Please I need help with this problem

Answer: shorter: 24 longer: 41

Step-by-step explanation: we need to write an equation. x+(2x-7)=65. We don’t need the parentheses, but I put them so it would make it a bit more clear. Simplify: 3x-7=65. Add 7 to both sides: 3x=72. Divide by three: 72/3=24 Now we know the shorter piece is 24. 24x2-7=48-7=41. We know these are correct because 24+41=65

Chukwu, Abdul and kunle are to share $142, such that Abdul gets $11.00 less than Chukwu and $7.00 more than Kunle. How much is C

Elena-2011 [213]

Answer:

Chukwu's share is of $57.

Step-by-step explanation:

This question is solved by a system of equations.

I am going to say that:

Chukwu's share is x.

Abdul's share is y.

Kunle's share is z.

Chukwu, Abdul and kunle are to share $142

This means that $x + y + z = 142$

Abdul gets $11.00 less than Chukwu

This means that:

$y = x - 11$

$7.00 more than Kunle.

This means that:

$y = z + 7$

So

$z = y - 7$

$z = x - 11 - 7$

$z = x - 18$

How much is Chukwu's share?

We want to find x, so:

$x + y + z = 142$

$x + x - 11 + x - 18 = 142$

$3x - 29 = 142$

$3x = 171$

$x = \frac{171}{3}$

$x = 57$

Chukwu's share is of $57.

There is a mountain with 45 bat caves in a row. Every cave has at least 2 bats and there are 490 bats in all. Any 7 caves in a r

sergiy2304 [10]

Answer:

12 bats

Step-by-step explanation:

Let us number the bat caves from 1 to 45 and divide them into 5 parts:

a) 1

b) 2 to 29 ( $7\times 4=28$ bats)

c) 30

d) 31 to 44 ( $7\times2=14$ bats)

e) 45

It is given that any 7 caves in a row has 77 bats. Hence, the total number of bats in part b and d = $(4\times77)+(2\times77)=462$ bats.

There remains $(490-462)=28$ bats in cave number 1, 30 and 45.

Now, our question demands the maximum possible number of bats in cave 30.

Minimum number of bats in a cave is 2. So we shall put 2 bats in the last cave, which gives us $7\times2=14$ bats in the first cave.

Therefore, the number of bats in cave number 30 = $(28-2-14)=12$ bats.
