Equality Properties

Step-by-step explanation:

Step 1: Define

7x/3 < 2

Step 2: Solve for x

Multiply both sides by 3: 7x < 6
Divide 7 on both sides: x < 6/7

Here we see that any value x smaller than 6/7 would work as a solution to the inequality.

Answer:

$the \: floor \: has \: the \: following \: dimensions \to \\ \boxed{ length \: of \: 37.35 \: meters} \\ and \\ \boxed{width \: of \: 5.35 \: meters}$

Step-by-step explanation:

$let \: the \: width \: of \: the \: floor \: be \to \: w \\ let \: the \: length \: of \: the \: floor \: be \to \: l = w + 32 \\ but \: the\: are a\: of \: the \: rectangular \: floor \: is \to \\ a = lw = 200 \\ w(w + 32) = 200 \\ {w}^{2} + 32w = 200 \\ {w}^{2} + 32w - 200 = 0 \\ w = \frac{ - 32 + \sqrt{32 {}^{2} - 4(1)( - 200) } }{2(1)} \\ \boxed{ w = 5.35} \\ hence \\ l = 5.35 + 32 \\ \boxed{l= 37.35}$

Need help with school please help

Katarina [22]

Answer:

Angle 1 - 51

Angle 2 - 39

Angle 3 - 90

Angle 4 - 51

Angle 5 - 17

Angle 6 - 129

Step-by-step explanation:

Angle 1 = 180 - 90 - 39 = 51

Angle 2 = 90 - Angle 2 (51) = 39

Angle 3 = 90

Angle 4 = 180 - Angle 2 (39) - Angle 3 (90) = 51

Angle 5 = 180- 90 - 34 -39 = 17

Angle 6 = 180 - Angle 4 (51) = 129

Help, please simplify.. thank you

$\bf \cfrac{3.7\times 10^{-12}(42)}{(.000000025)(4.0\times 10^{-15})}\implies 
\cfrac{37\times 10^{-13}(42)}{(25\times 10^9)(4\times 10^{-15})}$

$\bf \cfrac{37(42)\times 10^{-13}}{25(4)\times 10^910^{-15}}\implies 
\cfrac{1554\times 10^{-13}}{100\times 10^{9-15}}\implies 
\cfrac{1554\times 10^{-13}}{1\times 10^2\times 10^{9-15}}
\\\\\\
\cfrac{1554\times 10^{-13}}{10^{2+9-15}}\implies \cfrac{1554\times 10^{-13}}{10^{-4}}\implies 1554\times 10^{-13}\times 10^4
\\\\\\
1554\times 10^{-13+4}\implies 1554\times 10^{-9}\implies \cfrac{1554}{10^9}\implies 0.000001554$

Tanya made 75 flyers for five volunteers in her club to hang up around her school she gave 15 flyers to the first volunteer 22 f

AysviL [449]

Answer:

The remaining volunteers would get 11 flyers each.

Step-by-step explanation:

Given:

Total number of flyers = 75

Total number of volunteers = 5

Number of flyers for 1 volunteer = 15 flyers.

Number of flyers to 2nd volunteer = 22 flyers.

number of flyers to 3 volunteer = 16 flyers.

We need to find the remaining number of which are equally distributed in remaining number of volunteers.

Solution:

First we will find the number of flyers already distributed.

number of flyers already distributed is equal to sum of Number of flyers for 1 volunteer, Number of flyers for 2 volunteer and Number of flyers for 3 volunteer.

framing in equation form;

number of flyers already distributed = $15+22+16 = 53\ flyers$
