers 8 and 9.
The length, breadth, and height of a package are multiplied using the longest point on each side to determine the dimensional (DIM) weight.
If each of the 4 boxes has the same weight, the weight of each box can be found by dividing the total weight by the number of boxes. Given that the total weight is 34 kilograms, the weight of each box is:
w = 34 kg / 4 boxes = 8.5 kg
So, each box weighs 8.5 kilograms. The weight lies between the whole numbers 8 and 9.

What are linear inequalities?
Inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths. In this case, the equal sign “=” in the expression is replaced by any of the inequality symbols such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤) or not equal to symbol (≠). The different types of inequalities in Maths are polynomial inequality, rational inequality, absolute value inequality.
The symbols ‘<‘ and ‘>’ express the strict inequalities and the symbols ‘≤’ and ‘≥’ denote slack inequalities. A linear inequality seems exactly like a linear equation but there is a change in the symbol that relates two expressions.

If in the first week of July, a record 1,120 people went to the local swimming pool. the percent decrease in the number of people who went to the pool over these four weeks is 10%.
How to find the percentage decrease?First week:
Number of people went to the local swimming pool =1120

Please answer!!! The inspector at a bottling plant checks 25 bottles. Two bottles do not pass inspection. All the bottles hold the same number of milliliters of sports drink
The equivalent expression for the amount of sports drinks that pass inspection is 23x milliliters.
The inspector at a bottling plant checks 25 bottles, and two bottles do not pass inspection.
To find the amount of sports drinks in milliliters that pass inspection, we can subtract the amount in the two bottles that do not pass inspection from the total amount in all 25 bottles.
Let x be the amount of sports drinks in milliliters in each bottle.
The expression for the milliliters of sports drink that pass inspection is = 25x - 2x
Now, simplifying the expression, we get,
25x - 2x = (25-2)x = 23x

The vertices of YEAR are Y(1,-4) E(3,0), A (-1,2) and R( -3,-2) . prove that YEAR is a Square
To prove that YEAR is a square, we need to show that all four sides have the same length and all four angles are right angles (90 degrees).
Side Lengths: To find the lengths of the sides, we can use the distance formula:
d = √((x2 - x1)² + (y2 - y1)²)
For example, to find the length of the side that connects Y and E, we can use the following calculation:
d = √((3 - 1)² + (0 - (-4))²) = √((2)² + (4)²) = √(4 + 16) = √20
We can use the same formula to calculate the lengths of the other sides. By doing so, we will find that the length of all four sides are the same, which is √20. This means that all four sides of YEAR are congruent, and therefore it is a square.
