Answer:

A.

Step-by-step explanation:

x is the number you don't know or you can classify it as a number. It states that a number (x) is increased by 13 which is referring to addition. So when you do so you get 43. This would be written as x +13=43

The areas of the squares adjacent to two sides of a right triangle are 32units^2 and 32 units^2
adoni [48]

Answer:

x = 8 units.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

<em>The areas of the squares adjacent to two sides of a right triangle are 32 unit square and 32 units square. Find the length,x, of the third side of the triangle</em>

My answer:

  • Let a is the side length of the 1st square

The area of the 1st square is equal to 32 units square

<=> a^{2} = 32

<=> a = 4\sqrt{2} units

  • Let b is the length  of the 2nd  square

The area of the 2nd square is equal to 32 units square

<=> b^{2} = 32

<=> b = 4\sqrt{2} units

  • Find the value of x

Applying the Pythagoras Theorem, we have:

x^{2} = a^{2} + b^{2}

<=> x^{2}  = 32 + 32  

<=> x^{2} = 64

<=> x = 8 units

Hope it will find you well.

Dennis and Ivy share some sweets between them in the ratio 7:4 Dennis got 42 sweets. How many does ivy get
MrRa [10]

Answer:

Ivy = 24

Step-by-step explanation:

Given

Dennis : Ivy = 7 : 4

Required

Determine the amount of sweet Ivy gets when Dennis = 42

We have:

Dennis : Ivy = 7 : 4 and

Dennis = 42

Substitute 42 for Dennis in Dennis : Ivy = 7 : 4

42 : Ivy = 7 : 4

Convert to fraction

\frac{42}{Ivy} = \frac{7}{4}

Cross Multiply:

Ivy * 7 = 42 * 4

Divide through by 7

\frac{Ivy * 7}{7} = \frac{42 * 4}{7}

Ivy = \frac{42 * 4}{7}

Ivy = 6* 4

Ivy = 24

What are the steps to getting the value of x in 4(2x - 11) + 15 = 21 and explanation for each step?
tester [92]

4*(2x - 11) + 15 = 21

8x - 44 +15 = 21

8x = 21 + 44 - 15

8x = 50

x = 50 : 8

x = 6.25 or 25/4
