Alex, this is the solution to the exercise:

If the original amount is 320 and the end amount is 112, this is a decrease.

Now, let's estimate the percentage, as follows:

• Difference = Original amount - End amount

• Difference = 320 - 112

• Difference = 208

In consequence,

• Percentage of decrease = Difference/Original amount * 100

• Percentage of decrease = 208/320 * 100

• Percentage of decrease = 0.65 * 100

• Percentage of decrease = 65%

Answer:

Part 3) Miguel scored 29 points and Alonzo scored 25 points

Part 4) Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years

Step-by-step explanation:

Part 3) Let

x ----> the number of points that Miguel scored

y ---> the number of points that Alonzo scored

we know that

$x+y=54$ ----> equation A

$x=y+4$ ----> equation B

substitute equation B in equation A and solve for y

$(y+4)+y=54\\2y=54-4\\2y=50\\y=25$

Find the value of x

$x=25+4=29$

the solution is the point (29,25)

That means ----> Miguel scored 29 points and Alonzo scored 25 points

Part 4) Let

x ----> Morgan's age

y ---> Mr Santos' age

we know that

$x+y=44$ -----> equation A

$x=y-15$ ----> equation B

substitute equation B in equation A and solve for y

$(y-15)+y=44\\2y=44+15\\2y=59\\y=29.5$

Find the value of x

$x=29.5-15=14.5$

the solution is the point (14.5,29.5)

That means ----> Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years

34 divided 5323 in simple form

joja [24]

The value when 34 is divided by 5323 is 0.00639.

<h3>What is division?</h3>

It should be noted that division simply means the opposite of multiplication. It represents the way numbers are combined in order to make new numbers.

The steps include:

1: Take the dividend's first digit starting from the left in step one. Verify if this digit exceeds or is equal to the divisor.

2. Next, divide it by the divisor, and write the result as the quotient on top.

3. Subtract the outcome from the digit, and then put the difference below.

4: Decrease the dividend's subsequent digit (if present).

5: Carry out Step 4 again.

In this case, 34 divided 5323 will be 0.00639. It should be noted that this illustrates a decimal.

If 4 : 9 is equivalent to (5x+13) : 63, then what is the value of x?

Aleksandr [31]

$\large{\underline{\underline{\pmb{\sf{\color{yellow}{Answer:}}}}}}$

The value of x is 3

Step-by-step explanation:

$\textsf{\underline{\large{To find :-}}}$

The value of x

$\textsf{\underline{\large{Given :-}}}$

4 : 9 = (5x + 13) : 63

$\textsf{\underline{\underline{\large{Solution :-}}}}$

we can write this as

$\sf \frac{4}{9} = \frac{(5x + 13)}{63}$

Now we will cross multiply the values

$\sf 4 \times 63 = 9(5x + 13) \\ \\ \sf 252 = 45x + 117 \\ \\ \sf 252 - 117 = 45x \\ \\ \sf 135 = 45x \\ \\ \sf \frac{135}{45} = x \\ \\ \sf \orange {3 = x}$

5 biscuits cost 30p altogether how much do 7 biscuits cost?

andrezito [222]

First we want to find how much an individual biscuit costs.
If 5 biscuits costs 30p, then
5 x 1 biscuit = 30p
divide both sides by 5
1 biscuit = 6p

If one biscuit costs 6p, and we want to know how much 7 biscuits cost, then:

7 x 6p =42p

7 biscuits costs 42 p
