Answer:
-10, 5,-1
Step-by-step explanation:
Set each parentheses to 0
x+10=0 then factor 10 over
x=-10
repeat
x-5=0 to x=5
x+1=0 to x=-1
-2.5x - 10 = 40 what is the missing variable
Answer:
x = -20
Step-by-step explanation:
1) Isolate x
-2.5x - 10 = 40
+ 10 + 10
-2.5x = 50
------- ------
-2.5 -2.5
x = -20
Answer:
x=-20
Step-by-step explanation:
-2.5x -10=40
-2.5x -10+10=40+10
-2.5x=50
-2.5x/-2.5=50/-2.5
x=-20

What is the solution to this system of equations?
x= 12 - y
2x + 3y= 29
ОА.
x = 8, y=4
B.
x = 6, y = 6
O C. x = 7, y= 5
OD
x = 9, y = 3
Answer:The answer is C
Step-by-step explanation:
When you plug it in 7*2 is 14+ 5*3 is 15 you add 14+15 you get 29 and then for the other equation you do 12-5 which gives you the x value of 7. Hope this helps.
A scale on a map shows that 2.5 centimetres represents 15 kilometres what number of actual kilometres are represented by 17.5 centimetres on the map
Answer:
105km
Step-by-step explanation:
From the above question, the scale is
2.5 cm = 15km
Therefore,
17.5 cm = x
We Cross Multiply
2.5cm × x = 15km × 17.5 cm
x = 15km × 17.5cm/2.5
x = 262.5/2.5
x = 105 km
Therefore, the number of actual kilometres that are represented by 17.5 centimetres on the map is 105 kilometres.

Choose the ordered pair which is the solution to: -2x + 7y = 17 and 3x - 4y = -19.
O (0,17/7)
O (-1,-2)
O (-5,1)
O (-1,3)
9514 1404 393
Answer:
(-5,1)
Step-by-step explanation:
To eliminate x, multiply the first equation by 3 and add 2 times the second equation.
3(-2x +7y) +2(3x -4y) = 3(17) +2(-19)
-6x +21y +6x -8y = 51 -38
13y = 13
y = 1 . . . . . matches the third answer choice
(x, y) = (-5, 1)
There were 7,313 more searches in the library book checkout system in January than February. In February there were 8,972 searches, how many searches were done in both months?
Given:
Searches in February = 8972
There were 7,313 more searches in the library book checkout system in January than February.
To find:
The searches in both months.
Solution:
Searches in February = 8972
There were 7,313 more searches in the library book checkout system in January than February. So,
Searches in January = 8972 + 7313 = 16285
Now,
Total number of Searches in both months = January + February searches
[tex]=16285 + 8972[/tex]
[tex]=25257[/tex]
Therefore, total number of searches in both months is 25257.

Marie can find the volume of a cube by using the formula V=s exponent 3 where s repersents the side length of the cube if marie's cube has a side length of 2-1/2 centimerters what is the volume of her cube? WRITE AS A FRACTION
Answer:
125 / 8 centimeters
Step-by-step explanation:
Given:
V = s³
Where,
V = volume of the cube
s = side length of the cube
if marie's cube has a side length of 2 1/2 centimerters
That is,
s = 2 1/2 cm
V = s³
= (2 1/2)³
= (5/2)³
= 125 / 8 centimeters
NOTE:
(5/2)³ = 5³ / 2³
= 5*5*5 / 2*2*2
= 125 / 8
how do I solve an equation with different variables on both sides? here is an example.
solve for x
9x – 2c = k
Answer:
Step-by-step explanation:
9x - 2c = k
9x = k + 2c
x = (k + 2c)/9
five more than the quotient of a number and 6 is 30
Answer:
x = 150
Step-by-step explanation:
5 + x ÷ 6 = 30
x / 6 = 30 - 5
x / 6 = 25
x = 25 x 6
x = 150

Identify the most precise name for the angle pair shown in the picture.
Answer:
I think its complementary
how much is the arc of a circle if the angle is 70°
Answer:
siriously i dont know cuz im learning this in maths
area
perimeter
arc
Answer:
We also know that the sum of the measures of arcs AD, AB, CD, and BC must be 360 degrees, because there are 360 degrees in a full circle. Because AD = 2AB, we can substitute 2AB for AD. This means the measure of arc AB is 70 degrees, and the measure of arc AD is 2(70) = 140 degrees.

Car Survey in a survey of 1,800 people who owned a certain type of car, 1,080 said they would buy
that type of car again. What percent of the people surveyed were satisfied with the car?
Answer: 60%
Step-by-step explanation:
First you have 1,080 satisfied out of 1,800.
Then you divide 1,080/ 1,800.
When you divide you get .6
Finally move the decimal 2 places to the right and you get 60 which is 60%.

Answer:
15) 3(4+r)=-18
3x4+3xr
12+3r= -18
-12 -12
3r= -30
/3 /3
r= -10
Step-by-step explanation:
distribute the 3 to the 4 and the r you should then have 12+3r=-18 and so subtract from both sides 12 and you should have 3r=-30 divide both sides by 3 and you get your answer r=-10
