6 times a larger number (so 6y) is equal (=) to the sum of a snaller number and 18 (x+18)

6 0

6y = x + 18
2y = x + 6 subtract :-

4y = 12
y = 3

substitute y=3 into second equation:-
6 = x + 6
so x = 0

solution is x=0.y=3

I'm not sure what techniques you've been looking at to solve a system like this, but substitution would be a good one to use. Solve one of the equations for one of the variables (pick an easy one). How about using the first equation and solving for x:
6y = x + 18
x = 6y - 18
Now, plug in the expression for x into the other equation:
2y - (6y - 18) = 6
Solve that for y, then use the answer to find x.

The greatest number of bat bags the coach can buy with $605 is

Studentka2010 [4]

Answer:

does not

Step-by-step explanation:

If we know how much money the coach has and how much each bag costs we can find out how much bags the coach can by by divide the money the coach has by the price of one bat bag. So we do....

605 / 55 = 11

So now we know that she can by 11 bags maximum, while she needs 12 bags for the team. From this we know that she does not have enough money to buy 12 bags.

3 Terrence uses pieces of wood that are 10 inches long to

Alchen [17]

Answer:

146 whistles

Step-by-step explanation:

First, convert 122 feet to inches, by multiplying it by 12

122(12)

= 1464

Divide this by 10 to find how many whistles he can make

1464/10

= 146.4

Since we can only have a whole number of whistles, we have to round down to 146.

So, he can make 146 whistles

Given in the figure below, find the values of X and Z.

Answer:

$\boxed{x=9}\\\boxed{z=76}$

Step-by-step explanation:

Hello There!

Geometry

The angles shown represented by the expressions (11x + 5) and (5x+59) are vertical angles

Vertical angles are congruent so we can use this equation to solve for x

Basic Algebra

11x + 5 = 5x + 59

step 1 subtract 5x from each side

5x - 5x cancels out

11x - 5x = 6x

now we have 6x + 5 = 59

step 2 subtract each side by 5

5 - 5 cancels out

59 - 5 = 54

now we have 54 = 6x

step 3 divide each side by 6

6x/6=x

54/6=9

we're left with x = 9

now we want to plug in 9 into x for one of the expression

11(9) + 5

11 * 9 = 99

99 + 5 = 104

so we can conclude that the measure of the angle labeled ( 11x + 5 ) is 104 degrees

Now we need to find z

Geometry

The angle with a measure of 104 and angle Z are supplementary angles meaning that the sum of the two is 180

So to find z we subtract the known angle (104) from 180

180 - 104 = 76

so we can conclude that z = 76
