Answer:
Step-by-step explanation:
2915 can stay as it is; 15.458 should be rounded down to 15. Then we have
2915-15, or 2900 (which is a very reasonable estimate).
Answer:
correct choice is 1st option
Step-by-step explanation:
Two given triangles have two pairs of congruent sides: one pair of length 7 units and second pair of length 8 units. The third side is common, i.e the lengths of third sides are equal too.
Use SSS theorem that states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Thus, given triangles are congruent by SSS theorem.
Change one to 5/5 because that is equal to one and then subtract the top numbers to get 4/5. Hope this helped.

Answer:
The number is 37
Step-by-step explanation:
The given parameters are;
The unit digit of a two-digit number = 4 + The tens digit
2 × The two-digit number = 1 + The reversed number
Let x represent the unit digit and y represent the tens digit, we have;
x = 4 + y
2 × yx = xy + 1
Which gives;
2 × yy+4 = 2y2y+8
xy + 1 = 4 + yy + 1
y + 1 = 2y + 8 - 10 (we assume that the product of 2 and the unit digit is more than 10 so we subtract 10 from the product to equate the unit digits of the two numbers
10 + 1 - 8 = 2y - y
10 - 7 = y
y = 3
x = y + 4 = 3 + 4 = 7
x = 7
Therefore, the number = 37.
