Answer:
8, 18 and 36 respectively.
<h2>explanation</h2>
sum=54
1st number=x
2nd number=x+10
3rd number =2(x+10)=2x+20
x+x+10+2x+20=54
put the liketerms together
x+x+2x=54-10-20
4x=24
divide both sides by 4 to get
x=8
Input the other values
$768,
She had to pay $64 a month and there are 12 months in a year. So 64 x 12= 768
Answer:
We know that both snakes and lizards are species of reptiles.
the things that baby lizards can do but baby snakes can't are : Walking and Leaping , they both had a very different body structure. Since snakes can only move by slithering their muscle and scale, they had no abilities to walk and leaping as lizards have legs so they move around by using them while snakes don't have one. Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes.
Answer:
(b) -4.5
Step-by-step explanation:
Choosing the correct answer here is not the same as knowing what the correct value is.
<h3>Estimate</h3>
You know that √30 < √100 = 10, so the sum must be negative. That is, 10 subtracted from a positive number less than 10 will give a negative result.
You know that 25 < 30 < 36, so √25 < √30 <√36. That is, √30 will be between 5 and 6. If we say √30 ≈ 5.5, then the sum is ...
-10 +√30 ≈ -10 +5.5 = -4.5

Of course, a calculator can tell you the value to the desired precision.
