Which of the following best describes the equation below?
ivann1987 [24]

Answer:

B.

no real solutions

Step-by-step explanation:

2(x + 11) + 5x = 7x - 22

Distribute

2x+22 +5x = 7x -22

Combine like terms

7x +22 = 7x-22

Subtract 7x from each side

7x-7x+22 = 7x-7x-22

22 = -22

This is never true so there are no solutions

Sheldon harvests the strawberries and tomatoes in his garden.
shtirl [24]

Answer:

A. 3 13/20

B.3.8 kg

C.Strawberries

Step-by-step explanation:

In order to solve this we just need to find the amount of strawberries he picked, and if he picked 1 2/5 less in the morning and in the morning he picked 2 1/4, we just add that up to know how much he picked in the afternoon:

1\frac{2}{5}+ 2\frac{1}{4}\\1 \frac{2(4)}{20}+ 2\frac{1(5)}{20}\\1 \frac{8}{20}+ 2\frac{5}{20}\\\\3\frac{13}{20}

So in the afternoon he picked 3\frac{13}{20}.

Now he picked 5 3/10 kg of tomatoes but 1.5 were rotten, we just have to withdraw the rotten from the total:

5\frac{3}{10} -1\frac{1}{2} \\5\frac{3}{10} -1\frac{5}{10} \\4\frac{3-5}{10} \\3\frac{13-5}{10} \\3\frac{8}{10}

So now we know that he picked 3\frac{8}{10} kg of good tomatoes.

If he picked in the afternoon and the morning 5.05 kg of strawberries, he picked more strawberries than tomatoes.

If 8 cakes cost £4.00 how much would 3 cakes cost?
zzz [600]
Hello!

To calculate how much 3 cakes would cost, we must first find the cost of each individual cake.

To do this, we must divide the cost of 8 cakes by 8 cakes.

4.00 ÷ 8 = 0.5

This means that each individual cake costs $0.50. Multiply this by 3 to find the cost of 3 cakes.

0.50 × 3 = 1.50

Therefore, 3 cakes would cost $1.50.
