The answer is 9.73
explanation:
4+5 is 9 so leave that aside for now

since both 2/5 and 2/6 have a different denomination you have to find the common denomination. the common denomination is 30 because it’s the LCM for both 5 and 6.

Since you multiplied the 5 by 6 you now have to multiply your numerator by 6 which will give you 12/30 and do the same with the 2/6 but instead multiply it by 5 which is 10/30 and then add them together 22/30 after you can simplify them to 11/15 by dividing the numeration and denominator by 2

After that you can convert the fraction into a decimal which would be 0.7333 but since you can round it off and make a shorter answer you have 0.73

Lastly,Don’t forget to add your 9 that we had in the begging which is not 9.73 :)

Which of the algebraic expressions are not linear expressions? Select all that apply. a. 3x - 2 b. -9y c. -7x^2^ + 4x d. -1/2x^2

Sedaia [141]

Answer:

c, d and e

Step-by-step explanation:

A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.

Option a: $3x - 2$

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b: $-9y$

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c: $-7x^2 + 4x$

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d: $-\frac{1}{2} x^2$

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e: $8xy$

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

Hence, c, d and e are NOT algebraic expressions.

Which line is perpendicular to the line whose equation is 5y + 6 = -3x?

Lynna [10]

Answer: B

Step by Step

5y + 6 = -3X

5y = -3X - 6

Y = -3/5X -6/5

Perpedicular is the flip of your slope so -3/5 becomes 5/3X

A chemical company makes two brands of antifreeze. The first brand is 55 % pure antifreeze, and the second brand is 80 % pure an

Likurg_2 [28]

We have 55% and 80% antifreeze. We need 90 gallons of 75%.

F - 55% and E - 80%

A) F + E = 90

B) .55 F + .80 E = 67.50 (which is .75 * 90) Multiplying A) by -.55

A) -.55 F -.55 E = -49.50 (which is -.55 * 90) then adding A) & B)

.25 E = 18

E = 72 gallons of 80% and

F = 18 gallons of 55%

********* DOUBLE CHECK ******************

72 * .80 = 57.60 and 18 * .55 = 9.90

57.60 + 9.90 = 67.50 gallons of antifreeze and we have 90 total gallons

(67.50 / 90) * 100 = 75% correct!
