$3d-2d=-17-8$ | Like terms on each side

$d=-25$ | simplify

It's important do do the same thing to both sides so the equation will stay equal
exg
3=3
multipy 4
12=12
still true

so 3d+8=2d-17
2d means 2 times d or d+d

so
3d+8=2d-17
subtract 2d from both sides
3d-2d+8=2d-2d-17
d+8=-17
subtract 8 from both sies
d=-25

d=-25

Whats 9 divide by 6.5

dezoksy [38]

It's an irrational number which means the number never ends and has no pattern in its decimal. So you would round it:
9/6.5= 1.384615384615385
but the answer would be 1.384

In a sale there is 25%off on all prices an TV costs £90 in the sale. How much was it before the sale?

Elina [12.6K]

To work out how much something was before the discount, you have to divide the price (which is £90) by 75 (as this is the percentage that you paid). It's gives you £1.20. Therefore, 1% is £1.20. To find the original cost, which is 100%, you have to multiply it by 100. Multiplying £1.20 by 100 gives you £120. Therefore, the cost of the TV before the 25% reeducation was £120. Hope this helps :)

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 3 inches. The height of the cone is 18 inc

Bond [772]

The relationship is that two times the volume of cylinder is volume of cone

Solution:

Given that, cylinder and a cone have the same diameter: 8 inches

Diameter = 8 inches

Radius is diameter divided by 2

$radius = \frac{diameter}{2}\\\\radius = \frac{8}{2} = 4$
