Step-by-step explanation:

to "solve" this I need an equation.

this whole expression must be equal to something.

without that I can only try to simplify the expression.

remember that

a/b / c/d = ad / bc

so, here we have

3a/(((a²/x) - 1)(a/x - 1)) = 3a/(a³/x² - a²/x - a/x + 1) =

= 3a/(a³/x² - a²/x - a/x - a/a) =

= 3a/((a²/x² - a/x - 1/x - 1/a)×a) = 3/(a²/x² - a/x - 1/x - 1/a)

Answer:

a) ∠EAB = 180° - 90° - 30° = 60°

∠EBA = 180° - 90° - 60° = 30°

a) ∠EBA = 30°

b) ∠DCA = 180° - 90° - 30° = 60°

∠EBA ≅ ∠DAC, ∠EAB ≅ ∠DCA, ∠AEB ≅ ∠CDA

ΔEBA ≅ ΔDAC because of the AAA postulate

c) EB ≅ DA, EA ≅ DC, AB ≅ CA

d) AB = CA given

sin ∠EAB = EB/AB (sin 60°) EB = (0.8660)AB

cos ∠EAB = EA/AB (cos 60°) EA = (0.5)AB

cos ∠DAC = AD/CA (cos 30°) AD = (0.8660)CA

sin ∠DAC = CD/CA (sin 30°) CD = (0.5)CA

ED = EA + AD

ED = (0.5)AB + (0.8660)CA

since AB = CA, ED = 1.366CA

since EB = (0.8660)AB and AB = CA, then EB = 0.866CA

since CD = 0.5CA,

EB + CD = 0.866CA + 0.5CA = 1.366CA

EB + CD = 1.366CA

1.366CA = 1.366CA

Proof: ED = EB + CD

Can someone help me with this?

Answer:

1) $4+5=9$ .

2) $2+(-6)=-4$

3) $-3+(-7)=-10$

4) $(-7)+3=-4$

5) $9+(-4)=5$

6) $-1+4=3$

7) $5+(-5)=0$

8) $-3+(-6)=-9$

Step-by-step explanation:

In the given number lines, rightarrows represent positive integers and leftarrows represent negative integers.

In first number line we have two rightarrows.

Rightarrow from 0-4 = 4

Rightarrow from 4-9 = 5

So, required sum is $4+5=9$ .

Similarly,

$2+(-6)=-4$

$-3+(-7)=-10$

$(-7)+3=-4$

$9+(-4)=5$

$-1+4=3$

$5+(-5)=0$

$-3+(-6)=-9$

Randy has two 28-pound blocks of ice for his snow cone stand. 1). How many pounds of ice does randy have at his snow cone stand?

dalvyx [7]

Randy has 56 pound blocks of ice for his snow cone stand

Tons of ice is 0.028 tons or $\frac{7}{250} \text{ tons }$

Solution:

Randy has two 28-pound blocks of ice for his snow cone stand

1). How many pounds of ice does randy have at his snow cone stand?

Calculate the total pounds that Randy has

Total pounds = 2 x 28 = 56

Thus Randy has 56 pound blocks of ice for his snow cone stand

2) How many tons of ice is there?

Total pounds of ice = 56 pounds

So we have to convert 56 pounds to tons

Use the conversion factor

1 pound = 0.0005 ton

Therefore, 56 pounds is equal to,

56 pound = 0.0005 x 56 tons = 0.028 tons

Thus in decimal we got, 0.028 tons

Convert to fraction form,

$0.028 = \frac{0.028}{1000} \times 1000 = \frac{28}{1000} = \frac{7}{250}$

Thus tons of ice is 0.028 tons or $\frac{7}{250} \text{ tons }$
