homework question for 4th grade math?

Question

The sum of two whole numbers is 75. The difference is19. What are the numbers?

Answer 1

Probably too young for algebra so just use trial and error. For example.

50+25 = 75 but 50-25 = 25.

So try numbers that are closer together:

45 + 30 = 75 but 45 - 30 = 15.

So try numbers a little farther apart.

47 + 28 = 75 and 47-28 = 19 . We are done.

Answer 2

!st number 2nd number Total Difference
===============================================
30 45 75 15
25 50 75 25
28 47 75 19

The 2 numbers are 28 and 47

Answer 3

47 and 28. 47-28=19 and 47+28=75.

Answer 4

You can set this up as two equations
x + y = 75
x - y = 19
then use substitution to find the numbers
x = 19 + y

19 + y + y = 75
19 + 2y = 75
2y = 56
y= 56/2=28

plug y back into one of the original equations
x - 28 = 19
x= 28 +19 = 47

Answer 5

the numbers are 47 and 28

Answer 6

47 and 28

Answer 7

the formulation for area of a rectangle is fairly common area=length * width so 5 squarein = 10 inches * ___ inches 5 = 10 * w or 5 =10w divide the two sides of equation via 10 5/10 = w a million/2 = w width is a million/2 inch. image a rectangle that is 2 x 5, you be attentive to that is 10 sq. inches 1x5 is 5 sq. inches 1x10 is 10 sq. inches a million/2 via 10 is 5 sq. inches what became throwing you off is the width is a fragment; yet that's what 4th grade is all approximately: fractions desire this helps
