Which of the following

Answer:

y = 1.6x

Step-by-step explanation:

y is the total amount/pounds of almonds that Lark bought. x is the amount that Tessa bought. 3/5 is the same as 0.6. If we multiplied Tessa's amount by 0.6 it would decrease by 2/5 so we have to add 1 to make it 1.6. To find how much Lark bought multiply 1.6 and Tessa's amount.

Answer:

There were 30 questions on the test so she got 3 questions wrong.

Step-by-step explanation:

Given that:

Correct answers by Emma = 27

Percentage of correct answers = 90%

Let,

x be the total number of questions on test

90% of x = 27

[tex]\frac{90}{100}x=27[/tex]

[tex]0.9x=27[/tex]

Dividing both sides by 0.9

[tex]\frac{0.9x}{0.9}=\frac{27}{0.9}\\x=30[/tex]

There were 30 questions on the test.

Wrong answers = Total questions - Correct answers

Wrong answers = 30-27 = 3

Hence,

There were 30 questions on the test so she got 3 questions wrong.

Answer:

y = (4/25)x

Step-by-step explanation:

We are given;

y = 16/5 and x = 20

Now if y varies directly with x, then we can say;

y = mx

Where m is constant of proportionality

This means that;

16/5 = 20m

Divide both sides by 20 to get;

(16/5) × 1/20 = m

16/100 = m

m = 4/25

Thus,the equation is:

y = (4/25)x

Answer:

Step-by-step explanation

they answer would be a whole number because you are multiplying by one thousand

Using the principle of proportionality, the number of nails that will be produced by 1 machine in 1 hour is [tex] 21 \frac{3}{5} \: thousand [/tex]

Let :

Using Principle of variation :

Using a row from the table :

t = 15 ; n = 81/5

3 = (81/5)k / 15

Cross multiply :

3 × 15 = (81/5)k

45 = (81/5)k

Divide both sides by (81/5) to isolate k

(45 ÷ 81/5) = k

k = (45 × 5/81) = 25/9 = 2.7777

Substituting the value of k into the expression:

[tex] m = \frac{\frac{25}{9}n}{t} [/tex]

We can use the expression to obtain, the value of n ; when m = 1 and t = (1 hour = 60 minutes)

[tex] 1 = \frac{\frac{25}{9}n}{60} [/tex]

[tex] 60 = \frac{{25}{9}}{n}[/tex]

Divide both sides by 25/9 to isolate n

[tex] 60 \times \frac{9}{25} = n [/tex]

[tex] n = \frac{540}{25} = 21 \frac{3}{5} \: thousand \: nails [/tex]

Answer:

7x12x13=1092

Step-by-step explanation:

Answer:

A-1/P=n

Step-by-step explanation:

step 1. look at the parentheses and use inverse operations on both sides

A=P(1+n)

-1       -1

step 2. divide both sides by P

A-1=P(n)

/P    /P

n= A-1/P

The value of n on solving the equation A = P (1 + n) is A / P - 1.

An assertion that two mathematical expressions have equal values is known as an equation. An equation simply states that two things are equal. The equal to sign, or "=," is used to indicate it.

Given:

A = P (1 + n),

Here we can solve the parentheses by using the distributive property as shown below,

A = P × 1 + P × n

A = P + nP

Transform as shown below,

nP = A - P

n = (A - P) / P

n = A / P - 1

Thus, the value of n is A / P - 1.

Answer:

  p = (1, 2)

Step-by-step explanation:

We want ...

  (p -a)/(b -p) = 1/2

  2(p -a) = b -p . . . . . cross multiply

  3p = b +2a . . . .. . . rearrange

  p = (b +2a)/3

  p = ((7, -2) +2(-2, 4))/3 = (7 -4, -2 +8)/3 = (3, 6)/3

  p = (1, 2)

Answer:

The complete table will be:

x        y

1        5

0.8    4

0.4    2

Step-by-step explanation:

Given rule is:

y = 5x

In the given rule, x is multiplied by 5 to get the values of y. The same rule can be manipulated to find the value of x in terms of y.

[tex]\frac{y}{5} = \frac{5x}{5}\\x = \frac{y}{5}[/tex]

Putting y = 5

[tex]x = \frac{y}{5}\\x = \frac{5}{5}\\x = 1[/tex]

Putting y = 4

[tex]x = \frac{y}{5}\\x = \frac{4}{5}\\x = 0.8[/tex]

Putting y = 2

[tex]x = \frac{2}{5}\\x = 0.4[/tex]

Hence,

The complete table will be:

x        y

1        5

0.8    4

0.4    2
