Answer:

a. 2x+3z

b. 7xy

c.   \frac{3ab}{2c}

d. 10z-6q

e. Subtract xy from the sum of p and q.

f.  Divide the sum of 3 and y by 5.

g. Subtract 2c from the square root of b.

h. 3x ... 4x ...

i. 3y ... y+5 ... 5y+5

j. length ... 3 ... breadth ... 8b ... 3b²

Step-by-step explanation:

Sum means addition. 2x + 3z

Product means multiplication. 7y × x = 7xy

Divide 3ab by 2c. 3ab ÷ 2c = \frac{3ab}{2c}

Subtract 6q from 10z.  10z-6q

(p+q)-xy : Subtract xy from the sum of p and q.

(3+y)/5: Divide the sum of 3 and y by 5.

\sqrt{b}- 2c: Subtract 2c from the square root of b.

Let the number of boys be x. Girls are three times more so 3 × x = 3x. The total would be 3x + x = 4x.

Let Nora's age be y. Father is three times more so 3 × y = 3y. Brother is 5 more so would be y+5. The total would be y + 3y + y + 5 = 5y+5

3b is three times more than b, the breadth. Thus, the length is three times more than the breadth since it is 3b. The perimeter would be 3b + b + 3b + b = 8b. The area would be 3b × b = 3b²

Which of the following could be the perimeter of a rectangle with an area of 18 square centimeters?
otez555 [7]

Answer:

The correct answer is c) 18 centimeters

Step-by-step explanation:

Given:

A = 18 cm²

We know that the formula for calculating area of a rectangle is

A = a · b  where a is length and b is width

Possible choices is  6 · 3 and 9 · 2

Formula for calculating perimeter is

P = 2 ( a + b)

P₁ = 2 (6 + 3) = 2 · 9 = 18 cm²

P₂ = 2 (9 + 2) = 2 · 11 = 22 cm²

The obvious choice is P₁ = 18 cm²

God with you!!!

Which relationship has a zero slope? A two column table with five rows. The first column, x, has the entries, negative 3, negati
horsena [70]

Using linear function concepts, we have that the relationship with a slope of 0 is:

A two column table with five rows. The first column, x, has the entries, -3, -1, 1, 3. The second column, y, has the entries, 2, 2, 2, 2.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

A slope of 0 means that the <u>output is constant</u>, hence the relationship with a slope of 0 is:

A two column table with five rows. The first column, x, has the entries, -3, -1, 1, 3. The second column, y, has the entries, 2, 2, 2, 2.

Need the answer asapp with the working out please thanks :)
patriot [66]
Hi,

The two numbers should be 12 and 30. 12=2x2x3 while 30=2x3x5.

Their HCF is 2x3=6 and their LCM is 2x3x2x5. Because of their HFC, we know that they are both multiple of 6. Also, the question says they both are GREATER than 6, so they can’t be 6 but are 6 times “something”. Thanks to the LCM, we know that “something” is equal to 2 for the first number and to 5 for the second one, the numbers hence being 12 and 30.

I hope this helps. If I was not clear enough or if you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.

Jenny bought a 5 notebooks and 2 pencils, and the total was 9 dollars.
weeeeeb [17]
You would solve this with simultaneous equations, so if we write it as:
5n + 2p = 9
3n + 2p = 6
(subtract)
2n = 3
÷ 2
notebooks = 1.5

Now you would substitute it in:
(3 × 1.5) + 2p = 6
4.5 + 2p = 6
- 4.5
2p = 1.5
÷ 2
pens = 0.75

So your final answer is notebooks are $1.50 and pens are $0.75, I hope this helps!
