Answer:
its blurry for me sorry
Step-by-step explanation:
B. <span>–4.37 < –1.63 is the true statement. -4.37 is less than -1.63
</span>
A. <span>–4.28 > –3.56 * should be less than
</span>C. <span>5.7 < 5.63 * should be greater than
</span>D. -13.90 > 4.63 *should be less than
In dealing with negative numbers, the greater the negative number is, the lesser its value. 4.37 is a greater number than 1.63 in its positive form, however, its negative form give 4.37 a lesser value than 1.63 in its negative form.
Answer:
Well.. its already in standard form..
but even if u want u can write it as 8 X 10^(-1)
Step-by-step explanation:
Standard form is used for quite big decimal numbers
like : 0.2356
We can write it as 2.4 X 10^(-1)
P-Q should be -11a^2+4b^2+ab
Step-by-step explanation:
Let the numbers are 4x and 7x. According to the question if each number is increased by 20, the ratio becomes 7 : 9.
Then,
( 4x + 20 ) : ( 7x + 20 ) = 7 : 9
9( 4x + 20 ) = 7( 7x + 20 )
9( 4x ) + 9( 20 ) = 7( 7x ) + 7( 20 )
9( 20 ) - 7( 20 ) = 7( 7x ) - 9( 4x )
2( 20 ) = 49x - 36x
40 = 13 x
40 / 13 = x
Therefore, number are :–
4 x = 4( 40 / 13 ) = 160 / 13
7 x = 7( 40 / 13 ) = 280 / 13
