Anna35 [415]

Answer:

Mrs. Fowler will get $9$ free pizza. And she needs two more coupon for the next pizza.

Step-by-step explanation:

Given that pizza stand gives a free pizza for every $8$ coupons.

And Mrs. Fowler has $78$ coupons.

Part (a)

How many free pizzas can Mrs. Fowler get if she has $78$ coupons?

We will divide total number of coupons $78$ by $8$ coupons.

$\frac{78}{8}=9\frac{6}{8}$

When we divide we get quotient as $9$ , with a remainder of $6$ . So, Mrs. Fowler will get $9$ free pizza.

Now, part (b)

If Mrs. Fowler adds two more coupons that will turn remainder $6$ into $6+2=8$ .

So, she can have next pizza.

Two cars are traveling down the highway with the same speed. If the first car increases its speed by 1km/hr, and the other car d

Olegator [25]

Answer:

The speed of the cars is $32 \frac{km}{h}$

Step-by-step explanation:

First we must first have the clear concept that $speed=\frac{distance}{time}$ or $s=\frac{d}{t}$

Our question is the speed of the cars then the variable to clear will be s.

Let's raise the equation for each car taking into account that we have the following data:

Car 1: $s_{1}=s+1$ , $t_{1}=2$ and $d_{1}= d_{2}$

Car 1: $s_{2}=s-10$ , $t_{2}=3$ and $d_{1}= d_{2}$

The two cars travel the same distance so we will raise the distance formula for each car and then match them.

<em>Car 1</em>

$d_{1}=s_{1}*t_{1}$

$d_{1}=(s+1)*2$

$d_{1}=2s+2$

<em>Car 2</em>

$d_{2}=s_{2}*t_{2}$

$d_{2}=(s-10)*3$

$d_{2}=3s.30$

$d_{1}=d_{2}$

$2s+2=3s-30$

$2+30=3s-2s$

$32=s$

The speed of the cars is 32 km/hr

Someone quickly help! thanks!

Goryan [66]

Answer:

x=23°; θ=87°

Step-by-step explanation:

These two angles create what is known as supplementary angles, or 2 angles that add up to 180°. We know this because all horizontal lines are 180° on either side. Since we know the total value of these two angles should equate to 180°, we can set up a simple equation:

$93+(3x+18)=180$

Now, using algebra, we can solve for x:

$111+3x=180$

$3x=69$

$x=23$

Plugging x back into the equation, we get:

$3(23)+18=87$

Therefore, the total angle is equal to 87° and x is equal to 23°.

Hope this helps!
