Step-by-step explanation:
Because the ratio is 5:3:2
There are 150 raisins
And since 2 is one less than 3 my estimate would be subtracting 50 from 150 making there be 100 chocolate chips. Then if the unit is 50, 50 x 5 ( 5 in the ratio) would be 250.

On a coordinate plane, the center of dilation is at (0, 0). Triangle A B C has points (negative 4, 3), (4, 4), and (1, 1). A has the coordinates (–4, 3) and B has the coordinates (4, 4). If DO,1/2(x, y) is a dilation of △ABC, what is true about the image △A'B'C'? Check all that apply.
AB is parallel to A'B'.
DO,1/2(x, y) = (one-half x, one-half y)
The distance from A' to the origin is half the distance from A to the origin.
The vertices of the image are farther from the origin than those of the pre-image.
A'B' is greater than AB.

Answer: uhhhhhh pass
Step-by-step explanation:
A deal is a deal, so here is a good one, let's see who gets it right I had $5.00. My mom gives me $10.00, My dad gave me $30.00. My aunt and uncle give $100.00. I had another $5.00. How much money did I have?
Answer:150.00$
Step-by-step explanation:
The total amount that the person will have is $150.00
Amount that the person had = $5.00 + $5.00 = $10.00Amount given by mum = $10.00Amount given by dad = $30.00Amount given by aunt and uncle = $100.00The total amount that the person had will be the addition of all the amount that he already had and those that he was given. This will be calculated thus:
$10.00 + $10.00 + $30.00 + $100.00 = $150.00
Therefore, the total amount that the person will have is $150.00

que es suma y resta de fracciones homogeneas
Answer:
responder
Step-by-step explanation:
Para sumar y restar fracciones, sus denominadores deben ser iguales. Por tanto, sumar o restar fracciones homogéneas es más fácil, dado que ya tienen el mismo denominador.
Answer:
Recuerda que cuando se suman fracciones homogéneas se hace lo mismo que cuando se suman objetos del mismo tipo. Por ejemplo, la suma tres décimos más dos décimos da como resultado cinco décimos: , por la misma razón que sumar tres vacas más dos vacas da como resultado cinco vacas.

What are the solutions to the quadratic equation below?
3x2 +16x + 21 = 0
Answer:
-3 and -7/3
Step-by-step explanation:
You could solve by factoring.
To do that, you find 2 numbers that multiply to 21, but add up to 16 when you multiply one of them by 3.
In this case, 3 and 7 would work, because 3*3 + 7 = 16, and 3 * 7 = 21.
Therefore, we can factor the equation to (3x+7)(x+3).
The solutions of the equations are -3 and -7/3.

Find the value of a. Then find the angle measures of the quadrilateral.
Answer:
a = 60
Step-by-step explanation:
Since it is a quadrilateral, the sum of interior angles is equal to 360°. Now you have to create an equation to solve this question. To create an equation, you have to add all the interior angles to 360°.
The equation would be 2a°+a°+a°+2a° = 360°.
Then you would simplify it to 6a° = 360.
You would divide 6 on both sides to get to a° = 60.
Therefore, the value of a is 60.

Answer:
x=2
Step-by-step explanation:
hope it helps
please mark as Brainliest
Answer:
x = 2
Step-by-step explanation:
For me it's easier to work with decimals than fractions, so I converted 3/4 to .75
.75(x + 18) = 15
.75x + 13.5 = 15
That was just distributing the .75 but here is where it gets a bit confusing.
.75x + 13.5 = 15
-13.5 -13.5
.75x = 1.5
Divide both sides by .75 to isolate the variable.
x = 2

SOMEONE PLEASE HELP ASAP!!!
Answer:
Step-by-step explanation:
Recall that (a-b)(a+b) = a^2 - b^2
So,
(x-2i)(x+2i) = x^2 - (2i)^2 = x^2+4
(x+i-i)(x+1+i) = (x+1)^2 + 1 = x^2 + 2x + 2
(x-2+2i)(x-2-2i) = (x-2)^2 + 4 = x^2 - 4x + 8

the following angles. Explain your reasoning.
F
E
D
В.
38 A.
1. BCD
2. ZECF
3. ZDCF
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°
