$2.13
$4

After solving the given expression, the value obtained from it in form of simplest fraction is equal to 5.1/8.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

As per the given data in the question,

a = 7/8

b = -7/16

c = 0.8 and

d = 1/4

And the equation is a+b+cd

7/8 + (-7/16) + (0.8)(1/4)

7/16 + 0.2

= 10.2/16

In simplest form, it is written as 5.1/8.

Answer:

y = 12

x = 4.4

Step-by-step explanation:

Scale factor is calculated by comparing the opposing side lengths and writing them as a fraction:

8/20 = 2/5 is the scale factor now to find the value of x and y we can use this scale

y/30 = 2/5 cross multiply expressions

5y = 60 divide both sides by 5

y = 12

same goes for x:

x/11 = 2/5 cross multiply

5x = 22 divide both sides by 5

x = 4.4

Answer:

Step-by-step explanation:

21 roses are white so that is 70%

so that would be 70/100 and can reduce to 7/10

and the percent of red would be 3/10

so we can do 21 divided by 7 which equals 3

then we can do 3 x 3 because 3/10 which equals 9

then you do 21 + 9= 30

so the answer is 30.

Amy didn't include the negative sign for the 20, so she got an imaginary number.

Richard made it imaginary when he didn't need to. (there isn't a negative sign underneath the radical).

If 1 match releases 1100 joules of heat energy and we know that 1 joule = 0.239 calories. This means that 1 match releases 1100 * 0.239 calories

1 match releases 262.9 calories.

Again, if 1 match produces 262.9 calories, then

1 match = 262.9 calories

x match = 2100 calories

if we cross multiply, we have

1 match * 2100 calories = x match * 262.9 calories

x match = 2100/262.9

x match = 7.987 matches

Therefore, approximately 8 matches are needed

Answer/Step-by-step explanation:

Combine multiplied terms into a single fraction

2.7z+1.2z−6.5=0.7

2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7

Combine multiplied terms into a single fraction

2 7 / 1 0 + 1 . 2 − 6 . 5 = 0 . 7

2 7 /1 0 + 6 5 − 6 . 5= 0 . 7

Find common denominator

2 7 /1 0 + 6 5 − 6 . 5= 0 . 7

[tex]\frac{27z}{10} +\frac{2.6z}{10} +\frac{10(-6.5)}{10} =0.7[/tex]

Combine fractions with common denominator

[tex]\frac{27z+2*6z+10(-6.5)}{10} =0.7[/tex]

Multiply the numbers

[tex]\frac{27z+12z-65}{10} =0.7[/tex]

Combine like terms

[tex]\frac{39z-65}{10} =0.7[/tex]

Multiply all terms by the same value to eliminate fraction denominators

[tex]10*\frac{39z-65}{10} =10*0.7[/tex]

Cancel multiplied terms that are in the denominator

39z-65=10*0.7

Multiply the numbers

39z-65=7

Add 65 to both sides of the equation

39z-65+65=7+65

Simplify

39z=72

Divide both sides of the equation by the same term

[tex]\frac{39z}{39} =\frac{72}{39}[/tex]
