-2(t + 4 2/3) = 9 1/2

1 answer:

4 0

So you times the -2 with the bits inside the bracket so:
-2 x t= -2t
-2 x 4 2/3 = -9 1/3
So then that makes:
-2t - 9 1/3= 9 1/2
So to get what t equals you have to get it by itself so you add the -9 1/3 to both sides of the equation to get:
-2t=18 5/6
So then you divide by -2 on both sides to get
t=-9 5/12
Which is the answer. :-D

The measure of angle C is 89 degrees.

Step-by-step explanation:

The given polygon ABCD is a quadrilateral.

The property of a quadrilateral :

The sum of the consecutive angles add to 180°.

In this quadrilateral, the angles B and C are consecutive angles. So, the sum of angle B and angle C is equal to 180 degree.

Given that,

The measure of angle B = 2x+3
The measure of angle C = 2x+1

To find the value of x :

m∠B + m∠C = 180

(2x+3) + (2x+1) = 180

4x + 4 = 180

4x = 180 - 4

4x = 176

x = 176/4

x = 44

To find m∠C :

m∠C = 2x + 1

⇒ 2(44)+1

⇒ 88+1

⇒ 89°

The measure of angle C is 89 degrees.

U-3/4=4 please help me ty

Ne4ueva [31]

To solve the equation:

$\frac{u - 3}{4} = 4 \\ \frac{u - 3}{4} \times 4 = 4 \times 4\\ u - 3 = 4 \times 4 \\ u - 3 + 3 = 16 + 3 \\ u = 16 + 3 \\ u = 19$

Therefore, the answer is u=19.

Hope it helps!

Hunter's time for the 100-meter freestyle event was 57.9 seconds. His time for the second half of the race was 4.7 seconds slowe

Ratling [72]

Answer:

Step-by-step explanation:

Time for first race 57.9seconds

x=time for first half of race

x-4.7=second half of race

Equations is

x + (x-4.7)=57.9

2x-4.7=57.9

2x=57.9+4.7

2x=62.6

x=31.3

Check answer

31.3 + (31.3-4.7)=57.9

31.3 +26.6=57.9

57.9=57.9
