Answer:
(23/2, 1/2)
Step-by-step explanation:
Let's solve this system through elimination by addition/subtraction:
Divide all three terms of the first equation by 3. This results in the equivalent system
-2x - 2y = 33
2x + 4y = -32
Combining like terms results in:
2y = 1, and so y = 1/2.
Let's use the first equation and y = 1/2 to find x:
-6x - 6(1/2) = 66
This becomes -6x - 3 = 66, or -6x = 69, or x = -69/6 , or x = 23/2
The solution is thus (23/2, 1/2)

For triangle TUV let angle V = 90°.
If angle U = 47° and TU = 13.28, what is the measure of TV
Answer:
TV = 9.71
Step-by-step explanation:
sin 47° = TV/13.28
0.7314 = TV/13.28
TV = 9.71

Picture 1:
To figure this out, notice the pattern happening on x. It's simply counting to four, so the first blank is 1 and the next is 2.
The y coordinates seem to be going up by 9. 27 plus 9 is 36, so the answer to the fourth box is 36.
Another way to see how this is correct is to notice that the x is multiplying by 9 to get y. It works out as you look at it and plug it in!
Picture 2:
Yes, this is a proportional relationship. Since Dennis is adding 3 logs every hour, it is keeping a consistent pattern.
Picture 3:
If Jane is driving 60 miles per hour, the first hour she would've gone 60 miles. After a second hour, she would've gone 120 miles. Multiply 60 to your x coordinates to figure this out. You should get 60, 120, 180, and 240 for each box.

You are having a pizza-making party. You will need 6 ounces of dough and 4 ounces of sauce for each person at the party (including yourself, the host). Once you have a total count of guests, you buy exactly the needed amount of all the ingredients. The dough and sauce that you buy weigh 130 ounces all together.
How many ounces of dough did you buy?
How many ounces of sauce did you buy?
How many guests are coming to the party?
Answer:
78 ounces of dough
52 ounces of sauce
12 guests are coming (not including you)
Step-by-step explanation:
13x6=78
13x4=52
78+52=130 ounces

Solve for x.
Answer must be simplified.
Answer:
x < -9
Step-by-step explanation:
Hi there,
To isolate the variable x, you do the same steps like solving a regular equation.
x + 5 < -4 ← subtract 5 from both sides to make x by itself
x < -9 ← final answer (already in simplest form)
