All you have to do is set up 2 proportions, where one paint you know and the other you do not know and make it equal to the ratio as 2 blue : 5 yellow

For example: 1 blue/x yellow = 2 blue/5 yellow, and then cross multiply and solve for x.

Do this for all unknowns, blue and yellow paint making it equal to the ratio and solve for the unknown.

16. Mum went shopping at the vegetable stand.
kondaur [170]

Good evening

Answer:

<em>a) the cost of one apple is €</em><em>0.9</em>

<em>b) the cost of one pineapple is €</em><em>5.4</em>

<em>c) the cost of two pineapples and six apples is €</em><em>16.2</em>

Step-by-step explanation:

Consider P the price of a pineapple

               A the price of an apple

A pineapple costs six times as much as an apple means P = 6A

Mum paid €7.20 for one pineapple and two apples means P + 2A = 7.20

then

6A + 2A = 7.20

then

8A = 7.20

then

A = €0.9  

Since P = 6A then P = 6×(0.9) = €5.4

the cost of two pineapples and six apples

= 2P + 6A

= 2P + P

= 3P

= 3×(5.4)

= €16.2

What value of x will make the given triangles congruent?
Molodets [167]
Because you're trying to make them congruent, equal the two expressions to each other. 

So, for #10 you would equal them so it would look like this. 
2x+2=5x-19

Then you would just go ahead and simplify

2x+2=5x-19
-2x     -2x
---------------
2= 3x -19
+19    +19
---------------
21=3x
---  ----
3     3

x=7

This means that x should be 7. You can check this just by plugging it in

2x+2
2(7)+2 = 16

5x-19
5(7)-19= 16

Same with #11.

x+8=3x-14
-x     -x
--------------
8=2x-14
+14   +14
--------------
22=2x
---  ----
2     2

x=11

Check. 

x+8
11+8= 19

3x-14
3(11) - 14 = 19
