(-1)(-1)
(-1)(-1)(-1)
(-1)(-1)(-1)(-1)(-1)
Answer:
Wait like all of them or some? I think it's 3 and 4.
Step-by-step explanation:
You add the two negative (negative + negative =positive). 3 and 4 have an extra left over which makes one negative, unless I did that wrong
Answer: 3 and 4
Step-by-step explanation:
If it is an odd number of (-1)s then it is negative. if it is an even number of them then it is positive.
What is the lowest common denominator of the two fractions? An explanation would help x
Answer: 30
Step-by-step explanation:
9/10 = numerator 9 x 3 = 27 and denominator 10 x 3 = 30
2/15 = numerator 2 x 2 = 4 demoninator 15x 2 = 30
This is to make it easier to subtract with a common denominator
= 27-4/ 30
= 23/30
the lowest common denominator is 30
Answer:
Lowest common denominator are

find x and y?
i dont want to cheat but can anyone tell me how to do it or how to start out
Answer:
x is 13
y is 39
Step-by-step explanation:
Answer:
y= 39 x= 10
Step-by-step explanation:
congruent isosceles triangles
longer sides measure the same 13 and 13 39 and 39 ( y =39)
39/30 = 13/x
cross multiplication:
39x = 13x30
39x = 390

0.5m + 2 = 7.5 please I don’t understand
Answer:0
. 5 + 2 = 7 . 5
1 2 + 2 = 7 . 5
Step-by-step explanation:
Answer:
m = 11
Step-by-step explanation:
0.5m + 2 = 7.5
0.5m + 2 - 2 = 7.5 - 2
0.5m = 5.5
0.5m ÷ 0.5 = 5.5 ÷ 0.5
m = 11

Aaron's family uses 1/2 gallon of milk every 5 days. How many gallons of milk will they use in 30 days?
Answer:
Aaron's family will use 3 gallons of milk in thirty days.
Step-by-step explanation:
1. Multiply the amount of milk (1/2) times the days (30)
1/2 x 30 = 15
2. Divide 15 by 5 (every 5 days)
15 / 5 = 3

A bag contains 37 coins consisting of only dimes and quarters.The total amount of money in the bag is $6.85. How many dimes are in the bag ??
Answer:
16 dimes
Step-by-step explanation:
D=number of dimes
Q=number of quarters
D+Q=37
.25 xQ + .10 x D=6.85
sub Q from first equation
.25(37-D) + .10 x D=6.85
D(.10-.25) + .25 x 37 =6.85
-.15D + 9.25=6.85
D= (6.85-9.25)/(-.15)
D=16

Step-by-step explanation:
3(r+2)+5(2-r) =-32 can someone tell em the answer to that please
Answer:
r = 24
Step-by-step explanation:
3(r+2)+5(2−r)=−32
Step 1: Simplify both sides of the equation.
3(r+2)+5(2−r)=−32
(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)
3r+6+10+−5r=−32
(3r+−5r)+(6+10)=−32(Combine Like Terms)
−2r+16=−32
−2r+16=−32
Step 2: Subtract 16 from both sides.
−2r+16−16=−32−16
−2r=−48
Step 3: Divide both sides by -2.
−2r/-2 = -48/-2
r = 24
Answer: r = 24
3(r+2)+5(2-r) =-32
this equals (if we do the multiplication)
3r+6+10-5r=-32
this equals (if we simplify)
-2r+16=-32
this equals (because we are subtracting from 1 side, we must subtract from the other)
-2r=-48
r=24

Shannon walks 2,500 metres in 1 hour 40 minutes.
How far does she walk in one minute?
Answer:
25m
Step-by-step explanation:
Shannon's rate is 2,500m/100min. Simplifying, we see that this is equal to 25m/1min.
So, she walks 25 m in one minute.

A cube that has a length of 1cm on each side has a volume of 1 cmHow many cubic
centimeters are in 1 cubic meter? (Hint: The answer is not 100.)
Answer:
1 cubic centimetre =1 × 10^-6 cubic metre
Step-by-step explanation:
A cube that has a length of 1cm on each side has a volume of 1 cm. How many cubic centimeters are in 1 cubic meter? (Hint: The answer is not 100.)
From the above question,
Side length of the cube = 1cm
Volume of the cube = (side length)³
= (1cm)³
= 1 cm³
How many cubic centimeters are in 1 cubic meter?
Note that:
100 cm = 1 m
1 cm³ = x m³
1 cm³ = (1/100 × 100 × 100)m³
1 cm³ = 1 × 10^-6 m³
Therefore,
1 cubic centimetre =1 × 10^-6 cubic metre
What is a acute triangle and what do a acute triangle look like?
Answer:
An acute triangle is a triangle with three acute angles. An obtuse triangle is a triangle with one obtuse angle and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry
PLEASE HELP, find the orthocenter of this triangle
Answer:
The orthocenter of a triangle is the point at which the three altitudes of a triangle intersect. This involves creating 3 lines, one from each vertex (K, L, and M) perpendicular to the line segment opposite it, so K⊥LM, L⊥KM, and M⊥KL.
Because these three lines intersect at one point, you only need to do this procedure for two of the three altitudes. Because K and M are on the same Y coordinate (-4), lets do this for LM and KL
First, we need to find the slope of the perpendicular to each line segment, so we need the slope of LM and KL.
The slope is the change in Y over the change in X
Slope LM = 6 -(-4) / 2-7 = 10/-5 = -2
Slope KL = -4-(6) / 4-2 = -10/2 = -5
The slope of a perpendicular line is the negative reciprocal of the slope of the given line, so for
the slope of K⊥LM has to be 1/2 and
the slope of M⊥KL has to be 1/5
Second, the vertex has to be on a line with that slope. So using the point-slope formula
(y-y1) = m(x-x1) , where x1,y1 is a point on the line for each line gives us
K⊥LM: y-(-4) = 1/2(x-4)
M⊥KL: y-(-4) = 1/5(x-7)
Third, find the point on both lines, are where the two equations are equal
So, 1/2(x)-2 = 1/5(x) - 7/5;
5x - 20 = 2x - 14
3x = 6 --> x=2
y+4=-1 --> y=-5

Which ratio is not equivalent to the other three? A 2 3 B 12 15 C 18 27 D 6 9
Answer: B= 12 15
Step-by-step explanation:
The given ratios are
A) 2 3= 2: 3 already in its simplest form
B) 12 15 =12:15 Changing to its simplest form, we divide both by 3 giving us 4:5
C) 18 27 =18: 27 Changing to its simplest form, we divide both numbers by 9 giving us =2:3
D)6 9=6:9 Changing to its simplest form, we divide both by 3 giving us
2:3
Therefore the ratio not equivalent to other three is 12:15
