how to write an equation
Answer:
Step-by-step explanation:
An equation is like a sentence, just using a different language. Mathematical equations are telling you to do something, giving you information on how to respond, or come up with an answer. It's up to you to learn this language. However, once you know it, you can write in this language! You, too, can write algebraic equations.
Parts of a Mathematical Equation
A mathematical equation, also known as a statement, shows that two separate expressions are equal. The two expressions are usually connected by the "equal-to" (=) sign. You can find the expressions in a mathematical statement by looking at the left-hand side and the right-hand side of the equation, using the = sign as the point of reference.
Example: 2x + 3 = 11
It can be helpful to view equations as a scale in which weights are used to keep it balanced. The scale is balanced when what is placed on the right-hand side is equal in weight to what is on the left-hand side. Solving an equation can also be thought of in terms of adding weight to the left or right-hand side of the scale to balance it out.
Finding the solution to the equation involves manipulating the weights. Whatever is done on the right-hand side of the scale must also be done on the left-hand side to keep the scale balanced.
Your tools for this happen to be, most commonly, addition, subtraction, multiplication, or division.
Answer:
An equation uses symbols and numbers there are SO many equations you could make for example an easy one 6 x 5 = 30 there are two numbers you multiply to get a product. Whenever you write an equation you always put an equal sign which is this: = . This shows what you get from the equation. There are main parts the =, +, -, x, ÷ . All represent what you do to the two numbers you put on both sides of it.

System of inequalities
ASAP I ONLY HAVE 15 MINS WILLING TO GIVE 20 POINTS
Answer:
y > x - 4
x > 3
Step-by-step explanation:
The system of inequalities need to represent the overlapped, black area, so you need to write an inequality for each of the two lines shown.
To find out whether you should be using a >, <, ≤, or ≥, identify on the graph first:
The vertical line is shaded to the right of the line. The line is also dashed, so it should be a >.
The sloped line is shaded above the line. The line is also dashed, so it should be a >.
Then, find the slopes of the lines.
Refer to the sloped line as Line 1 and the vertical line as Line 2.
The slope of Line 1 is 1. It's y-intercept (where the line crosses the y-axis) is -4.
So: y = x - 4
Replace the = with >.
y > x - 4
Line 2 is unidentified, so you can see that it's x = 3. Replace the = with >.
x > 3
You can always check by plugging in a point from the overlapped area, like (4, 1).
(4, 1)
y > x - 4
1 > 4 - 4
1 > 0
x > 3
4 > 3
These statements are true.
seven more than twice a number is greater than negative fifteen
Answer: 2n > -15
Step-by-step explanation:
We can use the variable n to show the unknown number.
It says that there is twice a number, meaning two of an unknown number. We can show it by using the term 2n.
It also states that 2n is greater than -15. Because of that, we can use the equation 2n > -15, to show that 2n is greater than -15.
(Quick note: The variable n just represents the unknown number, you can subsitutue any variable into its place.)
The Inequality that shows seven more than twice a number is greater than negative fifteen is; 2n > -15
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
We can consider the variable n to show the unknown number.
That says, there is twice a number, meaning two of an unknown number. We can show it by using the term "2n".
It states that seven more than twice a number is greater than negative fifteen
MEans 2n is greater than -15.
we can use the equation 2n > -15, to show that 2n is greater than -15.

solve for x
2x+9≤27
(10 points worth)
Answer:
x = 9
Step-by-step explanation:
First, subtract 9 from both sides, and you are left with 2x < 18. Then, divide 18 by 2 to get 9. I hope this helps :)
The value of x is 9.
To find x
2x+9≤27Subtract 9 from both sides we get,
2x ≤18
Divide 2 from both sides,
x≤9.
Hence, the value of x is 9.

Answer:
y = 6x
Step-by-step explanation:
You can easily find the slope by using slope formula:
(y2-y1) / (x2-x1) (the numbers are subscript)
E.g: (24-12) / (4-2) = 12/2 = 6
m(slope) = 6

Answer:
FE = 11.08, DF = 14.18Step-by-step explanation:
Use trigonometric ratios:
sin = opposite / hypotenusecos = adjacent / hypotenuseApply to the given triangle
Side FE
FE / DE = sin 38° (or cos 52°, the value is same)FE / 18 = sin 38°FE = 18 sin 38°FE = 11.08Side DE

Mrs. Doshi is sewing decorative banners. Each banner uses yards of fabric. Mrs. Doshi has 2yards of fabric. How many banners can she make?
А.
7 banners
B. O None of these
C
6 banners
DO 2 banners
E. O 3 banners
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but let's reframe it and try to solve it.
Let's assume that each banner uses 1/3 yards of fabric and that Mrs. Doshi has 2yards of fabric. To get the number of banners that she can make, we would have to divide the amount if yards that Mrs Doshi has by the amount of yards of fabric that each banner will use. In this case, this will be:
= 2 ÷ 1/3
= 2 × 3
= 6 yards
