I don't know what type of answer you are looking for. But, if you want to find out what X is  than I can give you that.
 Fist combine like terms on the right it will be 3x-5 = 2.5x, than subtract 3x from both side making it -5 = -.5x. Than dived both side by -.5. to get -5/-.5 to get 10.    x = 10

Answer:

£2.85

Step-by-step explanation:

Lucy paid this amount she used six coin remember you have to calculate them to get the 85 and u can't use £1

50+20+10+5=85(£2.85)

50+10+10+10+5=85(£2.85)

20+20+20+10+10+5=(£2.85)

Find the value of x. Round the answer to the nearest tenth, if needed.
zepelin [54]

Answer:

D

Step-by-step explanation:

The diagram is composed of one large right triangle and inside it it's divided into 2 small right triangles. Since these triangles all have the same shape but not the same size, they are similar triangles. Using similar triangles, create a proportion of side lengths. A proportion is an equation with equal ratios from the large triangle to a small. Notice the large triangle has a hypotenuse of 6+7 = 13 and a leg of x. The small triangle has a hypotenuse of x and a leg of 7.

\frac{hypotenuse}{leg}=\frac{hypotenuse}{leg}

\frac{13}{x}=\frac{x}{7}

To solve for x, cross multiply the numerator with the denominator.

x*x = 13*7\\x^2 = 91\\x=\sqrt{91} \\x=9.5

nikdorinn [45]

Answer:

2x² + 3x + 4

Step-by-step explanation:

Using synthetic division to divide by x - 1

  1 |   2   1   1   - 4

        ↓   2  3    4

     ---------------------

         2  3   4   0 ← remainder = 0
