0.75h + 3 = 12 <br> What's the answer?
kykrilka [37]

Answer:

h = 12

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

0.75h + 3 = 12

<u>Step 2: Solve for </u><em><u>h</u></em>

  1. Subtract 3 on both sides:                    0.75h = 9
  2. Divide 0.75 on both sides:                  h = 12

<u>Step 3: Check</u>

<em>Plug in h into the original equation to verify it's a solution.</em>

  1. Substitute in <em>h</em>:                    0.75(12) + 3 = 12
  2. Multiply:                               9 + 3 = 12
  3. Add:                                     12 = 12

Here we see that 12 does indeed equal 12.

∴ h = 12 is a solution of the equation.

Which BEST describes the system of equations? y = 4x + 3 y = 2x − 4 A) Consistent B) Inconsistent C) Consistent and Dependent D)
cestrela7 [59]

Answer:

D) Consistent and Independent

Step-by-step explanation:

The system of equations,

a_{1} x+b_{1} y+c_{1} =0 and

a_{2} x+b_{2} y+c_{2} =0

is consistent and independent if \frac{a_{1} }{a_{2}} \neq \frac{b_{1} }{b_{2}}

The system is consistent and dependent if \frac{a_{1} }{a_{2}} =\frac{b_{1} }{b_{2}} =\frac{c_{1} }{c_{2}}

The system is inconsistent if \frac{a_{1} }{a_{2}} =\frac{b_{1} }{b_{2}} \neq \frac{c_{1} }{c_{2}}

Now, in the given system

4x - y + 3 = 0 and

2x - y - 4 = 0

\frac{a_{1} }{a_{2}} =\frac{4}{2} =2

\frac{b_{1} }{b_{2}} =\frac{-1}{-1} =1

So, \frac{a_{1} }{a_{2}}\neq \frac{b_{1} }{b_{2}}

Hence, the given system is consistent and independent.

There are 2 rectangles. One was 1.2 cm by 3.4 cm. The other was measured 2.1 cm by 1.7 cm. How much is the perimeter?
ELEN [110]

Answer: See explanation

Step-by-step explanation:

Perimeter of a rectangle is given as:

= 2(length + breadth)

First rectangle measures 1.2 cm by 3.4 cm. The perimeter will be:

= 2(1.2+ 3.4)

= 2(4.6)

= 2 × 4.6

= 9.2cm

Second rectangle measured 2.1 cm by 1.7 cm. The perimeter will be:

= 2(2.1 + 1.7)

= 2 × 3.8

= 7.6cm

Total perimeter = 9.2cm + 7.6cm = 16.8cm
