Answer 1

М+в=160
м+к=142
в+к=154
в>к на 18
м>к на 6
м<в на 12
160-12=148
148/2 + 12 =74+12=86-вишня,74- малина
154-86=68-клубника

Answer 2

Calculation of the Number of Jars of Jam

To determine the number of jars of each type of jam displayed in the store, we can use the given information:

- Jars of cherry and raspberry jam: 160 - Jars of raspberry and strawberry jam: 142 - Jars of cherry and strawberry jam: 154

Let's assign variables to represent the number of jars for each type of jam: - Let C represent the number of jars of cherry jam. - Let R represent the number of jars of raspberry jam. - Let S represent the number of jars of strawberry jam.

Based on the given information, we can set up the following equations:

1. C + R = 160 (Equation 1) 2. R + S = 142 (Equation 2) 3. C + S = 154 (Equation 3)

To solve this system of equations, we can use substitution or elimination. Let's use the elimination method:

Adding Equation 1 and Equation 2, we get: (C + R) + (R + S) = 160 + 142 C + 2R + S = 302 (Equation 4)

Subtracting Equation 3 from Equation 4, we get: (C + 2R + S) - (C + S) = 302 - 154 2R = 148 R = 74

Substituting the value of R into Equation 1, we get: C + 74 = 160 C = 160 - 74 C = 86

Substituting the value of R into Equation 2, we get: 74 + S = 142 S = 142 - 74 S = 68

Therefore, the number of jars of each type of jam displayed in the store is as follows: - Cherry jam: 86 jars - Raspberry jam: 74 jars - Strawberry jam: 68 jars

Please note that these calculations are based on the given information and the assumption that there are no other types of jam in the store.

I hope this helps! Let me know if you have any further questions.
