First, you need to substitute the value of x in all of the x spots.
2x+3
2(3)+3. Us PEMDAS to solve the problem.
6+3
9

A ladybug's length is 2cm. Measure it in meters. And Explain your thinking.

trasher [3.6K]

1m = 100cm.

so since the ladybug is 2cm.

you divide 2 by 100, which you will get 0.02m (divide by 100 means moving the dot two times to the left. thats why it leaves you 0.02m)

Subtract 8-4 1/2. A. 3 B. 4 C. 4 1/2 D. 3 1/2

Leokris [45]

1.
An expression of the form $a \frac{b}{c}$ is called a "compound fraction"

Compound fractions can be written as simple fractions by multiplying c to a, and then adding the product to c as follows:

$a \frac{b}{c}= \frac{c.a+b}{c}$

for example,

$4\frac{1}{2}$ can be written as:

$4\frac{1}{2}= \frac{2.4+1}{2}=\frac{9}{2}$

2.

when we subtract or add a fraction $\frac{m}{n}$ from an integer k,

we first write k as a fraction with denominator n. We can do this as follows:

$k=k. \frac{n}{n}= \frac{kn}{n}$

for example, if we want to subtract $\frac{9}{2}$ from 8,

we first write 8 as a fraction with denominator 2:

$8=8. \frac{2}{2}= \frac{8.2}{2}= \frac{16}{2}$

3.

Thus,

$8-4 \frac{1}{2}= \frac{16}{2}- \frac{9}{2}= \frac{16-9}{2}= \frac{7}{2}$

4.

The simple fraction 7/2 is not an option, so we write it as a compound fraction as follows:

$\frac{7}{2}= \frac{6+1}{2}= \frac{6}{2}+ \frac{1}{2}=3+ \frac{1}{2}=3\frac{1}{2}$

(So write 7 as the sum of the largest multiple of 2, smaller than 7 + what is left. In our case these numbers are 6 and 1, then proceed as shown)

Answer:

x = -4

Step-by-step explanation:

EM = 5x

ET is half of EM so this statement is true: 5x = 2(3x + 2)

Solve for x.

5x = 2(3x +2)

Distribute 2.

5x = 6x + 4

Isolate x.

-x = 4

Divide -1 out.

x = -4

Q1: Payments of $ 670 are being made at the end of each month for 5 years at an interest of 8% compounded monthly. Calculate the

Jlenok [28]

Answer:

So, the present accumulated value is, $ 49557.69

Step-by-step explanation:

According to the question, payments of $ 670 are being made at the end of each month for 5 years at an interest of 8% compounded monthly. So, present accumulated value, =

$ $\sum_{x = 1}^{60}670 \times (1 + \frac{8}{12 \times 100})^{x}$
