For every 3 green grapes there are 4 black grapes.

There are 24 green grapes, which is 3*8, so there must be 4 * 8 = 32 black grapes.

Answer:

32

Step-by-step explanation:

Given: In a bowl of fruit, there are green grapes and black grapes in the ratio of 3:4 in there are 24 green grapes.

To Find: how many black grapes are there.

Solution:

The ratio of green grapes and black grapes is 3:4

Let the number of green grapes in bowl be =3\text{x}

Therefore

Number of black grapes are =4\text{x}

now,

Number of green grapes are =24

3\text{x}=24

\text{x}=8

Number of black grapes are =4\text{x}

                                               4\times8

                                               32

hence the total number of black grapes in bowl of fruit is 32.

21.

So to solve for the value of a variable in an equation, you would need to isolate x on one side. The first thing you have to do is multiply 2 and (x + 7) together, which can be rewritten as 2(x) + 2(7). After multiplying, your equation would be: 2x+14+3x=12 , or A.

22.

So the rule with multiplying exponents with the same base is to add the exponents together, and the rule with dividing exponents with the same base is to subtract the exponents. Your equation will be simplified as such:

4^{(3+4)-9}\\ 4^{7-9}\\ 4^{-2}

Now the rule with converting negative exponents into fractions is x^{-m}=\frac{1}{x^m} . In this case, 4^-2 would turn into \frac{1}{4^2} , or C, which is your final answer.
