q= 6
r= 7
work--
Multiply 1st column by -2:
-30q+8r=-124
5q+8r=86
Subtract 2nd column from the first column:
-35q= -210
Solve for q:
q=6
Subtract q=6 by any of the two equations, so:
-30q+8r=-124
-30*6+8r=-124
Solve for r:
r=7
Answer:
15in
Step-by-step explanation:
Area=width x length
Width=375/25 = 15in
First you would follow the Order Of Operations:
Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction
Second step: You will add 6 and 4 together since addition came before subtraction in the Order Of Operations.You would get 10.
Your equation should now look like: 13-10.
Last step: You would subtract 10 from 13 since there are no other numbers
Your answer should then be: 3
HOPE THIS HELPS! ^_^
Step-by-step explanation:
By rule of bodmas rule
= 1 - 31 + 6 + 3 × 8
= 1 - 31 + 6 + 24
= 1 - 31 + 5 + 24
= - 30 + 5 + 24
= - 25 + 24
= -1
Now without using bodmas rule
= 1 - 31 + 6 + (4 - 1). 8.
=-30+6+4+(4-1)×8
=-23+4+(4-1)×8
=-19+4+(4-1)×8
=-15+(4-1)×8
=-15+3×8
=-15+24
=-9
MARK AS BRAINLIST IF IT IS USEFUL
Take any fraction, proper or improper, and then multiply both the numerator and denominator by any number you want.
An example is one-half (1/2)
1/2 = 2/4 = 4/8 = 12/24 = 25/50 = 50/100 = 1000/2000 = 1024/2048
All of those are the same 1:2 ratio, just expressed in different forms.
