Answer:

u = 4/5

Step-by-step explanation:

Expand

2u - 2 - 6 = 20u - 20 - 3u

Rearrange with like terms on either side

12 = 15u

u = 4/5

Answer:

u=4/5

Step-by-step explanation:

First, parentheses/multiply on both sides.

2u-2-6=20u-20-3u <--- two negatives make a positive

Next, add/subtract like terms.

2u-8=17u-20

Then, add 8 to both sides.

2u=17u-12

Finally, get "u" by itself. Subtract "17u" to both sides and then divide "-15" to both sides

-15u=-12

u=4/5

Some campaigners want a maximum wage. This would be in a ratio of 10:1 with the minimum wage. If the minimum wage is £8.72 an ho
Nady [450]

Answer:

The value of the maximum wage is £87.2

Step-by-step explanation:

Here, we want to get the maximum wage given the ratio it has with the minimum wage

To get the value of the maximum wage, we proceed to multiply the value of the minimum wage by 10

Mathematically, that would be;

8.72 * 10 = £87.2

The quadrilaterals ABCD and JKLM are similar. find the length x of MJ
Rina8888 [55]

Answer:

x = 5.6

Step-by-step explanation:

So, lets first go over something:

What does it mean for two shapes to be similar?

It means that all their angles are the same, but their side lengths are different, or in other words, one triangle has a different ratio of side lengths to the other.

So how can we find this ratio difference?

We can take the lengths of the same sime on the two different traingles.

You could go with 4 : 3.2 or 2 : 1.6

When you simplfy this, you get 1 : 0.8

We can then find the value of x by multiplying the two ratios by 7, which is the side length of the similar triangle's unknown side:

7 : 5.6

This means that x = 5.6

Hope this makes sense!
