Vikki [24]

Answer:

200g of sugar, 600g of flour, 400g of butter

Step-by-step explanation:

50g sugar = 15 biscuits

3 x 50g = flour --) 150g = flour

2 x 50g = butter --) 100g = butter

60/15 = 4; 4 times as much

4 x 50g = 200g of sugar

4 x 150g = 600g of flour

4 x 100g = 400g of butter

Kevin bought a membership to a golf club. He pays $250 per month and $18 every time he plays a round of golf. Write an equation
Arturiano [62]
Hi there!

Let's solve this problem step by step!

The cost of 1 round of golf is $18
and therefore the total cost for all of the tickets is $18 × 
the amount of golf plays, mathematically $18 × g, hence 18g

The membership cost of 1 month is $250
and therefore the total cost for all of the tickets is $250 × 
the amount of months, mathematically $250 × m, hence 250m.

Now we can set up the equation. The only thing we need to do is adding up the individual functions.

Answer:
C = 250m + 18g

What is the answer to 8x-2=-9+7x
Alika [10]

Well I don't know !
Let's get together and figure it out.  Are you with me ?

                 You said that             8x - 2 = -9 + 7x

Add  2  to each side:                  8x      = -7 + 7x

Subtract  7x  from each side:     x        = -7

Now that wasn't so bad, was it ?
