All triangle equal 180 degrees so add the 53 and 90 and it’s 90 because it’s a right triangle 53+90= 143 then subtract 143 from 190 so 190- 143= 47 so the missing degree is 47
Step-by-step explanation:
The expression for he earning of Allison and her allowance is as follows :
15x+100y
Part A
Variables are x and y. Coefficients are 15 and 100.
Part (B)
There are two terms in this expression. + is used to separate the terms. 15x and 100y are the terms.
Part (C) As $15 shows her earning from allowances. Hence, 15x shows allowance.
152
Step-by-step explanation:
45 seconds = 45/60 minutes = 3/4 minutes . Number of copies = 4*32 + (3/4)*32 = 128 + 24 = 152
The LCD here is 12(5) = 60.
We must rewrite <span>7/12 - 2/5 with 60 as common denominator.
Doing this, we get 35/60 - 24/60 = 11/60 (answer)</span>
We find the common factor and reduce the fraction:
10/15 = (10/5) / (15/5) = 2/3
15/20 = (15/5) / (20/5) = 3/4
2/6 = (2/2) / (6/2) = 1/3
2/8 = 1/4
3/12 = 1/4
3/9 = 1/3
4/6 = 2/3
5/15 = 1/3
5/20 = 1/4
6/8 = 3/4
6/9 = 2/3
9/12 = 3/4
