Answer:
x = -3/2, 1/2
Step-by-step explanation:
(2x + 3)(2x - 1) = 0
2x + 3 = 0, 2x = -3, x = -3/2
2x - 1 = 0, 2x = 1, x = 1/2
Answer:
2x + 5y = 36 in standard form
Step-by-step explanation:
m =
y - = m( x - )
~~~~~
(3, 6)
(8, 4)
m =
y - 6 = ( x - 3 )
y = x + in slope-intercept form
2x + 5y = 36 in standard form

Answer: 8/10
Step-by-step explanation: Using the place value chart, we can see that 0.8 means eight-tenths which can be written as the fraction 8/10. Since 8/10 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 8 and 10 which is 2 to get 4/5.
Therefore, 0.8 can be written as the fraction 8/10.
The decimal number 0.8 in the simplest fraction form will be 4/5.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of a numerator and a denominator.
The decimal number is given below:
⇒ 0.8
Multiply and divide the expression by 10. Then we have
⇒ 0.8 x 10 / 10
⇒ 8 / 10
⇒ 4 / 5

b. The equation 2/3(x + 400 + 350) = x can be used to model the situation.
c. Leena consumed 500 calories at dinner.
d. The equation 2/3(x) = x(400 + 300) can be used to model the situation.
e. Leena consumed 1,000 calories at dinner.
f. The equation 2/3x(400 + 300) = x can be used to model the situation.
Only Option 'A' and 'B' are correct.
a) Leena consumed 1,500 calories at dinner.
b) The equation 2/3(x + 400 + 350) = x can be used to model the situation.
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Since, we have given that
Number of calories she consumed at breakfast = 400
Number of calories she consumed at lunch = 350
Now, Let number of calories she consumed at dinner be x
According to question,
She consumes 2/3 of her daily calories at dinner,
So, it becomes,
1/3 x total = 400 + 350
total = 2250
so, Number of calories she consumed at dinner is given by
2/3 of total = x
2/3 x 2250 = x
x = 1500
And by option 'B' we get,
2/3 (x + 400 + 350) = x
2 (x + 750) = 3x
2x + 1500 = 3x
x = 1500
So, only Option 'A' and 'B' are correct.
