Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{x = 4}}}}}$

Step-by-step explanation:

$\sf{5x - 4 = 4x}$

Move 4x to left hand side and change it's sign

Similarly, move 4 to right hand side and change it's sign

$\longrightarrow{ \sf{5x - 4x = 4}}$

Collect like terms

$\longrightarrow{ \sf{x = 4}}$

Hope I helped!

Best regards! :D

Steps to solve:

5x - 4 = 4x

~Subtract 5x to both sides

-4 = -x

~Divide -1 to both sides

4 = x

Best of Luck!

Simplify.

Alika [10]

Solution:

Note that:

Given expression: (x² + 4x) − (x² + 6x − 3)

Remove the brackets

(x² + 4x) − (x² + 6x − 3)
=> x² + 4x - x² - 6x + 3

Combine like terms

x²(1 - 1) + x(4 - 6) + 3
=> x²(0) + x(-2) + 3
=> -2x + 3

suppose Tomas buys a total of 30 baseball and football cards in week 5 . how many of each would he have to buy to keep the same

Charra [1.4K]

Answer:

18 baseball cards
12 football cards

Step-by-step explanation:

The only relationship shown in the table is in week 1, where the ratio of baseball to football cards is ...

baseball : football = 9 : 6

In week 1, the total of these numbers is 15. You want the total in week 5 to be 30, double the total in week 1. So, Thomas needs to purchase double the numbers he purchased in week 1:

18 baseball cards
12 football cards

Comment on the attachment

This table came from another question you posted, a question with no content other than the table. The blue numbers are blanks in the original table that have been filled in so as to keep the same 3:2 proportion in each week. They appear to have no bearing on this question.

What is the lateral surface area of the cone?

hoa [83]

Answer:

135 pi centimeters squared

Step-by-step explanation:

Hello!

where la is lateral surface area

$first \: the \: formula \: for \: the \: lateral \: surface \: are \: of \: cone \: is \\ la = \pi \times r \times l \\ where \: r = radius \\ l = slant \: height \\ therefore.first \: find \: the \: radius(r) = \frac{d}{2} \\ r = \frac{18cm}{2} = 9cm \\ so \: as \: we \: have \: the \: radius \: we \: can \: solve \: for \: the \: la \\ la = \pi \times r \times l \\ la = \pi \times (9cm) \times (15cm) \\ la = 135\pi \: cm {}^{2}$

Nicole deposited $2,000 at 6% simple interest. How long will it be before she has $2,600 in her account?

coldgirl [10]

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &2,600\\
P=\textit{original amount deposited}\to& \$2,000\\
r=rate\to 6\%\to \frac{6}{100}\to &0.06\\
t=years
\end{cases}$

solve for "t"
