So they are asking to subtract, therefore it is 8.10-3.49=4.61 SO HE SPENT $4.61 Hope this helped!
Answer:
The polynomial is:
12 m² - 11 m n + 2 n².
Step-by-step explanation:
( 3 m - 2 n ) · ( 4 m - n ) =
= 12 m² - 3 m n - 8 m n + 2 n² = 12 m² - 11 m n + 2 n²
Answer:
The polynomial is:
12 m² - 11 m n + 2 n².
Let the total number of students be x;
given that the ratio of girls to boys is 5:3, then:
The equation that represents the number of girls will be:
5/8x
The equation that represents the number of boys will be :
3/8x
The equation that represents the total number of boys and girls will be:
5/8x+3/8x
B] suppose there are g number of girls. The equation that represents the number of boys in terms of number of girls will be:
(ratio of boys to girls)×(number of girls)
3/5×(g)
=(3g)/5
Answer:
D
Step-by-step explanation:
Use the FOIL method and multiply it out, and you should get
16x^2+28x-28x-49
Simplify that and you get the answer.
