Answer:

x = 5

Step-by-step explanation:

Since both triangles are similar hence;

m<CAB = m<CDE

Given theta

m<CAB = 50degrees

m<CDE = 10x

Substitute the given angles

50 = 10x

Swap

10x = 50

Divide both sides by 10

10x/10 = 50/10

x = 5

Hence the value of x is 5

Solve for t in terms of the other variables. <br> k= 3tm + rs

Lina20 [59]

Answer:

$t=\dfrac{k-rs}{3m}$

Step-by-step explanation:

It's like solving any equation, except we have letters instead of numbers .

k = 3tm + rs {subtract rs from both sides}

k - rs = 3tm {divide both sides by (3m)}

$\dfrac{k-rs}{3m}=t$ {swap sides}

$t=\dfrac{k-rs}{3m}$ m≠0

{m must be ≠0 because you cannot divide by 0. There is no t for m=0}

Hannah wants to save 1/3 of her allowance each week to buy a new dress that costs $45.00. if her allowance is $6.00 each week, h

Bess [88]

Answer:

It will take 22.5 weeks for her to save up to buy the dress.

Step-by-step explanation:

1/3 of $6.00 is 2.

(6 ÷ 3 = 2)

So she's saving $2 each week.

Now we need to divide $45 by $2 to get the number of weeks.

45 ÷ 2 = 22.5
