Answer:

a = -10

Step-by-step explanation:

33 - 4a = 73

To get <em>a</em> by itself, you must move 33 to the other side. To this, you must subtract it from both sides, canceling it out on the left side.

You will be left with: -4a = 73-33

Subtract 73 and 33, which will get you 40.

Now the equation is -4a = 40

To get <em>a </em>by itself, divide -4 into both sides. Doing this will isolate <em>a</em>.

The equation you will have after that is a = 40/-4.

Divide 40 by -4, which will get you -10.

Therefore, a = -10.

Question 1 of 3 NE A scale drawing of a fishing boat has a scale of 1 cmn to 2 meters. If the length of the fishing boat is 6 cm
bagirrra123 [75]

Answer:

12 meters

Step-by-step explanation:

Given

Scale= 1cm:2m

Required

Determine the measurement when the scale reads 6cm

Represent this scale with x;

Such that:

Scale = 6cm:x

Equate

Scale= 1cm:2m and Scale = 6cm:x

1cm:2m = 6cm:x

Express as fraction

\frac{1cm}{2m} = \frac{6cm}{x}

Cross Multiply

x * 1cm = 6cm * 2m

x * 1 = 6 * 2m

x = 6 * 2m

x = 12m

Answer:

H) 0.75

Step-by-step explanation:

4.5 divided by 6 is 0.75

We don't use remainders in algebra for the most part.  We have to do regular division.  I'll try to show it here:

By pythagorean theorem

a^2+b^2=c^2

We can find that PL is 12.65

and then by altitude theorem

MA*LA=PA^2

we can find the value of MA

12MA=16

MA=1.33

then by the pythagorean theorem

we can use to find PM

MA^2+PA^2=PM^2

so PM=4.22

then to find the are you multiply length by width

PM*PL

12.65*4.22

So the area is 53.38
