Answer:
5x+10y+5z
Step-by-step explanation:
Distributive Property means you multiply each component by the value you are distributing in this case: (1/2)(10x) + (1/2)(20y) + (1/2)(10z) which will yield 5x+10y+5z

Teachers divided students into groups of 3. Each group of 3 wrote a report that had 9 pictures in it. The students used 585 pictures altogether. How many students were there in all?
Answer: 195
Step-by-step explanation:
585/9=65
65*3=195
Answer:
The answer is 195 students.
Step-by-step explanation:
There are 2 solutions for this.
1st solution.
1. Start with the basics, the number of pictures we have altogether, 585.
2. Divide the number 585 by the number of students which is 3 to identify the total number of students that reported the 585 pictures.
3. 585/3 = 195, the total number of students.
2nd solution.
1. Start with the total again, the number of pictures we have altogether, 585.
2. Divide the number 585 by the number of pictures in each group total received pictures which is 9.
3. 585 divided by 9 = 65.
4. Take the number 65 which is the number of groups and multiply it by 3 the number of students in each group which will lead to the answer 195 again.
5. 195 is the number of students in total.
6. Extra: to even re-check your answers, multiply 195 by 3 and u will get 585, because each student did 3 reports.

What is 5/3s+19/15= -3/5?
Answer:
I hope I didn't make mistakes, because I solved it without calculator
Step-by-step explanation:
[tex] \frac{5}{3} s + \frac{19}{15} = - \frac{3}{5} \\ \frac{5}{3} s = - \frac{3}{5} - \frac{19}{15} \\ \frac{5}{3} s = \frac{ - 9 - 19}{15} \\ \frac{5}{3} s = \frac{ - 28}{15} \\ s = - \frac{28}{15} \times \frac{3}{5} [/tex]
[tex]s = - \frac{28}{25} [/tex]
To make 4 batches of cupcakes, it takes 6 cups of flour. How many cups of flour are needed for 1 batch?
Answer:
1.5
Step-by-step explanation:
First you divide 6 by 4. It looks like this 6/4.
Then you get 1.5 cups of flour.
Good Luck!
Answer:
3/2 cups
Step-by-step explanation:
4 batches = 6 cups
1 batch of cupcakes = (6/4) cups of flour.
hence, 3/2 cups of flour are needed for 1 batch.

Answer:
B. 477°, -243°Step-by-step explanation:
Coterminal angles with 117° are:
117° + 360°x, where x is an integerWhen x = 1 and -1 we get:
117° + 360° = 477° and 117° - 360° = -243°It can be easily verified that all the other pairs are incorrect
Correct one is B
You take measurements of the distance traveled by an object that is increasing its speed at a constant rate. The distance traveled d as a function of time t can be modeled by a quadratic function. What is the quadratic function that models distances of 21 ft at 1 s, 59 ft at 2 s, and 141 ft at 4 s?
Answer:
Follows are the solution to this question:
Step-by-step explanation:
Given:
[tex]s_1 = 21 \ \ t_1 = 1\\\\s_2 = 59 \ \ t_2 = 2\\\\s_3 = 141 \ \ t_3 = 4[/tex]
All points are on the graph including its quadratic function, in order to install their coordinates to values of x and y with the following values:
[tex]y= ax^2 + bx + c\\\\21=a+b+c[/tex] Inserting the coordinates of the first point
[tex]y= ax^2 + bx + c\\\\59 =4a+2b+c[/tex] Inserting the coordinates of the second point
[tex]y= ax^2 + bx + c\\\\141=16a+4b+c[/tex] Inserting the coordinates of the third point

Answer:
both are (0,0)
Step-by-step explanation:
Hello There!
When its asking for the vertical intercept its asking " at what points does the equation cross the vertical axis( y axis) so its pretty much asking for the y intercept¨
In the graph shown below the y intercept is 0 so the coordinates of the vertical intercept would be (0,0)
When its asking for the horizontal intercept its asking " at what points does the equation cross the horizontal axis ( x axis ) so its pretty much asking for the x intercept."
In the graph shown below the x intercept is 0 so the coordinates of the horizontal intercept would be (0,0)
awnser the questions to describe the transformations of figure ABCD. Is A'B'C'D' a translation rotation or reflection of abcd?
Answer:
1. Reflection
2. rotation and reflection
3. b', b''
4. 26.3
Step-by-step explanation:
1. It is like looking in a mirror. Its is being reflected across the y axis
2. It is rotated 90 degrees to the right. Then reflected over the x axis.
3. they are the same
4. It is the same as A" B" C" D" so the lengths are the same and you just add them.

-(4k^2-13k-12)+5k^2-8k How would I be able to write this in standard form with the greatest exponent being first.
Answer:
Step-by-step explanation:
Negative sign is outside the parenthesis. So, each term of (4k² - 13k -12) should be multiplied by (-1)
-(4k² - 13k -12) + 5k² - 8k = 4k²*(-1) - 13k*(-1) - 12*(-1) + 5k² - 8k
= -4k² + 13k + 12 +5k² - 8k
Combine like terms,
= -4k² + 5k² + 13k - 8k + 12
= k² + 5k + 12
Like terms are the terms with same variable with same exponent.
(-4k² ) and 5k² are like terms
13k and (-8k) are like terms
