You just have to find what number times 9 equals your original equation so 9 and -2 are -18 and 9 and 3 are 27 so your distributed equation would be:

9(-2x+3)

Answer:

∠x = 72°

Step-by-step explanation:

since two sides are equal, their opposite angles are equal.

Then the upper angle is also equal to 54°.

All triangle angles add up to 180°.

∠x = 180 - 54 - 54 = 72°

lemon squash 2 parts concentrate to 5 parts of water. if you put 90ml of concentrate in a glass, how much water should be added?

snow_lady [41]

It is given in the question that in the lemon squash 2 parts concentrate is added to 5 parts of water. Thus it makes the concentrate to water ratio as 2:5 or $\frac{2}{5}$ . Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:

$\frac{2}{5}=\frac{90}{x}$

Where x is the amount of water to be added, in ml (milliliters).

Cross multiplication of the above equation will give us:

$2x=90\times 5=450$

Dividing both sides by 2 we will get:

$x=\frac{450}{2}=225$

Thus, if we put 90ml of concentrate in a glass, the water that should be added must be 225 ml.

Pls i need help with this question

otez555 [7]

There would be 6 waters and 5 snack mixes. Each water is 1.25, so 1.25x6 would be 7.50. And each snack is 2.50, so 2.50x5 would be 12.50. Adding those two or es together would be exactly $20 and adding all the items is 11. Hope this helps:)
