I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14
11.4=q-4.29+2.14
11.4=q-2.15
13.55= q
13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20
Answer: 3 times the sum of r and d squared minus 2 times the sum of r and d squared
we write the statement in terms of expression
⇒3×(r+d)²-2×(r+d)²=y
→y=(r+d)²
Answer:
35-22=x
35-22=13
Step-by-step explanation:
Include units if necessary:
$35-$22=$13
Step1) divide 1st term by the 1st term
so, 5x divide by 5x^3 which is x^2
step2) distribute to ALL terms
then multiply 4 (your 2nd term) by the x^2 (quotient)
step3) subtract
so the 5x^3 you get from 5x and x^2 is positive... you subtract it from the 5x^3 inside. And your result from distribution should be 4x^2 which you subtract
step4) repeat
and u continue that all the way through!
