Solve for x: 4(x+5)=3(x-2)-2(x+2)
Zina [86]

Answer:

x = -10

Step-by-step explanation:

Solve the equation by simplifying according to PEMDAS. Then use inverse operations to solve.

4(x+5) = 3(x-2) -2(x+2)

4x + 20 = 3x - 6 - 2x - 4

4x + 20 = x - 10

3x = -30

x = -10

15/20 times 1/4 thank me if u like brainly
MaRussiya [10]

Answer: 3/16

Step-by-step explanation: To multiply fractions, first multiply across the numerators and then multiply across the denominators.

\frac{15}{20} × \frac{1}{4} = ?

15 × 1 = 15

20 × 4 = 80

\frac{15}{20} can be reduced by dividing both the numerator and denominator by the Greatest Common Factor which is 5.

15 ÷ 5 = 3

80 ÷ 5 = 16

Therefore, \frac{15}{20} × \frac{1}{4} = \frac{3}{16}
