Bingel [31]

Answer:

first evening, 10 calls, second evening 80 calls, third evening, 20 calls.

Step-by-step explanation:

if the number of calls received during the first evening is X, then the number of calls received during the third evening is X+10 as the third evening received 10 more calls than first evening. The second evening received 4 times of third so 4X+10. Add them up together and put them equal to 110.

X+10+X+4X+40=110

6X+50=110

6X=110-50

6X=60

X=10

First evening, 10 calls,

second evening 80 calls; 4X+40, 4(10)+40=80

third evening 20 calls; X+10, (10)+10=20

135,000 mg =_____________ kg
kupik [55]
The correct answer for the question that is being presented above is this one: "<span>0.135 kg."</span>

the topic presented here is conversion.
Converting mg to kg.
1000000 mg = 1 kg
1 mg = 0.000001

So, from the given, 135,000mg, we need to divide it by 1000000 mg in order to get the kilogram conversion.

= 135000 / 1000000
= 0.135 kg.

What value completes the table?
Eddi Din [679]
Given f(x) = x^{5} +  (x+3)^{2}, find f(x), when x is equal to -1. 

Simply, you just need to substitute -1 into the given equation. 

f(x) = (-1)^{5} + ((-1)+3)^{2}
f(x) = -1 + 2²
f(x) = -1 + 4
f(x) = 3

The value that completes this table is the last choice, which is 3.
