3(4-2x)=5-3(1-5x)
12-6x=5-3(1-5x)
12-6x=2(1-5x)
12-6x=2-10x
10-6x=-10x
10=-4x
5/-2=x

4 times the sum of a number and 8 gives 25

KatRina [158]

Answer:

4×(x+8)=25.

use the 4 to multiply the numbers in the bracket.

which is 4x+32=25.

then collect like terms which is...

4x=25-32...

4x=-7.

x=-7/4= -1.75 or -1 whole number 3/4.

Use a calculator to find the value of t. Round to the nearest thousandth. T=ln 1.5-3

spin [16.1K]

Answer:

-2.595

Step-by-step explanation:

When inputting this function into your calculator, we need to be aware of a couple things:

1.) his is ln(1.5) - 3, and not ln(1.5-3). Negative numbers cannot be put into the natural log function.

2.) That is because lnx is another way of saying $log_{e}x$ . If you're having trouble finding ln on the calculator, use logx/loge (an odd rule that you'll learn soon from the looks of it.)

Give an example of fractions that you would compare by finding common denominators,and an example of fractions you would compare

creativ13 [48]

Answer:

Correct answer: 2/3 < 3/4

Step-by-step explanation:

We will compare the following two fractions:

2/3 and 3/4

First we will find common denominator:

The common denominator for 3 and 4 is 12, then we will multiply

first fraction with 4 and second with 3 and get:

8/12 and 9/12 and we conclude that 9/12 is greater than 8/12

respectively that 3/4 is greater than 2/3

Second we will find common numerator:

The common numerator for 2 and 3 is 6, then we will multiply

first fraction with 3 and second with 2 and get:

6/9 and 6/8 and we conclude that 6/8 is greater than 6/9, the reason is, the greater the fraction, the smaller the denominator

respectively that 3/4 is greater than 2/3

Can someone help me please

Mrac [35]

Step-by-step explanation:

sleeping in class ? :-)

these are our pure definition questions.

9. false

if the data was only defined for whole numbers, then that would be the only case, where that is true. but then, there would be no rounding.

the "significant figures" are the decimal places after the decimal point.

rounding it to one significant figure means rounding it to the first position after the decimal point.

10. True

see 9. for more details.

Using traditional methods, it takes 11.111.1 hours to receive a basic driving license. A new license training method using Compu

IgorLugansk [536]

Answer:

The value of the test statistic is -0.979

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 11.1 hours

Sample mean, $\bar{x}$ = 10.7 hours

Sample size, n = 24

Alpha, α = 0.05

Sample standard deviation, s = 2.0 hours

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 11.1\text{ hours}\\H_A: \mu \neq 11.1\text{ hours}$

We use two-tailed t test to perform this hypothesis.

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$t_{stat} = \displaystyle\frac{10.7 - 11.1}{\frac{2}{\sqrt{24}} } = -0.979$

Thus, the value of the test statistic is -0.979
