Answer:

\huge\boxed{\sf 16}

Step-by-step explanation:

<u>Given expression is:</u>

= 10 + 3(12 ÷ (3x))

Put x = 2 nd use PEDMAS [Parenthesis Exponents Division Multiplication Addition Subtraction "in that order"]

= 10 + 3(12 ÷ (3)(2))

Solve Parenthesis

= 10 + 3(12 ÷ 6)

Now, Divide

= 10 + 3(2)

Now, Multiply

= 10 + 6

Now, Add

= 16

\rule[225]{225}{2}

Hope this helped!

Answer:

\huge\boxed{ \boxed{\tt \: 16}}

Step-by-step explanation:

Evaluate :

10 + 3(12 \div 3x)

When,

x = 2

Solution:-

\sf \implies10 + 3(12 \div 3x)

This expression may be rewritten as,

\sf \implies10 + 3 \bigg(\cfrac{12}{3x}  \bigg)

<u>Put 2 instead of x as x = 2</u> :-

<em>As we know that x is multiplied with 3 on this expression so,</em>

\sf \implies10 + 3 \bigg(\cfrac{12}{3 \times 2}  \bigg)

\sf \implies10 + 3 \bigg(\cfrac{12}{6}  \bigg)

<u>Cancel off 12 and 6</u>(By 6) :-

\sf \implies10 + 3 \bigg({\cfrac{ \cancel{12}}{ \cancel{6}} ^{2}   }\bigg)

\sf \implies10 + 3 (2)

According to BODMAS Rule we know that, First Multiplication and then addition.(According to this expression)

<u>So,Multiply 3 and 2</u> :-

\sf \implies10 +  3 \times 2

\sf \implies10 + 6

<u>Simply </u><u>add </u>:-

\sf \implies16

Hence, the answer of the given expression would be 16.

Please help me with question number 2
Mice21 [21]

Answer:

2. The area of the side walk is approximately 217 m²

3. The distance away from the sprinkler the water can spread is approximately 11 feet

4. The area of the rug is 49.6

Step-by-step explanation:

2. The dimensions of the flower bed and the sidewalks are;

The diameter of the flower bed = 20 meters

The width of the circular side walk, x = 3 meters

Therefore, the diameter of the outer edge of the side walk, D, is given as follows

D = d + 2·x (The width of the side walk is applied to both side of the circular diameter)

∴ D  = 20 + 2×3 = 26

The area of the side walk = The area of the sidewalk and the side walk = The area of the flower bed

∴ The area of the side walk, A = π·D²/4 - π·d²/4

∴ A = 3.14 × 26²/4 - 3.14 × 20²/4 = 216.66

By rounding to the nearest whole number, the area of the side walk, A ≈ 217 m²

3. Given that the area formed by the circular pattern, A = 379.94 ft.², we have;

Area of a circle = π·r²

∴ Where 'r' represents how far it can spread, we have;

π·r² = 379.94

r = √(379.94 ft.²/π) ≈ 10.997211 ft.

Therefore, the distance away from the sprinkler the water can spread, r ≈ 11 feet

4. The circumference of the rug = 24.8 meters

The circumference of a circle, C = 2·π·r

Where;

r = The radius of the circle

π = 3.1

∴ For the rug of radius 'r', C = 2·π·r = 24.8

r = 24.8/(2·π) = 12.4/π = 12.4/3.1 = 4

The area = π·r²

∴ The area of the rug = 3.1 × 4² = 49.6.

-4(2x-3)&gt;-28 please i need this result
Len [333]

-4 (2x - 3) > -28

Divide by -4 on both sides. Since we're dividing by a negative, we need to switch the sign.

2x - 3 < 7

Add 3 to both sides

2x < 10

Divide by 2 on both sides

x < 5

Need help fast please thanks

Answer:

c = 41 ft

Step-by-step explanation:

To solve this problem, we can use the pythagorean theorem, which is defined by the formula a^2+b^2=c^2. We are given both the lengths of the legs, so all we need to do is to plug them both in and solve for c:

9^2+40^2 = c^2\\c^2 = 81 + 1600\\c^2 = 1681\\c = 41

This is the first option.
