Answer: 8(2x+7y)

Step-by-step explanation:

Factorisation here, in equation basically means, to put it into brackets.

Step 1 :

First we have to look for if anything is common, and there is! We can do the GCF of both numbers, the answer we will get will be out of the brackets.

GCF of 16 and 56 is 8

Step 2 =

No we do this =

8 x what is 16x? 2x

8 x what is 56y? 7y

so we got this = 8( 2x+7y)

Jonathan measured 2 cups of flour into a bowl on the counter. Than he spilled part of it, now there is 3/8 left. how much did he spill?

Answers

Answer:2 cups was our starting point and we were left with 3/8 cups left after he spilled it, we are looking to find how much he spilled.

We could start by making 2 into a fraction so we could minus 3/8 easily.

2 = 16/8 (Two wholes is 16 eights.)

Now solve like a regular subtraction equation.

16/8 - 3/8 = 13/8

Our answer is 13/8 which simplified as a mixed fraction is 1 5/8

Scott has 25 counters. He gives 10 of the counters to Alex. a) What fraction of the 25 counters does Alex get? Give your answer in its simplest form. b) What fraction of the 25 counters does Scott have now? Give your answer in its simplest form.

Answers

Answer: a) Alex gets 10 counters out of 25, so the fraction of the counters he gets can be expressed as 10/25. To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 5:

10/25 ÷ 5/5 = 2/5

So, Alex gets 2/5 of the 25 counters.

b) After giving 10 counters to Alex, Scott has 25 - 10 = 15 counters left. So, the fraction of the 25 counters that Scott has now can be expressed as 15/25:

15/25 ÷ 5/5 = 3/5

So, Scott now has 3/5 of the 25 counters.

Step-by-step explanation:

Answer:

Step-by-step explanation:

a) The counters that are in Alex= 10

The Fraction of 25 counters is = 10%25

Hence, the fraction of counters does Alex get is 2/5

b) Let the number of counters does Scott have = 25-10 =15

The fraction of 25 counters is = 15%25

Hence, the fraction of counters does Scott get is 3/5

Identify the constant of proportionality.

Answers

Answer: 10

Step-by-step explanation:

The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

So,

Let's take every point of the graph, than apply the equation.

When y is 10:

k = 10/1

When y is 20:

k = 20/2

When y is 30:

k = 30/3

When y is 40:

k = 40/4

When y is 50

k= 50/5

EVERY TIME, the answer is 10, take any point when this line graph is enlarged, the point on the line, are always going to be 10.

When y is (10) , then, x is 1 (as the point is in the x axis = 1

When y is (20), then, x is 2 (as the point is in the x axis = 2
