what is a linear equation that is perpendicular to y=5
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.

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.

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

Case 1 = 4 blocks case 2 = 9 blocks case 3 =16 blocks. How many blocks are need for the 9th case?
9514 1404 393
Answer:
100
Step-by-step explanation:
4 = 2² . . . case 1
9 = 3² . . . case 2
16 = 4² . . . case 3
The number of blocks is the square of the number 1 greater than the case number. For case 9, the number of blocks is (9+1)² = 10² = 100.
100 blocks are needed for the 9th case.

1/3 divided by what equals 1/12
Answer:
You cannot get a positive answer for this, nor can you divide. You could however divide 1/12 by 1/4 to get 1/3.
Step-by-step explanation
The number whose 1/3 is 1/12 is 4.
What is Division?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
let 1/3 divided by x equals 1/12.
So, 1/3 ÷ x = 1/12
and, 1/3 (1/x) = 1/12
1/x = 3/12
1/x = 1/4
x = 4
So, the required number is 4.
