Answer:
Step-by-step explanation:
Do u see any similarities between the numbers? Both 12 and -4 have a variable(N). 8 and -7 dont have a variable, so u have to calculate them individually.
One thing to remember is just because there is a minus sign(-) or a plus sign(+) does not mean its addition or subtraction. its the value of the number. the sign to the left of the number is its value. so left of 12 is plus(+), so its a positive. left of 4 is a minus sign(-) so its a negative 4. lastly, left of 7 is minus sign(-), which means its negative 7. now u add.
lets add the variables first:
12n + (-4n) = 8n
add the regular numbers:
8 + (-7) = 1
so its 8n + 1
√36 = plus or minus 6. These results are real, rational, integer, whole and natural, and yes, there can be more than one answer; that's because we're solving a quadratic equation. Note that both 6 and -6, when squared, yield 36.
a) 2:3
c) 4:1
e) 2:1
g) 10:1
i) 60:1
b) 24: 1
d) 8:1
f) 3:4
h) 100:1
j) 20:1
Step-by-step explanation:
a) 10:15 then divide each by 5 bc its a common denominator
c) 20:5 then divide each by 5 bc its a common denominator
e) 12:6 then divide each by 6 bc its a common denominator
g) 40:4 then divide each by 4 bc its a common denominator
i) 600:10 then divide each by 10 bc its a common denominator
b) 72:3 then divide each by 3 bc its a common denominator
d) 40:5 then divide each by 5 bc its a common denominator
f) 60:80 then divide each by 20 bc its a common denominator
h) 500:5 then divide each by 5 bc its a common denominator
j) 60:3 then divide each by 3 bc its a common denominator
You set it equal to 0 then solve. you would move 4 over to the other side so you would have 1/5w=-4 then multiply -4 by the opposite of 1/5 which is 5. and you get
w= -20
