I’m not the best at math, but ⬇️

For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y

The angle marked a = 146 Work out the angle marked x.

notka56 [123]

Answer:

<h2>34 degrees</h2>

Basic facts:

<em>Corresponding angles are sometimes known as 'F' angles.</em>

angles in a straight line add up to 180

Step-by-step explanation:

To find the other side of <em>a</em> we follow the Basic fact annd do

180-146

=34

following the rule, we know that this is a flipped F

An F is a corresponding angle

therefore f is 34

Dave is comparing the circumferences of several trees in his yard. The oak tree is 0.539 meters in circumference, the ash tree h

stepan [7]

Answer: c. elm

Step-by-step explanation:

Given : The circumference of the oak tree= 0.539 meters

= $0.539\times100=53.9\text{ cm}$ [∵ 1 m = 100 cm] (1)

The circumference of the ash tree= 0.509 yards

$=0.509\times3\text{ feet}$ [∵ 1 yard = 3 feet]

$=0.509\times3\times 30.48\text{ cm}$ [∵ 1 foot = 30.48 cm]

$=46.54296\approx46.54\text{ cm}$ (2)

The circumference of the elm tree = 6281.70 millimeters

$=\dfrac{6281.70}{10}=628.17\text{ cm}$ (3)

The circumference of the poplar tree = 0.000385 miles

$=0.000385 \times5280\text{ feet}$ [∵ 1 mile = 5280 feet]

$=0.000385 \times5280\times30.48\text{ feet}$ [∵ 1 foot = 30.48 cm]

$=61.959744\approx61.96\ \text{ cm}$ (4)

From (1) , (2) , (3 ) and (4) it is clear that

46.54< 53.9 < 61.96 < 628.17

Hence, the elm tree has the greatest circumference.

What is 0.95 in simplest form

solong [7]

$0.95 \times \frac{100}{100} = \frac{95}{100} = \frac{19 \times 5}{20\times 5}\\\\ = \boxed{\bf{\frac{19}{20}}}$

0.95 in simplest form is 19/20
