Arnoldo needs to write this system in slope-intercept form. Which shows how he could do that? 3 x minus 2 y = 6. 0.4 (20 y + 15)

kotegsom [21]

Answer:

y = three-halves x minus 3

Step-by-step explanation:

Subtract 3x from both sides of the original equation.

-2y = -3x +6

Divide by -2

y = 3/2x -3

I don't understand this question can someone help me with this please, please explain!! and thank you for the help!! If u dont k

Gekata [30.6K]

Answer:

1. C) .4

2. B) 2 1/4

3. D) 3 5/8

Step-by-step explanation:

1. The question is asking what fraction (represented in decimal form) did Maria spend. To find this, divide 18/45 because Maria spent $18 of her $45. When you complete this calculation, you get .4

2. When you look at where the line ends, it's at the first quarter line after the 2, meaning that the line is 2 and one quarter or 2 1/4

3. 8 times 3 is 24, which is the closest multiple of 8 to 29. However, since there is still 5 left over (which still needs to be divided by 8) it would be represented by the mxed fraction.

A road crew can pave 2/5 km in 1 1/2 hours.how many km of road can they pave in 10 hours?

andrey2020 [161]

Answer:

8/3 km

Step-by-step explanation:

we can represent the given information on a table:

Kilometers time (hours)

2/5 ⇔ 1 1/2

and since we want to know how many kilometers (x) will be paved on 10 hours:

Kilometers time (hours)

2/5 ⇔ 1 1/2

x ⇔ 10

The relationship these 3 numbers have can be described by using the <u>rule of three,</u> which is to multiply the cross quantities on the table (2/5 by 10) and then divide by the remaining amount (1 1/2):

x = $\frac{2}{5}*10$ ÷ $1\frac{1}{2}$

x = $\frac{20}{5}$ ÷ $1\frac{1}{2}$

we use $1\frac{1}{2}=\frac{3}{2}$

x = $\frac{20}{5}$ ÷ $\frac{3}{2}$

and we make the division:

x = $\frac{20}{5}$ ÷ $\frac{3}{2}$ = $\frac{20*2}{5*3}=\frac{40}{15}$

we simplify the fraction by dividing the numerator and denominator both by 5, and we get the result:

x = $\frac{8}{3}$

thus, in 10 hours the crew will pave 8/3 km. Which is about 2.66 km.

tatuchka [14]

$\bf ~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$590\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\dotfill &3 \end{cases} \\\\\\ I=(590)(0.04)(3)\implies I=70.8$
