You haven't provided the expressions to choose from.
4⁻² × 7⁻² = (4×7)⁻² = 28⁻² = 1/28²
There are 659 blocks
<em><u>Solution:</u></em>
The number in ones place is 9
Let's denote number in the tens place with x
The number in the hundreds place is one more then the tens place
Therefore,
The number in hundreds place is 1 + x
Those two numbers equal 11
Which means tens place number and hundreds place number sums up to 11
tens place + hundreds place = 11
x + 1 + x = 11
2x = 11 - 1
2x = 10
x = 5
Thus number in tens place = x = 5
Number in hundreds place = 1 + x = 1 + 5 = 6
The number is represented as:
Number = (Number in hundreds place)(number in tens place)(number in ones place)
Number = 659
Thus 659 blocks are there

The cost of 1 knife is £5.52
Step-by-step explanation:
The given is:
- A knife is three times the cost of a spoon
- 9 spoons and 12 knives cost £82.80
We need to find the cost of 1 knife
Assume that the cost of one spoon is x and the cost of one knife is y
∵ The cost of one spoon = x
∵ The cost of one knife = y
∵ The cost of a knife is three times the cost of a spoon
-That means y is 3 times x
∴ y = 3 x ⇒ (1)
∵ 9 spoons and 12 knives cost £82.80
∴ 9 x + 12 y = 82.80 ⇒ (2)
Now we have a system of equations to solve it
Substitute y in equation (2) by equation (1)
∴ 9 x + 12(3 x) = 82.80
∴ 9 x + 36 x = 82.80
- Add the like terms in the left hand side
∴ 45 x = 82.80
- Divide both sides by 45
∴ x = 1.84
- Substitute the value of x in equation (10 to find y
∵ y = 3(1.84)
∴ y = 5.52
The cost of 1 knife is £5.52
