What is the solution to -1/4(4/9-3x)-2/9=7/9

liq [111]

Answer:

40/27

Step-by-step explanation:

-1/4(4/9-3x)-2/9=7/9

-1/9+3/4x=7/9+2/9

3/4x=9/9-(-1/9)

3/4x=9/9+1/9

3/4x=10/9

x=(10/9)/(3/4)

x=(10/9)(4/3)

x=40/27

Alvin and Simon shared £540 in the ratio 4:5. Alvin gave half of his share to Theo. Simon gave a tenth of his share to Theo. Wha

Liono4ka [1.6K]

Answer:

$\frac{5}{18}$

Step-by-step explanation:

sum the parts of the ratio, 4 + 5 = 9 parts

Divide the amount by 9 to find the value of one part of the ratio

£540 ÷ 9 = £60 ← value of 1 part of the ratio , thus

4 parts = 4 × £60 = £240 ← Alvin's share

5 parts = 5 × £60 = £300 ← Simon's share

$\frac{1}{2}$ × £240 = £120

$\frac{1}{10}$ × £300 = £30

Theo receives £120 + £30 = £150 , which as a fraction is

$\frac{150}{540}$ ( divide numerator/ denominator by 30 )

= $\frac{5}{18}$ ← in simplest form

3π/4 angle is in the second quadrant, so cos (3π/4) is going to be negative.

Reference angle of 3π/4 is (π - 3π/4) = π/4

cos(π/4) = √2/2

cos (3π/4) = - √2/2

Answer is C.
