2.3 : 2.2
Given:3x : 5y and 7 : 11
Step-by-step solution:3x : 5y
7 : 11
To find x:
3x = 7
x = 7/3 (Bring 3 over to 7 to divide)
x = 2.3 OR 2/1/3
To find y:
5y = 11
y = 11/5 (Bring 5 over to 11 to divide)
y = 2.2 OR 2/1/5
So,
x = 2.3
y = 2.2
Therefore, the answer is:
x : y = 2.3 : 2.2

Write the product using exponents. Use^ to indicate raising the number to a power.
Use parentheses but do not type spaces.
(-6)(-6)
Answer:
(-6)^2
Step-by-step explanation:
(-6)(-6) is the same as saying (-6) x (-6) which equals to 36. (-6) to the second power is what (-6)^2 means. The two is the exponent.

5. Carlos collected tickets to concerts he went to. This year he went to 4 concerts. He has now been to 17 concerts. If zequals the number of concerts he had been to before this year, which expression represents this situation? A t = 17+ 4 Bt=4 - 17 C. 17 = t + 4 D. 4 = t + 17
Answer:
The answer is 17=t
Step-by-step explanation:
If you add the tickets you get 17=t. Good luck.

what is 6x - 12 = 30
Answer:
x = 7
step by step:
6x - 12 = 30
add 12 to the other side to start to get x by itself on one side
6x = 42
divide by 6 on both sides to get x completely by itself
x = 7

A printer is printing photos. For every 15 photos, the printer takes 3 minutes.
Complete the table below showing the number of photos and the time it takes to print them.
Answer:
20, 6, 45, 10
Step-by-step explanation:
each minute is 5 papers so 3 min is 15 then 4 min is 20 papers
Answer: Number of photos: 15,25,35,40,50
Time: 3,5,7,8,10
Step-by-step explanation:
To find the time we divide the number of photos by 5. To find the number of photos we multiply the time by 5.when the number of photos is 35, the time is 35 divided by 5 which equals 7 minutes.

Answer:
Saturday: 1.5x
Sunday: 2x
Step-by-step explanation:
For the the Chart, Saturday, we can automatically see that when 1 is inputted into the equation we get 1.5, as anything times 1 will equal the same number inputted (x). So we can try 1.5x and plug in every other x value and see what we get:
1.5(2) = 3
1.5(3) = 4.5
1.5(4) = 6
This verifies that the equation 1.5x works with this chart.
For the graph its simple, do rise over run and your slope is 2/1 which is 2 so we have 2x for our equation so far and now to find the + or - at the end of the equation ( the "b" variable of the mx + b form) we just look at where does the function intersect with the Y-axis. Since it is at 0 we don't need to add a "b" variable to the equation so the equation for the graph is 2x for Sunday.

[tex]\huge\boxed{\tt{x = -5 , y = 2}}[/tex]
Step-by-step explanation:
x = y - 7 ---------------------(1)
-y - 2x = 8 --------------------(2)
Put Equation (1) into (2)
- y - 2 ( y-7 ) = 8
-y - 2y + 14 = 8
-3y = 8 - 14
-3y = -6
Divide -3 to both sides
y = -6 / -3
y = 2
Put y = 2 in (1)
x = 2 - 7
x = -5
So,
x = -5 , y = 2

The length of which line segment is equal to the exact value of the sine if theta?
Option 3: line segment OR
Option 4: line segment OS
====================================================
Explanation:
Recall that the sine of an angle is equal to the ratio of opposite over hypotenuse.
In other words,
sin(angle) = opposite/hypotenuse
With respect to reference angle theta, the side TS is opposite this angle. It is the leg furthest from the angle. The hypotenuse is the longest side segment TO. The hypotenuse is always opposite the 90 degree angle.
For a unit circle, the radius is 1, so segment TO is 1 unit long.
Therefore,
sin(angle) = opposite/hypotenuse
sin(theta) = TS/TO
sin(theta) = TS/1
sin(theta) = TS
