neonofarm [45]3 years ago
6 0

Step-by-step explanation:

\frac{3}{4} x +  \frac{7}{8}  = 4 \frac{1}{4}

\frac{3}{4} x =  \frac{17}{4}  -  \frac{7}{8}

\frac{3}{4} x =  \frac{34}{8}  -  \frac{7}{8}

\frac{3}{4} x =  \frac{27}{8}

3x \times 8 = 27 \times 4

24x = 108

x =  \frac{108}{24}

x =  \frac{9}{2}

What does communitive property mean
madreJ [45]
What you meant was the "commutative" property.

So we can say that when adding:

<em>"<u>Commutative</u> means that the order does not make any difference in the result."</em>

Example:

5 + 6 = 6 + 5

a + b = b + a

The commutative property does not hold for subtraction.

Example:

4 - 1 ≠ 1 - 4

a - b ≠ b - a

Ok, now does the commutative property hold true for multiplication?

2 x 3 = 3 x 2

2 x 3 x 4 = 4 x 3 x 2

Yes.

What about division?

12 ÷ 4 ≠ 4 ÷ 12

The commutative property does not hold for division.

The measure of ABD is (0.18x + 67) degrees and the measure of CBD is (0.07 + 48) degrees. Find the value of X
LUCKY_DIMON [66]

Answer:

See Explanation

Step-by-step explanation:

Given

ABD = 0.18x +67

CBD = 0.07x + 48

Required

Find x

The question is incomplete as the relationship between ABD and CBD is not stated.

Assume ABD = CBD

The solution is:

0.18x + 67 = 0.07x + 48

Collect like terms

0.18x - 0.07x= - 67  + 48

0.11x= -19

Solve for x

x = -\frac{19}{0.11}

x = -172.72

Assume ABD and CBD are supplementary

The solution is:

ABD + CBD=180

0.18x + 67 + 0.07x + 48 = 180

Collect like terms

0.18x + 0.07x  = - 48 - 67 + 180

0.25x  = 65

Solve for x

x = \frac{65}{0.25}

x = 260

Assume ABD and CBD are complementary

The solution is:

ABD + CBD=90

0.18x + 67 + 0.07x + 48 = 90

Collect like terms

0.18x + 0.07x  = - 48 - 67 + 90

0.25x  = -25

Solve for x

x = \frac{-25}{0.25}

x = -100
