Step-by-step explanation:

She need to buy 10 oranges of $6.40.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit.

We are given that grocery store sells a bag of 7 oranges for $4.48. If Khloe spent $6.40 on oranges, then

We have to do as $4.48 divide by 7

4.48 / 7 =  $0.46

Therefore, Each orange costs $0.64

For 10 oranges;

$0.46 x 10 = $6.40

Answer:

the value of x is 17 cm

Step-by-step explanation:

The computation of x is shown below:

Here we applied the pythagoreans theorem

x^2 = a^2 + b^2

x^2 = 15^2 + 8^2

X^2 = 225 + 64

x^2 = 289

x = sqrt(289)

= 17

Hence, the value of x is 17 cm

Answer:

6/10

Step-by-step explanation:

Answer:

3/5 = 0.6 = 6/10 = 9/15 = 12/20 = 18/30 = 21/35 = ...

Step-by-step explanation:

Multiply the numerator and denominator by the same number:

3/5 = 6/10 = 9/15 = 12/20 = 18/30 = 21/35 = ...

Also, you can divide 3 by 5 to get 0.6

Answer:

81

Step-by-step explanation:

Set up a proportion to find how many total students there are [notice how females are on top and totals are on the bottom of the ratios]

[tex]\frac{4}{9}[/tex] = [tex]\frac{396}{x}[/tex] so cross multiply 4x = 396(9) so x = 891, if there are a total of 891 students and you need 1 teacher per 11 students then take 891/11 so you need 81 teachers.

You could set up another proportion 1/11 = x/891

If there are 396 female students, there are 81 teachers.

Suppose the  real measurements were "a" and "b"

Then their ratio will be formed as

[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]

where  is a common factor (not 1)

This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.

Thus, a = px, b = qx

First, Set up a proportion to find how many total students there are

[notice how females are on top and totals are on the bottom of the ratios]

So, 4/9 = 396 / x

then, cross multiply

4x = 396(9)

so x = 891,

if there are a total of 891 students and we need 1 teacher per 11 students then take 891/11.

Thus, you need 81 teachers.

Also, we could set up another proportion 1/11 = x/891

Hence,  If there are 396 female students, there are 81 teachers.

Answer:

-$360.00 change

Step-by-step explanation:

Now there is either some information missing, like her starting total in the bank; or they want you to explain the net change.  But the way the question is worded it is stating she is paying $30 over 12 months.  This means she has paid $360.00 in that 12 months aka 1 year.  Her bank account should have had a balance.  So you could technically say B for balance.  B-30*12.  To get your answer.  Although there are many ways to write an equation expression of this question.  If you know the starting balance then it's better.  But you could assume her starting balance was $0.  Which would be 0-30M*12 where M could represent monthly.  And the same answer would occur of 360.  Is there more information?

30*12= X (x equals the total paid)

X-30*12 (if x is her balance before paying any money)

Answer:

26

Step-by-step explanation:

m + 5q | Given

1 + 5(5) | Substitute the values

1 + 25 | Distribute (5(5) is the same as writing 5 × 5

26

The solution of m + 5q is 26, where m = 1, and q = 5.

Expressions is the defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

For example 4/2 = 2

Given expression as :

⇒ m + 5q

where m = 1, and q = 5

Substitute the values of m = 1, and q = 5 in the expression and apply the arithmetic operations

⇒ 1 + 5(5)

⇒ 1 + 25

⇒ 26

Hence, the solution of m + 5q is 26, where m = 1, and q = 5.

Answer:

-2

Step-by-step explanation:

(x + 2) ÷ 2 + (x + 4) ÷ 4 = 4

lcm is 6

(x + 2) ÷ 2 × 6 + (x + 4) ÷ 3 × 6 = 4

(x + 2) × 3 + ( x + 4) × 2 = 4

3x + 6 + 2x + 8 = 4

correct like terms

3x + 2x + 6 + 8 = 4

5x + 14 = 4

5x + 14 - 14 = 4 - 14

5x = - 10

5x ÷ 5 = -10 ÷ 5

x = -2
