First multiply them all by 8
2x - 1 = 7 + 4x
Subtract 2x
-1 = 7 + 2x
Subtract 7
-8 = 2x
Divide by 2
X = -4

The cost of a phone has increased by 10% to £352 work out the original price
lions [1.4K]
The answer is £316.80.

This is because you're working out the original price from a percentage increase.

To do this, you do the original price ÷ (1- percentage increase as a decimal).

So it would be 352 ÷ (1 - 0.10) which is 352 ÷ 0.9.

And that equals to £316.80.

At a local carnival, Mia is shooting at a row of 10 duck targets. Each time she shoots at a duck, the duck she shoots and any du
zubka84 [21]

Using the combination formula, it is found that she can shoot the ducks in 120 ways.

<h3>What is the combination formula?</h3>

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by:

C_{n,x} = \frac{n!}{x!(n-x)!}

In this problem, 3 ducks will be shoot from a set of 10, hence:

C_{10,3} = \frac{10!}{3!(10-3)!} = 120

Thus, she can shoot the ducks in 120 ways.

Rachel mows 5 lawns in 8 hours. At this rate how many lawns can she mow in 40 hour?
posledela

We can think of this as an equality

5 Lawns = 8 Hours

If she needs 40 hours, you can multiply 8 hours by 5 to get 40, but now it's not balanced. So, you need to multiply 5 to the other side too so:

5 x (5) = 8 x (5)

Therefore she mows 25 Lawns in 40 Hours
