Answer: 72 cars.
Step-by-step explanation:
Let be "x" the number of toys that Moby had to start with.
According to the information given in the exercise, Moby sold half his toy car collection. This can be represented with the following expression:

Then he bought 12 more cars, giving a total amount of 48 toy cars.
Therefore, the equation that represents this situation is the equation shown below:

Now you must solve for "x" in order to find its value.
You get that this is:

Answer:
1/4
Step-by-step explanation:
Five bottles of sunscreen were shared equally among 20 campers. What fraction of a bottle for each camper use?
This question above is calculated as:
Number of bottles of sunscreen/Number of campers
= 5/20
= 1/4
Hence, fraction of a bottle for each camper use is 1/4
No it’s less than because it’s negative
Answer:
m∠R=76°
Step-by-step explanation:
∠STR=∠RST=(2x+2)° (base angles of isos triangle)
2(2x+2)+(3x+1)=180 (angle sum of triangle)
4x+4+3x+1=180
7x+5=180
7x=180-5
=175
x=175÷7
=25
Hence, m∠R = (3x+1)°
= [3(25)+1]°
= (75+1)°
= 76°
0 + (6/10) + (8/100) + (5/1000)
