Split 33 into two numbers that when added up are 33.
So 12 to 21, which when divided by 3, are 4 to 7.

Answer:

Group #1: 12

Group #2: 21

Step-by-step explanation:

The ratio is 4:7 which means for each 4 elements in group number one we would have 7 elements in the group number 2. This gives us a total of 11 elements but the total is 33, so we do it again two more times to get the total of 33 elements (11x3=33) so now we know we have to multiply 3 times the ratio to get the correct answer like this

4(3):7(3)

12:21

Proof:

4+7=11

4+7=11

4+7=11

4+4+4=12

7+7+7=21

11+11+11=33

12+21=33

Tammy has scored 82, 78, and 93 on her previous three tests. What score does she need on her next test so that her average (mean
Lyrx [107]

Answer:

She needs a grade of 71 on her next text.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is the sum of all values in the data-set divided by the number of values.

Tammy has scored 82, 78, and 93 on her previous three tests.

Thus, her grades are 82, 78, 93 and x, in which x is her grade in the fourth test.

There are 4 tests.

What score does she need on her next test so that her average (mean) is 81?

We have to find x when the mean is 81. So

\frac{82 + 78 + 93 + x}{4} = 81

253 + x = 324

x = 324 - 253

x = 71

She needs a grade of 71 on her next text.

Solve the equation<br> 13-4x=1-x
dem82 [27]
Add 4x to both sides and get
13 = 1 + 3x
12 = 3x   [from subtracted 1 from both sides]
x = 4      [from dividing 3 from both sides]

therefore your answer would be  x = 4
