Answer:

a/2=3

We simplify the equation to the form, which is simple to understand  

a/2=3

We move all terms containing a to the left and all other terms to the right.  

+ 0.5a=+3

We simplify left and right side of the equation.  

+ 0.5a=+3

We divide both sides of the equation by 0.5 to get a.  

a=6

Answer:

35

Step-by-step explanation:

3 1/2 x 10 =35

make 3 1/2 into an improper fraction: 3 x 2 + 1 = 7/2

make 10 into a fraction: 10/1

find the LCD (least common denominator) for each number:

10/1 = 20/2

7/2 = 7/2

20/2 x 7/2 = 70/2 = 35

:)

Answer:

35

Step-by-step explanation:

For 1 cup of flour, you make 10 muffins. Just by reading the problem, you see that the number of muffins, 10, is 10 times the number of cups of flour, 1.

For 3 1/2 cups of flour, you make 10 times that number muffins.

3 1/2 × 10 = 3.5 × 10 = 35

Answer: 35 muffins

You can also use a proportion.

1 cup flour is to 10 muffins as 3.5 cups flour is to x muffins.

1/10 = 3.5/x

Cross multiply:

1 × x = 10 × 3.5

x = 35

Answer: 35 muffins

Answer:

b = c/3 + 2/3

Step-by-step explanation:

3b - 4/2 = c

the goal is to have b all by itself on one side of the equals sign.

start by moving the fraction over to where c is by adding.

3b = c + 4/2

adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.

Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)

b = c/3 + 2/3

notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3

Answer:

Drew = 92 pictures, Danielle = 26 pictures

Step-by-step explanation:

Amount of pictures Drew has = x

Amount of pictures Danielle has = y

First make a system of equations:

x + y = 118

x = 3y + 14

Then solve with substitution:

(3y + 14) + y = 118

4y = 104

y = 26

x + 26 = 118

x = 92
