Step-by-step explanation:
Based on the given conditions,
Formulate:(100-80)÷80
Calculate the sum or difference:20/80
Cross out the common factor:1/4
Multiply a number to both the numerator and the denominator:1/4×25/25
Write as a single fraction :25/4×25
Calculate the product or quotient :25/100
Rewrite a fraction with denominator equals 100 to a percentage:25%
Answer : 25%
(c)*(d)=8*30+8*4=8*34,=>
c=8
d=34
a+b>a-b, =>a+b=d, a-b=c; =>
{a+b=34
{a-b=8, =>a=b+8 ;
(b+8)+b=34
2b=34-8
b=13
a=13+8=21
Answer: a=21; b=13; c=8; d=34.
Answer:
Less than 1 3/5: 1 3/5 * 1/3 and 3/4 * 1 3/5
Greater than 1 3/5: 1 2/3 * 1 3/5 and 1 3/5 * 1 1/4
Step-by-step explanation:
1 3/5 * 1/3
Since 1/3 is less than 1 , we are multiplying by less than 1, this will be less 1 3/5
1 2/3 * 1 3/5
1 3/5 * 1 2/3
Since 1 2/3 is greater than 1 , we will get a number greater than 1 3/5
3/4 * 1 3/5
1 3/5 * 3/4
Since 3/4 is less than 1, we will get a number less than 1 3/5
1 3/5 * 1 1/4
Since 1 1/4 is greater than 1 , we will get a number greater than 1 3/5
so when we add to the function outside of the parentheses of (x)^3, we are moving the graph in the up down direction so it would look like x^3 but shifted up 2 units. the way to easily know which one it is, plug in zero for x in the original and 0^3 is zero so we know the original fuction will go through the origin so the function who's center is is only shifted up (because it's positive 2) two units so graph 1
note: the reason i know that what looks like a center point is actually at the origin is because f(x)= x^3 is a very famous graph that you should know the shape of :)
Answer:
Step-by-step explain
3n - 2 = n + 10. add 2
3n = n + 12 subtract n from both sides
2n = 12. divide by 2
N = 6
