Using the expression 7x = 3y is 35, what is x?

Romashka-Z-Leto [24]

7x = 3y

y = 35

plug in 35 for y

7x = 3(35)

simplify, multiply 3 and 35 together

3(35) = 105

7x = 105

isolate the x, divide 7 from both sides

7x/7 = 105/7

x = 15

15, A is your answer

For #2:

Bruce has 97 sports card. 34 are football cards. Find y, which are the amount of sports cards not foot ball cards

34 + y = 97

34 (-34) + y = 97 (-34)

y = 97 - 34

y = 63

PLEASE HELP MEEEEEEEEE

Serggg [28]

Answer:

3 pieces

Step-by-step explanation:

Key skills needed: Division

1) Rudolph has a $9\frac{1}{2}$ ft. long piece of wood.

2)He want to divide it into $2\frac{3}{4}$ ft. pieces.

3) To find out the maximum number of piece he can make you have to do:

$9\frac{1}{2}$ ÷ $2\frac{3}{4}$ --> Convert both to improper form --> ( 9 1/2 is 9x 2 + 1 = 19/2) & (2 3/4 is 2 x 4 + 3 = 11/4) This means it would be: $\frac{19}{2}$ ÷ $\frac{11}{4}$ .

Dividing by a fraction is the same multiplying by it's reciprocal (The reciprocal of 11/4 is 4/11) so it would be $\frac{19}{2}$ x $\frac{4}{11}$ = $\frac{76}{22}$ ---> $3\frac{10}{22}$

The answer above means Rudolph can cut only 3 pieces, and then he will be left with a little chunk of wood, but that is not big enough to be counted as a whole piece.

Therefore, the answer is 3 pieces

Hope you understood and have a nice day!! :D
