Question

на выставке в зоологическом музее Лизу заинтересовали мадагаскарские тараканы и пауки тарантулы она насчитала 12 голов и 78 ног Сколько пауков увидела Лиза на выставке Запиши решение ответ​

Answer 1

Ответ:

3 паука увидела Лиза на выставке

Пошаговое объяснение:

Как известно, у тараканов 6 ног, а у пауков 8 ног.

1) 12*6=72 (ног) если бы на выставке были только тараканы

2) 78-72=6 (ног) лишние, а значит принадлежат паукам

3) 8-6=2 (ноги) разница между количеством ног у таракана и паука

4) 6:2=3 (паука) было на выставке

Answer 2

Calculating the Number of Spiders Lisa Saw at the Exhibition

To calculate the number of spiders Lisa saw at the exhibition, we can use the information provided about the number of heads and legs she counted on the Madagascar cockroaches and tarantula spiders.

Lisa counted 12 heads and 78 legs in total. Let's calculate the number of spiders she saw at the exhibition.

First, we need to determine the number of spiders based on the number of heads and legs.

We know that: - Each cockroach has 6 legs. - Each tarantula spider has 8 legs.

Let's denote: - C as the number of cockroaches. - T as the number of tarantula spiders.

We can create a system of equations based on the given information: 1. C + T = 12 (the total number of heads) 2. 6C + 8T = 78 (the total number of legs)

Solving this system of equations will give us the values of C and T, representing the number of cockroaches and tarantula spiders Lisa saw at the exhibition.

Let's solve the system of equations to find the values of C and T.
