HELP! 7th grade math! GIVE CORRECT ANSWER AND YOU WILL GET BRAINLIEST!!
Ksenya-84 [330]

Answer:

ED = 4 units

Step-by-step explanation:

Observing the figure given to us, we can deduce the following:

=>CE = EA (because point E is the midpoint of CA)

Therefore, if CE = EA = x unit, CA = 2x

=>Also, CD = DB (because point D is the midpoint of CB)

Therefore, if CD = DB = y, CB = 2y

Thus, CA/CE = CB/CD = 2 (2x/x = 2y/y)

Going by the above ration we got comparing the ratio of the corresponding sides of ∆CAB and ∆CED (2:1), we can conclude that ∆CAB ~ ∆CED

Using the ratio of the corresponding sides of ∆CAB to ∆CED = (2:1), measure of segment ED is calculated below:

AB/ED = 2/1

8/ED = 2/1

Cross multiply

8 × 1 = 2 × ED

Divide both sides by 2

8/2 = ED

ED = 4 units

*NEED HELP!*

Answer and Step-by-step explanation:

Hello!~

Let's~answer~your~question!

So,~for~this~equation,~we~need~to~use ~the~distributive~property~of ~multiplication.~but,before~we~start~to~solve  this~equation,~let's~get~to~know~what

distributive ~property ~of~multiplication~means!

<em><u /></em>

<em><u>Distributive property of multiplication :</u></em>  

Distributive~property~of~multiplication~states~thatwhen~a~~number~is~multiplied

by~the ~sum ~of~ two~ numbers, the~ first~ number ~can~ be ~distributed ~to both ~of~those numbers~and~multiplied~by~each~of~them separately.

→ a*(b+c)=a*b*+~a*c  

<em><u>Now, that we know what it means let's apply it in our equation:</u></em>

<em><u /></em>(2*x)+(2*7)=36<em><u /></em>

<em><u /></em>

<em><u>Now, we simplify:</u></em>

<em><u /></em>2x+14=36<em><u /></em>

<em><u /></em>

<em><u>Divide both sides by 2 in the equation:</u></em>

<em><u /></em>\frac{2x+14}{2} =\frac{36}{2}<em><u /></em>

<em><u /></em>

<em><u>Simplify :</u></em>

<em><u /></em>x+7=18<em><u /></em>

<em><u /></em>

<em><u>Thus, the first correct step is option B,</u></em>

<em><u /></em>then~comes,~option~"A"~then,~option~"F"~as~shown~above The~remaining~options~are~not~enough~information~to~solve~the~given equation:(x + 7) = 36.

Can somebody help me I'm about to cry yall.
Kobotan [32]

Answer:

a,c,f

Step-by-step explanation:

, 1 gallon = 8 fluid oz so if its 2 u multiply 8 by 2

5 gallons and if its 8 oz each 8x5=40 oz

1 ,1/4  if 1 gallon is 8 we need to find what 1/4 of 8 is so u divide it and u get 2 and 8 plus 2 = 10

there might be more but i dont think there is
