Answer:
let the $12 dish be x and the other y
x + y = 12 <--- 1
12x + 10.50y= 138 <--- 2
multiply equation 1 by 12
so now we have
12x + 12y = 144
12x + 10.50y = 138
now subtract each one and that cancels out x
1.5y = 6
y = 4
now subsitute that into any equation
x + 4 = 12
x = 12 - 4
x = 8

Finding slope:
Take two pairs of cordinate points from the table and use the formula y2-y1 divided by x2-x1
I choose (4,3) and (2,2)
2-3 divided by 2-4
= -1/2
Then to get the y intercept you use the formula: y=mx+b
For the x and y pick a cordinate to plug in. For m plug in your slope.
I pick (6,4)
4=-1/2×6+b
Multiply -1/2 and 6 to get -3 and plug that in
4=-3+b
Now add 3 to the -3 canceling that out to 0 and add three to the 4 making that 7
7=b
Y-intercept =7
Now plug in the slope and y-intercept into the slope intercept format and get:
Y=-1/2x+7

jack has $7.55 of change in his pocket. if he has 4 more dimes than than nickels, and twice as many quarters as nickels, how many of each coin does jack have
Answer:
11 nickels, 15 dimes, 22 quarters
Step-by-step explanation:
number of nickels = x
number of dimes = x+4
number of quarters = 2x
- - - - - -
total of nickels = 5x cents
total of dimes = 10x + 40 cents
total of quarters = 50x cents
- - - - - -
755 = 5x + 10x + 40 + 50x
755 = 65x + 40
715 = 65x
x = 11
x+4 = 15
2x = 22

Find the area of the shaded region
Answer:
35
Step-by-step explanation:
Here, the shaded region is equal to the non-shaded triangle. To know why this is, look at the formula for a triangle: A = b*h/2. But if we look further, we also know that the area of a rectangle is A = b*h. So the area of a rectangle is twice that of a triangle. And this is always true as long as the dimensions are the same. So here, the shaded region is just (14*5)/2 which is 35. We can also find this out by calculated the area of a rectangle and minus the area of the rectangle.
Please help with the middle question!!
Answer: D) The relation R is a function because for each input there is exactly one output
There's not much else to say other than what choice D already does. Visually we can use the vertical line test to confirm if we have a function or not. If we can pass a single vertical line through more than one point on a curve, then the curve isn't a function. The graph is said to have failed the vertical line test. Otherwise, the relation passes the vertical line test and we have a function.

In the diagram, △ABC ~ △DEF. What is AC?
The image is of two similar right triangles ABC and DEF with right angles at B and E respectively. First one smaller in size and its base is 3. Base, altitude and hypotenuse of second one are 6, 8 and 10 respectively.
A. 4
B. 7.5
C. 5
D. 3
Answer:5
Step-by-step explanation: If you look at the base of both triangles, you'll notice that the smaller one has a base of 3, and the bigger one has a base of 6. The smaller triangle is half of the big one, therefore we can safely say that the hypothenuse of the smaller triangle is half of that of the larger one. Half of 10 is 5.

By 2016 the money spent on internet advertising in the country was projected to exceed the amount spent on tv advertising if it is estimated that 0.6 million dollars more will be spent on internet advertising and 2016 and the total amount spent on internet and tv advertising is expanded to be 150 billion dollars find the amount of money for projected to be spent on each medium
Answer:
$150 billion in total will be spent on both Internet Advertising and TV Advertising.
$0.6 million more will be spent on Internet Advertising than TV.
Let TV Advertising expenses be x.
Expression will be;
x + (x + 600,000) = 150,000,000,000
2x = 150,000,000,000 - 600,000
x = (150,000,000,000 - 600,000) / 2
TV Advertising = $74,999,700,000
Internet Advertising
= TV Advertising + 0.6 million
= 74,999,700,000 + 600,000
= $75,000,300,000

A jeweler has 160.5 centimeters of gold chain. He will use half of the chain to make a necklace. He will make 5 bracelets with the remaining chain. If each bracelet is the same length, what will be the length of each bracelet in centimeters?
9514 1404 393
Answer:
16.05 cm
Step-by-step explanation:
Each bracelet will be 1/5 of 1/2 of the chain, so is
(1/5)(1/2) = 1/10
of the original length of the chain.
1/10 × 160.5 cm = 16.05 cm . . . length of each bracelet

what is the solution for this problem15=12+32x+10
Answer:
x= -7/32 or -0.21875
Step-by-step explanation:
You can start by adding like terms such as 10 and 12 to get 22.
Subtract 22 from both sides to get -7=32x.
Divide both sides by 32.
x=-7/32 or -0.21875
