X + 7 < 2x +7
therefore
<span>x < 2x
</span>x > 0
another:
25 + 7 > 10 + 7
therefore
25 > 10

Answer:
26, 37, 40, 48
Step-by-step explanation:
Whole numbers between 20 and 50 will have 10s digits in the range 2–5.
When 4 is added to these numbers, we get ...
2+4 = 6
3+4 = 7
4+4 = 8
5+4 = 9
When 4 is subtracted from these numbers, we get ...
2-4 = -2
3 -4 = -1
4 -4 = 0
5 -4 = 1
__
The numbers we can make using the given 10s digits and their corresponding 1s digit(s) are ...
26, 37, 40, 48
__
We note that any number with a 10s digit of 5 and a 1s digit other than 0 will be out of range.
Answer:
(a)ΔLAW≅ ΔWKL
(b) ASA rule of Congruency
Step-by-step explanation:
It is given that AW⊥WL and WL⊥KL, also ∠AWL=∠KLW ( Each 90°) and ∠ALW=∠LWK( Alternate angles) from the figure.
From ΔLAW and ΔWKL, we have
∠AWL=∠KLW ( Each 90°)
WL=WL (Common)
∠ALW=∠LWK( Alternate angles)
Therefore, by ASA rule of congruency,
ΔLAW≅ ΔWKL.
Hence proved.
That the foreign exchange rate between the US dollar and the Danish krone is 1:2.50 means that USD 1 = Dk 2.5
From that you create the conversion factor => 1 = Dk 2.5 / USD 1
Now use the conversion factor to convert USD 5 to Dk => USD 5 = USD 5 * Dk 2.5 / USD = 12.5 Dk.
