A 150​-gram bag of berries is a mixture of raspberries and blueberries. If ​80% of the bag is​ raspberries, how many grams of blueberries are in a​ bag?

30g

Step-by-step explanation:

Since the bag is a total of 150 grams...

100% = 150

1% = 150 ÷ 100 = 1.5

Find out 80% of the bag which is finding out how many raspberries there are in the bag.

80% = 1.5 x 80 = 120

The remaining in the bag out of the raspberries is the berries.

150 - 120 = 30 (berries)

step-by-step explanation:

no of data

divide by no of mode

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
