Step-by-step explanation:
-3+5=-10
−3x+5−5=−10−5
−3x=−15
−3x÷−3=−15÷-3
x=5
(-2 4/5)(1 4/5)
=-14/5×19/5
=-14×9/5×5
=-126/25
=-5 1/25
Answer:
3. x = 5
4. -5 1/25
Step-by-step explanation:
Question 3 Solving:
your equation is -3x + 5 = -10
subtract 5 from both sides to get the term with x alone: -3x = -15
divide both sides by -3 to isolate x (remember that a minus divided by minus is plus): x = 5
To check:
plug in 5 to x and see if you get -10 on both sides
-3(5) + 5 = -10
first multiply -3 and 5:
-15 + 5 = -10
then add 5 to -15:
-10 = -10
if the number are equal then you solved the equation correctly
Question 4:
multiply the whole number by the denominator, then add the numerator to the product, and that number will be your new numerator ( make sure to leave the negative sign out of this computation)
so multiply 2 and 5 to get 10, then add 4 to get 14
your new fraction is -14/5
practice doing the same thing to the other mixed fraction
you should get a new fraction of 9/5
multiply the numerators and denominators
so multiply -14 and 9, and multiply 5 and 5
you now have -126/25
divide 126 by 25 to get your whole number of the mixed fraction
you should have -5 ?/25
to find the numerator, multiply your whole number by your denominator (25 x 5 = 125), then subtract this from your numerator of the improper fraction
126-125 = 1
now you have an answer of -5 1/25

Answer:
a) Center of dilation (0,0)
b) Scale factor = 2
Step-by-step explanation:
Dilation of Polygons
The triangle ABC has its vertices at A(-2,2), B(4,2), and C(-2,-2).
The triangle A'B'C' has its vertices at A'(-4,4), B'(8,4), and C'(-4,-4).
Since A'B'C' is a dilation of ABC, we check if all its vertices are proportional with the same scaling factor.
Both vertices of A' are twice the vertices of A: (-4,4)=2*(-2,2)
Both vertices of B' are twice the vertices of B: (8,4)=2*(4,2)
Both vertices of C' are twice the vertices of C: (-4,.4)=2*(-2,-2)
a)
The proportionality of the coordinates of the vertices tells us the center of dilation must be the origin of coordinates (0,0).
b)
The scale factor is the constant number all the vertices are multiplied by, that is, scale factor = 2
I will give you brainliest if you figure this out

An image shows three groups of three tenths and two hundredths.
Which of the following explains the mistake Jill made?
A.
Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.
B.
Jill used groups of 3 tenths and 2 hundredths rather than groups of 4 tenths.
C.
Jill used 3 groups of 3 tenths and 2 hundredths rather than 2 groups.
D.
Jill used groups of 3 tenths and 2 hundredths rather than groups of 3 tenths and 8 hundredths.
Answers
Answer:
A.
Step-by-step explanation: By looking at the image it shows 2 not 4.
The only option that explains the mistake Jill made in the model is;
Option A; Jill used 3 groups of 3 tenths and 2 hundredths rather than 4 groups.
The model Jill made is to show the quotient of 1.28 ÷ 4.
Now, this means she wants to divide 1.28 into 4 equal parts. Thus, the model must show 4 identical quotients.
The image of the model we are seeing from Jill is showing;
3 groups of 3 tenths and 2 hundredths.
Since it is showing 3 groups instead of 4 groups, the it is clear that Jill made a mistake in her model.
In conclusion, the only option that identifies the mistake correctly is option A.

Two angels of a triangle measure 12 and 40.

C) 128
Step-by-step explanation:
Sum of all three angles of triangle = 180
Let the third angle be 'x'
x + 12 + 40 = 180
x + 52 = 180
x = 180 - 52
x = 128

The correct option is;
26.8
Step-by-step explanation:
The given parameters are;
The perpendicular bisectors of the sides of ΔMNP = Segments OQ, OR, and OS
Therefore;
in Segment MN, segment QM = segment QN, by definition of bisected line
Segment OQ = Segment OQ by reflexive property
∠OQM = ∠OQN = 90° by definition of perpendicular bisector
∴ ΔOQN ≅ ΔOQM, by SAS rule of congruency
Segment MO ≅ Segment ON by Congruent Parts of Congruent Triangle are Congruent, CPCTC
Segment MO = Segment ON = 26.8, by definition of congruency
Segment MO = 26.8

The corner market sells potatoes at a rate of 1/2 dollars per potato.
1. Amanda is only able to spend $5 on potatoes. What is the most number of potatoes she can buy?
2. Sam wants to buy 15 potatoes. How much will that cost him?
Answers
Answer:
The cost of 15 potatoes is $7.50
Step-by-step explanation:
The potatoes are sold at a rate of $0.5 per potato.
1. Given Amanda can only spend $5 on potatoes at that price, she can buy at most $5 / 0.5 = 10 potatoes.
Amanda can buy at most 10 potatoes
2. Sam wants to buy 15 potatoes at that very same price. The cost of 15 potatoes is:
15 * $0.5 = $7.50
The cost of 15 potatoes is $7.50
