Answer: 48 model cars.
Step-by-step explanation:
1. You know that the ratio of the number of model cars that Jim owns to the number of model cars Terrence owns is 4:3.
2. Let's call the number of model cars that Jim owns is
, therefore, you can solve the exercise as following:
![\frac{4}{3}=\frac{x}{36}\\x=\frac{36*4}{3}\\x=\frac{144}{3}\\x=48](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%3D%5Cfrac%7Bx%7D%7B36%7D%5C%5Cx%3D%5Cfrac%7B36%2A4%7D%7B3%7D%5C%5Cx%3D%5Cfrac%7B144%7D%7B3%7D%5C%5Cx%3D48)
3. Therefore, Jims owns 48 model cars.
Answer:
<h3>5</h3>
Step-by-step explanation:
Given the expression
2a^3−10ab^2+3a^3−ab^2−7
We are to find the coefficient of a^3
First is to collect the like terms;
2a^3−10ab^2+3a^3−ab^2−7
= 2a^3+3a^3−10ab^2−ab^2−7
= 5a^3-11ab^2-7
From the resulting equation, you can see that the coefficient of the term having a^3 is 5
Answer:
56 carrots
Step-by-step explanation:
Because 7 x 8 is 56
Answer:
Option A
Step-by-step explanation:
Let's denote:
x is the number of albums Teresa downloads.
y is the number of individual songs Teresa downloads.
=> 9x + y = 25
Let's check:
Option A: x = 2 and y = 7 => 9 x (2) + 7 = 18 + 7 = 25 => valid
Option B: x = 1 and y = 8 => 9 x (1) + 8 = 9 + 8 = 17 => invalid
Option C: x = 4 and y = 5 => 9 x (4) + 5 = 36 + 5 = 41 => invalid
Option D: x = 3 and y = 6 => 9 x (3) + 6 = 27 + 6 = 33 => invalid
