Answer:
a. yes
Step-by-step explanation:
If 16 - u = -4 and u = 20:
16 - 20 = -4
The equaton is correct, therefore the given value of u is the solution to the equation.
Answer:
Standard Description: Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions. (Grade 4 expectations in this domain are limited to fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100.)

Answer:
14 ft
Step-by-step explanation:
If 196 ft is the area of the sandbox, two equal sides must multiply to equal 196. 14×14=196
Answer:
4) 50,000
5) 900,000
Step-by-step explanation:
In Front end rounding what we do is we focus on first two digit of the number if the second digit number is greater than or equal to 5 we add the first digit by 1.
4) 50,987
here we can clearly see that the first two digit is 50 and second digit is not equal to 5 then rounding will be equal to 50,000.
5) 851,004
here we can clearly see that the first two digit is 85 and second digit is equal to 5 then we will round it 8+1=9
hence rounded number will be 900,000
