Answer:

Step-by-step explanation:

1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66

  A = width * lengh = 23 * 10 = 230

2. width = 7

 P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32

Answer:

4. area= 230cm^2 perimeter= 66cm

5. width= 7m  perimeter= 32m

Step-by-step explanation:

4. a = w*l

23cm*10cm=230cm^2

p= add all sides

23cm+23cm+10cm+10cm=66cm

5. w= a/l

63m^2/9m=7m

p= add all sides

7m+7m+9m+9m=32m

1. Solve the system using substitution
IgorC [24]
X + y = 8
y = 3

Well, because we know what y equals, we simply plug in 3 for y in the given equation.

x + y = 8

x + (3) = 8

Subtract 3 from both sides.

x = 8 - 3

So, x = 5

(5, 3)

Check work by plugging in x and y in the given equation.

x + y = 8

(5) + (3) = 8

8 = 8

So, our answer is (5, 3)

I am quite sure that you have given us the wrong equations, as none of these answers are correct.

~Hope I helped!~

Teo earns 47.25$ in 7 h of work at Beck’s Burgers. How much will he earn in 12 hours?
goldenfox [79]

Answer:

He will earn <u>$81</u> in 12 hours.

Step-by-step explanation:

Given:

Teo earns 47.25$ in 7 hours of work at Beck’s Burgers.

Now, to find the money he will earn in 12 hours.

As, given Teo earns 47.25$ in 7 hours of work.

So, to get the money he will earn in 12 hours we solve by using unitary method:

If Teo earns in 7 hours $47.25.

Then, in 1 hour he earns = \frac{47.25}{7}

Thus, in 12 hours he will earn = \frac{47.25}{7} \times 12

                                                 = 6.75\times 12

                                                 =  \$81.

Therefore, he will earn $81 in 12 hours.
