Solve the equation. Then check your solution. – two-fifths + a = One-fifth a. Three-fifths c. StartFraction 3 Over 10 EndFractio

VLD [36.1K]

Answer:

a = Negative one-fifth

Step-by-step explanation:

The given equation is :

$\dfrac{2}{5}+a=\dfrac{1}{5}$

We need to find the value of a.

Subtract 2/5 from both sides.

$\dfrac{2}{5}+a-\dfrac{2}{5}=\dfrac{1}{5}-\dfrac{2}{5}\\\\a=\frac{1}{5}-\frac{2}{5}\\\\a=\dfrac{-1}{5}$

So, the correct answer is Negative one-fifth. Hence, the correct option is (b).

Question 7 of 10

Ganezh [65]

Answer:

Option B

Step-by-step explanation:

Given Equation :

$\qquad \sf \dashrightarrow \: 3(4x+3) = 2x - 5(3 - x) + 2$

Using distribute property:

$\qquad \sf \dashrightarrow \: 12x + 9 = 2x - 15 + 5x + 2$

Adding the like terms we get :

$\qquad \sf \dashrightarrow \: 12x + 9 = 2x + 5x - 15 + 2$

$\qquad \sf \dashrightarrow \: 12x + 9 = 7x - 13$

Transposing the variables on the right side and constant terms on the left side :

$\qquad \sf \dashrightarrow \: 12x - 7x = - 13 - 9$

$\qquad \sf \dashrightarrow \: 5x = - 22$

Dividing both sides by 5 :

$\qquad \sf \dashrightarrow \: \dfrac{5x}{5} = \dfrac{ - 22}{5}$

$\qquad \bf \dashrightarrow \: x = \dfrac{ - 22}{5}$

Factor -75c^2-45c+12

Answer: −3(5c+4)(5c−1)

Step-by-step explanation:

1. Find the Greatest Common Factor (GCF).

GCF=3

2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

3(75c^2/3+45c/3−12/3)

3. Simplify each term in parentheses.

−3(25c^2+15c−4)

4. Split the second term in 25c2+15c−4 into two terms.

−3(25c^2+20c−5c−4)

5. Factor out common terms in the first two terms, then in the last two terms.

−3(5c(5c+4)−(5c+4))

6. Factor out the common term 5c+4

−3(5c+4)(5c−1)
