HELP ASAP CAUSE ITS DUE TODAY AND I DIDN'T FINISH IT!!!!!! <br><br><br>im sorry-!
Serjik [45]

Answer: 1 = 8 cups because 2 x 4 = 8.

2. 35... 7 x 10 = 70, 70 / 2 = 35

      1  

3.  20.53 + 1.55 + 0.02..        line up decimals!

<u> +    1.55</u>

   22.08

4. Mean is average.

so add up all the numbers and divide by the amount of numbers you added

18+9 = 27, 27 + 15 = 42, 42 + 11 = 53, 53 + 13 = 66, 66 + 15 = 81.

81 divided by 6 = 13.5 or 13 1/2.

5. c = 5b

b=55

c = 5 x 55

5 x 55 = 275.

c = 275.

<u>NEXT PAGE</u>

<u></u>

1. 48, 6 x 8 = 48.

2. 6, 4 x 3 = 12, 12 / 2 = 6

       1

3. 9. 12 + 5.78 + 6.01

   5.78

<u>+  6.01</u>

  20.91

4. 36 + 42 + 66 + 54 + 23 = 221, 221 / 5 = 44.2 or 44 1/5

5. t = 20c         c = 21

t = 20 x 21 = 420

t = 420.

I am trying to understand how to solve for X, then solve the equation
Alina [70]

Answer:

x = 16

m<Y = 34°

Step-by-step explanation:

∆XYZ is an isosceles ∆. An isosceles ∆ has two equal sides, as well as the bases of the isosceles triangle are congruent. In this case, therefore:

<X = <Z

(6x - 23)° = (4x + 9)

Solve for x

6x - 23 = 4x + 9

Collect like terms

6x - 4x = 23 + 9

2x = 32

Divide both sides by 2

x = 16

m<Y = 180° - (m<X + m<Z) (sum of ∆)

m<Y = 180 - ((6x - 23) + (4x + 9))

Plug in the value of x

m<Y = 180 - ((6(16) - 23) + (4(16) + 9))

m<Y = 180 - (73 + 73)

m<Y = 34°
