Answer:
37 and -18
Step-by-step explanation:
Let one number be x and other y
1 x + 1 y = 19 .............1
1 x -1 y = 55 .............2
Eliminate y
multiply (1)by 1
Multiply (2) by 1
1 x 1 y = 19
1 x + -1 y = 55
Add the two equations
2 x = 74
/ 2
x = 37
plug value of x in (1)
1 x + 1 y = 19
37 + 1 y = 19
1 y = 19 -37
1 y = -18
y = -18
37 and -18
TIME REMAINING 24:59 Ten members of Balin's soccer team ran warm ups for practice. Each member ran the same distance. Their combined distance was StartFraction 5 Over 6 EndFraction of a mile. To find the distance that each member ran, Balin wrote the expression below. StartFraction 5 Over 6 EndFraction divided by 10 Which expression is equivalent to Balin's expression?
Answer:
The equivalent expression = 1/12 of a mile
Step-by-step explanation:
Total distance of 10 members of the Balin's soccer club =5/6 of a mile
To find the distance that each member ran, Balin wrote the expression:
5/6 ÷ 10
Which expression is equivalent to Balin's expression?
5/6 ÷ 10
= 5/6 × 1/10
= 5/60
= 1/12 of a mile
Each member of the Balin's soccer club ran 1/12 of a mile
The equivalent expression to 5/6 of a mile divided by 10 members of the Balin's soccer club is 1/12 of a mile

Answer:
1/ 2.5
Step-by-step explanation:
one way to do this is rise over run, so from one red dot to the other it went up one and over 2.5. the other way to do this is by using the (y2-y1)/(x2-x1) this will give you the same answer :)

Find the slope between (9,-2) and (-1,5)
Answer:
7/-10
Step-by-step explanation:
subtract
5-(-2) = 7
-1-9 = -10
Answer:
The slope is -0.7 or -7/10
Step-by-step explanation:
For 10 x values decreased, the y values go up 7 values. So the slope is -7/10 or -0.7

The indoor climbing gym is a popular field trip destination. This year the senior class at High
School A and the senior class at High School B both planned trips there. The senior class at High School A rented and filled 14 vans and 5 buses with 329 students. High School B rented and filled 11 vans and 5 buses with 281 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.
Answer:
Step-by-step explanation:
14 x + 5y = 329
11x + 5y = 281(vans is x and busses are y)
cancel out 'y' by making the '5y' in 11x + 5y = 281 negative
-1 (11x + 5y = 281) =
-11x -5y = -281
insert second equation
-11x -5y = -281
14x + 5y = 320
3x = 48
x = 16
substitute vans in one equation
11(16) + 5y = 281
5y = 105
y = 21

3(2x-5)=-15
Answer:
x=0
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
3(2x−5)=−15
Step 1: Simplify both sides of the equation.
3(2x−5)=−15
(3)(2x)+(3)(−5)=−15(Distribute)
6x+−15=−15
6x−15=−15
Step 2: Add 15 to both sides.
6x−15+15=−15+15
6x=0
Step 3: Divide both sides by 6.
6x/6 = 0/6
x=0

So how are 1/2 and 4/8 Similar?
Answer:They both equal 1 half
Step-by-step explanation:To put it a lil more simply, 1/2 = 0.5 and 4/8 also = 0.5
Answer:
1/2 is 4/8. 1/2 is just 4/8 but simplified. So 12/36 simplified is 1/3, 24/48 is 1/2
Nathan spins 2 different spinners at the same time. There are a total of 10 possible outcomes. Which pair of spinners did Nathan spin? A B 1 2. AB E с 5 3 E с 1 2 D 4 D А B B 1 2 care 1 2 E с D с D 3
Answer:
Since the spinners have been spun simultaneously, every side on each of the spinner carries equal probability of landing. In order for there to be only 10 possible outcomes, no more no less, the spinners cannot be identical. One of the spinner in two sided while the other spinner must then be a five sided spinner. Choosing this particular pair of spinners gives Nathan 10 possibilities of combinations.

Answer:
Parallel line - y=6x+9
Perpendicular line - y=-1/6x +4
Step-by-step explanation:
Parallel lines have a slope that is equal to the origninal equation. You use the y-y1=m(x-x1) equation. In this case, your y1 is 3 and your x1 is -1. Plug these into the equation along with your slope of 6.
y-y1=m(x-x1)
y-3=6(x-(-1))
y-3=6(x+1)
y-3=6x+6 - Distribute
+3 +3 - Add 3 to both sides
y=6x+9
For perpendicular lines, the slope is the negative reciprocal of the given slope. In this case, the slope is -1/6. Your y1 is 4 and your x1 is 0.
y-y1=m(x-x1)
[tex]y - 4 = - \frac{1}{6} (x - 0)[/tex]
Distribute:
[tex]y - 4 = - \frac{1}{6} x[/tex]
+4 +4
Add 4 to both sides:
[tex]y = - \frac{1}{6} x + 4[/tex]
A 12- pack of 8- ounce juice boxes costs $5.90. How much would an 18- pack of the same 8- ounce juice boxes cost?
Answer:
$8.85
Step-by-step explanation:
This a question of direct variation, so we can make out a relationship between the two factors. 12 is 2/3 of 18, so the cost of 12 would also be 2/3 of the cost of 18. We can now make an equation to solve.
[tex]\frac{2}{3} x=5.9\\2x=17.7\\x=8.85[/tex]
The Bigtown football team outscored its opponents 5:2 last season.
If their opponents scored 38 points, how many points did Bigtown
score?
Step-by-step explanation:
5:2 add to find total ratios 7
opponents=2/7=38
bigtown=5/7=95
Answer: The big town team scored 95 points.
Step-by-step explanation: Given that the big town football team outscored its opponents 5:2 last season and their opponents scored 38 points.
We are to find the points scored by big town team.
Let 5x and 2x represents the points scored by big town team and their opponents.
Then, according to the given information, we have
2r = 38
r = 38/2
r = 19
Therefore, the points scored by big town team is given by
5 X 19 = 95.
Thus, the big town team scored 95 points.
