Answer:
The smaller number is: 8
The bigger number is: 20
Step-by-step explanation:
Ok let's say the two numbers are x and y.
x is the smaller one, and y is the bigger one.
This is the equation to find x:
x + 4y = 88
x + y = 28
x - x + 4y - y = 88 - 28
3y = 60
y = 20
x + 20 = 28
x = 8
Answer:
70, 105, 140
Step-by-step explanation:
Answer:
44 units squared.
Step-by-step explanation:
The formula for area of a trapezoid is:
a = missing area
b1 = short base (5)
b2 = long base (17)
h = height (4)
(5 + 17) ÷ 2 = 11
11 × 4 = 44
area = 44
Answer:
-2 3/4 < -1 1/2
Step-by-step explanation:
Positives are always greater than negatives (Example: 2 is greater than -2).
This eliminates the first and last inequalities.
Smaller negative numbers are always greater than larger negative numbers (Example: -2 is greater than -4).
This eliminates the third unequality.
For the second given inequality, convert the fractions to share the same denominator.
-2 3/4 < -1 2/4
They are both negative numbers.
We know smaller negative are always greater than larger negative numbers.
This inequality aligns with this statement.
Therefore, only the second inequlity is true.
