8 0

Answer:

Angle z makes a 180° angle when added to the angle of 124° in the first image, because they are on the same side of a straight line. Just subtract 124 from 180. =56 For the second picture, angle m will be the same as angle z because of the properties involved.

I am so lost, please help

Answer:

$u=\frac{9}{t}-\frac{1}{2} a t$

Step-by-step explanation:

Step 1: Given equation: $9=\frac{1}{2} a t^{2}+u t$

To get u, by subtraction equality property subtract both sides of the equation by $\frac{1}{2} a t^{2}$ .

$\Rightarrow 9-\frac{1}{2} a t^{2}=\frac{1}{2} a t^{2}+u t-\frac{1}{2} a t^{2}$

$\Rightarrow 9-\frac{1}{2} a t^{2}=u t$

Step 2: By division equality property, divide both sides of the equation by t.

$\Rightarrow \frac{9-\frac{1}{2} a t^{2}}{t}=\frac{u t}{t}$

$\Rightarrow \frac{9}{t}-\frac{1}{2} a t=u$

Therefore, $u=\frac{9}{t}-\frac{1}{2} a t$ .

So, in Emily’s physics class, she got $u=\frac{9}{t}-\frac{1}{2} a t$ .

Henry packed some apples in a box. The total mass of the box and the apples was 16 240 g. He packed some strawberries in a simil

icang [17]

Step-by-step explanation:

x = mass of apples

y = mass of strawberries

z = mass of the box

x = 3y

x + z = 16240

y + z = 6350

let's subtract the second from the first equation

x + z = 16240

- y + z = 6350

-----------------------

x - y + 0 = 9890

using the first identity in that result gives us

3y - y = 9890

2y = 9890

y = 4,945 g

x = 3y = 3×4945 = 14,835 g = the mass of the apples
