Multiply numbers
A/4 -1 x 5/6 = -1/2
A/ 4 - 5/6 =-1/2
Add 5/6 to both sides of the equation
A/4 -5/6 =1/2
A/4 -5/6+5/6 =-1/2 +5/6
Simplify
Add the numbers
A/4 =1/3

Multiply all terms by the same value to eliminate fraction denominators
A/4 = 1/3
4x a/4 =4x1/3
Simplify

Cancel multiplied terms that are in the denominator
Multiply the numbers
A=4/3
Solution
A=4/3

Answer:

Step-by-step explanation:

Change the denominator of the 1/2 to sixths. Multiply the top and bottom by 3 to get 3/6

\frac{a}{4}-\frac{5}{6}=-\frac{3}{6}   \\

Add 5/6 to both sides and simplify

\frac{a}{4} =\frac{1}{3}

Multiply both sides by 4 to get

a=4/3

Find the gcf of 6, 15, and 36. a. 2 b. 3 c. 6 d. 180
zlopas [31]
To find the GCF, you find the prime factors that have a product of each number. Then, you can compare and see which numbers there are in common.

6=2x3
15=3x5
36=2x2x3x3

Here, the only common factor is 3, therefore the answer is b.

Amanda, Lisa, and Raquel together sold 54 tickets for the school play. Amanda sold 22 tickets and Lisa sold 14 tickets. How many
mario62 [17]
Question 1. Raquel sold 18 tickets since if you do 54-22-14 you would get 18
Question 2. 14+28= j since 14 is the number of beans his mother put in the bag and j is the total amount afterward
Question 3. The answer is 49, simply solve for x by subtracting 14 on both sides
Question 4. You can add 4 blocks to the right or take away 3 blocks from the left since they will then have an equal amount of blocks
Question 5. The answer is 27.6, like question 3 solve for x by subtracting 8.6 on both sides
Question 6. The answer is $8.18, do this by subtracting 3.87 and 5.95 from 18 and the remainder would be the cost of the magazine

In 1998, Cathy's age is equal to the sum of the four digits in the year of her birthday, then how old was Cathy in 1998?
ycow [4]

Answer:

<em>Cathy was born in 1980 and she was 18 years old in 1998</em>

Step-by-step explanation:

<u>Equations</u>

This is a special type of equations where all the unknowns must be integers and limited to a range [0,9] because they are the digits of a number.

Let's say Cathy was born in the year x formed by the ordered digits abcd. A number expressed by its digits can be calculated as

x=1000a+100b+10c+d

In 1998, Cathy's age was

1998-(1000a+100b+10c+d)

And it must be equal to the sum of the four digits

1998-(1000a+100b+10c+d)=a+b+c+d

Rearranging

1998=1001a+101b+11c+2d

We are sure a=1, b=9 because Cathy's age is limited to having been born in the same century and millennium. Thus

1998=1001+909+11c+2d

Operating

88=11c+2d

If now we try some values for c we notice there is only one possible valid combination, since c and d must be integers in the range [0,9]

c=8, d=0

Thus, Cathy was born in 1980 and she was 18 years old in 1998. Note that 1+9+8+0=18

A positive integer is 11 more than 18 times another. Their product is 6030. Find the two integers.
allsm [11]

Answer:

18 and 335

Step-by-step explanation:

y = 18x + 11

x * y = 6030

x * (18x + 11) = 6030

18x^2 + 11x = 6030

18x^2 + 11x - 6030 = 0

(18x + 335)(x - 18) = 0

18x + 335 = 0                 x - 18 = 0

18x = -335                      x = 18

x = -335/18

x is gonna have to be a positive number...so x = 18

y = 18x + 11

y = 18(18) + 11

y = 324 + 11

y = 335

so ur numbers are 18 and 335
