The system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000
Let c represent the number of cookies and let b represent the number of brownies.
Since Genie want to make more than 125 cookies and brownies altogether, hence this is given by:
c + b ≥ 125 (1)
Also, Genie has a total of 2,000 grams of flour, hence:
8c + 12b ≤ 2000 (2)
Therefore the system of inequalities models correctly the number of cookies is c + b ≥ 125 and 8c + 12b ≤ 2000

I need help with these 2 problems I cant figure out.
I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.
2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)
Next, I add 20 on both sides.
2x + 90 + 3x = 200º
I combine like terms (2x and 3x)
5x + 90 = 200º
I subtract 90 from both sides.
5x = 110º
Divide 110 by 5 to get x.
x = 22
======
For problem two, I label all the angles I know.
49º + 80º + r = 180º
I add 80 and 49.
129º + r = 180º
I subtract 180 and 129 and get 51º, which is your angle for R.
For angle X, you know that angle R plus angle X equals half of a circle, which is 180º
We know from before that 129º is 180º without R, so X is 129º

Given − 13 x − 23 ≥ 7x + 3,, which property is used below? 3 (−13 x − 23) ≥ 3(7x + 3)
The property used is Division property of equality to get the resulting equation since we divided both sides by 3
Given the inequality expression
3 (−13 x − 23) ≥ 3(7x + 3)
We are to know which of the property is used to arrive at − 13 x − 23 ≥ 7x + 3
We can see that both sides of the expression were divided by 3 as shown:
[tex]\frac{3(-13x-23)}{3} \geq \frac{3(7x+3)}{3}\\-13x-23 \geq 7x+3\\[/tex]
From the division, we will see that the property used is Division property of equality to get the resulting equation since we divided both sides by 3

Larry works for a tree farmer and needs to plant new saplings (young trees). He can plant 27 saplings per hour. He needs to plant 178 total saplings and has already planted 16 saplings.
Which equation and answer shows the number of hours (h) it will take for him to plant the rest of the saplings?
Answer:
27h+16=178 I believe would work as an equation for this problem
Step-by-step explanation:
The required time to plant the rest of the saplings is 6 hours, and 27 + 16 = 178 is the required expression.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let the number of hours be h,
He can plant 27 saplings per hour.
He needs to plant 178 total saplings and has already planted 16 saplings.
So, according to the quesiton,
27h + 16 = 178,
27h = 162
h = 162/27
h = 6
Thus, the required time to plant the rest of the saplings is 6 hours,

en un restaurante se usan 70 gramos por cada porción de arroz por persona.Si un día se preparan 4760 gramos de arroz ¿cuántas porciones se obtendrán?
Queremos saber cuantas porciones de arroz se preparan dado que conocemos cuantos gramos de arroz se utilizan.
Se prepararon 68 porciones.
Lo que sabemos en principio es que, por cada porción de arroz, se necesitan 70 gramos de arroz.
Sabemos que en total se utilizan 4,760 gramos de arroz. Para saber cuantas porciones se prepararon, hay que tomar el cociente entre la cantidad total utilizada y lo que se usa para cada porción.
Esto nos da:
4,760g/70g = 68
Es decir, se prepararon 68 porciones.

Pls help me with this one
Answer:
It's not proportional
Step-by-step explanation:
The first 2 days are proportional because, they travel at an increment of 60 miles an hour.
But, on the third day, it is not proportional because they travel at an increment of 90 miles an hour.
360 / 4 = 90
120 / 2 = 60
60 / 1 = 60
Answer:
The answer would be yes and no!! But, it would be no!
Step-by-step Explanation:
Yes: On Monday and Tuesday, those would be proportional because they are just counting by 60´s. 60 plus 60 would give you 120.
No: On Wednesday, this ¨person¨ traveled 360 miles in 3 hours. Now, you aren´t counting by 60´s anymore. Even though you started out counting by the 60´s, doesn´t mean you will finish like that.
60´s:
1 hour = 60 mi
2 hours = 120 mi
3 hours should be = 180 miles, not 360 Because:
360 mi would be equal to 6 hours. Do you see where I´m going with this?
Hope that helps you so you can put it in a mathematical way. Have a great day!!
