<span>seven less than (-7) than the product of twice a number (2x) is greater than (>) five more than (+5) the same number (x)
2x-7>x+5
treat the > sign as an equals for now
2x-7=x+5
subtract x from both sides
x-7=5
add 7 to both sides
x=12
put the > sign back in
x>12</span>

Step-by-step explanation:
This root can be rewritten as:
Since 6487209 is a multple of 3, the expression can be rearranged as follows:
2162403 is also a multiple of 3, then:
720801 is a multiple of 3, then:
240267 is a multiple of 3, then:
80089 is a multiple of 283, then:
Answer:
1. 30°
2.
3. 20cm
4. 5cm
Step-by-step explanation:
for the first one:
we have the triangle RVT and we know that
so = 180
so
for the second one
we know by specials right triangles that the sides are
divide by x and get
for the third one
again by 30-60-90 triangle we know that
for the fourth one
here we can use excersie 3 and the ratio of XY:YC = 1:1
that means they are equal so
XY=YC
XY = 5
68.054 I think. Hope it helps
You have to add on to zeros to the number 2 and because there is a decimal point, that counts as a zero added. the stages:
2.2
22
220
your answer is 220 cm
